It is that time of year where the holidays afford us an opportunity for rest, recuperation and introspection. Becoming a new father to a healthy baby girl and having the privilege to make a living as a scientist, fills me with an immeasurable sense of appreciation and indebtedness. I’ve also been extremely fortunate this year to spend significant time with world-renowned cannabis experts, such as Christian West, Adam Jacques and Elton Prince, whom have shared with me a tremendous wealth of their knowledge about cannabis cultivation and the development of unique cannabis genetics. Neither of these gentlemen have formal scientific training in plant genetics; however, through decades of experimentation, observation and implementation, they’ve very elegantly used alchemy and the principles of Mendelian genetics to push the boundaries of cannabis genetics, ultimately modulating the expression of specific cannabinoids and terpenes. Hearing of their successes (and failures) has triggered significant wonderment and curiosity with respect to what can be done beyond the genetic level to keep pushing the equilibrium in this new frontier of medicine.
Lighting conditions can greatly impact the expression of terpenes (and cannabinoids) in cannabis.Of course genetics are the foundation for the production of premium cannabis. Without the proper genetic code, one cannot expect the cannabis plant to express the target constituents of interest. However, what happens when you have an elite genetic code, the holy grail of cannabis nucleotides if you will, and yet your plant does not produce the therapeutic compounds that you want and/or that are reflective of that elite genetic code? This ‘loss in translation’ can be explained by transcriptomics, and more specifically, epigenetics. In order for the genetic code (DNA) to be expressed as a gene product (RNA), it must be transcribed, a process that is modulated by epigenetic processes like DNA methylation and histone modification. In other words, the methylation of the genetic code can dictate whether or not a particular segment of DNA is transcribed into RNA, and ultimately expressed in the plant. To put this into context, if the DNA code for the enzyme THCA synthase is epigenetically silenced, then no THCA synthase is produced, your cannabis cannot convert CBGA into THCA, and now you have hemp that is devoid of THC.So what is the best lighting technology to enhance the expression of terpenes?
With all of that being said, how do we ensure that our plants thrive under favorable epigenetic conditions? The answer is the environment; and the expression of terpenes is an ideal indicator of favorable environmental conditions. While amazing anti-inflammatories, anti-oxidants and metabolic regulators for humans, terpenes are also extremely powerful anti-microbial agents that act as a robust a line of defense for the plant against bacteria and pests. So, if the threat of microbes can induce the expression of terpenes, then what about other environmental factors? I am of the opinion that the combination of increased exposure to bacteria and natural sunlight enhances the expression of terpenes in outdoor-grown cannabis compared to indoor-grown cannabis. This is strictly my opinion based off of my own qualitative observations, but the point being is that lighting conditions can greatly impact the expression of terpenes (and cannabinoids) in cannabis.
So what is the best lighting technology to enhance the expression of terpenes? Do I use full spectrum lighting or specific frequencies? The answer to these questions is that we don’t fully know at this point. Thanks to the McCree curve we have a fundamental understanding of the various frequencies within the visible light spectrum (400-700nm) that are beneficial to plants, also known as Photosynthetically Active Radiation (PAR). However, little-to-no research has been conducted to determine the impacts that the rest of the electromagnetic spectrum (also categorized as ‘light’) may have on plants. As such, we do not know with 100% certainty what frequencies should be applied, and at what times in the growth cycle, to completely optimize terpene concentrations. This is not to disparage the lighting professionals out there that have significant expertise in this field; however, I’m calling for the execution of peer-reviewed experiments that would transcend the boundaries of company white papers and anecdotal claims. In my opinion, this lack of environmental data provides a real opportunity for the cannabis industry to initiate the required collaborations between cannabis geneticists, technology companies and environmental scientists. This is one field of research that I wish to pursue with tenacity and I also welcome other interested parties to join me in this data quest. Together we can better understand the environmental factors, such as lighting, that are acting as the molecular light switches at the interface of genetics and transcriptomics in cannabis.
Earlier this week, a series of wildfires began ripping through Napa, Sonoma and Mendocino Counties, causing mandatory evacuations, rampant property damage and taking the lives of at least 17 people. Extraordinarily high wind gusts up to 50 mph have swept through communities in Northern California, leaving complete destruction in its wake.
According to The Washington Post, flames have reached more than 170,000 acres since Sunday when the fires began. The cause is still unknown. The President declared a state of emergency, allowing emergency funds to go to clearing debris and supplies for shelters. Nearly 25,000 have fled their homes to shelters in seven counties.
