Going Vertical: How Vertical Farming Is Revolutionizing the Cannabis Industry

By Jeffrey L Garber
1 Comment

In the cannabis industry, it’s crucial to be able to predict the future, to adapt and survive in a competitive industry that is arguably regulated more closely than any other.

From licensing to buildout, there are a growing number of barriers to entering the cannabis industry as a cultivator. Those who are lucky to successfully establish a grow operation are well aware that one of the crucial hurdles is managing space to maximize facility efficiency and capacity.

To stay profitable, the more plants you can grow and harvest at a time in a continuous cycle, the better. From an economic and environmental perspective, managing cost, space and time comes down to automation and efficiencies. One of the most efficient ways we optimize is through the practice of vertical farming.

Vertical farming maximizes canopy square footage while minimizing Cost of Goods Sold (COGs) to produce high-quality cannabis at scale year-round, and the industry is slowly finding that this method is an incredibly efficient and profitable way to maximize cannabis output.

Yellow Dream Farm is our family-owned cannabis cultivation, manufacturing and distribution company based in San Bernardino County, California, often known as the Silicon Valley of cannabis. Our craft, boutique-style cannabis is grown from floor to ceiling in the 30,000-square-foot facility. We’re using cutting-edge technology that’s only come to market in the last five years and using a variety of sustainable practices. With environmental and feeding efficiencies, we’re able to harvest 300 pounds per week when compared to 150 pounds per week from a facility of the same size.

Vertical Farming for Space Optimization

Like any medical field, cannabis has seen large numbers of outside investments into the space, bringing ideologies and efficiencies from other time-tested industries. One such efficiency is vertical farming – a practice already seen in large-scale agriculture.

The Yellow Dream Farm vertical cultivation facility

We choose vertical farming to maximize our canopy square footage and minimize COGs to produce high-quality cannabis at scale. The barrier to entry into the cannabis industry is expensive, and you must utilize every square inch to stay profitable. We believe vertical farming is the most efficient and most profitable way to maximize output and our numbers can back that up; for example, we can produce double the amount of flower than the average single-tier room with the same square footage, without doubling the cost.

Our rooms contain double stacks to double room capacity by using ceiling heights instead of square footage. Even though vertical farming has larger start-up costs, we can maximize square footage and output, allowing us to get a better and faster ROI. Vertical farming can be done in many different ways but the way we built our facility was always with a sustainable outlook. We also look to improve and remove human error; with full irrigation control and crop steering technologies, we can recalibrate sensors, irrigation media and environmental sensors when needed based on successes, challenges or environmental constraints. Additionally, we have a few other sustainable practices that make a difference.

Water Conservation, Lighting and Automation

Being a California-based grower, water conservation is a key part of our operations. With San Bernardino County being located in the heart of the high desert, conserving water is not only a requirement but a competitive advantage. Our practices provide cost savings which we then pass along to our customers. Each cannabis plant on average requires between a half gallon and one gallon of water per day, which we then recirculate through condensate water from our A/C and dehumidifiers. All runoff nutrient water is re-filtered and reused to get the most out of our nutrients before discarding waste. Our freezer panel walls hold temperatures at consistent rates, and we have a fully automated system to dial in specific needs at any given time.

Lighting is another major environmental and capital cost. Our primary lighting system is LED technology, and we use LED spectrums to find which spectrum benefits the plant most. With LEDs, our energy consumption is 30 percent less.

Vertical Farming Is the Future of Cannabis and Agriculture

Vertical farming has been hailed as the future of many agricultural industries and cannabis is no different. We already see large vertical farms in most legal states, but surprisingly it’s still not a common style of growing. As the price per pound steadily declines in California, being able to keep COGs down will allow vertical farmers to sustain and thrive in this volatile industry.

In order to adapt, grow and leave a positive mark on the industry, we must pave the way for new styles of growing and utilizing new technology and science that was not available to growers in the past. We can use these advanced new technologies to make real-time changes to each sector of our facility and optimize both people power, and energy efficiency. And most importantly, we’ll be able to produce top-quality cannabis for adults to enjoy at affordable prices.

Leaders in Cannabis Formulations: Part 5

By Aaron Green
No Comments

Natural cannabinoid distillates and isolates are hydrophobic oils and solids, meaning that they do not mix well with water and are poorly absorbed in the human body after consumption. Cannabinoid oils can be formulated into emulsions to form a fine suspension in water to modulate bioavailability, stability and flavor.

Happy Chance is a cannabis infused products company offering better-for-you products to their customers. Happy Chance recently launched a low-glycemic index fruit bite line made from fresh ingredients, distinguishing them from traditional gummies. Splash Nano is a cannabis infused products ingredients company specializing in nano emulsions. Happy Chance utilizes Splash Nano technology in their fruit bites formulations.

We spoke with Katherine Knowlton, founder of Happy Chance, and Kalon Baird, co-founder and CTO of Splash Nano to learn more about their products and how they came to do business together. Prior to Happy Chance, Knowlton worked as a chef. Prior to Splash Nano, Baird was a consultant to the cannabis industry.

Aaron Green: Katherine, how did you get involved in the cannabis industry?

Katherine Knowlton, Founder of Happy Chance

Katherine Knowlton: I am a chef by trade. I went to culinary school in 2015. My partner also got into the cannabis space in 2017, which was right around the time when adult use cannabis became legal in California. As a chef, I am very passionate about cooking for optimal health and well-being. I noticed right away the abundance of candy- and sugar-laden products on the market. I set out to create a wellness driven product blending healthy, whole foods with a better value proposition, better-for-you and better-for-the-planet.

Green: Okay, great. Kalon, same question: how did you get involved in the cannabis industry?

Kalon Baird: I left a corporate job in 2011 and started cultivating in Southern California. I started to develop techniques for horticulture and developed a connection with the plant. I was a consultant for many years, and then decided to take a different path when legalization happened and got into the regulated manufacturing space. My goal was to bring new products to market to help satiate the demand for the infused category, the non-smokeable categories and to pursue niche product development.

Green: Tell me about your recent product development interests?

Kalon Baird, Co-Founder and CTO of Splash Nano

Baird: We’re interested in the research that comes out regarding cannabis minor constituents. We work with other research labs doing two-dimensional chromatography. We’re trying to figure out what compounds exist in the plant that aren’t just the major cannabinoids, and how to work with them in a pharmacological context so that they can be standardized and replicated at scale.

So, it’s not just about making a sugary THC gummy, it’s about seeing what minor cannabinoids, what minor terpenoids and what other unknown compounds can we explore, and then put back into products.

Green: That’s 2D GC-mass spec?

Baird: Yeah, it’s GC-by-GC and tandem mass spec. There are only a couple people that make that piece of equipment. The lab that we work with on that project is called Veda scientific. They’re one of the only people in the cannabis space that uses that machine. And they’re right in our backyard. The tech enables us to further quantify terpene profiles and helps to differentiate our products.

Green: I’d like to focus first on the Splash Nano technology and then we’ll dig into how you got to know each other, and then we’ll finish off with learning more about Happy Chance. So Kalon, tell me more about Splash Nano.

Baird: We employ nano emulsion technology. It’s essentially the science of making oil and water compatible and suspended in a way that reduces droplet size. With nano emulsions, you create an interfacial layer that enhances absorption and solves technical problems like being able to make cannabis oil compatible in water-based matrices, and sometimes in non-water-based matrices. The idea is that as we spread out the particles and as we change attributes of how they’re coated, they’re more bioavailable, and you get a more consistent and faster onset experience like you would in the pharmaceutical or alcohol industry. It’s bringing the industry standard up to the consumer package level and the pharmaceutical level, so that people aren’t waiting the typical hour-long timeframe to absorb that first dose.

Green: Tell me about your business model.

