This is Part 2 in The 3-Legged Stool of Successful Grow Operations series. Click here to read Part 1 and stay tuned for Part 3 coming next week.
Aeroponic and hydroponic systems use zero-soil, so water is effectively our media and our transport mechanism for nutrition. Ideally, you start with clean, fresh water with “nothing” in it. Nothing in this case means no heavy metals, pesticides, bacteria or pathogens. There are some scary words in there so let’s talk through the best ways to get to “nothing.”
The first place to start is by testing your source water, whether it is surface, well or municipal water. This will give you an initial idea of how “empty” your water is. Water supplies shift over time, so it is also a very important input to monitor over time with annual or bi-annual testing. Clean water is the essence of success for aeroponics and a great way to lower your cost of production. With proper design and management, you can recycle and reuse 95%+ of the water you draw into your facility.
Reverse Osmosis (RO)
Mothers to clones: Happy clones, it’s all about the water
RO is the most common way to clear your incoming water. The process uses pressure filtration by forcing your water through a series of filters or meshes that block or extract large particles, organics and metals. Normally this is 98%-99% efficient. These systems do require attention and maintenance as they do have filters that are required to be changed regularly depending on the clarity of your original water source and the type of material filtered. This accomplishes a lot of your water clearing process to empty the balloon, but it does not clear the pesky biologicals or pathogens. RO is covered in detail in our “You are what you drink” webinar so look that over for a deeper explanation. There are a wide range of relatively low-cost suppliers based on capacity and filtration efficiency. From an operations standpoint, the key is to understand the filter replacement cycle and cost of replacement.
Ultraviolet Light (UV)
UV light can be used to clear organics and pathogens from water. The primary use is to clear origin water but it is also especially important for recovered water that you save from the humidity in your grow rooms. More on this below. One has to be cautious about the use of UV light. It will cause sunburn and eye damage with exposure so handle this resource with care. After RO & UV treatment, input water should be an empty balloon ready for the addition of your perfect nutrient salt recipe. There are a wide range of low-cost UV lighting solution suppliers from which to choose and they are easy to find.
Dehumidification & Recovery (DEHU)
Early root follicles: Reaching for first nutrients
The number one way to conserve water in an accelerated growth aeroponic grow room is to recapture the humidity that is transpired into the air as the plants grow. While DEHU water is effectively distilled water (or clear of particulates), it can be full of healthy little bacteria or pathogens than may be transported through air or residing in the equipment filters. Clearing these with UV light normally makes this water directly reusable in your fertigation systems. Not all dehumidifiers are perfect. Some metals used in their construction can leach into the recovered water, so this is worth a deeper look as you create your complete water system. Air treatment suppliers are covered in Part 1 of this series.
Used Fertigation Water, or “Flush”
At the start of the flower cycle, take your clean water (the empty balloon) and add your perfect nutrient salt flower recipe and deliver it to your plants. Over the grow cycle from flower to harvest, your plants will use portions of your nutrients and your balloon contents will drift from your target recipe you’re your desired cycle, clear or flush your reservoirs and reset your recipe by refilling your balloon to your exact targets. The exiting nutrient-rich “flush” water can also be recycled into your source water feed since the salts and metals present can be cleared from the mixture through the same RO process that your source water goes through. The end result is perfectly good recycled water savings.
Oxygen Reduction Potential (ORP)
Healthy roots reach for water: Early veg when plants get rolling
ORP is a measurement of an oxidizing agent. Oxidizing solutions are a common and inexpensive method of disinfecting water before and during use in hydroponic systems. Oxidizers can be used to monitor and deal with the “cleanliness” of a nutrient water solution while it is in use. Several oxidizing agents exist with the most common being: hydrogen peroxide, chlorine, ozone and chlorine dioxide. The characteristics of each of these agents and how they interact with the organic matter in solutions is different. The ideal concentrations to use in each situation to kill or control pathogens is unique and one of the topics covered by our “Letters from the AEssenseGrows plant science team” on our website. That deep dive is the subject of another paper.
When you take all of these subjects together and they are done right, you should be able to recycle 95% of your source water with a professional water treatment & recycling system.
Here, I would like highlight the ultimate water hero: Ashley Hubbard, director of cultivation at RAIR Cannabis. For a quick tour of her water treatment and recovery room, see here. No one that I know manages water better than RAIR Cannabis and Ashley leads the team there.
Ideal cannabis profits come from high demand/high selling prices and low production costs. The spread between those two, or margin, can determine the life or death of your business. We want to share this series of articles so that your next investment can be highly successful and high margin out-of-the-box.
Regardless of the grow method (soil, coco, rockwool, hydro or aero), every plant performs best in its own ideal environmental conditions. Experienced growers gained success through hard work, and just that, experience. Many have tried more advanced grow technologies, but shied away due to early trial failures or the complexity of maintaining chemistry across a grow facility. The wonderful thing now is that precision sensors and software controls eliminate the risk to robust healthy plants and harvest success. Growers are now able to both manage production while performing research in line with their operations.
We have learned a great deal working with our grow partners over the last 6 years. Every grow facility and location are different due to local weather, business environment and scale. This series of articles and guide, authored by our expert, Christopher Wrenn, will include recommendations of the most successful approaches we have seen here in North America and all over the world.

Building top-quality cultivation facilities is no simple task. Cultivators are also looking for new help as they shift from older soil or media approaches to more efficient grow methods. One powerful method is aeroponics, which is very good at growing any type of plant in air in a sterile environment, with labor, nutrient and water savings.
Where possible, we will share key vendors that support healthy grow operations and (since it is World Series Time), customer examples that are knocking it out of the park. In today’s competitive business environment, it is critical to do what we can to increase profitability and survival in the face of steep headwinds. We want you to crush it and be “the last man standing.”
So, let’s get to it.
Climate: Environmental Control
We begin with a critical leg in your environment. The process of photosynthesis is more than just light, plant and moisture. We want to do more than just grow plants. We want to grow highly profitable plants. That means we have to accelerate photosynthesis so we are growing faster, bigger and more potent than our competitors.
The Vapor Pressure Deficit (VPD) is the amount of “drying power” available in the air surrounding your plants. This is a useful way to understand the amount of moisture your atmosphere can remove from your plants as they digest carbon dioxide and aspirate water and oxygen into the air around your plants. A higher vapor deficit is a good thing for growth; It is also a measurement of how much nutrient you can uptake into the plant roots and convert into size and potency in the canopy. We recommend that you have resources in your grow rooms to maintain your environment to within 5% of both your humidity and temperature targets for ideal results.
Onyx Agronomics is a Tier 3 indoor cultivator in the State of Washington. This is the canopy in one of their 8 flower rooms.
In our Top Quality Cultivation Facilitywhite paper, we review environmental settings for temperature and humidity for mother, clone/veg and flower rooms for day and night light cycles from early cuttings through to end of harvest flush. Day temperatures can be up to 20% higher than night temperatures for example.