The area is well known for its wine production, an industry that is taking a very hard hit from the wildfires. It is also known as a productive cannabis growing area as part of the Emerald Triangle, synonymous with high quality, outdoor cannabis farms. A number of cannabis farms have been severely impacted by the flames.
We’ve received numerous reports of growers fleeing their homes and farms to get to safety. The LA Times reported that at least seven cannabis farms have been engulfed in flames. According to Amanda Reiman, vice president of community relations at Flow Kana, a distribution company working with cannabis farmers in the Emerald Triangle, they are in active evacuations and the fire is only about 5% contained. “It will be a while before we know the extent of the damage to our farmers and our community,” says Reiman. “The Emerald Triangle is a large region and central Mendocino county contributes a lot. Our farmers are resilient, but right now we are all focused on safety and vigilance.”
Kristin Nevedal, founder and chair of International Cannabis Farmers Association (ICFA), says she’s received information about cannabis farms being destroyed. “The true extent of damage to farms, lives and communities won’t unfortunately be known for sometime,” says Nevedal. “There is no rain in the immediate forecast, conditions are dry and we have had high winds.” Nevedal says the damage goes way beyond just a business setback. “Traditional sun grown cannabis farmers often live on the property they farm, so for many, a forest fire can mean not only loosing the crop but also their homes,” says Nevedal. “While there are fire insurance policies available for houses and outbuildings, the operational infrastructure components and the crop itself can be challenging or impossible to insure.” She says things like water storage tanks, water supply systems, irrigation systems, fences, water pumps and solar systems might not be insured at all. “Law enforcement in Mendocino is coordinating, to the best of their ability, with evacuees who have fire damage or have been evacuated, to insure public safety while assisting folks with repopulating their property and/or assessing the status of fire damage,” says Nevedal.
Because California is expected to implement their full adult use legalization in early 2018, the wildfires are particularly devastating to businesses that have been gearing up for the new market. To make matters worse, the fires came during peak harvest time, while growers are cutting plants and preparing their entire crops for distribution and sale.
Devika Maskey, founder of TSO Sonoma, a cannabis farm in Sonoma County, could only speak briefly because her farm is under evacuation orders. “We are getting all personnel off the hill to safety,” says Maskey. “The wind will be picking up to 40-50mph again later today.” Those high winds have the potential to spread the flames quicker, destroying more property and putting more lives at risk.
Maskey says the wildfires are having an enormous impact on their crops this year. “We do not have enough time to harvest the outdoor crop,” says Maskey. “So far there has been clear skies, but if the fire gets closer it can taint the buds with a smoky smell and flavor.”
Maskey says she has a number of friends in the cannabis space that have been severely affected already. “We do have a few friends that have lost their farms already,” says Maskey. “About a dozen other friends and family members who have lost their homes.” In Sonoma County alone, 5,000 people have been evacuated to shelters as of Wednesday morning, reports The Washington Post. “This has been a devastating week for many people and businesses,” says Maskey. “Our priority is getting everyone off the hill and to safety.” If you want to help the cannabis growers impacted by the fires, Maskey recommends donating to this growers relief fund or donate to the North Bay Fire Relief fund here.
Maintaining an environment that supports cultivation and keeps plants healthy is not an easy task. In cannabis growing, there are a variety of factors that greenhouse managers and personnel must monitor to ensure that their plants are in a healthy environment that fosters growth and development. Temperature, humidity, lighting and CO2 levels are a few of the conditions that need to be tailored to each cannabis greenhouse operation. However, it can be difficult to constantly monitor the status of your equipment and the greenhouse environment, especially after hours or during the off-season.
A remote monitoring system that’s properly selected and installed can help greenhouse managers keep their cannabis plants healthy, multiply their yields and increase return on investment. This type of system also helps operators identify patterns and trends in environmental conditions and get insight into larger issues that can prevent problems before they arise.
Here are some tips on key conditions to monitor and what you need to consider when selecting a monitoring system for your cannabis greenhouse operation:
Temperature plays a crucial role in any cannabis grow operation. The climate in your greenhouse must be warm enough to nurture photosynthesis and the growth of cannabis plants. Setting the incorrect temperature will significantly impact the potential yield of the plant and the rate at which it develops. A temperature too low will slow the growth of the cannabis, but too hot can lead to heat stress for your plants. The ideal temperature for a standard greenhouse is between 70 and 80 degrees Fahrenheit. However, depending on the stage of plant and desired growth densities, the temperature of the greenhouse needs to be adjusted accordingly.