Baird: When we started out in 2018, we were going for a manufacturing license. In the meantime, we saw the drink category evolving and we wanted to be a part of that conversation in that ecosystem. We started developing our own nano emulsions that we knew would be useful when we got our license. We knew that we would sell the base material to co-packers who would put them into beverages. We didn’t want to co-pack the beverages ourselves. So, we developed a drink additive that was our proof of concept that had legs for the technology so that we could show people how to use it. That proof of concept spun off and became its own product and now it’s in the market under the brand name Splash Nano and comes in four distinct product SKUS using minor cannabinoids as differentiators.

The Splash Nano drink additive

Meanwhile, our bread-and-butter business was working with smaller brands, like Happy Chance that needed a path to market but couldn’t get the license or couldn’t go through that whole rigmarole of a two-year waiting period and a half a million dollars and all the other stuff. So, we started taking on all these smaller brands effectively licensing their brand IP and their ideas. In the process, we ended up learning a ton about product development and it became kind of a passion.

We have three core revenue streams. One of them is contract manufacturing, or private labeling. The other one is our own product Splash Nano which is a drink additive. And then the last is we open sourced the technology and sell that as a business-to-business platform so that people can infuse their own products with our fast-acting emulsions. We’re working on a licensing model that will allow other states to create that same consistency, where we send a black box model out to them, and then they infuse the cannabis and then turn that into a product.

Green: Moving on to Katherine here. Tell me about Happy Chance, and how you came up with the brand concept and the product idea.

Knowlton: Going back to what I touched on earlier, many traditional edibles in the space are brownies, cookies and candy type of products that do not contribute to wellness. I wanted to give the wellness driven consumer an option in cannabis. I wanted to create a powerhouse edible that was not only functional and complete but that elevated the consumer’s experience as a whole because of the ingredients we choose and the whole cannabis we source.

Some of the Happy Chance fruit bites

I’m someone who values better-for-you products that contribute to optimal health and well-being. So, I set out to make something. I didn’t really know what I wanted to make in the beginning. I bought a dehydrator and a food processor, and I started messing around with different applications in my kitchen. Over 100 variations later, the fruit bite was born.

The fruit bite is made with dates – a natural sugar that delivers nutritional power: a low glycemic index and high in vitamins, minerals and antioxidants. A sweet you can feel great about. And we use pumpkin seeds which have a lot of great protein. We are working with a company in California that takes imperfect fruits and vegetables and upcycles that back into the food supply chain. We utilize the whole fruits and vegetables as a dried intermediate, capturing all the flavor of nutrients. No added natural flavors and nothing from concentrate.

Green: How does the consistency differ from a gummy?

Knowlton: The consistency is similar to a Lara bar or an Rx bar. Essentially, it’s that same consistency in a bite form and so it’s very different than a gummy. It’s a low dose, low sugar alternative to the modern-day gummy.

Green: So, you’ve got this healthy concept for the fruit bite. You’re looking at suppliers and technologies to infuse the product. How did you finally decide on Splash Nano?

Knowlton: I watched my partner lose his company a few years ago to a larger vertically integrated company. The MSO promised the moon and the stars, and they got lost in the weeds of their eco-system, ultimately losing their company. That said, I was very sensitive when I first started on this journey. I even took on my own partners who didn’t work out either. I spoke with a lot of manufacturers in the selection process. Splash Nano was the tenth manufacturer I spoke with.

It was a very organic way of meeting. I am also based in Santa Barbara where Splash Nano is located. My partner’s brother shared an office space with Kalon, so we met through that connection. I learned right away that Splash was founded on wellness, much like Happy Chance. It was important to source clean cannabis, an aspect that Kalon and his team take pride in. We quickly discovered that Kalon’s Splash Nano technology was going to work in my product. Happy Chance immediately found a home, and it has been an organic evolution of realistic business and friendship.

Green: Kalon, I’d love to get your perspective as well. How do you think about partnering with brands?

Baird: Because of our contract manufacturing experience, we’ve been able to touch approximately 50 brands over our three-year tenure in this space. We’ve seen kind of everything from the multi-state operator to the owner-operator and everything in between. I developed a passion for working with these smaller brands for a lot of different reasons. This industry is built on the success of small mom and pops. Yes, the multi-state operators do have a place and they absolutely add a lot of value. But at the same time, they have their own natural challenges. You have essentially a culture of employees versus a business owner that’s making a lot of their own decisions.

There are advantages to somebody like Katherine, who’s in the trenches of business, and understands the ebbs and flows and ups and downs of this industry and be able to get through some of those challenges a lot more organically and a lot more sustainably. Katherine has such a deep pulse on her business and on her customer and on her own money. She tends to make a lot more calculated decisions, and I really appreciate that.

There’s a lot of waste that gets accumulated in this industry through packaging, through bad decisions, and over extensions of capital. It’s sad to watch and you see these people that have great potential, but it’s kind of lost in this sort of the framework of a large organization. Again, I like multi-state operators, they’re great. There’s nothing wrong with them, but it’s just a different flavor. I’m trying to highlight the fact that working with somebody that has a pulse on her business, and the passion for what she’s doing is wonderful. It’s not just about making money; it’s about adding value.

Green: Katherine, talk to me about sustainability and how you’ve woven that into your product.

Knowlton: We’re dedicated to supporting Product, People and Planet. That’s the whole mission and ethos of Happy Chance. As a chef, I wanted to be intentional about where our ingredients come from. We only source organic and upcycled ingredients – an essential recipe in sustaining a healthy, eco-friendly plant. Intention and integrity are always at the forefront of our products. We prioritize partnering with more transparent supply chains. We want to show the world how cannabis can promote positive lifestyle changes that support living more actively and consciously.

To reiterate, we are also not using anything from concentrate. We are using the entire strawberry, the entire blueberry and so it encapsulates all the flavor and all the nutrition that you would have from a fresh fruit into our products.

Green: How do you think about sustainability in product packaging?

Knowlton: As far as packaging goes in this industry, we’re very limited in what we can do. Compostable packaging isn’t really available, but we have partnered with a packaging company that definitely has mindfulness at the core of their mission. They have established their entire supply chain to ensure they are focusing on green practices and reducing waste each step of the way. Their energy efficient machinery creates a zero-waste manufacturing process to reduce their carbon footprint and they utilize soy and vegan inks to help reduce air pollution by minimizing toxic emissions in the air. My hope for the industry is that as it continues to evolve, we can become less wasteful as far as packaging goes.

Green: Rapid fire questions for both of you: What trends are you following in the industry right now?

Knowlton: As a chef and coming from the CPG world, I’m passionate about health and wellness. I think that it’s important to stay on trend with what we’re seeing in CPG. There’s definitely a market as far as people wanting these better-for-you products. I want to bring that into the cannabis space.

Baird: We’re seeing the inclusion of minor cannabinoids, terpenoids, standardized recipes and faster- or slower-acting delivery systems. So, I’m following trends in advanced drug delivery systems paired with minor cannabinoids.

Green: What are you most interested in learning about?

Knowlton: I’m most interested in how I can take what I’ve learned in the food space and help bring that into the world of cannabis through Happy Chance. Ultimately cannabis is plant medicine. So, how can we educate people that the ingredients we choose to make products should be good for us too. I think that there’s a lot that can be done with it from a from a health and wellness standpoint.

Baird: I’m interested in learning more about the analytical overlay between quantifying and standardizing entheogens and plant medicines like cannabis into the product development process in CPG. I’m thinking of ways to blend the two worlds of traditional science and New Age medicine.

Green: Awesome, that concludes the interview. Thank you both, Katherine and Kalon.

Cannabis Manufacturing Considerations: From Raw Materials to Finished Goods

By David Vaillencourt, Kathleen May
2 Comments

Facility layout and design are important components of overall operations, both in terms of maximizing the effectiveness and efficiency of the process(es) executed in a facility, and in meeting the needs of personnel. Prior to the purchase of an existing building or investing in new construction, the activities and processes that will be conducted in a facility must be mapped out and evaluated to determine the appropriate infrastructure and flow of processes and materials. In cannabis markets where vertical integration is the required business model, multiple product and process flows must be incorporated into the design and construction. Materials of construction and critical utilities are essential considerations if there is the desire to meet Good Manufacturing Practice (GMP) compliance or to process in an ISO certified cleanroom. Regardless of what type of facility is needed or desired, applicable local, federal and international regulations and standards must be reviewed to ensure proper design, construction and operation, as well as to guarantee safety of employees.

