Flower-Side Chats Part 2: A Q&A with Bill Conkling, Founder and CEO of Maggie’s Farm

By Aaron Green

Flower continues to be the dominant product category in US cannabis sales. 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 navigate a rapidly changing landscape of regulatory, supply chain and consumer demand.

Maggie’s Farm is an integrated cannabis company based in Southern Colorado. Maggie’s Farm has seven adult-use and medical dispensaries and cultivates the vast majority of their flower on outdoor farms. All Maggie’s Farm products are sun-grown from seed in soil that is 100% custom-mixed onsite as well as spring-watered, slow-cured and hand-trimmed. Maggie’s Farm does not use any synthetic pesticides or growth hormones in its cultivation. In addition, for the past eight years, Maggie’s Farm has recently obtained Clean Green Certified®, a designation certifying organic standards and testing that mirrors the USDA organic certification. Maggie’s Farm was the first cultivator in Colorado to earn the Clean Green certification.

We spoke with Bill Conkling, Founder and CEO of Maggie’s Farm to learn more about the benefits of outdoor growing, localism and their Clean Green certification. Bill started Maggie’s Farm in 2010 after growing up on cattle ranches and farms in Colorado.

Aaron Green: Bill, thanks for taking the time today. Tell me a bit about how you got involved in the cannabis industry.

Bill Conkling: I am a native of southern Colorado. I was a medical caregiver back in the early days of legalization, and I saw an opportunity to vertically align after my first legal crop in 2010. I opened up the store in 2011. I’ve been a lifelong proponent of medical, recreational and adult use of marijuana.

I come from a background of farmers and I had worked on cattle ranches and farms throughout childhood. As soon as I graduated from college, I went back to work on a large cattle ranch in the four corners area [of southern Colorado]. That’s where I started to incorporate my indoor cultivation experience and skills with outdoor.

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

Bill: I was one of the first medical operators to support legalization, so I have certainly followed legalization trends. I’ve looked at some other states in our region in terms of growth and legalization.

Bill Conkling, Founder and CEO of Maggie’s Farm

We’re trying to stay a regional supplier and producer so that we are locally grown. We believe the southwest of Colorado is optimal for outdoor cannabis cultivation.

At Maggie’s Farm, we have followed an organic trend from the beginning and I think that’s becoming more of a trend now. We recently received Clean Green certification to that effect. Our goal is to try to provide the healthiest product at a good value to the market.

I believe that all of the products that are made in the cannabis world come from the flower. Downstream products are only as good as their ingredients. It all starts with the flower. So, we focus on producing a clean, top-shelf quality flower that is produced outdoors.

Aaron: How do you define local?

Bill: Local is staying in the climate that is optimal with the least amount of carbon footprint to the earth. That also means trying to operate so that we’re not moving a lot of product across long distances.

We’re trying to set up farms that are in optimal climates. There is a two or three-state region that I believe is the optimal climate for outdoor marijuana cultivation in our country.

Aaron: What states are those specifically?

Bill: I think Colorado and New Mexico, primarily.

Aaron: What geographies is Maggie’s farm currently in?

Bill: We’re in southern Colorado. We don’t go into the plains of Colorado.

Aaron: So Colorado state only right now?

Bill: Yes. The wet mountain range is one of the mountain ranges that we are in. I’ve also cultivated in the La Plata mountain range.

Aaron: What specifically is it about that region that makes it conducive to cannabis growing?

Bill: I think if you get the right elevation and the right microclimates within those elevations, and you have the number of sunny days that Colorado offers in those areas – the intensity of the sunlight, and the cool nights – all those things are factors that coincide in these areas that we like to cultivate in.

Aaron: We’ve been talking about outdoor growth. Does Maggie’s do any indoor?

Bill: No. We’re essentially an outdoor farm. We do a little bit of breeding and we’ve got starter houses, greenhouses and hoop houses for that purpose. We’ve got one greenhouse that we use for some wholesale, but we are primarily outdoors.

Aaron: How do you go about selecting the genetics or evolving the genetics to meet your local environment, given that you’re growing outdoors?

Bill: A lot of it is honestly through testing and experimentation, historically. You just cultivate and harvest and see how the genetics performed, you know? You test, you take test inputs, you take customer reviews, and blind test results from the team and from the customers and you consider all those facts.

Aaron: Do you produce and use your own seeds or are you purchasing those?

Bill: We have done both. I think I’ve probably created somewhere north of 800 different strains at this point. So, we’ve got a huge seed bank. We do also buy from vendors and experiment with some of those genetics as well.

Aaron: Do you market your seeds in Colorado?“I don’t think that you can get anywhere near the terpene value indoors that you can outdoors.”

Bill: We do not.

Aaron: How did you settle on outdoor-only as the strategy for Maggie’s?

Bill: I believe outdoor is a premium flower. I think it has less impact on the earth. I think that there is a lot less pest mitigation than there is indoors, which makes it a healthier, cleaner product. You don’t have to mitigate the concentration of pests that you get in temperate climates of stagnant corners of greenhouses and buildings that you cultivate indoors. Therefore, you never get into the situations as often or as intensely, where you might have to really work hard at mitigating your pests. You can use the natural predator insects you can introduce and oftentimes they survive and they create their own climates and it’s a more natural, healthier product.

I don’t think that you can get anywhere near the terpene value indoors that you can outdoors. You just don’t have the value of the sun, which nothing compares to. You can hold up as many high wattage bulbs as you want and you don’t even pale to the sun and the effect that the sun has on the flower.

Aaron: What are some of the challenges of growing outdoors that you see frequently?

Bill: You have to be nimble. You can’t rely completely on a schedule. You’ve got to be able to shift around in your planting days and your harvest dates.

You’ve obviously got to be on your toes all the time for weather changes. Higher humidity years can tend to bring more insects or pests. Some years you’ve got higher winds than other years. This year, we had a snowstorm on September 9, which left nine inches of heavy wet snow on one of our farms. So, you’ve got to be nimble, very proactive and ready for those kinds of weather events that happen in very short notice.