Humidity directly affects plant photosynthesis and transpiration, so controlling humidity is vital in greenhouse growing. The ideal relative humidity (RH) for cannabis growth is around 60%. A low humidity level can cause water to evaporate too quickly for photosynthesis, while a humidity level that is too high can cause poor growth and possible mold and fungal disease. Monitoring the moisture content in the air of your greenhouse will help the plants during the transpiration process, increasing absorption of nutrients and overall health of the cannabis.
Your cannabis may be getting an abundance of natural light during the summer months, but maintaining adequate sunlight during the winter months can be a challenge. As a solution to this, many greenhouse managers equip their facilities with additional lights to supplement natural light during off-seasons or off-hours. To achieve the best possible yield, a cannabis plant in the budding stage should receive twelve hours of light each day, while other stages could require additional lighting. For example, the growth stage could require your cannabis to be exposed to sunlight for up to eighteen hours a day.
Like any other plant, cannabis requires CO2 to breathe. Greenhouse managers must set and monitor the CO2 levels in their facility to make sure that there is an adequate amount for the plants to develop, grow and be healthy. The amount of carbon dioxide required for your cannabis depends of the size of the facility and the amount of light the plants are receiving. However, a standard grow area for cannabis can maintain a CO2 range from 1000 to 1500 parts per million (PPM). A level below that threshold can result in slower growth of the plants, while a level above would lead to unused and wasted CO2.
Irrigation and Soil Moisture
One way to ensure a good yield from your cannabis is to water it regularly and monitor your soil moisture. Overwatering your plants can have the same effect, if not worse, than letting the soil become too dry. Plants’ roots need oxygen to survive, unlike leaves that breathe CO2, and when the soil is waterlogged the roots can’t provide their function. The lack of oxygen interferes with the roots’ nutrient uptake and photosynthesis causing the cannabis plant to wilt. The exact moisture content of the soil depends on the size of your greenhouse, temperature and humidity. Whether you hand water or are using a drip irrigation system, being aware of your soil moisture is vital to the long-term health of your cannabis.
Your greenhouse environment should mimic the ideal conditions in which cannabis plants flourish. With an indoor facility, you have the ability to control air circulation by venting hot air out and blowing fresh air in. Creating a circulation of air inside your greenhouse will increase your cannabis plant’s growth speed and yield. Additionally, an exhaust system helps control the temperature and humidity, while also preventing the invasion of mold and pests that thrive in hot, stagnant air.
When growing something of value, like cannabis, there will always be a threat of intruders. Whether your greenhouse is in a populated area or around hungry wildlife, any intruder could be detrimental to your overall yields and profit. Remote monitoring systems can give you peace of mind and instantly alert you when there is an unwanted presence in your greenhouse.
Knowing all the possible threats to your cannabis greenhouse helps you evaluate your specific needs, and ultimately identify the proper remote monitoring system.
Selecting the Right Monitoring System
Other factors to consider when choosing a monitoring system right for your operation include:
Base unit and sensors
Wireless or hardwired sensors
Communications to your site (Phone, cellular, Wi-Fi, etc.)
Programming and status checks
Return on investment
Base Units and Sensors
Each condition in your greenhouse that you want to monitor requires its own input on the base unit of the monitoring system. You must match your needs with the number of inputs available. A good fit for a smaller cannabis greenhouse may be a lower-cost, non-expandable monitoring system. However, larger facilities have many monitoring points and more people to alert when there’s a problem. If your cannabis operation is poised for growth, purchasing an expandable system could add value to the initial purchase because you wouldn’t have to replace your entire system in the future.
Your monitoring system should also have an internal rechargeable battery backup to ensure continuous monitoring and alerts in the event of a power outage. It is also recommended to have each base unit in a sheltered enclosure to protect it from moisture, dirt and other hazards.
Placement of sensors is also crucial. For example, temperature sensors in your greenhouse should be placed throughout the facility. They should be next to your thermostat and in the center of your greenhouse, preferably away from direct sunlight.
