The Distressed Cannabis Business: An Alternative to Bankruptcy

By Paula Durham, Scott E. Evans

Bankruptcy is Not an Option

Bankruptcy courts do not provide protection to cannabis and cannabis-related businesses.Bankruptcy can be a very helpful tool for a distressed business. Bankruptcy allows a business to stop collection actions, discharge certain debts, cancel unfavorable contracts and provides breathing room to restructure the business.

What if your cannabis operation is struggling or failing – file for bankruptcy, right? Not so fast. Despite cannabis being legalized or decriminalized for certain activities at the state level, it remains illegal at the federal level. Therefore, the bankruptcy court will not provide protection to cannabis and cannabis-related businesses (CRB).

Alternatives to Bankruptcy

A State Court receiver may be the best alternative when bankruptcy is not an option.Enter the state court receivership. Receivership is an equitable remedy that is often employed as an alternative to a bankruptcy proceeding. A receivership can address business insolvency or can be a temporary remedy during legal proceedings between disputing business partners, with control of the enterprise hanging in the balance.

In either scenario, the court appointed receiver takes control of the business and must assess the posture of the business and determine the best path forward. The receiver’s options run the gamut from operating the company as is, restructuring operations to maximize profit or closing shop and liquidating the business as a whole or in pieces. The receiver has a fiduciary responsibility to determine the option that best satisfies creditors, similar to duties required of a trustee in a bankruptcy.

The importance of having a receiver well-versed in the cannabis industry cannot be overstated.Distressed cannabis companies are often prime candidates for receivership. Cannabis is a burgeoning industry with huge growth and profit potential. However, worlds have collided in the Green Rush, where business-minded individuals, often with little knowledge of cannabis, have partnered with individuals well-versed in cannabis culture, cultivation and consumption, but with little experience operating a business. Add a dash of complex state laws and regulatory drama in the form of the federal/state divide on legality, a dollop of fraud potential due to the largely all-cash nature of the business and you’ve created the perfect recipe for insolvency, litigation or both. In these often-chaotic conditions it is easy for a cannabis company to become unprofitable. A receiver can add significant value by stabilizing the business while the litigation proceeds or while developing a restructuring plan. In either case the goal of a receivership is to maximize the value of a business for the benefit of its stakeholders.

If you are considering restructuring options for your cannabis operation, a receivership can be an excellent choice. However, a cannabis receivership is not for the faint of heart. There are two significant areas that distinguish cannabis receiverships from receiverships involving non-cannabis businesses: First, the complex regulatory environment and second, banking. The importance of having a receiver well-versed in the cannabis industry cannot be overstated. Making a mistake in these areas can cause more harm than good.

Complex Regulatory Environment

Cannabis operations are subject to a complicated regulatory framework that varies by state as well as by type of legalization (medical versus adult use cannabis). Receivers unfamiliar with the cannabis industry and the associated regulatory framework will be behind the curve on day one.

Upon appointment over a cannabis entity a receiver becomes responsible for the regulatory posture of that entity.Regulatory hurdles begin at the outset of a receivership. Although receivership is an excellent restructuring option for cannabis operators in distress, regulations surrounding the authorization requirements for those operating the business on a day-to-day basis (including receivers) vary by state. Some states, but not all, even have specific regulations for receiverships.

For example, the rules and regulations for cannabis operators in Colorado administered by the Colorado Marijuana Enforcement Division (MED) include provisions for receiverships. Specifically, the MED requires court appointees, including receivers, to register with the State Licensing Authority as Temporary Appointee[s] of the Court within seven days of appointment.

Similarly, Washington State cannabis regulations directly address receiverships. Specifically, Title 314 allows receivers or trustees to operate a licensed cannabis business, but the receiver must be qualified by the Washington State Liquor Control Board (LCB). Qualification requirements include active status on the LCB preapproved receiver list or submission of an application to serve as a receiver for a licensee within two days of appointment. Furthermore, to serve as a receiver of a Washington state cannabis licensee the receiver must meet residency requirements.

Conversely, the Arizona cannabis laws and rules do not specifically address cannabis receiverships. Nevertheless, Arizona does require anyone volunteering or working at a medical or recreational cannabis dispensary to be registered with the Arizona Department of Health Services as either a Dispensary Agent (DA) or a Facility Agent (FA). Therefore, a receiver appointed over a licensed cannabis business in Arizona must obtain the applicable registration upon appointment in order to take control of the licensed entity in a compliant manner.