Aaron: We mentioned Clean Green Certified® briefly. Can you explain more about the Clean Green certification and why that’s an important thing for you at Maggie’s?

Bill: The choice to become Clean Green Certified® was really an effort to validate the organic process that we have. We vetted out what we believe was and still is the premier, organic criteria certification endorsement in the market for cannabis. To this day, they really do an ethical, vetting-out process whereby if you fail the parts of any of the soils that are sent to federal-licensed labs, you do not get your endorsement. The owner of Clean Green also had a mother company that was an endorser of other agricultural products such as coffee, wheat and dairy.

Aaron: How would you compare Clean Green Certified® to USDA Organic?

Bill: Identical. When the federal government legalizes, we are poised to automatically convert to a USDA Organic certification and endorsement. The processes the founder and owner of Clean Green uses to test cannabis is the same process used to test other agricultural industries. For plants, he takes random samples of soils throughout a cultivation field and sends them to a federal-licensed lab where they test for impurities.

Aaron: Did you decide to get your Clean Green certification due to pulling from the market, or is this more something you decided to do internally as Maggie’s Farm?

Bill: I decided to do this internally. I wanted to be recognized for all of our organic efforts and I wanted to let people know that we have a safe product that doesn’t have synthetics in it. Even to this day, a lot of people in Colorado unlike the coastal states like maybe California are still pretty unaware of a Clean Green certification or even the fact that there is an organic process for cannabis or marijuana. So, it’s really just to let our customers know that there is value in a safe, healthy choice for them.

Aaron: What kind of products do you create at Maggie’s farm?

Bill: We grow flower. We are also a big producer of a very high-quality pre-roll. We are developing promoted products as well.

Aaron: Do you do fresh frozen?

Bill: We do some, yes.

Aaron: Are you selling direct to the dispensary or to manufacturers?

Bill: We finally had produced some excess. So, we started wholesaling flower this year and lots of high-quality shake for concentrates to concentrate makers. Our customer is typically a little more of a mature customer. I don’t want to say necessarily older, but I think we probably do hit a little bit of a higher, more experienced, health-conscious, connoisseur customer.

Aaron: Can you give me an idea of some of the regulatory challenges in Colorado that you’ve faced in the past or are facing today?

Bill: The perpetual change of regulation has been a challenge. Being a competent operator in cannabis means getting used to the change and having the resources to be nimble with compliance. We haven’t had common problems such as metals, mold or mildew issues. However, we have had some hardware issues, which required us to change cameras along with other technical intricacies.

Aaron: How many acres do you have?

Bill: We have about 30 acres of secured premise cultivation.

Aaron: Is that all managed in-house or sublet?

Bill: It’s all managed and operated exclusively by Maggie’s Farm.

Aaron: What’s next for Maggie’s Farm? What are you excited about?

Bill:  We want to continue to put a higher scale of a very healthy, quality, value flower out there and to be able to offer that to more states initially states that are within our region and eventually states across the US. Also, we will continue to do our best to meet the growing demand for healthier choices in general.

Aaron: Lastly, what are you personally interested in learning more about?

Bill: How we can continue to be as earth-conscious as we can be? How we can continue to look for ways to give back to our communities? How we can continue to operate as a view of made in the USA and to try to just support local regional and national products and vendors? Just how to be more aware and always look for opportunities for self-improvement.

Aaron: That concludes the interview, thank you Bill!

The West Coast Wildfires: What is the Impact on the Cannabis Industry?

By Aaron G. Biros

Since the beginning of this year, more than 8,100 wildfires have burned in California, torching a record 3.7 million acres of land in a state with one of the largest cannabis economies in the world. With the effects of climate change continuing to wreak havoc on the entire West Coast, smoke from those fires has spread across much of the country throughout the summer.

As we approach October, colloquially referred to as Croptober in the outdoor cannabis market for the harvest season, we’re seeing the August Complex Fire creep towards the Emerald Triangle, an area in northern California and southern Oregon known for its ideal cannabis growing conditions and thousands of cultivators. The wildfires are close to engulfing towns like Post Mountain and Trinity Pines, which are home to a large number of cannabis cultivators.

Hezekiah Allen, executive director of the California Growers Association, says losses could reach hundreds of millions of dollars. Fires across Oregon have torched dozens of cultivation operations, with business owners losing everything they had. The Glass Fire has already affected a large number of growers in Sonoma and Napa Counties and is 0% contained. None of these cultivators have crop insurance and many of them have no insurance at all.

The impact from all of these fires on the entire cannabis supply chain is something that takes time to bear witness; a batch of harvested flower typically takes months to make its way down the entire supply chain following post-harvest drying and curing, testing and further processing into concentrates or infused products.

The fires affect everyone in the supply chain differently, some much more than others. Sweet Creek Farms, located in Sonoma County, lost all but one fifth of their crops to fires. Other cultivators further south of the Bay Area have lost thousands of plants tainted by smoke.

Harry Kazazian, CEO of 22Red, a cannabis brand distributed throughout California, Nevada and Arizona, says he is increasing their indoor capacity to make up for any outdoor flower loss. But he said it has not impacted his business significantly. “Wildfires have been a part of California and many businesses have adapted to dealing with them,” says Kazazian. He went on to add that most of his flower comes from indoor grows in the southern part of the state, so he doesn’t expect it to impact too much of his supply chain. Kazazian is right that this is not a new concept – the cannabis industry on the West Coast has been dealing with wildfires for years.

George Sadler, President of Platinum Vape

George Sadler, President of Platinum Vape, has a similar story to tell – the fires have impacted his supply chain only slightly, saying they had a handful of flower orders delayed or cancelled, but it’s still business as usual. “It’s possible this won’t affect the supply chain until later in the fall,” says Sadler. “There has definitely been an effect on crops that are being harvested now. It may end up driving the price of flower up, but we won’t really know that until January or February if it had an effect.”