Cooling
Managing temperature may seem straight-forward but the heat generated by LED lights, HPS lights or the sun will vary across rooms, time exposure and with the distance of the light source from the plants. Measurement sensors should be distributed across rooms to monitor and trigger temperature resources.
Humidification/Dehumidification
This is a topic that can be underappreciated by cultivators. It is important to slowly transition humidity as you move plants from cuttings to clones, to veg and to flower. Beginning in a very humid stage to motivate root start, humidity will be stepped down from an opening near 90% down to an arid 50% in your end of flush flower rooms. We detail the transitions in 5% increments in the white paper.
The 4-Layer aeroponic flower room with movable racking systems from the side with a tall human for scale. One can do a lot with 30′ ceilings.
Relative Humidity (RH) and the related VPD are the key metrics to accelerating growth throughout the stages. Not sizing dehumidifiers correctly is one of the most common mistakes our grow partners learn about as they move to full production. In the first phase of turning cuttings from healthy mothers into rooted clones, hitting your target VPD to motivate root growth is the number one success factor. This will require the addition of humidity into your clone room. It is also typical to require raise the humidity of your flower rooms when you transition clone/veg plants from the high humidity clone/veg room into an initially dry flower room, otherwise the plants may go into shock as a result of the dramatic change.
As flowering begins, if humidity remains high, and the VPD is below target, the plants will not be moving nutrients and transpiring moisture. We have seen lowering the humidity from 70% in a flower room down to 50%, results in a yield increase from 50 grams to 90 grams of dry trim bud per plant, so a smooth transition can both accelerate growth and have a big impact on your margins and profitability.
Plants in aeroponics can truly have explosive growth. This means that they will also transpire moisture at an accelerated rate. Fast automated growth in aeroponics means increased humidity output. Sizing these critical systems for humidification/dehumidification are a critical part of the design process.
Airflow
Fans combined with your cooling/heating/humidity/dehu systems need to mix the air in a room to break the boundary layer at the leaf surface for transpiration. As we covered, VPD is critical to growth success. A dry surface motivates the plants to transpire moisture. We recommend flow rates across the canopy in a 0.5-1.5 meter/second rate to align to your genetics and where you are in the flowering process.
A raw facility before it gets outfitted.
Airflow and flowering means rich beautiful aromas are generated. Every facility has to consider odor control. If you are in a populated area, you will have ordinances and neighbors to satisfy. The best way to do this is to minimize the amount of air that exits a facility. This is also the cheapest approach.
Sterile HEPA filters and scrubbing systems clean air of pathogens and odor but they also need to circulate and “condition” air to the correct temperature and humidity levels before it can be recirculated into a room. Oftentimes, this is a good place to also recapture humidity and reinject it into your pure water cleaning systems.
Key vendors to talk to about sizing air treatment systems are SURNA, Quest, Desert Aire and AGS. Each of these vendors have specialties and tend to be superior partners in different regions of the world. We would be happy to introduce you to excellent support resources for air management systems.
Metrc combines a software platform with radio frequency identification technology to track plants and cannabis products from seed to sale. The track-and-trace model quickly became adopted by dozens of states to regulate their cannabis markets over the years, becoming an important standard in the industry.
With government contracts in nineteen states and counting, Metrc has become an omnipresent fixture in the United States cannabis market. States work with Metrc to provide their market’s traceability software for the entire supply chain, which helps prevent diversion to the black market, offers security and safety, aids in recalls and regulatory compliance tools.
We sat down with Michael Johnson, CEO of Metrc, to discuss retail challenges, regulations, cybersecurity, compliance and more.
Aaron Green: What are the major compliance challenges retailers face?
Michael Johnson: Major compliance challenges that retailers face will vary from state to state, however, we do see common themes across state lines. Financial services, for instance, has been a historical industry hurdle, as most big banks and credit card companies deny access to their network, making it difficult for retailers across the board – from bank account setup to limited customer and patient payment options to security issues when managing a cash-only retail business. The tides are starting to change with more credit unions and state-chartered banks opening their doors to the industry, along with new payment technologies for consumers to use instead of cash.
Michael Johnson, CEO of Metrc
We also see common operational challenges, including inventory management issues due to human error, lack of consistent quality assurance, and product theft. Retailers regularly face strict packaging, labeling, and product safety laws along with requirements for public health, storage and sanitation procedures and additional layers of security and surveillance.
Finally, access to compliant and retail-friendly technology systems is important as it can have a major operational impact. If a retailer can choose, selecting the right platform will manage all their operational needs – from ID-scanning at check-in to inventory management to banking – while properly integrating with their state’s track-and-trace technology. That’s a major benefit and one that Flowhub brings to the industry, alongside Metrc.
Aaron: How does compliance for retailers differ from cultivators and manufacturers?
Michael: It is important to note that proactive compliance sits at the center of cannabis regulation. Not only does it ensure the maintenance of license(s) and overall businesses, it helps expand and enhance the industry as a whole. As a highly regulated sector, transparent and consistent compliance initiatives provide the necessary foundation for a safe and secure environment, strengthening all levels of the supply chain and the industry at large.
All industry players must adhere to specific licensing and documentation requirements – an expired or illegal license may lead to serious fines and carries the potential of losing the business. In a handful of states, employees may need a license as well. Real estate also comes into play for all license holders, with special cannabis zoning restrictions, such as requiring distance limits between select institutions.
Since retailers are customer- and/or patient-facing, they may experience unique operational requirements compared to cultivators and manufacturers, including ID-checking policies, customer or patient delivery laws, additional packaging and labeling rules, strict dispensation regulations, in-store and on-shelf product placement, retail signage, and product promotion rules, and more.
Just like retail, cultivation and manufacturing compliance will also vary across states, but with a host of additional compliance requirements to keep in mind – for example, biological, chemical, and physical hazards are something that play a larger role at facility operations, which are subject to Occupational Safety and Health Administration (OSHA) rules. Other compliance issues to highlight on the cultivation and manufacturing side include state requirements on inventory reporting, security patrols, waste removal, and meticulous logging.
Aaron: What is your process for evaluating vendor integrations?
Michael: At Metrc, we maintain an efficient and consistent process for evaluating vendor integrations – an example of our commitment to ensuring the safety and security of legal cannabis markets.
First, integrators petition access into specific instance(s) by filling out a form with their basic information (business name, software name, contact info, etc.), along with any state-required agreements that must be signed. The integrator is then given a set of steps to perform in each instance requested. The steps provided are then evaluated by our API Support team. When all steps are performed accurately, the integrator is added into production and an API key is generated for their use. Licensees must also issue the TPI a User API key to gain access to the API. Overall, the process is a combination of meeting state, Metrc, and licensee requirements.
Aaron: Can you address the cybersecurity landscape METRC faces? What is METRC’s process for dealing with cybersecurity threats?
Michael: Cybersecurity threats are shared across industries and although not unique to Metrc or the cannabis sector, cybersecurity threats and the value of data continues to change. Maintaining strict safeguards around data privacy and the security is a top priority at Metrc and we keep a constant pulse on changes in the cybersecurity landscape, to maintain this safeguard for our customers, industry users, and Metrc as a whole.