The fun doesn’t stop after the initial appointment hurdles are cleared. The regulatory environment across the country is a patchwork of complex laws. States that have legalized or decriminalized cannabis on some level have instituted often complex rules surrounding the cultivation, manufacture, wholesale and retail sale of cannabis. Even seemingly simple concepts such as the definition of cannabis are not so simple in some states. For example, Massachusetts includes cannabidiol (CBD) in its definition of cannabis while Arizona does not.

Some states, like California, do not allow the sale of cannabis licenses. Other states, like Colorado, allow for the transfer of commercial cannabis licenses. In a turnaround situation it is particularly important to understand the options available to liquidate a licensee’s assets.

Similarly, many, but not all states have rules requiring cannabis product testing by accredited laboratories prior to retail sale. Most states require THC potency testing, while others (like California and Colorado) also require testing for pesticides and toxins. Conversely, testing for toxins and contaminates is voluntary in Florida. Product testing is expensive and time-consuming, and operators must have a comprehensive system in place to ensure compliant product is available for sale to retail and wholesale customers.

Even taxes are different for cannabis businesses. A receiver must understand and be able to manage a cannabis business in order to comply with and minimize taxes under the infamous 280e regulations of the U.S. tax code.

Upon appointment over a cannabis entity a receiver becomes responsible for the regulatory posture of that entity. Accordingly, the receiver must ensure that any regulatory deficiencies are identified and corrected in order to ensure compliant operation.

We’ve highlighted just a few of the myriad of regulatory concerns facing a receiver upon appointment. It is critical to engage a receiver who has experience working under the complex cannabis regulatory structure for your distressed cannabis operation.

Banking

One of the most important things a receiver does upon appointment is to identify and secure the assets of the entity in receivership, including cash. This normally involves opening a bank account in the name of the receivership entity that is controlled solely by the receiver and moving cash assets into the controlled account.

This typically ordinary task is not so easy with a cannabis operation. Because cannabis remains illegal under federal law, processing funds derived from the sale of cannabis (even sales that are legal at the state level) can be considered by the Department of Justice (DOJ) as aiding and abetting criminal activity or money laundering.A receiver must negotiate the complex banking regulations regarding cannabis businesses and effectively manage the large amounts of cash, which may not be bankable.

The Financial Crimes Enforcement Network (FinCen) issued guidance in 2014 that cleared the way for financial institutions to service canna-businesses (2014 Guidance). The 2014 Guidance requires financial institutions who choose to provide services to CRBs to design and implement a thorough customer due diligence review that includes, in part, analyzing the licensing of the entity, developing an understanding of the business operations of the entity, and ongoing monitoring of the entity. In addition, financial institutions are required to file a Suspicious Activity Report (SAR) for every transaction they process for a CRB, should they choose to accept the business.

While this is a positive step forward, it is a heavy compliance burden that comes at a cost. Naturally, compliance costs incurred by banks to service cannabis operators are passed on to the customer; fees of $2,500 per month per account are not uncommon. The high compliance costs, coupled with the significant regulatory risk, keeps most banks out of the cannabis market; thus, making it hard, but not impossible, for a receiver appointed over a cannabis operation or CRB to obtain banking.

While banking options do exist, the reality is that most canna-businesses operate on a cash basis. Distressed cannabis operations may not have the cashflow to afford banking services, at least at the outset of a receivership. Further compounding the banking problem, some banks that are open to cannabis are not open to receiverships, further limiting banking options.

A receiver therefore must be prepared to quickly secure all cash assets of the receivership entity and ensure appropriate internal controls are in place to control cash on an ongoing basis.

Cannabis has been legalized or decriminalized in a majority of U.S. states but remains illegal at the federal level. Therefore, federal bankruptcy protection is not generally an option available for a distressed canna business. However, not all is lost because state receiverships offer an excellent restructuring option for distressed cannabis operations.

An Inside Look at the Creation and Growing Popularity of Solventless Cannabis Products

By Tim Nolan

No Comments

A top product trend this year is the rise of solventless cannabis products, according to recent statistics from cannabis market analyst firm BDSA. In fact, from June 2021 to June 2022, BDSA research also showed that the category grew an average of 132% each month.

Nearly all cannabis products start with cannabis concentrates, which are made with a solvent that contains the desirable compounds from cannabis. Solventless concentrates however are made from the cannabis flower without the use of any chemicals and are becoming popular among businesses and consumers. This broad category of cannabis products includes everything from hash to live rosin.