Sadler believes this problem could become more extreme in years to come. “Climate change definitely will have an effect on the industry more inland, where we’re seeing fires more commonly – it could be pretty dramatic.”

One beacon of hope we see every year from these fires is how quickly the cannabis community comes together during times of hardship. Sadler’s company donated $5,000 to the CalFire Benevolent Foundation, an organization that supports firefighters and their families in times of crisis.

A large number of cannabis companies, like CannaCraft, Mondo, Platinum Vape and Henry’s Original, just to name a few, have come together to help with relief efforts, donate supplies, offer product storage and open their doors to families.

If you want to help, there are a lot of donation pages, and crowdfunding campaigns to support the communities impacted. The California Community Foundation has set up a Wildfire Relief Fund that you can donate to.

This GoFundMe campaign is called Farmers Helping Farmers and still needs a lot of funding to reach their goal. Check out their updates section to see how they are helping cultivators in real time. This Leafly page is also a very useful guide for how you can donate supplies, volunteer and help those impacted the fires.

Why You Should Consider Parametric Insurance to Protect Your Outdoor Cannabis Crop

By Evan Stait
No Comments

In May 2019, there were 4,400 reports of tornadoes, hail and high winds across the U.S. That’s the highest number of similar weather incidents on record since 2011. This increasing number of weather incidents has a huge effect on the cannabis industry, which has turned more frequently to outdoor cultivation since legalization.

While outdoor cultivation can develop the flavor of the cannabis crop, much like wine, it also brings with it some unique challenges. Each component of the weather – wind, rain, temperature – plays a role in whether a crop succeeds or fails. While conditions one year may easily lead to a bumper crop, the conditions the following year may not be as favorable. And as the weather becomes more volatile due to climate change, growers are ever more at risk, especially when they aren’t insured.

Evan Stait, author and commercial account executive for HUB International

Unfortunately, traditional crop insurance isn’t available for outdoor cannabis cultivators, primarily because of a lack of data on yield performances – and the impact the weather has on yields. Insurance companies don’t create policies until they have the data to back the policy. But meanwhile, the growers are assuming all the risk.

Enter parametric insurance. Parametric insurance is a program that pays out after a certain parameter is met. In the case of cannabis growers, the parameters are weather-related. The policy is triggered when the weather varies from the average – if there is too much rain during a specific period of time, for example, or an occurrence of large hail. Because the policy is related to average weather, it has to be tailored to the specific growing region – which means the parameters for Colorado won’t be the same as a policy for Maine.

For cannabis crops, coverage can be created for the following parameters:

  • Rain (recorded in inches of rainfall over a period of time)
  • Wind (recorded in miles per hour)
  • Early freezing (using recorded temperatures)
  • Hail (measures intensity and size of the hail)
  • Drought (for non-irrigated plots)

Once a parameter has been set, the policy starts to pay out at the strike point, or the average measurement specified in the policy. Coverage continues to pay out until the exhaust point, or the entire limit of the coverage is paid out. It works well because it’s straightforward: The further away from the average, the more the likelihood of catastrophic loss.

Parametric insurance isn’t for everyone. It’s a program designed to fill gaps that exist within the traditional insurance system. Nor is it designed to stand alone. But it can protect outdoor cannabis cultivators from weather risks that are truly beyond their control, especially given the hardening property insurance market.

In addition, it works for two simple reasons:

  1. Simplicity: Recorded weather events leave no room for ambiguity or dispute. You don’t even need an adjuster to guide the claims process. The official weather data proves what happened.
  2. Correlation: There is a high degree of correlation between measurable weather events and potential damage to outdoor crops.

Parametric coverage is not widely available. Many insurance professionals may not even know of it. But with the property insurance market hardening and a growing need to protect you and your cannabis business from weather-related disaster, parametric coverage may be your best bet. Make sure you speak to a broker who knows about it.

Sustainable Hemp Packaging is the Future of Industrial Packaging

By Vishal Vivek
4 Comments

The future of packaging is ripe for capitalization by the drivers of sustainability culture. With the battle lines drawn and forces at play in motion, change is now inevitable. The question arises: how quickly can the industry grow in the space of the next decade?

With an increasing number of nations banning non-biodegradable and petroleum-based plastics in certain uses, the choices at hand have naturally led to bioplastics. Bioplastics are a major ingredient of the renewable packaging industry. We derive them from various renewable agricultural crops, of which hemp is among the chief examples.

The Change for Hemp

The legal ramifications of the European Green Deal and the American Farm Bill of 2018 have created a microcosm where the sustainability discussion has turned into corporate initiatives for crops like industrial hemp, which are a source for bioplastics and numerous other products. The smaller carbon footprint of industrial hemp plays its role in shaping consumer demands towards a greener future.

Farmers are now able to cultivate the plant in the U.S., due to its removal from the list of controlled substances. Agribusinesses and manufacturers are aware of the plant’s versatility, with uses in packaging, building construction, clothing, medicinal oils, edibles like protein powder and hemp hearts, hemp paper and rope. What was once George Washington’s strong consideration as a cash crop for his estate, may gradually become the world’s cash crop of choice.

Hemp’s Sustainability Beckons 

Why is the crop unanimously superior in the aspect of eco-friendliness? Its growing requirements are frugal: water, soil nutrients and pesticides are not needed in large quantities. It absorbs great quantities of carbon dioxide from the atmosphere, and uses it to create 65-75% cellulose content within its biomass. Cellulose is vital in the manufacture of bioplastics. Hemp is also flexible within crop cycles, due to its small harvesting period of only 4 months.

Thus, farmers use it as a rotational crop, allowing them to also cultivate other crops after its harvest. High-quality crops like cotton, though superior in cellulose content and fibrous softness, require far more water quantities, soil nutrients and pesticides. Farmers face greater difficulties in cultivating cotton as a rotational crop, because it requires far more space and time.