Aaron: What trends in cannabis regulation are you following?
Michael: Cannabis rules and regulations are ever evolving, which is why it is vitally important for anyone in the industry to stay up to date. Examples of some we are following closely at Metrc include the SAFE Banking Act, Marijuana Opportunity Reinvestment and Expungement (MORE) Act, and Cannabis Administration Opportunity Act (CAOA); and more generally federal legalization, public health protection, and environmental regulations.
Aaron: What’s next for METRC?
Michael: We continue to expand our customer and user feedback loop to ensure our roadmap meets the unique needs of markets and an overall evolving industry/regulatory landscape. Examples include continued performance improvements, more robust analytics capabilities, user-driven functionality updates, and exploring the design of a more sustainable RFID tag.
The 2022 Emerald Cup Awards will look a little different this year. The competition is adopting a new classification system for different strains of flower, going well beyond the conventional and outdated sativa and indica categories.
Developed by Napro Research in 2013 and supplemented with more than 250,000 terpene tests by SC Laboratories, the PhytoFacts® classification system uses the chemometrics of cultivars to categorize different strains of cannabis, largely based on terpenes, flavor and effects.
The classification system puts different cultivars into six different umbrella categories: Jacks and Hazes; Tropical and Floral; OGs and Gas; Sweets and Dreams; Dessert; and Exotics. “Terpenes, however, with their unfamiliar names and mysterious effects, have mostly added another layer of consumer confusion already complicated by overly broad Indica/Sativa/Hybrid terminology, whimsical strain names, irrelevant THC/CBD percentages, and other ambiguous factors that make the process of selecting the best or correct strain, a less-than-satisfying ordeal for even the most experienced cannabis connoisseurs,” reads the press release.
The names for the six different categories were decided on using current industry-standard terminology, expanded upon with tasting notes, effects common strains, and of course, the primary terpenes. The Emerald Cup believes this will help the industry move forward with a more accurate classification system, revolutionizing how we think about cannabis.
“Together we hope to empower a better way for consumers to understand the range of flavors, aromas and effects within Cannabis, and bridge the gap between what legacy has always known with regards to terpene content defining quality,” says Alec Dixon, co-founder of SC Laboratories. “We need to move away from this fixation that dispensary buyers and consumers have on delta-9 THC, which is currently blurring the lines between craft and corporate cannabis, and is homogenizing cannabis genetics and leading to the loss of biological diversity within Cannabis.”

You generate the product, you should benefit from it too.
If you are not paying for the service, you are the product. This pithy phrase is often heard in discussions about social media’s use of personal information and user-generated content. The idea can be traced back to a 1973 short film that critiques television’s impact on culture and politics. Although about television, the quote, “you are the end product delivered en masse to the advertiser,” still rings true when talking about major online corporations.
We have all seen it with big corporations. In the first three months of 2021, of Facebook’s $26.2B revenue, a whopping $25.4B was from advertising sales. However, the space for an advertisement to be delivered en masse to the public is not the only thing purchased from Facebook. Access to personal information such as your search history, likes and posts are also purchased by companies to determine which advertisements they should target you with.Access to user-generated data by advertisers has sparked privacy and ownership concerns regarding large internet platforms. The idea of being surveilled all the time is uncomfortable, and many large corporations like Facebook have royalty-free and transferable licenses to your posts.
Similarly, many websites in the cannabis industry gain value from information submitted by consumers. As an example, the website Leafly provides over 1.3 million consumer product reviews that are often used for purchasing decisions. These reviews play a role in attracting more people to websites that operate with a similar system to Leafly, and in turn advertising space to reach those people is sold. According to their About page, more than 4.5 million orders for advertising space are placed with businesses on Leafly each year, generating annually about $460 million in gross merchandise value. So, the users work for free to attract an audience to these websites for the advertisers, and the websites make money from advertisers.
Can we empower users with ownership of their content, data and participation in profits?
Frustrated social media users exclaiming “We are the product!” does nothing to change our reality. It is unlikely we will change how big corporations like Facebook work, but can we ensure users receive some of the benefits in our own cannabis industry? Many of these websites, especially those for medicinal cannabis, are designed to genuinely help users. Can we further increase this feeling of having a transaction with the websites rather than feel like we are being sold to advertisers? The world of NFTs may offer some guidance.
An NFT (or non-fungible token) acts as a digital certificate of authenticity. Unlike cryptocurrencies (like Bitcoin), each NFT is unique, so it cannot be exchanged or multiplied. They are kept on a blockchain system, which is a growing list of computationally secure ledgers. The blockchain allows proof of ownership to be established for the person with the NFT, and prevents others from being able to tamper with or claim ownership of the artwork, game, tweet or cat picture it is assigned to. Although non-exchangeable, NFTs can be traded on a digital marketplace, like how a physical piece of art can be auctioned.
While NFTs and cryptocurrencies are certainly not without controversy and flaws, an NFT-like system that provides users with proof of ownership for their data and grants them control over what is done with it may be the way of the future for websites in the cannabis industry. Just like Facebook, when it comes to sales, online display advertisements are some of the top revenue generators for websites in the cannabis industry that utilize user-generated content. With an NFT-like system, users could be granted a royalty for their content, which would obligate websites to give a portion of their profits to the users when their content is sold to an advertiser. Users may be able to have a portfolio of their generated content, have some control over who can access their content and who their personal data can be sold to.
Websites that are more focused on cannabis for medicinal use often pride themselves on being more patient-focused and professional – no pothead puns or crass logos. An NFT-like system might be especially beneficial for these companies, as it would further increase the emphasis of trust and respect for users. In this case, an NFT-like system could be used to assign ownership of reviews to individual website users. Since these reviews attract new people to these websites, when access to a user’s data is sold to advertisement companies, then a portion of that revenue is given to the people who created the reviews. The estimated amount of revenue that reviewers help to bring into the company can be calculated and distributed accordingly. While this may seem like it would cause a significant loss of revenue for the websites, the increased trust that would come with this system would likely promote more users, generating an overall increase in revenue and credibility. Users could become more engaged and spend more time writing reviews, increasing web traffic considerably. Advertisers would be more attracted to the larger audience and the prestige of having their advertisement on a well-respected site.
An NFT-like system could hold large internet corporations accountable.
The new normal is corporations on the internet making money from the content created by users. In return, users receive none of the monetary benefits and have their personal information shared with hundreds of businesses. An NFT-like system, although theoretical, may be able to empower users to hold large corporations accountable for what is done with user-generated data. It is unlikely we can change big companies like Facebook, but if adopted early, this may be plausible in our cannabis industry. This in turn may not only give more ownership to the website users, but could also benefit the websites, and the advertisers. Overall, the product should be the website and the services it provides. An NFT-like system might help promote this and could make users who generate value for the website partners in business.