Wireless or Hardwired Sensors
Remote monitoring systems offer the option to have sensors hardwired directly to the base unit or sensors wirelessly connected. A hardwired monitoring system connects the sensors to the base device with wires. Generally, trenching long distances for wires is time consuming and costly. So alternatively, a wireless system uses built-in radio transmitters to communicate with the base unit. Some monitoring systems can accommodate a combination of hardwired and wireless sensors.
Communications to Your Site
Monitoring devices that use cellular communications must be registered on a wireless network (like Verizon or AT&T) before you can send or receive messages. Because cellular devices perform all communications over a wireless network, it is important that there be sufficient signal strength at the greenhouse. It is a good idea to check the signal quality in the area before purchasing a cellular product. If the cellular network has less than desirable coverage, it is possible to install an external antenna to help increase cellular signal.
When monitoring systems identify a change in status, they immediately send alerts to people on the contact list. If you don’t want all of your personnel to receive notifications at the same time, certain devices can be programmed to send alerts in a tiered fashion. It is important to consider the reach of the communications, so that you’ll be notified regardless of your locations. Multiple communications methods like phone, email and text provide extra assurance that you’ll get the alert. Also, note of the number of people the system can reach and if the system automatically cycles through the contact list until someone responds. Make sure the system allows for flexible scheduling so that it doesn’t send alarms to off-duty personnel.
Programming and Status Check
If you’re responsible for maintaining a commercial greenhouse facility, you want a system that will provide real-time status of all monitored conditions on demand. There are a few different ways to access your sensor readings. Options include calling to check status, viewing a web page, either on a local network or on the cloud, or accessing the information via an app on your mobile device. With a cloud-based system, the devices supervise themselves. This means if the internet or cellular connection goes down, the device will send an alarm to alert the appropriate personnel.
If you don’t select a cloud-based system, you will be limited to logging in through a local area network, which will allow you to make programming changes, access status conditions and review data logs. If internet connectivity is not available at your location, you will want to choose a cellular or phone system rather than Ethernet-based option.
Data history is valuable in identifying patterns and trends in your cannabis greenhouse conditions. Manually monitoring and recording environmental parameters takes a significant amount of personnel time and detracts from other important workplace demands. However, many monitoring systems automatically save information, recording tens of thousands of data points, dates and times. Cloud-based logging provides an unlimited number of records for users to view, graph, print and export data trends.
Analyzing data samples may lend insight to larger issues and prevent problems before they arise. For example, if the data log shows power fluctuations occurring at a regular time, it could be indicative of a more serious problem. Or, if the data shows signs of a ventilation fan or supplementary lighting beginning to malfunction, they can be repaired or replaced before total failure occurs.
Return On Investment
When deciding how much you should pay for a remote monitoring system, tally up the entire cost, fully installed with additional peripherals and sensors and any labor fees for installation. Then consider the value of your cannabis plant inventory and greenhouse equipment. Finally, factor in the cost of downtime, should an environmental event shut down your operation for a period of time.
Choosing the right greenhouse monitoring system and sensors could mean the difference between life and death for your cannabis plants. Understanding the conditions you need to watch and monitoring systems’ capabilities are they best way to protect your investment.
Adam Jacques and his team officially launched the newest arm of their business last week, Sproutly, a dispensary located in Eugene, Oregon. “This is an extension of what the Grower’s Guild Gardens does and what the Microgrower’s Guild was,” says Jacques. The Grower’s Guild Gardens, Jacques’ award-winning cultivation business, is known for their high-CBD genetics and patient-focused work, most notably with Leni Young, which helped lead to the passing of legislation in Alabama called Leni’s Law, decriminalizing the possession of cannabis oil for patients in the state.
Sproutly is a medical and recreational dispensary that boasts a wide variety of high-CBD strains, a reflection of the team’s focus in the past. “We are extremely medically focused with a variety of unique CBD strains in stock,” says Jacques. “First and foremost are the patients, but entering the recreational market means we will be carrying a wider variety.” The opening of the dispensary is well timed as the team received their Tier II cultivation license, allowing them to grow cannabis up to 20,000 square feet in an outdoor space and 5,000 square feet indoor. So in addition to the handful of brands they carry, including Lunchbox Alchemy edibles, Northwest Kind and Marley Naturals, they also carry over 75 strains from their own Grower’s Guild Gardens.