Materials of Construction

The materials of construction for interior work surfaces, walls, floors and ceilings should be fabricated of non-porous, smooth and corrosive resistant surfaces that are easily cleanable to prevent harboring of microorganisms and damage from chemical residues. Flooring should also provide wear resistance, stain and chemical resistance for high traffic applications. ISO 22196:2011, Measurement Of Antibacterial Activity On Plastics And Other Non-Porous Surfaces22 provides a method for evaluating the antibacterial activity of antibacterial-treated plastics, and other non-porous, surfaces of products (including intermediate products). Interior and exterior (including the roof) materials of construction should meet the requirements of ASTM E108 -11, Standard Test Methods for Fire Tests of Roof Covering7, UL 790, Standard for Standard Test Methods for Fire Tests of Roof Coverings 8, the International Building Code (IBC) 9, the National Fire Protection Association (NFPA) 11, Occupational Safety and Health Administration (OSHA) and other applicable building and safety standards, particularly when the use, storage, filling, and handling of hazardous materials occurs in the facility. 

Utilities

Critical and non-critical utilities need to be considered in the initial planning phase of a facility build out. Critical utilities are the utilities that when used have the potential to impact product quality. These utilities include water systems, heating, ventilation and air conditioning (HVAC), compressed air and pure steam. Non-critical utilities may not present a direct risk to product quality, but are necessary to support the successful, compliant and safe operations of a facility. These utilities include electrical infrastructure, lighting, fire detection and suppression systems, gas detection and sewage.

  1. Water
Microbial monitoring methods can include frequent/consistent testing

Water quality, both chemical and microbial, is a fundamental and often overlooked critical parameter in the design phase of cannabis operations. Water is used to irrigate plants, for personnel handwashing, potentially as a component in compounding/formulation of finished goods and for cleaning activities. The United States Pharmacopeia (USP) Chapter 1231, Water for Pharmaceutical Purposes 2, provides extensive guidance on the design, operation, and monitoring of water systems. Water quality should be tested and monitored to ensure compliance to microbiological and chemical specifications based on the chosen water type, the intended use of the water, and the environment in which the water is used. Microbial monitoring methods are described in USP Chapter 61, Testing: Microbial Enumeration Tests 3and Chapter 62, Testing: Tests for Specified Microorganisms 4, and chemical monitoring methods are described in USP Chapter 643, Total Organic Carbon 5, and Chapter 645, Water Conductivity 6.Overall water usage must be considered during the facility design phase. In addition to utilizing water for irrigation, cleaning, product processing, and personal hygiene, water is used for heating and cooling of the HVAC system, fogging in pest control procedures and in wastewater treatment procedures  A facility’s water system must be capable of managing the amount of water required for the entire operation. Water usage and drainage must meet environmental protection standards. State and local municipalities may have water usage limits, capture and reuse requirements and regulations regarding runoff and erosion control that must also be considered as part of the water system design.

  1. Lighting

Lighting considerations for a cultivation facility are a balance between energy efficiency and what is optimal for plant growth. The preferred lighting choice has typically been High Intensity Discharge (HID) lighting, which includes metal halide (MH) and high-pressure sodium (HPS) bulbs. However, as of late, light-emitting diodes (LED) systems are gaining popularity due to increased energy saving possibilities and innovative technologies. Adequate lighting is critical for ensuring employees can effectively and safely perform their job functions. Many tasks performed on the production floor or in the laboratory require great attention to detail. Therefore, proper lighting is a significant consideration when designing a facility.

  1. HVAC
urban-gro
Proper lighting is a significant consideration when designing a facility.

Environmental factors, such as temperature, relative humidity (RH), airflow and air quality play a significant role in maintaining and controlling cannabis operations. A facility’s HVAC system has a direct impact on cultivation and manufacturing environments, and HVAC performance may make or break the success of an operation. Sensible heat ratios (SHRs) may be impacted by lighting usage and RH levels may be impacted by the water usage/irrigation schedule in a cultivation facility. Dehumidification considerations as described in the National Cannabis Industry Association (NCIA) Committee Blog: An Introduction to HVACD for Indoor Plant Environments – Why We Should Include a “D” for Dehumidification 26 are critical to support plant growth and vitality, minimize microbial proliferation in the work environment and to sustain product shelf-life/stability. All of these factors must be evaluated when commissioning an HVAC system. HVAC systems with monitoring sensors (temperature, RH and pressure) should be considered. Proper placement of sensors allows for real-time monitoring and a proactive approach to addressing excursions that could negatively impact the work environment.

  1. Compressed Air

Compressed air is another, often overlooked, critical component in cannabis operations. Compressed air may be used for a number of applications, including blowing off and drying work surfaces and bottles/containers prior to filling operations, and providing air for pneumatically controlled valves and cylinders. Common contaminants in compressed air are nonviable particles, water, oil, and viable microorganisms. Contaminants should be controlled with the use appropriate in-line filtration. Compressed air application that could impact final product quality and safety requires routine monitoring and testing. ISO 8573:2010, Compressed Air Specifications 21, separates air quality levels into classes to help differentiate air requirements based on facility type.

  1. Electrical Infrastructure

Facilities should be designed to meet the electrical demands of equipment operation, lighting, and accurate functionality of HVAC systems. Processes and procedures should be designed according to the requirements outlined in the National Electrical Code (NEC) 12, Institute of Electrical and Electronics Engineers (IEEE) 13, National Electrical Safety Code (NESC) 14, International Building Code (IBC) 9, International Energy Conservation Code (IECC) 15 and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ).

  1. Fire Detection and Suppression

“Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs.”Proper fire detection and suppression systems should be installed and maintained per the guidelines of the National Fire Protection Association (NFPA) 11, International Building Code (IBC) 9, International Fire Code (IFC) 10, and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ). Facilities should provide standard symbols to communicate fire safety, emergency and associated hazards information as defined in NFPA 170, Standard for Fire Safety and Emergency Symbols 27.

  1. Gas detection

Processes that utilize flammable gasses and solvents should have a continuous gas detection system as required per the IBC, Chapter 39, Section 3905 9. The gas detection should not be greater than 25 percent of the lower explosive limit/lower flammability limit (LEL/LFL) of the materials. Gas detection systems should be listed and labeled in accordance with UL 864, Standard for Control Units and Accessories for Fire Alarm Systems 16 and/or UL 2017, Standard for General-Purpose Signaling Devices and Systems 17 and UL 2075, Standard for Gas and Vapor Detectors and Sensors 18.

Product and Process Flow

Product and process flow considerations include flow of materials as well as personnel. The classic product and process flow of a facility is unidirectional where raw materials enter on one end and finished goods exit at the other. This design minimizes the risk of commingling unapproved and approved raw materials, components and finished goods. Facility space utilization is optimized by providing a more streamlined, efficient and effective process from batch production to final product release with minimal risk of errors. Additionally, efficient flow reduces safety risks to employees and an overall financial risk to the organization as a result of costly injuries. A continuous flow of raw materials and components ensures that supplies are available when needed and they are assessable with no obstructions that could present a potential safety hazard to employees. Proper training and education of personnel on general safety principles, defined work practices, equipment and controls can help reduce workplace accidents involving the moving, handling, and storing of materials. 

Facilities Management

Facilities management includes the processes and procedures required for the overall maintenance and security of a cannabis operation. Facilities management considerations during the design phase include pest control, preventative maintenance of critical utilities, and security.