Hemp Bioplastics For Packaging                                

We manufacture bioplastics from the hurd and cellulose of the hemp plant. Hemp bioplastics are biodegradable, and take up to a maximum of 6 months to completely decompose; by contrast, normal fossil-fuel-based plastic takes up to 1000 years to decompose.

Manufacturers incorporate these ingredients into existing manufacturing processes for regular plastics, such as injection molding. Thus, we can apply bioplastic ingredients to similar plastics applications, such as packaging, paneling, medical equipment and more. New technologies aren’t necessarily needed, so companies and manufacturers do not have any reservations about its viability as an industry.

Here are a few types of bioplastics derived from hemp:

  1. Hemp Cellulose-based Bioplastics

This is a substance found in plant cell walls. We use cellulose to manufacture a broad range of unique plastics, including celluloid, rayon and cellophane. These plastics are usually entirely organic. We mix cellulose and its variations (such as nanocellulose, made from cellulose nanocrystals) with other ingredients, such as camphor, to produce thermoplastics and the like. Using natural polymer, we process a broad range of bioplastics and corresponding polymers. The difference in their chemical properties is down to the nature of the polymer chains and the extent of crystallization.

  1. Composite Hemp-based Bioplastics

Composite plastics comprise organic polymers like hemp cellulose, as well as an addition of synthetic polymers. They also have reinforcement fibers to improve the strength of the bioplastic, which are also either organic or synthetic. Sometimes, we blend hemp cellulose with other organic polymers like shellac and tree resins. Inorganic fillers include fiberglass, talc and mica.

We call any natural polymer, when blended with synthetic polymers, a “bio composite” plastic. We measure and calibrate these ingredients according to the desired stiffness, strength and density of the eventual plastic product. Apart from packaging, manufacturers use these bioplastics for furniture, car panels, building materials and biodegradable bags.

A composite of polypropylene (PP), reinforced with natural hemp fibers, showed that hemp has a tensile strength akin to that of conventional fiberglass composites. Furthermore, malleated polypropylene (MAPP) composites, fortified with hemp fibers, significantly improved stress-enduring properties compared to conventional fiberglass composites.

  1. Pure Organic Bioplastics With Hemp

We have already generated several bioplastics entirely from natural plant substances like hemp. Hemp fibers, when made alkaline with diluted sodium hydroxide in low concentrations, exhibit superior tensile strength. We have produced materials from polylactic acid (PLA) fortified with hemp fibers. These plastic materials showed superior strength than ones containing only PLA. For heavy-duty packaging, manufacturers use hemp fibers reinforced with biopolyhydroxybutyrate (BHP), which are sturdy enough.

With the world in a state of major change due to the coronavirus outbreak of 2020, the focus is back on packaging and delivery. In this volatile area, perhaps the industry can learn a few new tricks, instead of suffocating itself in old traditions and superficial opportunism. The permutations and combinations of bioplastic technology can serve a swath of packaging applications. We must thoroughly explore this technology.

Hemp’s Future in Packaging

Fossil fuel-based plastic polymers are non-renewable, highly pollutive and dangerous to ecosystems, due to their lifespans. They are some of the most destructive inventions of man, but thankfully could be held back by this crop. Industrial hemp upheld countless industries through human history and now is making a comeback. After existing in relative obscurity in the U.S. due to false connotations with the psychoactive properties of its cousin, it is now back in business.

With the American hemp industry on the verge of a revolution, hemp packaging is primed to take over a significant part of the global packaging sector. The political, economic and environmental incentives for companies to adopt bioplastics are legion. Its lower cost lends to its allure as well. Consumers and agribusinesses are following suit, making the choice to be environmentally-conscious. By 2030, it is estimated that 40% of the plastics industry will be bioplastics.

We can only mitigate the plastic pollution in oceans, landfills and elsewhere, with the use of biodegradable bioplastics; otherwise, animals, humans and plants are getting adversely affected by imperceptible microplastics that pervade vast regions of the Earth. With hemp bioplastics, we use the cleaner, renewable matter of plants to conserve the planet’s sanctity. We can expect this new technology to continue to light the way for other nations, societies and companies to build upon this sustainable plan.

USDA Announces Risk Management Programs for Hemp

By Aaron G. Biros

According to a press release published earlier this month, the U.S. Department of Agriculture (USDA) announced two new programs available for hemp growers to mitigate their risk.

The first is called Multi-Peril Crop Insurance (MPCI), which is a pilot hemp insurance program designed to cover against “loss of yield because of insurable causes of loss for hemp grown for fiber, grain or Cannabidiol (CBD) oil.” The second plan is Noninsured Crop Disaster Assistance Program, which protects against losses from lower-than-normal yields, destroyed crops or “prevented planting” where permanent crop insurance is not available.

Both of the programs are now accepting applications and the deadline to apply is March 16, 2020. “We are pleased to offer these coverages to hemp producers. Hemp offers new economic opportunities for our farmers, and they are anxious for a way to protect their product in the event of a natural disaster,” says Bill Northey, Farm Production and Conservation Undersecretary.

The MCPI program is available for hemp producers in 21 states, according to the press release. Th program is available in certain counties in Alabama, California, Colorado, Illinois, Indiana, Kansas, Kentucky, Maine, Michigan, Minnesota, Montana, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Oregon, Pennsylvania, Tennessee, Virginia and Wisconsin.

There are a handful of requirements to be eligible for that program, such as having one year of growing under their belt and have contracts in place for the sale of their crops. Hemp growers producing CBD must have at least 5 acres and hemp growers producing fiber must have at least 20 acres cultivated.

In 2021, the press release states, “hemp will be insurable under the Nursery crop insurance program and the Nursery Value Select pilot crop insurance program.” With those programs, hemp crops can be insured if grown in containers and in accordance with federal law.

To apply for any of these programs, hemp growers must have a license and must be totally compliant with state, tribal or federal regulations, or be operating under a state or university research plot from the 2014 Farm Bill. Growers need to report their hemp acreage to the Farm Service Agency, a division of the USDA.