Mitch Lindback, Lab Director at Copperstate Farms, has been growing and extracting cannabis for 15 years and has over a decade of experience working with cannabis derivatives. “Solventless is the truest expression of the cannabis plant,” he says.

Copperstate Farms is one of the largest greenhouse cannabis producers in North America and home to 1.7 million square feet of canopy and 40 acres under glass. Here is an inside look into the company’s solventless creation process:

The Harvest

One of the most important growth factors in cannabis is light, so cannabis grown in full-spectrum light often brings the best flower to harvest. In the weeks before harvesting, the lab conducts a test wash on cannabis plants before hand-selecting which will be used in rosin. Plants are selected based on appearance, aroma and test wash results. On harvest day, all flowers are lightly hand-trimmed and frozen within two hours of harvest.

The Wash

Using only chilled RO water and minimal ice, our cannabis extraction experts gently break the trichome heads off the fresh-frozen cannabis using a stainless-steel wash system, by gently agitating the flower. Then they collect the 73μ-159μ trichome heads while pushing the immature trichome heads and stalks to pass through collection bags with a cold spray wash.

The Press

After carefully freeze drying, sifting and packing the hash into double-wrapped mesh rosin bags, Copperstate Farms uses rosin presses to gently express the nectar from the trichome heads using a little heat and a lot of pressure.

The Cure

All live rosin goes through a minimum 7-day cure. “We have found through extensive analytical testing that curing rosin for a minimum of seven days increased its terpene content by over 30 percent,” Lindback says.

The extensive process to create solventless cannabis products is time and energy intensive, but leads to quality offerings, like full melt hash and live rosin. In fact, the solventless category is “primed for premiumization and growth in legal cannabis markets,” according to BDSA retail sales analytics. This is especially true in the dabbable concentrate product category and predicted in the vaping concentrate category as well.

With popular annual holidays like 7/10 (the cannabis community’s holiday for celebrating oil products, dabs and concentrates) gaining traction, solventless products are predicted to grow in market share and are worth cannabis companies looking into producing as demand rises among consumers who are always looking for innovative products that feature solventless concentrate.

Minnesota Legalizes Adult Use Cannabis: Part 2

By Abraham Finberg, Rachel Wright, Simon Menkes

No Comments

In Part 1, we examined the current status of adult use cannabis in Minnesota, paying particular attention to the licensing framework, taxation and social equity considerations. In this article, we’ll cover some important need-to-know info if you’re considering opening an adult use business in the “Land of 10,000 Lakes.”

Starting a Cannabis Business in Minnesota: Important Considerations

As the state does not expect to begin issuing licenses before the first quarter of 2025, now is the time to plan a licensing campaign. With a population of 5,714,000, 64% of which live in the Twin Cities of Minneapolis-Saint Paul, Minnesota is close in population to Colorado, with 5,774,000 residents. Colorado currently has around $1.8 billion in yearly retail cannabis sales. This may suggest a similar possible level of sales for Minnesota once its retail cannabis market matures.

In a recent op-ed piece for Marijuana Moment, the New York cannabis consulting firm of Bridge West Consulting suggested three reasons, in addition to low cannabis excise taxes and reasonable license fees, why entrepreneurs should consider investing in a retail cannabis business in Minnesota:

Minnesota legislation prohibits localities from banning cannabis businesses. This avoids serious problems that have plagued cannabis businesses in other states including California and Montana in which access for cannabis companies has been denied and, in Montana’s case, even reversed. (Minnesota’s new legislation does allow local governments to limit the number of cannabis retailers to one for every 12,500 residents, however.)
Minnesota has allocated funds to assist social equity cannabis businesses, including $6 million to the CanStartup which will fund non-profits to make loans to budding cannabis businesses.
Bridge West makes the interesting observation that Minnesota is bordered by four states—Wisconsin, Iowa, South Dakota and North Dakota—none of which have legalized adult use cannabis. Moreover, an estimated 1.9 million people live outside of Minnesota within a 50-mile radius. That means that not only will Minnesotans not have to compete with out-of-state cannabis dispensaries but will benefit from the purchases of out-of-state residents that live within a comfortable distance.

How a License Application is Scored

HF100 gives some guidance as to how the Office of Cannabis Management (OCM) will score license applications, awarding points for the following 9 categories: social equity status, veteran status, security and record keeping, employee training plan, business plan and financial situation, diversity plan, labor and employment practices, knowledge and experience and environmental plan.