Damage from whiteflies, thrips and powdery mildew could be prevented with an appropriate PCP

A Pest Control Program (PCP) ensures that pest and vermin control is carried out to eliminate health risks from pests and vermin, and to maintain the standards of hygiene necessary for the operation. Shipping and receiving areas are common entryways for pests. The type of dock and dock lever used could be a welcome mat or a blockade for rodents, birds, insects, and other vermin. Standard Operating Procedures (SOPs) should define the procedure and responsibility for PCP planning, implementation and monitoring.

Routine preventative maintenance (PM) on critical utilities should be conducted to maintain optimal performance and prevent microbial and/or particulate ingress into the work environment. Scheduled PMs may include filter replacement, leak and velocity testing, cleaning and sanitization, adjustment of airflow, the inspection of the air intake, fans, bearings and belts and the calibration of monitoring sensors.

In most medical cannabis markets, an established Security Program is a requirement as part of the licensing process. ASTM International standards: D8205 Guide for Video Surveillance System 23, D8217 Guide for Access Control System[24], and D8218 Guide for Intrusion Detection System (IDS) 25 provide guidance on how to set up a suitable facility security system and program. Facilities should be equipped with security cameras. The number and location of the security cameras should be based on the size, design and layout of the facility. Additional cameras may be required for larger facilities to ensure all “blind spots” are addressed. The facility security system should be monitored by an alarm system with 24/7 tracking. Retention of surveillance data should be defined in an SOP per the AHJ. Motion detectors, if utilized, should be linked to the alarm system, automatic lighting, and automatic notification reporting. The roof area should be monitored by motion sensors to prevent cut-and-drop intrusion. Daily and annual checks should be conducted on the alarm system to ensure proper operation. Physical barriers such as fencing, locked gates, secure doors, window protection, automatic access systems should be used to prevent unauthorized access to the facility. Security barriers must comply with local security, fire safety and zoning regulations. High security locks should be installed on all doors and gates. Facility access should be controlled via Radio Frequency Identification (RFID) access cards, biometric entry systems, keys, locks or codes. All areas where cannabis raw material or cannabis-derived products are processed or stored should be controlled, locked and access restricted to authorized personnel. These areas should be properly designated “Restricted Area – Authorized Personnel Only”.

Future Expansion

The thought of expansion in the beginning stages of facility design is probably the last thing on the mind of the business owner(s) as they are trying to get the operation up and running, but it is likely the first thing on the mind of investors, if they happen to be involved in the business venture. Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs. Thought must be given to how critical systems and product and process flows may be impacted if future expansion is anticipated. The goal should be to minimize down time while maximizing space and production output. Therefore, proper up-front planning regarding future growth is imperative for the operation to be successful and maintain productivity while navigating through those changes.

Essential Elements to Set Up a Green, Zero-Waste Grow Facility

By Anthony Franciosi
1 Comment
Anthony Franciosi, Honest Marijuana

Clean, ecologically sound production methods are the ideal for any cultivation or farming activity. Taking from the earth only what is needed to grow the crop and leaving behind little in the way of chemicals and land/water loss is the goal; with cannabis grow facilities, it can also be a reality.

This type of production does require some capital investment into state-of-the-art equipment and facilities, with standards that are equal to or even surpass current EPA and USDA regulations. While cannabis growing does not yet have access to the organic certification, that doesn’t mean growers can’t abide by and even go beyond the rules, to grow clean, healthy and environmentally sound cannabis.

There are a few essential elements required to make this kind of operation a reality.

Ecologically advanced use of power

  • For any indoor facility, one of the key elements is lighting. Using as energy efficient a system as possible is key. The best option at the moment is LEC lighting, which provides a spectrum of light that is very close to natural. This makes checking on plant progress more realistic and, with the inclusion of UV-B in the spectrum, can improve yields as well. In addition, the LEC bulbs have a long life—up to 2 years—which means lower maintenance costs as well.
  • The demand for high-quality, organically grown cannabis continues to increase

    Another aspect of growing that tends to use a lot of power is the cooling system. A standard HVAC system will be power intensive, so alternative ones like water chilled climate control systems are just as effective and 30% more power efficient. These systems are also able to reuse wasted power by feeding it back into the system, creating an additional 10% energy reduction. In addition, when the outdoor air temperature dips below 45 degrees, a water chilled system can switch to using the outside air, creating 60—70% in energy savings.

Efficient management of water resources

  • Cultivators depend heavily on water to ensure that the plants are hydrated and able to absorb the nutrients they need to grow and thrive. The result for many however is an excessive waste of water. This is a problem when a grow facility is leveraging municipal water resources. A water meter helps to manage and track usage but to ensure that it is used as efficiently as possible, a “top feeding” method of usage ensures minimal water waste (5% or less).

Effective waste management

  • Wastewater is a byproduct of any water intensive cultivation method but there again, managing the systems to ensure that what water isn’t reused and becomes “gray water” is still as clean as possible is the ideal. A high-quality filtration system keeps sediment, chlorine and other harmful elements out of the water supply — and out of the municipal sewage system. Further, by using organic matter throughout the growing process, the wastewater that is produced will meet every federal standard for organic food production.
  • All plant waste in a grow facility—for example: stems and fan leaves—is disposed of according to state and local laws. With cannabis plants, that requires a certain level of security, including locked dumpsters that are only unlocked and placed outside when the removal trucks arrive on site.

Organic farming practices

  • Using OMRI (Organic Materials Review Institute) listed soil is an essential part of clean, environmentally friendly growing. To ensure the proper nutrients are available for each harvest, once a crop is gathered, the soil is transferred to a local landscape company to compost and reuse.
  • Pesticides need to obviously be avoided and all fertilizers need to be USDA approved as organic and all nutrients need to be certified by OMRI to ensure they don’t contain any synthetic materials.

Considering all of these aspects is essential to creating an ecologically friendly grow facility with tremendous yields that are clean and safe for the end consumer, as well as minimizing the impact to the earth.

Clean Green Farming is Good for Cannabis

At Raw Garden, we have a ‘Farming First’ philosophy because we understand that the process of farming is the process of managing the plant’s life and the management of the land those plants grow on – this is when the plantgets its chance to thrive but requires that it is properly nurtured in order to provide resources such as high-quality terpenes and cannabinoids.

Our cannabis plants are sun-grown in Santa Barbara county soil just like other California crops. From the seed to the shelf, we are vertically integrated and maintain quality control at every step in the process. We grow our own seeds, farm and harvest our own plants, and process our own products while employing sustainable and regenerative farming practices – only organic and natural fertilizers, soil amendments and pest control methods are used on thefarm.

As farmers we have a responsibility to care for the land and the soil to ensure it is fertile and healthy well into the future. We take care of the soil and it takes care of our plants. The result is premium quality products that our customers love and trust. Our success and commitment to quality is proof that the economics of clean, sustainable operations are achievable. We’re farmers and scientists on a mission to make clean, high quality cannabis that is affordable and accessible.

A few of the sustainable agriculture practices we employ at Raw Garden include:

The Clean Green Certified logo

Clean Green Certification – Since our inception, we have been certified and licensed members of Clean Green, the #1 globally-recognized organic and sustainable cannabis certification program. The program was created in 2004 as a way to standardize legal cannabis products and the result was a program to help farms and brands obtain organic-like certification based on the USDA National Organic program. Clean Green-certified growers and processors regularly win awards for their high-quality products, including our award-winning extracts.

Water Conservation – Our farm team waters at the right time of day to reduce evaporative water loss; we also use drip irrigation and mulch to reduce water waste and runoff. Last year, we used about 8,000 gallons of water per acre on average, which is significantly less than standard outdoor grown crops.

Natural Fertilizer and Pest Control – We apply only organic fertilizers and foliar feeds and we spray only organic pathogen-free inoculants to keep our plants healthy and disease-free, which consistently results in high yields. To naturally deter pests, we recruit beneficial predatory insects like ladybugs and parasitic wasps, in addition to botanical oils and diatomaceous earth.