Adam and Debra Jacques pride themselves in rigid standards for quality in sourcing, so it should be no surprise that they plan on supplying their dispensary with over 150 strains coming from more than 1,200 plants on their farm. “We really only take products from people we know and trust,” says Jacques. “That is why most of the flower in the dispensary is coming from our farm, so we know exactly what is going into it.” Jacques points to third-party certifications such as Clean Green, for other vendors to find reputable growers. “I need to know where it is coming from and that requires a personal relationship to trust the quality of their products.” The value of trust and personal relationships is also why they go through extensive training of their staff, using their own expertise for in-house training.
The team includes Chris West, Elton Prince and John De Kluyver, all of whom have a decade or more of experience cultivating cannabis and working with patients. “We take our bud tenders through training classes, they get tested on their knowledge of products and the science of cannabinoids and terpenes and how the combinations affect people differently,” says Jacques. By leveraging that high level of in-house expertise, the team prides themselves on customer service, helping patients and customers find the right strain or product that suits them best.
In the front of the dispensary, a receptionist greets patients or customers, checking identification and showing you to a bud tender. As you walk into the retail space, you immediately notice the professionalism of the staff, taking time to personalize each customer’s experience without making him or her feel rushed. The clean aesthetics, product selection and knowledgeable staff provide for a friendly retail culture without the common ‘stoner culture’ that usually follows.
Jacques and his team will not be trading in their overalls and work boots just yet as they are inching toward harvesting their 1,200 outdoor cannabis plants soon. Grinning ear-to-ear, Jacques showed off his Tier II cultivation license on the farm, and with it came a glimpse into their exciting growth.
Canada’s new ACMPR was launched late last month on August 24th. The key change that most notice is that Canadians may now again grow their own cannabis at home for medical purposes. In addition, more strict guidelines for product testing and labeling requirements for Licensed Producers (LPs) were released.
Short term pain for long term gain. While the combination of allowing patients to grow at home and more strict regulations for LPs may at first seem like a business disadvantage; overtime LPs will be thankful for the combination switch. Health Canada’s new requirements encourage a leveling of the playing field globally between LPs and large scale product manufacturers of pharmaceuticals, therapeutics and natural health products. The steps Health Canada is taking to regulate our producers, is exactly what they need to get ready for mass production that will be necessary for recreational markets, scheduled for release in Spring 2017.
Picture rows of Tylenol bottles on the shelf at your favorite pharmacy. Now picture rows of cannabis bottles on the shelf beside them. This is what medical cannabis will look like in Canada perhaps as early as 2018, if not sooner. With just under forty LPs on the map and a projected sales volume of modest billions, Canada’s LPs’ eyes are widening with dollar signs as they lube up their oil production and more to see what shelves in Canada will hold.
Curious to know more? Our regulatory department manager Elfi Daniel-Ivad is an expert in regulatory change. She has worked on close to 150 submissions for cannabis licensees in Canada and beyond. Here are a few key changes from her department’s overview to better understand.
No personal production or designated production available to patients (aside from that grandfathered in by MMAR).
Personal production and designated production available. Patients may grow 5 indoor plants OR 2 outdoor plants at any given time per gram prescribed to them.
Licensed Producers were not required to label THC or CBD amounts in dried cannabis, though most producers did for sales and educational purposes. Oils had to be labeled with THC and CBD amounts.
Licensed Producers must label their percent THC and CBD for dried and fresh cannabis products.
For the labelling of oils, the total quantity of THC, CBD and oil in a container had to be shown. Restrictions on THC allowed no more than 10mg/mL THC per capsule and no more than 30mg/mL THC per mL oil to be distributed.
In addition, oil labels must now include information on “carrier” oil and allergen information. Containers must be labelled with number of capsules, the net weight and volume of each capsule. .
No reference to validation of analytical testing methods.
Analytical testing must be completed using validated testing methods; confirming reliability and consistency in results for contaminants, disintegration, residues and THC, THC-A, CBD and CBD-A
Accredited labs can only test products as received from Licensed Producers.
In addition to Licensed Producers, patients growing their own or having a designated grower growing for them may also test their products at an accredited lab.
In addition to these changes, it is important to note that if an individual or company has an MMPR proposal already submitted they can now revise it to include oil production (previously, it was first dried bud only). If a company submits a new ACMPR proposal, they can include oil production on their application right away. Interested in submitting your own application? Or need help with one in the USA? Our regulatory department would be happy to answer any questions you might have about the process.
Successful cannabis cultivation practices leverage commercial agricultural industry practices for the most efficient and cost-effective production of the crop. Since the 1990s, the cannabis industry has cultivated primarily in indoor warehouses and outdoor farms, however the industry is experiencing a significant shift toward greenhouses.