The OCM may award additional points if the applicant would expand service to an underrepresented market. Points may also be awarded to those applicants who can demonstrate a negative impact from cannabis prohibition such as arrest or imprisonment of the applicant or their immediate family. This is different from social equity status and the law says points may be awarded to the applicants “in the same manner as points are awarded to social equity applicants.”

Emphasis on Market Stability; Prohibition of Vertical Integration

Minnesota is taking measures to ensure “market stability,” which it doesn’t specifically define, but which it says involves:

Ensuring an adequate supply of cannabis, but not a glut.
Eliminating the illicit cannabis market.
Promoting a craft cannabis industry.
Prioritizing growth and recovery in communities that have experienced a disproportionate, negative impact from cannabis prohibition.

HF100 states, “The office shall issue the necessary number of licenses in order to ensure the sufficient supply of cannabis flower and cannabinoid products to meet demand, provide market stability, and limit the sale of unregulated cannabis flower and cannabinoid products.”

Continuing its emphasis on “smaller is better,” HF100 says, “Unless the office determines that the issuance of bulk cultivator licenses is necessary to ensure a sufficient supply of cannabis flower and cannabinoid products, the office shall not issue a bulk cultivator license before July 1, 2028.”

Vertical integration is also prohibited. “The office shall not issue licenses to a single applicant that would result in the applicant being vertically integrated.” HF100 goes on to state that microbusinesses are exempted, and that if the OCM determines that vertical integration is necessary to ensure a sufficient supply of cannabis and cannabis products during the first year of such products being sold to customers, it may authorize one or more applicants to be vertically integrated. However, such a group of licenses are very temporary and will expire at the end of that first year period.

An entity holding a cannabis retailer license may also hold a delivery license, a medical retailer license and an event organizer license. But no retailer may hold any other license. Also, no entity may own or operate more than one retail business in one city or county.

Interestingly, Minnesota is also allowing cities or counties to own and operate a municipal cannabis store, possibly similar to the way Utah has government liquor stores which compete with private bars, breweries, wineries and distilleries.

In Summary

Minnesota is just beginning to define and establish its adult use cannabis market. Like other states before it, it is attempting to promote social equity aims at the same time as it’s working to avoid the serious problems of a competitive illegal market and an over-or-under supply of cannabis to its citizens.

With low license fees and excise taxes and a good-sized population, 420CPA believes cannabis entrepreneurs should seriously consider Minnesota for possible investment. The first cannabis retail businesses are not expected to open for another 18 months, so now is the time for businesspeople to lay the groundwork for their applications and future locations.

Building An Integrated Pest Management Plan – Part 4

By Phil Gibson

No Comments

This is the fourth in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, an overview of the plan and pest identification, click here. For Part Two, on pest monitoring and record keeping, click here. For Part Three, on preventative measures, click here. Part Five comes out next week on how to build a framework for control actions and how to monitor them. More to come!

This is Part 4: Direct Control Options

Even when the best methods are implemented and precautions are taken to protect your infrastructure, determined pests can penetrate your perimeter. Before you see crawling, hopping or flying insects, or sickly-looking plants, be sure to implement your physical protection (positive pressure airflow sealed facilities) and personal hygiene methods (shoe baths, sticky mats, & air shower entrances) to protect your crops. Equip your employees with personal protection equipment (PPE) proper gloves, masks and clothing as discussed in our last chapter, preventative measures.

When things do break-out beyond your acceptable thresholds, Direct Control Options include non-chemical microbial biofungicides, microbial bioinsecticides and direct chemical control options. Lots of big scary words there, all of which are toxic even under safe application methods and when used at recommended concentrations levels. This means training in their use and protective clothing is required. Careful application of these control options is necessary so you exterminate your pests and not your people! This seems obvious, but do not just “wing it.”

These chemical elements can be applied in diluted concentration levels, manual wipe-down application, concentrated flush frequencies, or root drench applications, foliar spray mist applications, HVAC aerial diffusions and aerial knock-down sprays. You may even choose to remove badly infected plants and destroy them completely.

Use experts when you are planning for these tools. All of these methods require handling and safety precautions. Proper breathing filters, eye & skin protection, as well as disposable gowns/hazmat suits should be used when applications are performed and until the applications have dissipated to safe levels. Be careful not to co-mingle removed plant materials. Gloves become transport and infection spreaders after use.