Precision Agriculture (PA) and Site-Specific Crop Management (SSCM) – We utilize technology to manage crops and increase farm efficiency, such as machine learning for fertilizer optimization and digital sensors in the field to monitor crops.

Soil Health and Terroir – Like grapes for wine, cannabis plants grown in the soil have terroir that affects the flower’s qualities, characteristics, terpene profile, aroma and taste, based on temperature, climate, soil composition and topography, as well as other environmental influences. Micro-climates matter – the same strain of cannabis grown along the coast likely has a different taste and potency than one grown inland. We grow in Santa Barbara wine country for the combination of fertile soil, hot sun, and cool nights which yield an incredibly diverse, potent and flavorful crop of cannabis flowers. Between growing seasons, we employ regenerative agriculture by planting cover crops including oat, beans, peas and buckwheat to add nitrogen and organic matter naturally back in the soil. This method of cover crops also helps reduce pests and soil-borne diseases in preparation for the next growing season. We know that an ideal environment in combination with healthy soil and good land management results in healthier, more vigorous plants, which translates to higher-quality products.

As farmers, it is our responsibility to care of the land with good management decisions today so that we grow the best quality products while better preserving the land for the future. It takes careful planning, knowledge of the land, a commitment to sustainable practices and a desire to put farming first.

National Ag Day: An Interview with Industry Leaders Disrupting Agriculture in Positive Ways

By Aaron Green
No Comments

National Agriculture Day (March 23, 2021), is an annual event held by the Agriculture Council of America (ACA), a not-for-profit 501-c (6) organization, to increase the public awareness of agriculture’s vital role in our society.

The ACA believes that every American should:

  • Understand how food and fiber products are produced.
  • Appreciate the role agriculture plays in providing safe, abundant and affordable products.
  • Value the essential role of agriculture in maintaining a strong economy.
  • Acknowledge and consider career opportunities in the agriculture, food and fiber industry.

We investigated how the hemp and cannabis industry is disrupting agriculture in positive ways, from automated trimming, to controlled environment agriculture, to water conservation and beyond. We interviewed Aaron McKellar, CEO and President of Eteros Technologies, parent company of Mobius Trimmer and Triminator, Mark Doherty, Executive Vice President of Operations, urban-gro, Inc. and Derek Smith, Executive Director at Resource Innovation Institute (RII) to get their perspective on agricultural innovation.

Aaron McKellar, CEO and President of Eteros Technologies

Aaron Green: Why is hand-trimming inefficient at scale?

Aaron McKellar: Hand-trimming is inefficient at scale because it is so labor-intensive and time-consuming, not to mention repetitive and frankly boring. It’s hard to stay fully engaged as a worker trimming by hand, so the consistency of your finished product isn’t reliable with a crew of hand-trimmers.

Aaron McKellar, CEO and President of Eteros Technologies

A hand-trimmer can produce good quality trim on about 2 or 3 pounds per day. A scaled-up facility running just one Mobius M108S Trimmer can realize up to 120 pounds per hour, replacing many dozens, or even into the hundreds of hand-trimmers. The HR nightmare this presents, and all the associated costs of paying and facilitating dozens of employees (parking, washrooms, lunchrooms, PPE and gowning, etc) is simply unworkable. And that’s before COVID.

Green: How does automated trimming benefit large producers and how does the quality compare to hand-trimming?

McKellar: Not all automated trimmers are created equal. Any of the machines out there will help to reduce the need for hand-trimmers by taking off the bulk of the leaf, leaving a small team of “hand-polishers” to finish it up. The Mobius Trimmer is the only automated trimmer on the market today that leaves the technology of the original machines in the past and employs next-gen technology to truly mimic hand-trimmed quality with stunning through-put rates.

We have high-end producers using Mobius Trimmers whose own QC department cannot discern Mobius-trimmed flower from hand-trimmed flower. Hand polishing crews tend to be far smaller when using a Mobius vs first-gen machinery, and many Mobius users don’t touch up at all, instead going straight to market right out of the trimmer. For a look at how our technology differs from the rest of the field, check out this look under the hood.

Mark Doherty, Executive Vice President of Operations, urban-gro, Inc.

Aaron Green: What is controlled environment agriculture?

Mark Doherty: Cannabis cultivators understand growing indoors because, prior to legalization, they had been doing it for years in the gray market. It is by way of that experience that cultivators learned how to manipulate a highly-valuable, complex plant in an indoor setting. As cannabis legalization spread across the United States, many government regulators required that it be cultivated indoors according to strict regulatory protocols. Fast forward 10 years, and we have an industry that is keenly aware of the indoor environmental conditions required to be successful. Critical factors like heating, cooling, ventilation, dehumidification, and how to best mimic Mother Nature’s energy through lighting are all deliberately optimized.

Mark Doherty, Executive Vice President of Operations, urban-gro, Inc.

With cannabis cultivation driving the advancements of controlled environment agriculture, market and regulatory forces demanded higher efficiency, reduced energy and resource consumption, and clean crops. In most states, cannabis crops have more stringent testing than food crops. For instance, the lettuce in Massachusetts will not pass the standards for cannabis in Massachusetts. It’s through rapid innovation and technology adoptions that the cannabis industry has paved the way for lettuce to be profitably grown indoors.

Green: How can controlled environment agriculture help alleviate supply chain stresses?

Doherty: By growing food closer to the consumer, you reduce food miles; meaning, that link in the food supply chain gets a lot shorter and is less prone to disruption. Whether you have hyper small cultivation facilities on every street corner, or a larger cultivation facility geographically close to consumers, you can grow 24/7/365. Furthermore, growing locally allows for better prediction of facility output—10 boxes of greens on Monday, 50 boxes of greens on Tuesday, and five boxes of greens on Thursday. This eliminates harvesting a large crop before it is ripe and likely requiring cold storage. The controllability of controlled environment ag is that consistent, reliable contribution to the food supply chain and shortening that path to the consumer.

Derek Smith, Executive Director at Resource Innovation Institute (RII)

Aaron Green: What motivated you to publish the Cannabis H2O: Water Use and Sustainability in Cultivation report?

Derek Smith, Executive Director at Resource Innovation Institute (RII)

Derek Smith: Until this report, if you searched for cannabis water usage, you’d basically find one cited statistic. It was “six gallons per plant per day.” We knew this was from a model based on one extreme illicit market scenario. Based on the data we were seeing and the conversations we were having, this number seemed way off. So, we pulled together a multidisciplinary Water Working Group as part of our Technical Advisory Council. The objective of the Water Working Group was to establish a scientific understanding of how, and how much, water is used for cannabis cultivation so that cultivators have confidence in taking steps to be more efficient, and so that industry leaders, governments and media can be accurately informed about the range of water practices of today’s regulated market.

Green: What key points should cannabis cultivators take away from the report? What key points should regulators and policymakers take away from the report?

Smith: As the cannabis industry matures, water use efficiency will become more important, as it has for other agricultural crops. Pressures to use water efficiently will mount from multiple channels including – reducing input and energy cost, protecting the environment, meeting regulatory standards and simply being good stewards. We recommend that industry and regulators focus efforts on the following areas:

  1. When grown outdoors, water for cannabis production should be assessed like any other agricultural crop and be subject to state and local regulations that apply to other crops. Our research indicates that cannabis neither uses a massive share of water nor uses more water than other agricultural crops. Applying the same standards to cannabis as to other agricultural crops will correctly categorize outdoor grown cannabis as an agricultural crop.
  2. In areas where there may be conflict between water use for cannabis and environmental concerns, regulators and the industry should focus (1) on the timing of water use and (2) the potential of storage to mitigate environmental conflict. Our results show that in many parts of the country legal cannabis farmers have ample water storage to satisfy their needs. In areas where storage is insufficient, increasing storage should be a priority for farmers and regulators.
  3. Our research shows there are still massive differences between cannabis production techniques. As farmers continue to experiment and improve, we expect to see water use be a more important part of cannabis farming decisions and expect new plant varieties and growing techniques to be developed that increase water use efficiency. Yet more data from actual farms and facilities are needed to point the way toward the technologies and techniques that drive optimal efficiency and productivity. It is recommended that producers benchmark their performance and governments consider requiring energy and water reporting by producers. The Cannabis PowerScore can assist in these efforts.
  4. As indoor production continues to grow, especially in areas that have unfavorable climatic conditions for outdoor growing, we expect more cannabis users to rely on municipal water sources. Yet, it is unclear if municipal water suppliers are equipped to work with the cannabis industry. We suggest outreach efforts between the cannabis industry and municipal water suppliers to incentivize efficiency where possible.