The press release also mentions that if the crops have above 0.3% THC, the crop becomes uninsurable and ineligible for any of the programs.

Preventing Mold & Fungus in Cannabis with Data Analytics

By Leighton Wolffe
No Comments

Cannabis legalization has taken the United States by storm, with 33 states approved for medicinal cannabis use — 11 of which are also approved for recreational use for adults aged 21 and over. With new patients and consumers entering the market every day, it’s more important than ever for cannabis cultivators to establish more effective methods for mold and fungal prevention in their crops and to ensure consumer confidence in their brands.

Today, many cultivators address the risk of mold and fungus growth by testing crops for contaminants at the end stage of production. While this helps to catch some infected product before it reaches the market, this method is largely ineffective for mold and fungal prevention during the cultivation process. In fact, recent studies have shown an 80% failure rate in mold and fungal testing in Denver cannabis dispensaries. By relying on late-stage, pass/fail testing, cannabis entrepreneurs also expose themselves to increased risk of lost crops and profits.

However, emerging sensor technologies exist that can test plants during the grow process, significantly reducing the risks associated with cannabis cultivation while increasing the bottom line for commercial grow operations. By leveraging data from these monitoring sensors along with environmental automation systems that are integrated with data analytics platforms, cannabis professionals can take a proactive approach to achieve the ideal environmental conditions for their crops and prevent against mold and fungal infestation.

Common Causes for Bud Rot in Indoor Growing Systems 

Botrytis cinerea — commonly known as “bud rot” — is a pathogenic fungi species that creates a gray mold infection in cannabis plants. An air-borne contaminant, it is among the most prevalent diseases affecting marijuana crops today and can lead to significant damages, particularly when left untreated during post-harvest storage. Bud rot is one of the most difficult challenges cannabis entrepreneurs face: Once plants have been affected, only 2% can be expected to recover. This is because Botrytis cinerea can use multiple methods for attacking host plants, including using the plant’s natural defenses against it to continue infestation.

While difficult to contain, bud rot is very easy to spot. Plants affected with the fungus will begin yellowing, experience impaired growth, and develop gray fungus around its buds. Overall crop yield will be significantly reduced, leading to decreased profit for cannabis cultivators. The biggest contributing factors to a Botrytis cinerea infestation are as follows:

  • Humidity: Indoor grow facilities that maintain humidity levels in excess of 45% are breeding grounds for mold and fungus. These environments can become perfect conditions for mold and fungal growth.
  • Temperature: Bud rot typically thrives in environments where temperatures fall between 65- and 75-degrees Fahrenheit, which is why greenhouses and grow rooms are often the victim of such infestations.
  • Ventilation: Poor airflow is another contributing factor to Botrytis cinerea Without proper ventilation, excess moisture buildup will eventually result in mold and mildew growth.
  • Strain: Some marijuana strains are better equipped to fend off bud rot infection. In particular, sativa plants have a higher resistance to mold development than their C. indica and C. ruderalis cousins.

Controlling mold and fungal growth in commercial grow facilities is a top priority for cannabis cultivators. Not only detrimental to their profitability and crop yield, infected plants can pose serious health risks to consumers, especially for immunocompromised patients. Consuming cannabis products that have been compromised by bud rot or other mold and fungal infections can cause a wide range of medical concerns, including pneumonitis, bronchitis, and other pulmonary diseases. As a result, growers are required to dispose of all infected plants without the possibility to sell.

Bud rot isn’t the only culprit responsible for cannabis plant destruction. Powdery mildew, Fusarium, sooty molds, and Pythium all contribute to the challenges faced by cannabis professionals. In fact, a recent study conducted by Steep Hill Labs and University of California, Davis – Medical Center found that in 20 randomly-selected samples submitted for testing, all samples showed detectable levels of microbial contamination7. Many of these samples also contained significant pathogenic microorganism contamination. Without proper detection and prevention methods in place, these pesky plant-killers will only continue to terrorize the cannabis cultivation industry.

The Current Cannabis Cultivation Landscape 

The data is clear: Current practices for cannabis cultivation are insufficient for preventing against mold and fungal growth. Sterilization and pass/fail testing do not identify the root cause of harmful infestations in plants, therefore leaving cannabis professionals in the dark about how to better optimize their grow conditions for improved crop reliability and safety. In order to prevent against damages incurred from mold and fungal infestation, marijuana growers must be more diligent in their grow condition monitoring practices.

Many cannabis professionals rely on manual monitoring to identify environmental changes within their indoor grow facilities. While it’s important to collect data on your operation’s essential systems, doing so without the right tools can be time-consuming and ineffective. Manual monitoring often relies on past data and does not illustrate the relationship between different systems and their impact on environmental changes. The goal is to assemble data from all the grow systems and create correlations on actual bio-environmental conditions during the grow process to compare to yield results. This is only available when an information management platform is synthesizing data from all the systems within the grow facility and presenting meaningful information to the growers, facility operators and owners.

Especially as the cannabis industry is expected to grow exponentially in coming years, growers need more robust tools for tracking and manipulating environmental changes within their indoor growing systems.

Leveraging Building Automation Systems & Data Analytics in Cannabis Cultivation 

A powerful approach to prevent environmental conditions that are known to lead to mold and fungus growth exists in leveraging the data produced from your grow facility’s various automation systems. Most commercial cultivation facilities have multiple stand-alone and proprietary systems to control their indoor environment, making it difficult to not only collect all of this valuable data, but also to achieve the level of grow condition monitoring necessary for mold and fungal prevention.

With some data analytics platforms, such as GrowFit Analytics, data is collected across disparate systems that don’t normally communicate with one another, providing access to the key insights necessary for achieving environmental perfection with your cannabis crops. A viable solution collects vital grow facility system data and relevant bio-environmental monitoring data, and delivers this information in one, centralized software interface. The software then will apply analytic algorithms to develop key performance indicators (KPIs) while working to detect system anomalies, faults, and environmental fluctuations. The right analytics solution should also be customizable, allowing you to track the KPIs that are most important to your unique facility, and to achieve the vision of your chief grower. Ultimately, the software should serve up actionable insights that empower facility management and growers.