Vaping is a multi-billion dollar cannabis product category representing more than 20% category share in the US, according to a recent Headset.io report. The 2019 vaping crisis, whereby lung injury and several deaths were caused by the adulteration of vapor pen cartridges with vitamin E acetate, highlighted the importance of safety and emissions testing for vapor pen products. In addition to volatile organic compounds, metals and ceramics contained in the heating elements of cartridges are also a concern. While the FDA has a robust program for emissions testing in nicotine products, they do not currently regulate cannabis. Cannabis vaping is currently regulated at the state level in the United States.
Cannabis vaping is popular among minors owing to its discrete nature. In a recent study published in the Journal of the American Medical Association (JAMA), 14.7% of teens reported vaping cannabis in 2018. In a separate research study, University of Michigan researchers found that teens vaping cannabis were two times more likely to experience respiratory issues than teens who smoked e-cigarettes.
We spoke with Corey Mangold, CEO and founder of PurTec Delivery Systems, to learn more about cannabis vaping safety and their PurGuard technology. Prior to entering the cannabis space, Corey founded a software company in 1998. He also founded the advertising agency Gigasavvy in 2008, which he recently exited from in March 2021.
Aaron Green: How did you get started in the cannabis industry?
Corey Mangold: I got started in the cannabis industry in 2016. My daughter was away at college in San Luis Obispo and got pregnant and was going to have a baby, which obviously I was excited about. I decided to have her come down to Southern California and start a company together, as I’ve done multiple times in my career successfully. I wanted to show her the ropes, and teach her everything from finance to HR, to business development, marketing – everything it takes to be successful – and give her the tools that she would need to be successful for her life.
Green: What kind of things were you into before 2016?
Mangold: I founded my first company in 1998 in the software industry and had that company up until 2005. In 2008 I started another company called Gigasavvy, a nationally recognized advertising agency out of Irvine, California, which I successfully exited in March of 2021.
Corey Mangold, CEO and founder of PurTec Delivery Systems
When deciding to start a company with my daughter, we were interested in the cannabis industry – I think everybody was back in 2016. In 2016, I had started using cannabis again after probably about a 16- or 17-year hiatus. I was using a vape because I had children in the house. I went to literally anywhere I could and bought every type of cartridge on the market. What I found was that their user experience was not like what it was on the nicotine side of vaping. I reached out to associates of mine who had been manufacturing vapes since 2011, starting with the blue e-cigarette, and we engineered a unique device that was proprietary and completely unlike anything on the market. It was incredible, and still to this day, I think it’s probably the best 510 thread cart on the market. We launched that under the Orchid Essentials (CNSX: ORCD, OTC:ORVRF) brand in California and Oregon.
Green: Is that cart something that you sell to other brands as well, or is it purely for the Orchid brand?
Mangold: Yes, purely for the Orchid brand, but it’s what inspired me to start PurTec Delivery Systems. After a few years of struggling in this industry because we didn’t have the access to capital needed – Orchid is a US company traded on the Canadian Stock Exchange (CSE:ORCD, OTC:ORVRF) – and dealing in a substance that’s federally illegal, there was no access to any traditional financing, be it factoring or inventory financing. We were literally creating as much product as we could every month and then selling out almost instantly, and then waiting till the next month to get money in from all our accounts to make more. We had to slug it out. We did get into a little over 500 stores in California and Oregon, but it was just a battle, and I didn’t really want to be touching cannabis.
In 2020, I had a breakthrough in my strategy. I was watching the TV show Gold Rush and I watched one of the guys go and have to buy a new wash plant. He pulls up to this dealer’s yard that sells wash plants and tractors. I saw this dealer had a lot of inventory and clearly a lot of money, and I realized the place to make money was selling the shovels, not really digging for gold. I said to myself if I have the best shovel out there, why am I digging? I should just be innovating new shovels and selling shovels. Hence, I started PurTec Delivery Systems and now for the last year and a half have been 100% focused on developing advanced vaporizer technologies.
Green: Tell me more about PurTec.
Mangold: I founded PurTec with the sole intention of creating safe vaporizers for consumers. We conducted an 18-month safety study in Switzerland with our partners, on vaping devices in the market. I learned a lot of things that I already knew but wanted to see it proven by independent laboratories and by PhDs and MDs, and really see what was so concerning to me. For the last year and a half, we have sought to develop a safe line of vaporizers. I’m very cognizant about what’s going on in my body and want to know what’s going on internally with these products. I don’t think anyone would be using them if they knew what was really going into their lungs.
Green: What are some of the things that consumers should be thinking about when it comes to vape safety?
Mangold: Consumers should be thinking about all the different aspects from inhaling vaporized heavy metals to ceramics. Ceramic particle inhalation is one of my biggest concerns. I think it’s been ignored. I think all the manufacturers know about it and I think it’s been swept under the rug. I think it’s one of the threats that we have. There should be regulatory bodies that are out there protecting consumers like the FDA, hence why I believe federal legalization is so important, because if the FDA was involved not even one of these products would be on the market because the first thing the FDA would do would be very extensive emissions testing to find out what compounds and potential toxins are entering into your body.
Green: There’s clearly a need for safety and regulation in the space, but from where you’re sitting, is there a demand? When consumers go into a store, one of their main focuses is: what’s the THC content? How do you see consumer demand for safety and how do you think about building that awareness?
Mangold: I don’t think there is consumer demand yet. The consumer demand right now is for getting medicated and having fun or getting whatever relief or primary reason you use cannabis. I can point to a direct correlation with the opioid epidemic. No one knew they were as horrible as they are, and doctors were prescribing them left and right, and everyone thought it was okay. People think these cannabis products are okay because they’re on the shelf in every licensed dispensary, and the California Department of Health and the Department of Health in every other state and country has been involved to some degree. So, consumers think that they’re safe. The problem is they’re likely not just like we weren’t with opioids.
I don’t think the consumer demand will be there for quite some time until we start seeing a lot of long-term health impacts where we start seeing people getting lung disease, we start seeing people getting iron lung, different potential brain issues from inhaling adhesives and heavy metals. I think once the health impacts are seen clinically – just like we saw with the opioid crisis – once that was really in the forefront, everybody saw with their own eyes, and then they were aware that there was a problem. So, I think that it’s important to become aware of the potential health impacts, but I think it will take quite some time before that happens.
Green: It sounds to me like you want to get ahead of the industry on this because if it does go federally legal, there will be more stringent requirements. How do you think about that from a product design and development perspective to get ahead of a problem that exists but isn’t reflected in current regulations?
Mangold: The best thing we can do right now in the cannabis vape industry is to look at what the nicotine vape industry is doing. It is controlled by the FDA and there are standards for vaporizers in other parts of the world that are very stringent, like the AFNOR standards, which are in the European Union regulations for vaporizer safety.