The Ten Biggest Mistakes When Building a Cultivation Facility

By Michael Burnstein
3 Comments

As cannabis legalization becomes more prolific across the United States, entrepreneurs are entering the cultivation business in droves. With so many new companies entering the market and growing cannabis, there are a lot of common errors made when getting started. Here are ten of the biggest mistakes you can make when building a cannabis grow facility:

  • Failure to consult with experts in the cannabis business – poor planning in floorplan and layout could create deficient workflow causing extra time and costing profits. Bad gardening procedures may result in crop failure and noncompliance could mean a loss of license. Way too often, people will draft a design and begin construction without taking the time to talk to an expert first. Some important questions to ask yourself and your consultant are: What materials should be used in the building of the grow? Is my bed-to-flower ratio correct? How long will it take before I can see my first harvest? 
  • Contractor selection – DO NOT build your own facility; leave it to the experts. Sure, you have experience building things and you have a friend who has worked in construction. Do not make this mistake – Our experience can save you from the mistake’s others have made. To stay lucrative in this competitive industry and to maximize your products’ quality and yields, have the facility built right the first time. Paying an experienced, qualified cannabis professional to build you a facility will produce better yields and will save you time, stress and money in getting you from start of construction to your first crop.
  • Not maximizing your square footage potential – With today’s fast changing environment, multi-tiered stationary racks, rolling benches and archive style rolling racks help maximize square footage. Without the proper garden layout, you will find yourself pounds short of your potential each harvest.
  • Inadequate power – Not planning or finding out if there is sufficient power available at the site for your current and future needs. This will stop you from building the overall square footage you want. When finding a building make sure you first know how much power you will need for the size grow you want. With proper engineering you will find out what load requirements will be so you can plan accordingly.
  • Material selection – The construction material that goes into a cultivation and extraction facility should consist of nonabsorbent anti-microbial finishes. The days of wood grow benches are long gone. Epoxy flooring, metal studs and other materials are mandatory for a quality-built, long-lasting facility.
  • Hand watering – Once your facility is up and running, many people feel they have spent enough money and they can save by hiring people to water by hand, rather than going with an automated system to handle the watering and nutrients. The problem with this is your employees are not on your plants timetable. What if an employee calls off and can’t come into water at the right time or they mix the wrong amount of nutrients from the formula you have selected? These are issues we see a lot. It is critical to perform precise, scheduled watering and nutrient delivery to increase your yields.
  • Failure to monitor and automate – Automating your grow is important for controlling the light and fertigation schedules as well as data collection and is crucial to maximizing yields. Being able to do this remotely gives you peace of mind in that you can monitor your grow room temperature and humidity at all times and be notified when something is not right.
  • MedicineManTechGrowPoor climate – This can cause stunted growth, smaller harvests and test failures. Our experience has taken us to facilities that have had mold and mildew issue due to poor climate. Proper air balancing, additional dehumidification along with a proper cleaning procedure can get a facility back in working order. Installing proper climate control systems could save millions of dollars.
  • Choosing the wrong site or building – Not knowing the history of the building you are choosing to rent or buy can create logistical and monetary nightmares. The wrong site can be a distribution and marketing disaster. In the wrong building, exponentially more money is spent to bring that building up to the standards needed for successful production and yields. For example, bringing in the ceiling and the cleaning of an existing facility can be a great expense. If you do not know what you are looking at when you purchase, you may be in for months of unaccounted expenses and inaccurate timelines. This can be detrimental for companies and individuals that are on restricted timelines and have to start producing successful and continuous yields from a space that has to be converted into a prime grow facility.
  • Failure to maintain your facility – A dirty site creates an invitation for pests, workplace injuries, unhealthy working environment and equipment failure. Keeping the facility and equipment properly maintained with routine service will ensure efficiency, longevity of equipment life span and reduce mold and bacteria risk. Clean facilities = clean plants and better flower.

CA Health and Safety Warning Laws Have Changed: Are You In Compliance?

By Megan Caldwell, Lindy Martinez
1 Comment

A new California Proposition 65 mandate took effect on January 3, requiring health warning labels for all cannabis products sold in the state. Failure to comply with the requirements can and will result in enforcement against cannabis producers and sellers, resulting in hefty penalties. Here’s what you need to know.

Some Background on Proposition 65 and Cannabis

California’s Proposition 65, also known as the “Safe Drinking Water and Toxic Enforcement Act of 1986,” requires various parties in the supply chain for consumer products to provide warnings on products they sell in the state if exposure to certain chemicals in those products will pose a significant risk of cancer or reproductive harm. Proposition 65 applies to any company that sells products in California, regardless of whether the business is headquartered or manufactures products in California.

This is an example of a Prop 65 warning label. They might look familiar because we tend to see them on a lot of common goods and products.

Cannabis (Marijuana) Smoke” was listed under Proposition 65 in 2009 because of the potential that it contains ingredients or emits chemicals known to cause cancer. These chemicals include toxins such as arsenic, benzene, cadmium, formaldehyde, lead and nickel. In January 2020, Delta-9-Tetrahydrocannabinol (THC) was added to the list of toxic chemicals under Proposition 65 because of THC’s potential to cause reproductive harm. Now, both THC and cannabis smoke are listed under Proposition 65 and require warning labels.

What This Means for You and Your Company

The updated chemical list, which includes THC, became effective January 3, 2021, so the clock to come into compliance is ticking if you are not already complying. Many cannabis companies selling in California already comply with Proposition 65 by including warnings on their products that emit cannabis smoke. However, now companies that have previously issued a consumer warning regarding cannabis smoke must expand their warnings to include both the potential risk of cancer and the potential risk of reproductive harm. Additionally, products that previously did not require a warning for cannabis smoke will now be subject to Proposition 65 for exposure to THC.

The listing of THC implicates a broader range of cannabis products because it affects any product that contains detectable levels of THC, including products that contain less than 0.3% THC in compliance with the 2018 Farm Bill. Under the THC listing, a wide range of cannabis and hemp-derived CBD products, including products that do not emit smoke, such as edibles, topicals and other concentrates are subject to the Proposition 65 labeling requirements.

The agency that oversees Proposition 65 has provided so-called “safe harbor” levels for many listed chemicals that allow companies to forego a warning label if exposure to the chemical occurs at or below a certain threshold. However, no safe harbor level has been established for cannabis smoke or THC, and so the burden falls to the business to determine if the levels of the chemical pose a significant risk to the consumer. This determination typically requires extensive and costly testing that is not practical for most businesses. Thus, parties in the cannabis supply chain should work to properly label all cannabis-related products at this time. Failure to do so is risky. Proposition 65 “bounty hunters” team up with individuals to enforce Proposition 65 by sending notice of violation letters and then often filing lawsuits against businesses they believe are in violation of the statute. Many of these demands and lawsuits settle, as the cost to litigate is expensive. Settling, though, can be expensive, too.

Leaders in Cannabis Formulations: Part 1

By Aaron Green

Natural cannabinoid distillates and isolates are hydrophobic oils and solids, meaning that they do not mix well with water. By formulating these ingredients using various technologies, companies like Caliper and Ripple have learned how to change the solubility properties of the cannabinoids. In addition, formulations can improve bioavailability and onset time of the cannabinoids.