Collecting reliable data from different grow facility systems and environmental sensors can be a complex process and the information collected illustrates more than just what’s working right and what isn’t. By implementing an advanced data analytics solution, cannabis cultivation professionals can now be empowered to track minute details about their indoor grow facility, providing a safer, healthier environment for their crops and avoiding those environmental conditions that lead to mold and fungus altogether.

An ideal data analytics platform won’t simply collect data to be analyzed at a later date, and simple trending of sensor data is not enough. Information — especially in a commercial grow facility — is time-sensitive, which is why growers should select a system that offers real-time analytics capabilities. Some platforms offering real-time analytics utilize cloud computing, allowing for easy access from anywhere while also providing enhanced security to protect sensitive facility data. The most robust data analytics platforms provide detailed historical data for your entire crop’s lifecycle that provide a “digital recipe” to replicate successful crops, and fine-tune the process for continuous improvement.

Data analytics tools can also impact the bottom line by lowering operational costs. GrowFit Analytics, for example, was born out of a software solution designed to lower energy costs for large complex buildings like commercial grow facilities.

The data and insights provided can help identify opportunities for greater energy efficiency, which can lead to significant utility savings. Grow facilities operate 24 hours/day, with energy expenses representing one of the largest operational costs. With data analytics tools at their disposal, facility managers are armed with the information they need to improve system efficiency, increase energy savings, and improve profitability.

How to Grow Cannabis Plants for Concentrate Production

While flower is still the most popular way to consume cannabis, the concentrates market is booming. Some predict concentrates will be nearly as popular as flower by 2022, with an estimated $8.5 billion in retail sales. That’s a lot of concentrates and, chances are, cannabis producers are already feeling the pressure to keep up.

Concentrates refer to products made from processing cannabis – often resulting in much higher THC or CBD percentages. The category includes oils, wax, dabs, shatter, live resin and hash. Consumers are increasingly drawn to these cannabis products for their near-immediate and intense effects. They’re often consumed through vaporization, dabbing or sublingual absorption and are sometimes favored by those who want to avoid smoking. Cannabis growers who have traditionally focused on flower yields may decide to prioritize quality and potency levels in order to tap into these changing consumer tastes.

What Growers Should Focus on to Produce High Quality Concentrates
We’ll let you in on a little secret: making good concentrates starts with good flower. If you’re starting with low-quality flower, it’s impossible to create a high-quality concentrate. Whatever qualities inherent to the flower you’re starting with will be amplified post-processing. So, really, the concentrate-making process starts at the seedling level, requiring the right care and attention to coax out the results you’re looking for.

Tetrahydrocannabinol (THC), just one of hundreds of cannabinoids found in cannabis.

But what makes good flower? While this can be a subjective question, those producing concentrates generally look for flowers with big, abundant trichomes. Trichomes are the small, dewy structures found across the cannabis plant on buds, leaves and even the stem. They’re responsible for producing the plant’s cannabinoids and terpenes – the chemical compounds that give a strain its unique benefits, aroma and taste. Evolutionarily, trichomes attract pollinators, deter hungry herbivores and provide some defense against wind, cold and UV radiation.

Generally, trichomes indicate how potent the flower is. Plus, what we’re most often looking for when making concentrates is higher cannabinoid and terpene profiles, while also ensuring absolute safety.

What measures can growers take to produce crops that are ideal for concentrate production? Start with the following:

Avoiding Contaminants
Just like you would wash your fruits and vegetables before consumption, consumers want to be sure there’s no dangerous residuals in the concentrate they are ingesting. Growers can avoid any post-process residuals by taking a few key steps, including:

    Cutting out the pesticides. Any pesticides that are on your flowers before they go through processing will show up in your concentrates, often even more – you guessed it – concentrated. This is a serious health concern for consumers who might be sensitive to certain chemicals or have compromised immune systems. It’s dangerous to healthy consumers, too. Rather than spraying hazardous chemicals, growers could consider integrated pest management techniques, such as releasing predatory insects.

  • Limiting foliar spraying. Some growers will use foliar spraying to address nutrient deficiency or pest-related issues through delivering nutrients straight to the leaves. However, this can also result in contaminated concentrates. If you really need to spray, do it during the vegetative stage or investigate organic options.
  • Taking the time to flush the crop. This is a critical step in reducing potential contaminants in your concentrate, especially if you’re using a non-organic nutrient solution or fertilizer. Flushing simply means only giving your plants water during the final two weeks of flowering before harvest, resulting in a cleaner, non-contaminated flower and therefore a cleaner concentrate.

Perfecting the Indoor Environment
When cultivating cannabis indoors, growers are given ultimate control over their crop. They control how much light the plants receive, the lighting schedule, temperature and humidity levels. Creating the ideal environment for your cannabis crop is the number one way to ensure healthy plants and quality concentrates. There are many factors to consider when maintaining an indoor grow:

  • Temperature regulation. Trichomes are sensitive to temperature changes and start to degrade if they’re too hot or too cold. To maintain the best trichome structure, you’ll want to maintain an ideal temperature – for most strains, this falls between an idyllic 68 and 77 degrees.
  • Adequate light. For plants to perform photosynthesis indoors, they’ll need an appropriate light source – preferably one that is full-spectrum. Full-spectrum LEDs are able to closely replicate the sun and provide ample, uniform light to your crop. Another selling point for LEDs is their low heat output, making it much easier for growers to regulate ambient heat.

  • CO2. Another necessary ingredient for photosynthesis is CO2. Providing your indoor crops with CO2 can boost plant size and yields and, therefore, provides more surface area for trichomes to develop and thrive.
  • Cold snap prior to harvest. Some growers rely on this age-old tactic for one last push before harvest – lowering their temperature for a few days right at the end of the flower cycle. They believe this puts the plants into a defense mode and will produce more trichomes in order to protect themselves.