What we do is we find the most stringent standards in the world, and we test our products to those standards. If the standards get stricter, we can develop our products and re-engineer them to meet those new requirements. Right now, all our products are emissions tested at AFNOR standards and over-engineered even for those standards. We also are constantly working on reduction of potentially hazardous materials: reductions of heavy metals; only using proven safe and effective materials and FDA approved materials like SAE 316L surgical stainless steel; and using improved ceramics that are not as brittle as the ceramics being used by almost every single manufacturer out there. There’s a lot of things that can be done. It takes supply chain management, understanding the technology and having strong solid teams of scientists and doctors that know this stuff much better than anyone else in the industry does, and leveraging their expertise.
Green: You recently launched a safety feature for minors. Can you tell me more about that?
Mangold: Yes. Two weeks ago, we launched a new software application called PurGuard. PurGuard is a massive innovation and is the first of its kind that we’re aware of. It’s a piece of software that pairs with any device, whether it’s a disposable pod system or a 510 cartridge. You then pair it to your phone and take a picture of your government ID. Then the camera looks at your face, runs quick facial recognition and runs an age check through the largest age-checking platform API in the world. Then based on location and legal age of the user’s location – some states are 18 and different countries have different rules – it validates your ability in your market to be consuming that product. This technology works in 180 different countries.
Once that occurs and the device is ready for you to use, we have another feature that we’ve developed. There is an auto-lock feature that we have where if you’re a parent, like me, and you have kids in the house, you can turn your device to auto-lock right from your phone. When you walk away from your phone and are 10 feet away, your Bluetooth connection will break, and it will automatically lock the device and so your child can’t walk into your bedroom and take your device.
This technology is important to us. Consuming cannabis is horrible for the health of minors. There are serious mental effects on brain growth that occur from using cannabis at a young age because the brain is still developing up until about the age of 23 to 25. So, it’s not safe for them to be using. Of course, I’m sure we all smoked when we were in high school, but the ease of use of vape and the discretion, I think allows minors to use significantly more cannabis than previous generations did 20, 30, 40 years ago. It’s a massive problem right now and I think it’s just a matter of time before the FDA requires such protections. This industry can only survive if we protect minors. So, we’re getting ahead of the curve and setting the standard.
Green: What kind of hardware does PurGuard work with?
Mangold: PurGuard works with every single type of device that we manufacture: 510 thread cartridges, disposables, and pods. If it’s a 510-thread cartridge, the battery has to be a PurTec battery, and the cartridge has to be a PurTec cartridge. They communicate to each other through certain technologies, and it can even recognize what oils are in the cartridge or the pod or the disposable. Moreover, we can tell what strain it is, when it was manufactured, what the potency levels are and more. It records all the usage statistics. We’ve also proven with our hardware, the actual milligram contents being consumed per hit, or draw based on volume, and draw duration. We can track and report to people and say, “Hey, you’re consuming 100 milligrams of THC a day, that’s too high, you need to slow down and maybe go down to 50 milligrams a day.” That will be what is required as it is being required in the nicotine industry under the FDA pre-market tobacco applications (PMTA). When the FDA comes into cannabis, they’re going to want to see the same thing. They’re going to want to know that cannabis products are not promoting people to use more, and they are trying to get people to use less. It doesn’t mean stop using it, but use it in moderation, like everything in life. You shouldn’t be drinking a bottle of whiskey a day. You probably shouldn’t be smoking a pound of weed a day either. Everything in life is moderation and this application not only protects minors but also teaches us about our consumption habits.
Green: A theme here is “skating where the puck is going to be.” What kind of trends are you looking at right now in the industry?
Mangold: The biggest trend I see right now in the industry is disposables. We’ve seen that the trends in cannabis consumption trail behind the nicotine industry by 2-4 years. We see a lot of our customers and potential customers shifting into disposables and are now seeing a very large spike in sales of disposables. I think that’s a big trend, but with that comes another major issue: we now have lithium-ion batteries being thrown away at astonishing rates and going into landfills. PurTec has an answer for that that we’ll be launching here in the next four to six months That will be I think the biggest innovation in regards to eco-friendliness within the vape industry. That’s where I see things going right now.
Green: What are you most interested in learning about?
Mangold: The thing that interests me most, and what I’m most interested in learning about is regulations. Not the regulations themselves, but how regulations are drafted. I’ve sat in several meetings with rules committees for different regulatory bodies throughout the United States and it is laughable. I was recently in a state I’m not going to mention. I asked them what scientists and what doctors they have consulted with and they said none. I just found that dumbfounding. The state regulatory bodies are making decisions without doing due diligence and without bringing in subject matter experts in some cases.
I’m very interested in learning about how we can change our regulatory bodies. Taxpayers pay these salaries and their job at the end of the day is to protect consumers. I think that these cannabis regulatory bodies need to be way more involved with their state’s Department of Health, as well as with the FDA, and National Institute of Health and looking at this as a holistic approach. How do we protect consumers? This is a drug. It’s like anything else out there. If you’re selling tomatoes that were sprayed with a certain pesticide, you must do the research and you have to know what’s in that product before you start putting it in people’s hands. Otherwise, you may have people dying left and right. So, I’m very interested in learning more about regulatory bodies and how they need to evolve and hopefully I can help push them into evolving sooner rather than later.
Green: Great, that concludes the interview, Corey.
Change control, when it comes to quality management systems in manufacturing, processing and producing products such as cannabis edibles or vape pens, is a process where changes to a product or production line are introduced in a controlled and coordinated manner. The purpose of change control process management is to reduce the possibility of unneeded changes disrupting a system, introducing errors or increasing costs unnecessarily.
ASTM International, the international standards development organization, is developing a new standard guide that will cover change control process management for the cannabis and hemp market. The guide is being developed through the D37 cannabis committee.
The WK77590 guide will establish a standardized method for change control process management for cannabis companies so that they can document and track important decisions in manufacturing and quality systems.
For example, an edibles manufacturer would utilize change control process management if they want to use a different type of processing equipment or introduce a new shape or design of their product. Without change control process management, that edibles producer might switch to a new piece of processing equipment without knowing that it requires more energy or uses different raw materials, thus making production unexpectedly more expensive.
While that’s a very cursory example, the premise is simple: Before you undergo a change to your process, plan it out, analyze it, review it, test it out, implement it and make sure it works.
Change control process management can often be summarized in six steps:
Change control is designed to coordinate changes to manufacturing so they don’t disrupt a process.
Plan/Scope
Assess/Analyze
Review/Approval
Build/Test
Implement
Close
Maribel Colón, quality assurance consultant and vice chair of the ASTM subcommittee on cannabis quality management systems, says producers and testing labs will benefit the most from the guide. “As the cannabis industry grows, the quality, expectations, and control challenges grow within,” says Colón. “The creation and implementation of this standard guide will increase cannabis business efficiency and minimize risk, time, and potential cost of poorly managed changes.”
According to a press release, ASTM International is open to collaboration on this as well. Specifically, they are looking for professionals with change control who might be interested in helping advance and develop this guide.
As an experiential marketer that works with a lot of vice-oriented brands, I’ve always been fascinated by the story of the rise of spirits in the US – a history marked by ingenuity in the face of heavy restrictions, clashing social norms, crime and political ideals. Since then, those same qualities have emerged in the story of cannabis and how, against all odds, it has recently begun to push its way into the mainstream. But on the path to legalization, cannabis can also learn a lot from the spirits industry about what not to do.