Stillwater Brands is a cannabis formulation company based out of Denver, Colorado, leveraging proprietary technologies for solubilizing cannabinoids in water. Stillwater has a partnership with the Canadian company Green Organic Dutchman and will soon expand their THC line of products, Ripple, into Michigan. Their CBD product line, Caliper, is already sold nationally.

We spoke with Drew Hathaway, senior food scientist at Stillwater, about the Stillwater technology and aspirations for growth. Hathaway joined Stillwater in 2018 after engaging with them as a technical sales representative in his previous role at a food ingredients supplier.

Aaron Green: What trends are you following in the industry?

Drew Hathaway: I can mainly speak to the science side of the business since that’s where I operate, but I do have some insight into the marketing approach and some of the things we look at. We’re looking at traditional food and beverage trends, whether it’s beverage formats, with its unique ingredients that are going to be general flavor trends, which can definitely be very region-specific. One of the things we definitely look at, especially on the THC side, is dosage differences. What are people putting their dosages at? Are they doing a combination of cannabinoids or terpenes? Are they really using individual ingredients? I think that’s something that’s been fairly well established in the THC market, especially since you have the regulatory mandate of 10 milligrams THC being your max single dose.

Drew Hathaway, senior food scientist at Stillwater

When Stillwater first launched in 2016, our company started with lower dose products to provide microdose options. We focus all of our products on functional foods for consumers. It’s why we have three different options for every single one of our products. We have what we call the Pure 10 which is 10 milligrams of THC per serving. We have what we call the Balanced 5. That’s 5 milligrams THC, 5 milligrams of CBD. Then as well as our Ripple Relief, which is a 40 to one ratio of CBD to THC at 20 milligrams CBD and 0.5 milligrams THC. We provide a variety of options for people looking for different dosage levels. We have to look at all of those trends. Packaging trends are also high on our radar.

Aaron: How about flavors?

Drew: We recently launched additional SKUs for our Ripple gummies here in Colorado. We have four different options. We have a sour variety pack that contains sour watermelon, sour apple and sour peach. We also just launched peach cherry, kiwi apple and sour watermelon by itself — and all of those are at the five milligram THC per gummy dose. That aligns with the Pure 10 line as well. We also have been working on some new flavors for the 10 milligram THC quicksticks, which we’re looking to launch early next year. Then, like I mentioned earlier, we’re expanding into Michigan with the THC business, which has been a big goal for us and something that’s gotten a lot of effort behind the scenes.

Aaron: So Drew, how did you get involved at Stillwater?

Drew: I like to describe myself as a traditionally educated food scientist. I went to college and got my bachelor’s and master’s in food science and technology at Ohio State. And then I ended up at a really cool company that was a very large food ingredient supplier. I was technical support to sales for their team. Through that position, I covered the Colorado territory as well as California and I got to cover Stillwater as one of my customers providing technical advice on different products and ingredients that they were looking at. I got involved with Stillwater through that position, back in the early days when they were still trying to develop and figure things out. That would have probably been about four years ago. I was able to see from the sidelines and I was dealing with some other cannabis companies in the space here in Colorado at the time too.

I recognized very early on what they were trying to do by making cannabinoids water soluble and water compatible. It was not only extremely challenging, but also had a ton of potential if they were able to pull it off. At that point, they were still trying to figure out how this is going to work. How do we produce it? How do we sell it? How do we make sure that things are stable? Things of that nature. I got an inside look at Stillwater from the very start, back when there were really only a few people at the company. I would check in with them regularly as they needed help.

I always joked that they were my least important, most interesting customer and I mean that only because they were buying extremely small amounts of ingredients from us. From a sales perspective, naturally, my manager didn’t necessarily want me spending a ton of time working with them. From a personal interest perspective, I was like, “these guys are doing something really intriguing and if they can pull this off this has a ton of potential, so I want to help them however I can.”

I dealt with them in that sales capacity for about two years before they talked about expanding into the CBD space with the Farm Bill passing at the end of 2018. I recognized at that point that I think they had two scientists including Keith, our head of R&D, and I said “alright, that’s really ambitious. You probably need some help! I think it’s time for me to take the leap and see if you guys are interested in having me come on board.” Fortunately, they were and so I’ve been with the company a little over two years now.

Aaron: Can you explain at a high level what the Stillwater products do?

Drew: The base technology behind all of our products for Ripple and Caliper is essentially converting your fat-soluble cannabinoids, whether it’s CBD or THC, into a water compatible product in a process referred to as emulsification. What you’re essentially doing is taking CBD and THC containing oils, whether it’s a distillate or isolate, and you’re essentially breaking those fat droplets into extremely small droplets and then stabilizing them at that size. We make our own emulsion — the fat droplets are extremely small — then when you draw that down into a powder format and redissolve it into water, you are dispersing billions upon millions of fat droplets into your glass. Those droplets are evenly dispersed through the beverage so that you get the same amount of THC or CBD in your first sip that you get in the last sip. That’s really the core technology behind everything that we do.

Taking cannabinoids and making them water soluble is the base technology necessary in order to make something like a shelf-stable infused beverage. There’s no way that you’re going to take traditional distillates or cannabinoids and be able to make a beverage that is shelf-stable otherwise. It’s been really cool since joining Stillwater to learn and understand how that process changes the way that those cannabinoids are absorbed by your body. Emulsification changes things like the onset time, as well as the total amount of cannabinoids your body’s absorbing and using. That’s been something that’s super interesting to see through the clinical research that we’ve done with human participants through Colorado State University.

Aaron: Let’s say if you just take THC oil and put it into an infused product. What’s the difference between that and Ripple?

Drew: Some products formats, such as beverages, just aren’t possible with THC oil without an emulsification technology. As the old saying goes in science, water and oil just don’t mix. So, if you were to take a traditional THC distillate and try to add it to a beverage, that would just float on top as a big oil slick. When you took your first sip, you would essentially get all of the cannabinoids in your first gulp which not only makes precise or partial dosing impossible, but also would taste absolutely terrible. Emulsification makes those infused beverage products possible and stable over a normal one-year shelf life or potentially longer.

Emulsification also changes the way that your body absorbs those cannabinoids, which is something that we’ve definitely put a heavy emphasis on and have really been able to validate with clinical research. I think that’s one of our biggest differentiators versus our competitors. We’re definitely not the only ones in the water-soluble cannabinoid space, but from my understanding, I think we’re one of the few companies that have actually executed human-based clinical trials (vs rodents) through a third-party university and been able to prove that these cannabinoids are detected in your bloodstream as fast as 10 minutes after consumption. We measured those results directly against an oil-based control, where you’re not going to get a peak absorption until maybe 60 to 90 minutes after consumption. What this research found was that not only was our product absorbed much faster, but it also enabled a significantly higher amount of the cannabinoids to actually make it into the participants’ blood stream where it can be used by their bodies. We also found the type of food emulsifier makes a significant difference in absorption – not just emulsion size, counter to common belief.

We use the analogy, “It’s getting a better bang for your buck.” The main purchasing consideration for a lot of edibles consumers when you go to a dispensary is “what is my cost per 10 milligram dose of THC?” That’s one of their key purchasing parameters, especially for your lower budget customer. What’s great with Ripple is one milligram of THC consumed through our Ripple technology is not really equivalent to one milligram of an oil-based product and that your body is actually going to absorb a higher percentage of it. And therefore, you’re going to get more of an effect, whether you’re looking for a medical effect or whether you’re looking for more of a recreational therapeutic effect. It also improves the consistency of that experience. So, with oil-based products, you could have the same products multiple different times and based on what you recently ate, you might get a higher or lower absorption rate or a faster or slower absorption rate. It’s also in the consistency of the experience and I know that from our market research of our consumers of Ripple products here in Colorado since that’s been in the market for a few years now. That’s the number one reason why people really trust our brand is because they can count on getting a consistent experience every time for the same dose.