What are the considerations when deciding between a warehouse and greenhouse? The panel shares four factors around the costs and operational challenges, and the benefits of a greenhouse.
Maximize Efficiency in Every Process
Why are cannabis cultivators looking toward greenhouses? Peterson says it is all about efficiency. “In a warehouse, electricity costs can run up to 50 percent of the total cost of goods sold, which is a tremendous amount that can be decreased by switching to a greenhouse,” says Peterson. “In a greenhouse, you can add supplemental lighting to augment what the plant is receiving from the sun.”
For cultivators, Peterson noted that it is critical to ensure growers have experienced vendors and advisors on the team to help maximize the efficiency of the greenhouse. “As the cost of this product comes down, the efficient growers will be the ones in it for the long haul,” added Peterson.
Construction vs. Operating Costs
The panel identified upfront cost as one of the biggest challenges faced when building out a greenhouse. “The cost of retrofitting a warehouse and building a greenhouse are similar, but where you will save is in the operational costs,” says Peterson. “Lighting can be up to one third of your total cost in indoor facilities, when you switch to a greenhouse that cost can be reduced by 50 to 70 percent.”
Brady acknowledged that some traditional greenhouses have challenges in controlling the environment, but automated greenhouses offer retractable roofs and siding. “If you have the resources to invest in your greenhouse system upfront, that is generally a better way to save money in the long run,” says Brady. “Managing pests in greenhouses can also become very challenging if you don’t have the proper climate regulations.”
Lighting for Your Greenhouse
One of the greatest benefits of growing in a greenhouse is the ability to source natural light. But what about the required light levels? Peterson pointed out that light levels change throughout the year and the plants have different light needs in different stage. Supplement with a lighting system that can read the natural light levels received over any given period of time and be adjusted accordingly. “Greenhouse facilities also need to be outfitted to meet the needs of the cannabis plant, which differ in some ways from other agricultural crops,” says Peterson.
Peterson explained that every light is designed with a different purpose in mind. “There are different lights for indoor warehouse facilities where the lighting system provides 100 percent of the available light for cannabis growth versus supplemental lighting for greenhouses,” Peterson adds. “The key is to measure how much light is actually delivered by the sun on a daily basis, which changes throughout the year; at urban-gro, we supplement the facility with light fixtures that will not create shadowing during hours of sunlight and adjust to reach the optimal collective light levels.”
With LED lighting a hot button topic, Peterson explained that the most important consideration for any light fixture, whether LED or HPS, is it’s efficiency capacity. “It all depends on the budget and payback period and a lot of numbers need to be crunched,” says Peterson. “Yield is directly correlated to light; planning properly, sealing your environment, making sure you have the right target DLI, and buying good light meters, are all key.”
Make a Positive Impact and Quality Product
Brady noted that industry leaders are conscious of positive impact towards human health and environmental stewardship when moving to a greenhouse. Cultivators may find the process challenging initially, however the facilities are quite easy to operate and manage, and allow stress-free cultivation of commercial-scale crops.
Keich added that the cannabis industry is becoming more like commercial agriculture. By utilizing the correct technologies and regulators, greenhouse cultivation makes the crop smell, taste and look that much better. “Let’s use natural sunlight to minimize costs and be environmentally friendly to produce a superior product,” says Keich.
Peterson wrapped up by stressing that cultivators should evaluate the greenhouse environment and lighting to improve their bottom line. “Look at the most efficient way to lower your cost of goods sold. Lighting is a very big component to that,” she continued. “Make sure you evaluate the efficiency of the fixture and ask the questions: Why are we targeting this light level? Is the color spectrum correct? Are you measuring in micromoles per watt? These are all different questions, however figure out how much light is coming out of the fixture and verify it for yourself, and you will be successful,” says Peterson.
A few weeks ago, it was that time of the year when people set new year’s resolutions hoping to accomplish a set of goals or somehow better themselves. More often than not, those expectations never get met and those resolutions remain unfulfilled, lofty ambitions.
The cultivation of cannabis is a production process that is notoriously inefficient and energy-intensive. Indoor growing requires a very large carbon footprint. In 2015, we saw the country’s cannabis market grow to roughly $2.7 billion. Looking forward to 2016, we can expect more growth with multiple states voting on recreational sales including California and Nevada, leading to more growers and a higher volume of cannabis production across the nation.