For example, when laws governing the spirits industry were written in the post-Prohibition 1930s, the federal government wanted to create an equitable landscape. So, they created a 3-tier system – manufacturers or importers must sell to wholesalers, wholesalers must then sell to retailers and retailers sell to us. They figured that keeping manufacturing interests separate from wholesale and retail interests would keep any large company from owning an entire supply chain, muscling out smaller competitors.
In theory, it’s not a bad idea. Imagine the consequences of massive companies like Diageo or AB InBev using their money to pay bars and liquor stores to only stock their brands and not competitors. Add on the Tied House Laws, which basically says an entity in one of the three categories cannot have an ownership stake in any of the others, and you get a seemingly even-handed marketplace.
Tied House Laws theoretically limit one entity from monopolizing a supply chain
In truth, it makes it almost impossible to be disruptive or for new brands to break through. Other industries have innovated by cutting out the middleman and selling direct-to-consumer – something that simply cannot happen in alcohol (minus the wineries and distilleries that can sell direct out of their tasting rooms). Also, now distributors are so consolidated that there are only one or two big distribution companies in each state. So, as a company trying to bring a new product to market, you have to get into one of these highly selective and competitive distributors if you are going to be successful – a challenging ask for a small, independent brand.
Protection racket
Now, imagine that same challenge coming to the cannabis space. With legalization around the corner, the adult use (as opposed to medical use) cannabis industry could easily look like alcohol in the rules that will be set up.
The demand for high quality cannabis continues to increase, but the prices need to level out to stave off the black market.
Right now, adult use manufacturers can sell their products to dispensaries directly. Some use a distributor, but there is no nationwide mandate to – which is probably for the best. If a distributor isn’t a requirement, it forces brands to offer something new to differentiate themselves. It will spark innovation, rather than add an extra profit margin that will get rolled into the final price – a price that is already higher than it should be due to the murky federal legal status. Adding complexity and cost will only make it harder to compete with the illicit market. For the industry to grow, costs for illicit cannabis can’t be lower than its legal counterpart.
Of course, we are in the nascent stages of legalization here and we’ve come a long way culturally and technologically since the 30s. But remember, the rules governing alcohol were written nearly 100 years ago along with the passage of the 21st amendment repealing prohibition. Startlingly, those laws haven’t changed that much since they were written, so any mistakes made now in dealing with the cannabis industry could last for a long time.
A new way forward
What the cannabis industry needs is a new model for the adult use/recreational space, keeping some of what exists in the alcohol industry but without ever mandating use of a distributor – the middle tier. This would mean keeping Tied House Laws in place and applying them to cannabis so that a manufacturer could never hold an interest in a retailer, while still allowing them to sell directly to dispensaries and to consumers. Currently, some states allow for vertical integration, which would change under Tied House Laws.
This should be pretty simple, since most states are already separating licenses by type of activity (manufacturer, retailer, etc.) and it would promote competition while bringing the widest array of products possible to each consumer. Also, it would prevent any behemoths from squeezing out the up and comers.
Constant innovation is a hallmark of the cannabis market and a key factor in continuous growth.
Of course, some retail license allowances could be considered on a case-by-case basis. For example, I would carve out an exception that growers/manufacturers could sell direct to consumers through a single “tasting room” at their brand home. This is similar to the operations of microbreweries, distilleries and wineries. It would encourage education for consumers, and provide great opportunities for brands to show why their products are better or unique.
Given the technology and logistics solutions available to businesses in a 21st century economy, mandated distributors create a sometimes-unnecessary barrier to an already efficient supply chain. If mandated, prices will inflate to cover added margin, thus making it harder to bring consumers over from the legacy market to the legal one. I’m not against the idea of a distributor – they can add tremendous value, but the mandate would seriously curtail industry growth.
Direct-to-retail and direct-to-consumer sales are necessary for the economic health and growth of the industry. Without this, using alcohol as a cautionary tale, at some point the middle tier cannabis brands will inevitably begin to wield an outsized amount of power. We are living at a time where innovation is going to be the key to explosive growth in the cannabis industry, so it’s important to do everything possible to let the market find its way without falling into a century-old trap.
No business is perfect, especially when humans are part of the equation. But, how do you tackle fixing quality issues as they arise? The goal of this article is to shed some light on the value of a CAPA program and why many states are making them mandatory for cannabis businesses.
Let’s consider the following situations:
Analytical lab results for a production batch test above the limit for a banned pesticide or microbial contamination
You open a case of tincture bottles and some are broken
A customer returns a vape pen because it is leaking or ‘just doesn’t work’
Do you…
Document the issue?
Perform some sort of an investigation, asking questions of the people involved?
Ask for a retest? Then, if the test comes back positive, move on?
Let’s go through each one of these and understand why the suboptimal answer could be costing your business money:
You don’t document the issue
I hear excuses for skipping on documentation all the time.
“It’s not a big deal”
“It was a one off”
“The glasses probably broke in transit”
“They are cheap and easily replaceable”
“It’s not worth the time”
Tracking and documenting supplier shipments can help you identify supply chain issues.
In the situation of a couple of broken bottles in a shipment, what if it was the seventh time in the last two months? If you haven’t been documenting and tracking the issue, you have no way of knowing if it was a single occurrence. Remember when you were surprised that your filling team did not have enough bottles? Those broken bottles add up. Without documenting the incident, you will never know if it was truly a one-time mistake or the sign of a deeper issue. The reality is, it could be sloppy handling on the production line, issues with the shipper or even a sign of poor quality coming from the supplier.
Have you ever compared the number of fills vs the number of bottles ordered? How much money have you already lost due to those broken bottles adding up? Do you have the ability to answer this question?
You perform an investigation
Let’s say a customer returns a leaky vape pen. You perform an investigation by asking the production workers what they think went wrong. They say that it’s very difficult to get the seal for the cartridge into place. Their supervisor tells them to try harder, refunds the customer and moves on. But, why is it difficult to get the seal into place? Is it a design flaw? Should a special tool be used to assemble the cartridge properly? Without getting to the root cause of why the seals are leading to leaking cartridges, you are doomed to have repeat issues. Numerous studies have found that less than one in twenty dissatisfied customers will complain, and that approximately one in ten will simply leave for another brand or provider. How much is this unresolved issue truly costing your business?
Asking for a retest and if it passes, releasing the product and moving on.
In Colorado, 15% of the final tested cannabis flower products continue to fail.
Suppose a major producer of cereal received test results for its most popular cereal that were positive for levels of heavy metals that research has shown to be linked to cancer or developmental issues in children. Now, suppose the company stated that it was an isolated incident and a retest showed that the product met acceptable limits. Further investigation showed no paperwork, save for a couple of emails and a phone call between the lab and the producer. Would that give you peace of mind? This is known as “testing into compliance” and was the subject of a landmark lawsuit in 1993 that Barr Laboratories lost.