As we all know, with the THC market and edibles market being newer in general, that’s most people’s biggest fear, especially if you’re a new consumer of THC — you obviously don’t want to consume more than what you can handle as far as getting higher than you want to be or anything like that — So consistency is a really, really key aspect for us and something that I’m definitely proud that we can provide that for our consumers.

Aaron: What does your product look like when you dissolve it into a liquid – let’s say something clear? Is the resulting mixture clear or cloudy?

Drew: We do have liquid concentrates, especially in the Caliper side of things, but with our powders, it kind of billows in as a cloud when you add it to a clear liquid. You can almost think of it like when we pour creamer into coffee: you see the cloud expand and then slowly fill out the cup and then be fully mixed in. Whereas with our products if you pour it into clear water, and you’ll see this white cloud form and then disperse. The final solution is generally a little bit cloudy depending on how much water you add it to.“I’ve been fortunate to be the lead developer for those products for Caliper and for Ripple, and flavor work is definitely something that never gets old.”

Aaron: How are customers using your products?

Drew: For a long time, we’ve had a variety of products in the market, some of which are still in the market, and some of which we’ve pulled since then. The key product for us has always been the Ripple dissolvable powder. It’s an unflavored, unsweetened powder that comes in a little sachet packet that you can tear open just like you would any other product and add to really anything. With its water compatibility, there’s really not a single product that you can’t add it to. It’s been really cool to see through social media, and in general, consumer engagement is electric and is kind of viewed as a novelty. The initial reaction is “Oh, I can take this little powder, put it in my eggs and now I have infused eggs!” It’s been great to see the creativity that our consumers have. We’ve seen it put in such a wide variety of products that literally you can make anything into an edible. I think that’s one of the coolest aspects of that product and why it’s been so successful.

One of the things we did realize pretty fast is that for a lot of people, the convenience and the consistency of the experience was a main driver for why they were purchasing our products. A lot of our real consumers just take that packet apart, ripping it open and pouring it straight in their mouth. It’s the fastest and most convenient way to consume the products, pretty much anywhere. We dug into that with our more recent launch of Ripple Quicksticks. And then we added some flavor, we added a little bit of sugar and sweeteners to make it a consumer-friendly experience where you get a really enjoyable flavor. It’s still just as convenient to consume by just ripping the packet straight open and pouring it in your mouth.

Aaron: It sounds like there must have been some interesting internal product development testing!

Drew: Yeah, definitely. That’s a fun one. I’ve been fortunate to be the lead developer for those products for Caliper and for Ripple, and flavor work is definitely something that never gets old. It can be frustrating at times, it’s definitely not the easiest thing to do. We’ve looked at traditional berry flavors, citrus flavors, as well as weird, kind of out-there flavors, to see what we like and what we think will work with our consumers.

Aaron: What states do you operate in?

Drew: Currently, our Stillwater THC business only operates in Colorado. That’s essentially the genesis of all the companies (Ripple, Caliper) is Stillwater being here in Colorado. We’re excited to announce that we’re expanding to Michigan next year. That’s something that we’ve all been working pretty heavily on developing and getting ready to go. That will be our first expansion of the THC brand to a different state.

We do have a licensing and distribution agreement with The Green Organic Dutchman (TGOD) in Canada. They produce our products using the same technology up there and license also under the Ripple brand name. So, it’s great to see the presence that we’ve been able to expand up there.

Then with Caliper on the CBD side of things with Caliper Ingredients and Caliper Consumer. We operate nationwide for that based on the more recent rules with the 2018 Farm Bill. For me, especially working across all of those business units, it’s really interesting to see the different business approach between your target CBD consumers and your target THC consumers because they’re really different markets. There’s definitely some overlap, but you’re targeting a different demographic to a certain degree. We keep those decisions in mind when we’re choosing how to market and what flavors to use and what products to make. So that’s been really interesting for me to see the behind-the-scenes discussions.

Aaron: I saw on your website, you’ve got consumer options via the dispensaries. Do you work with any infused product manufacturers on a licensing basis or partnership basis?“I’m super excited to continue to see how the medical research will continue to evolve.”

Drew: I’d say the majority of them are definitely on the CBD side for Caliper, partly because the regulatory environment of CBD just is a little bit easier to kind of engage other customers and to sell products across state lines and things of that nature. We do have some partnerships with some of the companies here in Colorado. I’d say the main one that we’ve promoted externally is with Oh Hi infused Seltzers based out of Durango, Colorado. It’s been a great agreement where we provide our base technology via liquid Ripple formulation that they can then infuse into their seltzers. They’ve done a great job with those products and it’s definitely a partnership that’s been mutually beneficial.

Aaron: What are you personally interested in learning more about?

Drew: For me, the whole appeal of joining the industry was research. With prohibition and decades of those restrictions preventing true research there are so many unknown questions that still need to be investigated. I’m super excited to continue to see how the medical research will continue to evolve. I think we’ll get better clarity on the efficacy of individual cannabinoids versus different combinations and ratios of cannabinoids. The entourage effect is something that’s pretty heavily talked about in the industry. I do think there’s some research to support that. I also think there’s still way more unknowns than things that we actually know. So, I’m super interested in seeing how our understanding of everything will continue to improve over time.

I’d love to see the medical research eventually expand into what synergistic benefits exist between cannabinoids and other bioactive ingredients such as turmeric, catechins, antioxidants and other plant-based ingredients that have gotten a lot more interest through the medical research in the last decade.

Then one of the things I’m always excited about being on the science side of things is we’re still investigating the general compatibility of cannabinoids with various types of food and beverage products. That goes not only for ingredient interactions, but also factors like pH, water activity and moisture content. Even packaging definitely plays a role in cannabinoid stability for a variety of products. There’s also a variety of production processing technologies that still need additional investigation, whether you’re talking pasteurization, for beverages, or retort for canned products or newer technologies like high pressure processing (HPP). So, I think the most exciting thing for me, and the reason I was really willing and interested in joining the industry, is there’s so much to learn. I don’t think we’ll ever run out of things to explore. I think as an industry the better we conduct this research, the better off we’ll all be.

Aaron: That’s the end of the interview! Thanks Drew.

NCIA Publishes Environmental Sustainability Recommendations

Earlier this week, the National Cannabis Industry Association (NCIA) published its recommendations for improving environmental sustainability in the cannabis industry. The report, titled Environmental Sustainability in the Cannabis Industry: Impacts, Best Management Practices, and Policy Considerations, was developed by their Policy Council along with experts in the field of environmental sustainability.

The 58-page report is quite comprehensive and covers things like land use, soil health, water, energy, air quality, waste and the negative effects of an unregulated market. While the report goes into great detail on specific environmental policy considerations, like recycling, water usage, energy efficiency and more, it makes a handful of overarching policy recommendations that impact environmental sustainability on a much more macro level.

The report mentions developing a platform for sharing information in the national cannabis industry. The idea here is that information sharing on a national scale for things like energy use can be used as a communication tool for regulators as well as a tool for companies to collaborate and share ideas.

The second more overarching policy recommendation the NCIA makes in this report is “to incorporate environmental best practices and regulatory requirements into existing marijuana licensing and testing processes.” This would help streamline and unify regulations already in place and keeps sustainability in the discussion from the very start.

The last major policy recommendation they make is for incentive programs. They say that governments should incentivize cannabis businesses to operate more sustainably and “prioritize funds provided to businesses where barriers exist to entering the market, such as small- or minority-owned businesses.” The report adds that this could essentially kill two birds with one stone by promoting environmental sustainability and diversity at the same time.

Kaitlin Urso is the lead author of the report and executive project and engagement manager for the Colorado Department of Public Health and Environment. She says that these policy recommendations were designed to benefit everyone. “A successful, socially responsible cannabis industry will require best practices for environmental sustainability. This paper is a vital first step in that effort,” says Urso. “This is important, ongoing work that will benefit everyone. The NCIA’s paper on environmental sustainability is going to inform how we approach important questions related to the future of the cannabis industry.”