Please also be sure to review your harvest testing requirements and what treatments are safe for your consumers and within legal limits. No one wants to have their harvest rejected due to pesticide contamination.

Figure 2: Municipal Water Treatment, RAIR Cannabis, Michigan

Clean-up after application may be required depending on the bioinsecticide or chemical that is used. Again, always ensure the safety of your employees and take precautions.

Start the application of your control options with your site map, room assignments and scout monitoring teams. Where does air flow into and within the facility? When your scouting team count logs go beyond your acceptable thresholds, here are some options for you.

Let’s begin with cleaning your irrigation and nutrient water sources. For a walk-through tutorial for incoming water treatment, humidity recovery and nutrient water recycling, please review the video tour of Water Treatment at RAIR Cannabis to see how an expert has done it.

From the IPM Planning Guide standpoint, peroxide and acid sterilizers can be used to clear irrigation water, for surface wipe-downs or as direct plant applications. We will cover those first. Caustic sterilizers require PPE for cleaning. Forgive my image here, we were just using water.

Concentrated Cleaners for Surfaces & Irrigation Sources (Hydrogen Peroxide & Sanitizers)

Plant interacting interfaces, i.e. surfaces, benches, walls, floors, trays, utensils, clippers, etc. should be sterilized with every use. Methods can include direct wipe-down or scrub, concentrated or diluted sprays or room vaporizers. A good example of hydrogen peroxide (H2O2) liquid would be a food grade sanitizer with 3-35% H2O2 content. Use acceptable diluted versions of these cleaners as appropriate.

Figure 3: Cleaning & Scrubbing, Where’s the PPE?

A commercial example would be Zerotol 2.0 with 27% H2O2 & their proprietary acid mix. Alternatively, you can use direct hydrogen peroxide generators from commercial sources to generate your H2O2 at various concentrations. More detailed examples are included in the complete Integrated Pest Management Guide (link at the end of this article). Establish your procedures for sterilizing your rooms and tools before you introduce plants, and describe what is to be done after every harvest and room turn. Track the cleaning materials used for your operational records. You will find this useful to track operational cost over time.

Sanitizing Acids for Surfaces & Irrigation Sources

Similar to hydrogen peroxide, hypochlorous acid (HOCl) comes in many commercial forms and can also be generated onsite using purchased generators. Commercial mix examples are UC Roots, Watermax and Athena Cleanse. They come in 0.028% to 15% concentrations. Self-generators range in output from highly precise 0.01% to 1% concentrations with more examples in the guide.

Treatment Tools

OK, so enough on cleaning preparation. Here are some tools that can be used to fight back against a pest intrusion:

Non-Chemical Microbial Biofungicide for Pathogens in Soil or Fertigation Water

Microbial fungicides are available to clear nutrient irrigation systems by minimizing pathogens and improving plant resistance to infections. Some fungicide versions target root pathogens by attacking the diseases directly. Others control or suppress common water carried challenges like pythium, rhizoctonia, phytophthora, fusarium and others. Brand names include Botanicare, Bonide, BioWorks, Actinovate, Mycostop and many more. Details covered in the guide.

Non-Chemical Microbial Bioinsecticides for Larval Stages

These biological tools attack the organisms or insects at a physical or mechanical way by breaking down the pest’s nervous system, biochemistry, or structural integrity (exoskeletons, etc.). These are engineered or living organisms (bugs to attack bugs) that are developed as targeted attacks for specific pests. Brand names are BioCeres, Botanigard, Venerate, Bio Solutions and others.

Minimal Risk Chemical Pesticides for Airborne Critters

Figure 3: Example Fungus Gnat Infestation – Royal Queen Seeds blog

Regularly approved for used in most locales, essential oils, natural acids (like citric acid) and insecticidal soap are commonly available in every hydroponic store. These work very well as safe spray “knock-down” insecticides for crawling or flying pests. Commercial examples use a proprietary mix of various oils, citric acids or isopropyl alcohol to do their task (examples in guide). Insecticidal soaps and fungicides for surface cleaning perform a similar purpose and typically use potassium salts or fatty acid mixtures.

Biochemical Pesticides

These tools are used to inhibit insect or fungal growth to acceptable levels. The multifaceted and commonly used neem oil comes in many commercial versions and is a naturally occurring pesticide extracted from the leaves and seeds of the neem tree. Example brand names are Bonide, Monterey, Triact and others. They range in concentrations from 0.9% to 70% concentrations. These oils suffocate living organisms or eliminate moisture to kill insects, spores or fungus at their initiation and throughout their lifespan.