For many the answer would be a hard NO. But this happens every day. In Colorado, 12.5% of cannabis batches failed final product testing in 2018 and 2019. That’s one in eight batches! What happened to those products? Good question.
Enter: CAPA (Corrective Action and Preventive Action) programs! For people with a background in quality and GMPs (Good Manufacturing Practices), CAPA is a household name. And, it’s quickly becoming a requirement that cannabis regulatory bodies are looking at. Colorado was the first state to explicitly require CAPA programs for all license holders effective January of this year and has provided a free resource for them. But, for the large majority of people, including those in the cannabis industry, it’s just another acronym.
What does a CAPA program do?
The benefits are numerous but two major ones are:
An effective tool for investigating the true root cause
First of all, a CAPA program provides the framework for a tool for investigation – as Murphy’s Law posits – things go wrong all of the time. Whether you have a manual, labor-intensive process or a highly automated operation, the equipment is programmed, maintained and monitored by humans. The logical sequence of problem solving within a CAPA program allows you to thoroughly investigate and determine the root cause of the issue. With a complete understanding of root cause, you are then able to eliminate it and prevent future occurrences – not just in the one area investigated, but in all similar situations throughout the company.
System for continuous improvement
Gathering info from a customer complaint like batch or product IDs can be crucial in a CAPA system
Anyone who is in the market for a new car lately can appreciate the technological advances. In the 1980s, it was air bags and ABS brakes (those of you that drive in snowy climates and remember having to pump your brakes can appreciate technological advancements). Bluetooth technology for hands-free communication and radio control is another example of continuous improvement in cars.
This is one of the biggest predictors and differentiators between profitable and successful companies with satisfied clients and one that is barely scraping by. The cost of poor quality adds up!
Key inputs in a CAPA system
If the output is an improved system and lower cost of quality, we need to make sure we’re considering the potential inputs.
Information that feeds into your CAPA system:
Customer complaints
Every complaint must be recorded. Gather as much information as possible, but at a minimum: the product type/SKU, the customer name and date of purchase. If possible, the batch or product ID.
This is not necessarily to identify products for a recall, but to prevent…
Laboratory test results
This should not be restricted to final product testing, but include any in-process inspections. Say you have a product repeatedly failing final testing, what if it’s actually been consistently failing or very close to failing at the very first in-process inspection? It’s also important to work with your laboratory to understand their method validation process, including the accuracy, precision, robustness, etc.
Most people consider “environmental controls” to be things like temperature and humidity control. While that is true, it can also include pest and contamination control. Poorly designed infrastructure layouts are major contributors to product cross contamination as well.
Supplier information
Undetected supply chain issues (remember the broken bottles?) can add up fast! CAPAs for suppliers cannot just include supplier monitoring, but improvement in how you communicate your needs to your suppliers. It’s easy to overlook non-cannabis raw materials as sources of microbiological and chemical contamination. Conduct a risk assessment based on the type of contact with your product and the types of contamination possible and adjust your supplier qualification program accordingly.
Are you ready to recognize the benefits of a CAPA program?
One more major benefit of CAPA programs to mention before we go is … Preventive via predictive analytics.
In Colorado, 15% of the final tested cannabis flower products continue to fail, mostly due to mold and mildew. A quality system, with effective data capture that is funneled into a CAPA program can easily reduce this by 75%. For even a small business doing $2M per year in revenue, that equates to a revenue increase of nearly $200,000 with no additional expenses.
Whether you are operating in the State of Colorado or elsewhere, a CAPA and Recall program will provide immense value. In the best case, it will uncover systemic issues; worst case, it forces you to fix mild errors. What are you waiting for?
In this “Flower-Side Chats” series of articles, Green interviews integrated cannabis companies and flower brands that are bringing unique business models to the industry. Particular attention is focused on how these businesses integrate innovative practices in order to navigate a rapidly changing landscape of regulatory, supply chain and consumer demand.
Large-scale agricultural practices can take a toll on soil health leading to inefficiencies over the long term. Harvey’s All Naturals is a Colorado-based company specializing in premium farm-to-table full spectrum CBD products. Harvey’s gets all of its hemp from Boot Ranch Farms, an off-grid sustainable hemp farm in Southern Colorado supplied by an artesian well.
We spoke with Harvey Craig, CEO Harvey’s All Naturals and co-founder of Boot Ranch Farms, to learn more about the benefits of regenerative agriculture, how he thinks about soil health, and how they produce their CBD products. Harvey started Boot Ranch Farms in 2014 after the passing of the Farm Bill and Harvey’s All Naturals followed shortly thereafter.
Aaron Green: How did you get involved in the cannabis and hemp industry?
Harvey Craig: I got involved at a very young age, as the youngest of eight kids, seven of which are boys, I was introduced to cannabis on the marijuana side first. As an engineer through the years, I’ve always been involved in creating very efficient growing systems for cannabis.
Harvey Craig, CEO Harvey’s All Naturals and co-founder of Boot Ranch Farms
In the early 2000s, I learned about CBD a little bit through experimenting with marijuana strains to help a friend who had Parkinson’s and also through the research performed by Raphael Mechoulem, an organic chemist and professor at the Hebrew University of Jerusalem in Israel. In 2014, when the Farm Bill made hemp legal, I dropped everything and went into it because I felt “this is what I need to be doing.”
Green: What is sustainable farming mean to you?
Craig: Sustainable farming to me means putting soil health and responsible natural growing practices at the forefront of all agriculture – regenerative processes for soil, in a nutshell. To me, soil health is one of the biggest problems in the United States right now. By regenerating and making our soils living, healthy and with a rich nutrient base we create an ecosystem that is good for human health and health all around.
Green: What do you mean specifically when you say, “soil health?”
Craig: Soil is living. A good natural soil has a living microbiotic structure inside it. There’s a living habitat that forms inside our soil over the years. Large scale agriculture in many cases has depleted or killed this living structure through readily accessible fertilizers and tilling practices.
Farmers understand the soil. There are practices we can undertake that are helping our living soils and helping the microbiotic habitat to thrive. Practices such as no-till technologies, rotating crops, using cover crops, not being a monocrop, responsible water use, healthy fertilizer and pesticide technologies, minimal processing, the list goes on and on…
When we talk about this thing called sustainability, I think it’s very important that we understand there are two sides of cannabis. There’s the marijuana and then there’s the hemp. We can’t put those two together – they’re governed very differently. Hemp became legal through the Farm Bill and is governed by the Department of Agriculture. Hemp is just like any other crop out there really. That means we can mix hemp in with other crops. It’s very much like corn and other crops in how it’s grown on a large scale, industrial basis.