Following Best Practices Post-Harvest
You made it to harvest – you’re almost done!

When harvesting and storing your plants, handle them with care to reduce damage to trichomes. If you’re planning on immediately making concentrates, you can move forward to the drying and curing process. If you’re going to wait a few weeks before processing, freeze your plants. This will preserve the cannabinoid and terpene profiles at their peak.

As the cannabis industry continues to expand, more consumers are likely to reach for concentrates at their local dispensaries. It makes sense that businesses want to diversify their offerings to satisfy customers looking for the most effective way to consume cannabis. As with any cannabis-derived product, producers will want to prioritize quality and safety – especially in the concentrate market.

Cannabis Industry Insurance Outlook for 2020

By , T.J. Frost

Cannabis businesses have a lot to look forward to in 2020. After a bipartisan push through the House, the Safe Banking Act currently awaits passage in the Senate and then the president’s signature. If all goes well, the bill will allow the financial sector to finally service cannabis businesses – from banking to investments and insurance.

What else can cannabis business look forward to this year? Check out HUB’s Top 5 cannabis industry predictions for 2020.

  1. Hemp/CBD products go to market in droves. The passage of the Farm Bill and the ease of shipping hemp across state lines has led to a production boom for the crop. With little federal regulation around manufacturing and distribution, hemp/CBD products from edible oils to clothing and anti-inflammatory lotions are extremely profitable. Expect final federal Domestic Hemp Production Program rules on acceptable levels of THC in hemp/CBD products to be published sometime in 2020. These will be based on the current rule draft. There’s a strong push to move industrial hemp into the federal crop insurance program, which is also likely to happen in 2020.
  2. Product liability insurance is no longer a luxury. Thanks to significant vaporizer, battery and contamination claims currently in the courts, cannabis business can expect higher product liability premium rates in 2020. Expect rates to jump as much as 30 to 40%, depending on the resolution of these cases. For this reason, carriers will be more diligent about underwriting and may even ask for certification of insurance from vendors, and additional insureds on third-party policies. Exercising more caution and oversight when selecting vendors is a must for cannabis businesses operating in 2020 under this premise. It’s critical for all organizations to take a hard look at business practices before entering partnerships moving forward.
  3. Phase II industry growing pains surface. Now that the cannabis gold rush is dying down, businesses are poised to enter Phase II of their growth.Those who failed to institute proper hiring processes, including background checks, as well as protocols to promote security and prevent theft are currently facing challenges. Significant industry consolidation is making way for cannabis conglomerates to become multi-state operators. Directors and officers that made poor investments or acquisitions are facing scrutiny at the hands of the SEC or business investors. Without D&O insurance, or adequate limits, directors and officers could find their personal finances drained. Insisting on adequate D&O protection going forward is a best practice for cannabis executives.  
  4. Product and state regulatory testing expands. High-profile manufacturers and distributors of cannabis are standardizing their cannabis, hemp and CBD ingredient labeling. However, many others are taking advantage of the lack of rules currently surrounding cannabis production by falsifying labels and misrepresenting THC content in products. This has led to recent lawsuits and claims. As a result, states will begin to administer product testing and license regulations and enforce carrying time limits, track and trace and bag and tag rules. Get ready for fines, penalties and increased non-compliance liabilities in 2020.
  5. Increased availability of policies and limits. Both the cannabis industry and the number of insurance carriers entering the market continue to grow steadily. Businesses are enjoying higher liability limits as a result – to the tune of $15M on product liability and $60M on property. Coverage for outdoor cannabis crop is now a possibility, and workers’ compensation coverage can function as a blanket policy for businesses across state lines as well. Should the Safe Banking Act pass soon, stay tuned for additional insurance opportunities as well.

2020 Growth and Beyond

The 2020 presidential election will bring the federal legalization of cannabis to the forefront of public discourse. While the law may not change yet, passage of the Safe Banking Act and increased regulatory action at the state level will highlight the successes and failures of the 33 states and the District of Columbia that have legalized cannabis in some capacity. These will serve as a guiding light for federal legalization down the road.

This morning, U.S. Secretary of Agriculture Sonny Perdue announced the establishment of the U.S. Domestic Hemp Production Program. The program, as stipulated by Congress in the 2018 Farm Bill, will establish a regulatory framework for hemp production in the country.

Secretary Perdue made the announcement in a YouTube video titled “USDA’s Hemp Policy.” Later in the week, an interim final rule formalizing the program will be published in the Federal Register, according to the USDA’s website. “The rule includes provisions for the U.S. Department of Agriculture (USDA) to approve hemp production plans developed by states and Indian tribes including: requirements for maintaining information on the land where hemp is produced; testing the levels of delta-9 tetrahydrocannabinol; disposing of plants not meeting necessary requirements; and licensing requirements,” reads the press release. “It also establishes a federal plan for hemp producers in states or territories of Indian tribes that do not have their own approved hemp production plan.” The interim final rule will go into effect as soon as it is published in the Federal Register, which should be by the end of this week.

You can find a preview of the rule here. The agency has also developed guidelines for sampling and testing procedures, which you can find here. Those documents are meant to provide more information for hemp testing laboratories.