I am suggesting a resolution for cultivators to adopt: Grow your cannabis more sustainably. This might seem unattainable, but the key to a good resolution is a force of habit, setting small goals to improve your production process and make your operation more efficient, ultimately saving you money and reducing your carbon footprint. This series will delve into some of the tools cultivators can use to grow cannabis more sustainably.
Environmental, social and economic sustainability are the three pillars of sustainability to keep in mind. Many describe it in terms of people, planet and profit in reference to the Triple Bottom Line of 21st Century Business. Essentially, cultivators should adjust their standard operating procedures and business model to include their responsibility to be environmentally, socially and economically sustainable.
The challenge of growing cannabis efficiently is understandably daunting. A research study published in the journal, Energy Policy, suggests, “One average kilogram of final product [dried flower marijuana] is associated with 4600 kg of carbon dioxide emissions to the atmosphere.” That translates to an enormous carbon footprint, the equivalent of roughly three million cars.
The use of pesticides is also a tangible social and environmental issue of sustainability because of the potentially harmful effects on the cultivation environment and the consumer. Just last week, Denver recalled almost 100,000 edibles due to concerns of dangerous pesticide residue. Growing pesticide-free marijuana is more sustainable across the board for obvious reasons; it is safe for the consumer, less harmful to the environment and more marketable as a clean and safe product.
There are a lot of tools in the cultivator’s arsenal they can use to work toward a more sustainable operation. Some of these include more energy efficient technology, like LED lighting and efficient HVAC systems. Some tools require more effort to implement like moving toward greenhouse growing, using post-consumer products, support fields, composting and others.
In this series, we will hear from growers offering advice on some of the steps you can take to grow your cannabis with sustainability at top of mind. Alex Cooley, vice president of Solstice, a cultivation and processing business in Washington, will share some insights on the sustainable technologies you can implement to improve efficiency in your grow operation. Stay tuned for Part II of Sustainability of Cultivation in 2016.
Throughout the United States, a majority of cannabis for medical and adult use is grown indoors, which requires a tremendous amount of energy and is generally inefficient. State regulators and cultivators alike are beginning to notice the benefits of greenhouse and outdoor-grown cannabis, primarily for energy efficiency and environmental sustainability.
Edible Garden is certified by the Global Food Safety Initiative (GFSI), which provides internationally recognized benchmarks and guidance for managing food safety and meeting standards. According to Ken VandeVrede, chief operating officer of Terra Tech, the company plans to take these cutting-edge practices and standards from cultivating produce to the cannabis industry to grow quality, sustainable and safe cannabis in states where it is currently legal.
The company is actively making its operations more environmentally sustainable via greenhouse cultivation, Dutch style hydroponics, shipping locally, and integrated pest management. “We plan on implementing guidance from our two years of GFSI certification and our organic certification along with all of our practices from the food side and bring them to cannabis; for us, it is just another plant,” says VandeVrede. With the help of computer automation, he says they can cultivate cannabis at the commercial scale, creating more homogeneity by removing human elements and utilizing environmental controls. Through computer automated blackout curtains in their greenhouses, they plan to minimize energy usage by using natural sunlight when possible.
“The procedures are very similar across industries so we are creating our own internal standards for cannabis cultivation,” says VandeVrede. “We are trying to be at the forefront of the industry and set the standard for growing cannabis, because right now, there are no standards in place.”
Terra Tech has already started its move into the cannabis industry via its subsidiary, IVXX LLC, which makes medical cannabis extracts for dispensaries in California. The company has also broken ground on cultivation and production facilities in Nevada and dispensaries in California, and submitted an application for licenses in Maryland. “Terra Tech is doing everything with vertical integration in mind; we will control the cultivation, bringing experience from our agricultural background to cultivate high quality and high yield cannabis, making oil and extracts with it to sell in our dispensaries,” adds VandeVrede.
Looking to the future of cannabis cultivation, Terra Tech’s plan is to keep environmental sustainability at top of mind. “As a company we are growing indoor, but moving toward greenhouse cultivation across the board”, says VandeVrede. “Our focus on expansion will be [include] greenhouse-grown cannabis, which is a lot more efficient, saving us money but more importantly reducing our overall carbon footprint.” With more companies adopting these sustainable farming practices, the industry might soon usher in a new era of environmentally friendly cannabis cultivation.