Marijuana on the other hand is governed by each state’s regulatory commission. Those regulations make it very hard to mix in with general agriculture. So, when it comes to the marijuana side, unfortunately, it must be a monocrop. Most marijuana is grown in pots and pots are fine. However, if you are just growing in a pot and then throwing your soil away, that is not very sustainable. As it sits right now, in the marijuana industry there is really no sustainability, unfortunately. The energy use for the lights in indoor grows, for example, creates a huge carbon footprint and load on the electrical grid. I’m not trying to put indoor growing down, but that’s the way it is. The only way I foresee sustainability in the marijuana side of cannabis is to let loose a little bit on regulation and allow it to become a part of normal agricultural processes.
Green: What is it about tilling that degrades the soil quality?
Craig: When we till our soil, we’re turning the organisms in the soil up and we’re allowing the sun to dry them out. If it’s not done properly, you kill that soil structure.
Now, these little microorganisms in our soil create a healthy soil, but it doesn’t happen instantly, this takes years to create. Nobody has the time anymore, everybody’s “go go go” and “make it happen instantly”. So that gets destroyed. Now we have all these dead soils that everybody’s growing in and growers turn to factory-produced fertilizers with readily available nutrients.
When we are talking about cannabis, we can’t just look at monocropping. If you grow one crop in the same soil over and over, the soil is going to get depleted. One of the main things that we deplete is nitrogen and growing other crops, such as clover, can replenish that nitrogen. Growing cover crops protects the soil from the sun, creates nitrogen for the soil, and holds the water within the soil.
Instead of tilling, you can rotate with crops like root vegetables, radishes and other things that have deep root structures. Instead of tearing them up, just let them degrade organically and go back into the soil. Those deep root structures will also help aerate the soil.
Green: What is a farmer’s first approach?
Craig: Farmers want their land to be healthy. True farmers have a oneness with the earth and understand the earth. The farmer’s first approach keeps the farmer involved in creating new technologies for agriculture.
Green: Let’s say you’re a farmer that has land or recently acquired land that’s been industrially grown upon. How would you take that land and start fresh with a regenerative process?
Craig: The first thing you have to do is take soil samples and send them to a lab. That’ll tell you what you’re working with. Also, knowing a little history about the land helps as well. Was it used for grazing? Was it used for growing corn? What was it used for? Were organic practices used?
Then, there are many things you can do to start to regenerate your soil, but it takes time. In many situations, people don’t want to take that time. But what we’re learning is, the people and the farmers that do take that time often take a hit monetarily for the first two or three years. After that, once that structure is maintained, the natural health of the soil can be replenished. Crops will grow better, and they won’t spend as much money on fertilizers and pesticides in the long run because the microbiotic structure in the soil is creating a healthy ecosystem. When we destroy that ecosystem, it doesn’t come back easily or quickly. If there’s a little bit there, it can be regenerated with the right practices.
Green: I understand that the Boot Ranch is an off-the-grid farm. What was your motivation for either going off-grid or remaining off-grid?
Craig: I have a background in alternative energies and engineering, and when creating Boot Ranch Farms there was a lot that went into the sustainability side of it. The farm is extremely far away from the power grid for starters. So, an investment in solar for electricity was money well spent. My thought process was, why would I invest in bringing the wires in when I could actually save money and resources by creating a very efficient solar system and not be tied to the grid? Our farm is self-sustaining without being connected to any grid, which is one of the main reasons for remaining off-grid.
Green: I understand the farm is supplied by an artesian well. How do you monitor your water quality?
Craig: Well, we’re very fortunate. Existing natural water quality is one of the main reasons we decided to grow in the San Luis Valley. When you’re starting something new, you have to look at your financial side of things. Investing in a hemp farm is very different than the marijuana side because you won’t make as much money per pound of product sold. So, you have to watch your budget and not spend too much, or you’re never going to make a profit.
The self-sustaining artisanal well and water rights were existing on the property. There’s no pumping required for it and the water goes into a 10,000-gallon holding tank, where we can monitor and test for water quality. In order to water our plants, we use a pump/drip water system that supplies water to each individual plant. It’s very efficient compared to most watering systems out there, such as flood irrigation or pivots, and really doesn’t use a heck of a lot of water.
Green: Are you growing in open air or greenhouses?
Craig: We grow in two 3,000 square feet industrial-grade greenhouses at Boot Ranch Farms. Greenhouse One has all the bells and whistles including heating, cooling, light deprivation, supplemental lighting, automated controls and more. That greenhouse allows us to mimic Mother Nature a little bit. We can get up to six harvests throughout the course of the year in that greenhouse. However, in reality, we get about four.
In addition, we have a second greenhouse that is set about 100 feet away and set up to keep plants growing on mother nature’s cycle. We can move groups of mature plants to Greenhouse One after each harvest for multiple flowering cycles. Lastly, between greenhouses, we have a 10,000 square foot courtyard that’s protected with shade cloth and other things to help protect those plants from the elements. In late October, all remaining plants in both greenhouses and the courtyard become mature and ready to harvest due to shorter days created by mother nature.
Green: Do you insure your crops?
Craig: We have not. Hemp is a new industry and we have not found good crop insurance.
Green: Do you cultivate your own genetics?
Craig: We work with some other companies here in Colorado to provide genetics. Consistent genetics are extremely important on the hemp side because we need to trust that they are going to keep the THC levels down. On the marijuana side, that part doesn’t matter so much
There are different strains that have been created that I absolutely love, and I’ve tried to stick with them and stay with that seed stock. One of them is called The Wife and the other Cherry Wine. Most of the best hemp I have found is based upon the Cherry strain. People are always looking for high CBD. I’d rather have a lower CBD level in the 8% to 12% range. Something higher in the 14% to 20% range has a higher chance of producing a product with more than the legal amount of THC.
Green: Is Harvey’s All Naturals fully supplied by Boot Ranch Farms?
Craig: Yes, it is. There are a lot of things that go into a quality product and we focus on that at Boot Ranch. We’re small, not trying to compete with the large-scale market. Unfortunately, a high percentage of the products out on the market come from large-scale industrial hemp grows. We focus on long-term medicinal value and grow very high-quality hemp and we try not to degrade it in any way, shape or form throughout processing.
Green: How many square feet or acres is the Boot Ranch Farm?
Craig: Boot Ranch farm is about 260 acres. We only grow on less than three of it.
Green: What’s your extraction process?
Craig: We use cold alcohol extraction. We do not distill to separate our alcohol from the hemp oil. We use what’s called a roto vape. That cold processing preserves our terpenes, it preserves our full-spectrum cannabis oil profile and doesn’t fully decarboxylate our CBDa. We want a large CBDa percentage because there are many things that CBDa is good for when it comes to long term medicinal reasons.
Green: Are you processing your own hemp?
Craig: No, we sub that part of it out. What I’ve learned in this industry is three main parts: 1- the farming; 2- the extraction, and; 3- the product line. Those are three very separate processes and require specialized expertise within themselves. Each is a large investment and it’s very hard to do it all. I decided to work with other people on the extraction part of it. They have the expertise, and we pay them well to do what they do.
Green: Okay, great. And then any final words for Ag Day?
Craig: Support your small farmer in nutrient-rich agricultural products.
Green: Great. That concludes the interview, Harvey!