You can watch the YouTube video and read the announcement he made below:

Hello everyone, as I travel across this great country of ours, I hear a lot about a strong interest in a new economic opportunity for America’s farmers: the production of hemp. Which is why today I am pleased to announce the USDA has published the rule establishing the US domestic hemp production program. We said we’d get it done in time for producers to make planning decisions for 2020 and we followed through. We have had teams operating with all hands-on-deck to develop a regulatory framework that meets Congressional intent while seeking to provide a fair, consistent and science-based process for states, tribes, and individual producers who want to participate in this program. As mandated by Congress, our program requires all hemp growers to be licensed and includes testing protocols to ensure that hemp grown under this program is hemp and nothing else. The USDA has also worked to provide licensed growers access to loans and risk management products available for other crops. As the interim final rule, the rule becomes effective immediately upon publication in the federal register. But we still want to hear from you. Help us make sure the regulations meet your needs. That’s why the publication of the interim final rule also includes a public comment period continuing a full and transparent rulemaking process that started with a hemp listening session all the way back in March 2019. At USDA, we are always excited when there are new economic opportunities for our farmers and we hope the ability to grow hemp will pave the way for new products and markets. And I encourage all producers to take the time to fully educate themselves on the processes, requirements and risk that come with any market or product before entering this new frontier. The Agricultural Marketing Service will be providing additional information, resources and educational opportunities on the new program. And I encourage you to visit the USDA hemp website for more information. As always, we thank you for your patience and input during this process.

The Best Way to Remediate Moldy Cannabis is No Remediation at All

By Ingo Mueller

Consumers are largely unaware that most commercial cannabis grown today undergoes some form of decontamination to treat the industry’s growing problem of mold, yeast and other microbial pathogens. As more cannabis brands fail regulatory testing for contaminants, businesses are increasingly turning to radiation, ozone gas, hydrogen peroxide or other damaging remediation methods to ensure compliance and avoid product recalls. It has made cannabis cultivation and extraction more challenging and more expensive than ever, not to mention inflaming the industry’s ongoing supply problem.

The problem is only going to get worse as states like Nevada and California are beginning to implement more regulations including even tougher microbial contamination limits. The technological and economic burdens are becoming too much for some cultivators, driving some of them out of business. It’s also putting an even greater strain on them to meet product demand.

It’s critical that the industry establishes new product standards to reassure consumers that the cannabis products they buy are safe. But it is even more critical that the industry look beyond traditional agricultural remediation methods to solve the microbial problems.

Compounding Risks

Mold and other microbial pathogens are found everywhere in the environment, including the air, food and water that people consume. While there is no consensus yet on the health consequences of consuming these contaminants through cannabis, risks are certainly emerging. According to a 2015 study by the Cannabis Safety Institutei, molds are generally harmless in the environment, but some may present a health threat when inhaled, particularly to immunocompromised individuals. Mycotoxins resulting from molds such as Aspergillus can cause illnesses such as allergic bronchopulmonary aspergillosis. Even when killed with treatment, the dead pathogens could trigger allergies or asthma.

There is an abundance of pathogens that can affect cannabis cultivation, but the most common types are Botrytis (bud rot, sometimes called gray mold) and Powdery Mildew. They are also among the most devastating blights to cannabis crops. Numerous chemical controls are available to help prevent or stem an outbreak, ranging from fungicides and horticultural oils to bicarbonates and biological controls. While these controls may save an otherwise doomed crop, they introduce their own potential health risks through the overexposure and consumption of chemical residues.

The issue is further compounded by the fact that the states in which cannabis is legal can’t agree on which microbial pathogens to test for, nor how to test. Colorado, for instance, requires only three pathogen tests (for salmonella, E. coli, and mycotoxins from mold), while Massachusetts has exceedingly strict testing regulations for clean products. Massachusetts-based testing lab, ProVerde Laboratories, reports that approximately 30% of the cannabis flowers it tests have some kind of mold or yeast contamination.

If a cannabis product fails required microbial testing and can’t be remedied in a compliant way, the grower will inevitably experience a severe – and potentially crippling – financial hit to a lost crop. Willow Industries, a microbial remediation company, says that cannabis microbial contamination is projected to be a $3 billion problem by 2020ii.

Remediation Falls Short
With the financial stakes so high, the cannabis industry has taken cues from the food industry and adopted a variety of ways to remediate cannabis harvests contaminated with pathogens. Ketch DeGabrielle of Qloris Consulting spent two years studying cannabis microbial remediation methods and summarized their pros and consiii.

He found that some common sterilization approaches like autoclaves, steam and dry heat are impractical for cannabis due the decarboxylation and harsh damage they inflict on the product. Some growers spray or immerse cannabis flowers in hydrogen peroxide, but the resulting moisture can actually cause more spores to germinate, while the chemical reduces the terpene content in the flowers.

Powdery mildew starts with white/grey spots seen on the upper leaves surface

The more favored, technologically advanced remediation approaches include ozone or similar gas treatment, which is relatively inexpensive and treats the entire plant. However, it’s difficult to gas products on a large scale, and gas results in terpene loss. Microwaves can kill pathogens effectively through cellular rupture, but can burn the product. Ionizing radiation kills microbial life by destroying their DNA, but the process can create carcinogenic chemical compounds and harmful free radicals. Radio frequency (which DeGabrielle considers the best method) effectively kills yeast and mold by oscillating the water in them, but it can result in moisture and terpene loss.

The bottom line: no remediation method is perfect. Prevention of microbial contamination is a better approach. But all three conventional approaches to cannabis cultivation – outdoors, greenhouses and indoor grow operations – make it extremely difficult to control contamination. Mold spores can easily gain a foothold both indoors and out through air, water, food and human contact, quickly spreading into an epidemic.

The industry needs to establish new quality standards for product purity and employ new growing practices to meet them. Advanced technologies can help create near perfect growing ecosystems and microclimates for growing cannabis free of mold contamination. Internet of Things sensors combined with AI-driven robotics and automation can dramatically reduce human intervention in the growing process, along with human-induced contamination. Natural sunlight supplemented with new lighting technologies that provide near full-light and UV spectrum can stimulate robust growth more resistant to disease. Computational fluid dynamic models can help growers achieve optimal temperature, humidity, velocity, filtration and sanitation of air flow. And tissue culture micropropagation of plant stock can eliminate virus and pathogen threats, to name just a few of the latest innovations.

Growing legal cannabis today is a risky business that can cost growers millions of dollars if pathogens contaminate a crop. Remediation methods to remove microbial contamination may work to varying degrees, but they introduce another set of problems that can impact consumer health and comprise product quality.