Another option here are Azadirachtins. These act as insect growth regulators and disrupt the bugs natural evolution. Brand names are AzaGuard, AzaMax and others in the guide.

In summary, this week

We summarized some of the many pest control options available for water treatment, soil borne, intermediate or flying pests. We also covered various concentrations for these pesticide and sterilizer options. If you are not familiar with dilution ratios, %, PPM terms and how to apply the correct level of pesticide, you may find our plant science test kitchen blog on this topic of use here.

Chemical access and use should be restricted to employees familiar with their authorized application. PPE is very important to protect any employee that will come in contact with materials, liquids or vapors for chemical resources (gloves, boots, respirators, Tyvek (or equivalent protective wear) suits and eye protection or goggles.

For more detail on each of these treatments, you can see examples for your integrated pest management procedures in our complete white paper for Integrated Pest Management Recommendations, download the document here.

In our next chapter, Pest Population Control Actions, we will review control thresholds and example plans for a range of problems from biofilm build up to white flies and more. Our final chapter after that will suggest an emergency response framework and how to address pest outbreaks. See you next week.

The Sensory Branding Opportunity for Cannabis Products

By Dr. Ed Szczygiel

No Comments

Cannabis brands are facing a proverbial fork in the road: determining whether their product evolves into a luxury consumable or affordable agricultural commodity. While it is reasonable to assume the cannabis market space will organically grow into a luxury goods industry such as wine and spirits, the luxury brands that serve as the foundation of these markets were built over years of engagement between consumers, connoisseurs and producers. If cannabis companies want to successfully market their products as luxury items, a concerted effort towards well-defined, consumer-accessible branding is required.

The first step towards evolving a cannabis brand towards luxury is overcoming the fixation on cultivar identity. Unregulated cultivar naming currently impedes creativity and craftsmanship, disrupting brands and salespersons’ abilities to clearly communicate strain aesthetics.

The good news is the alcohol, coffee and consumer packaged food (CPG) industries have done most of the heavy lifting, paving the way with robust sensory science and analytical approaches to product characterization. Cannabis stakeholders need only adapt their tools and apply them to cannabis with similar intention.

Research suggests that aroma is one of the strongest predictors of positive consumption experience. As adult use consumers become familiar with current product offerings and increasingly legal availability, they will seek products that consistently yield the best experience. The most successful brands will be those that most effectively communicate that experience and then deliver it. The status quo – describing aroma using strain names, top terpenes or THC content – is not effective at harmonizing a brand’s promise with consumer experience.

Figure 1: Illustration of both the conventional branding approach (top) and the sensory-based branding opportunity (bottom).

The conventional cannabis product branding approach leaves to be desired a tremendous opportunity to characterize cultivars (Figure 1). Sensory science, the discipline used to evoke, measure, analyze and interpret reactions to materials through human perception, has been used for decades to characterize CPGs from skin lotion to washing machines. Adapting these well-established techniques for use in cannabis can be challenging, but it is certainly worth the investment.

These shifts in the cannabis industry have already begun to occur. I recently was the principle investigator on a white paper that presented a novel cannabis aroma wheel derived from aroma descriptors and a panel of trained sensory experts. In the study, sensory scientists evaluated randomly sampled cannabis flower over a period of several months. The researchers combined qualitative focus panels, literature review and formal blinded sensory tests to develop a comprehensive lexicon that served as a tool for trained evaluators to characterize cannabis aroma. This novel and robust tool (Figure 2) was designed to be used by trained panels to characterize cannabis aroma, is freely available and is just the beginning of a collective development of a data-driven cannabis lexicon.

Much like the World Coffee Research Lexicon referenced here, the Cannabis Aroma Lexicon is a tool with a specific purpose: collecting an objective description of the product aroma. It is a living document that will grow along with the industry. In the future, we may have lexicons to describe more than just aroma. Tactile and appearance sensory attributes of cannabis will gradually be defined by sensory scientists, presenting more opportunities for deep craftsmanship in the cannabis industry.

The role that dispensaries play in adoption of standardized quality metrics is critical. The product features that position cannabis to be a craft product warrant the presence of a third-party expert to translate and guide consumers during the purchasing process. It’s intuitive to ask a waiter to recommend a pairing (i.e., a dry red wine to pair with a seafood dish), given the trust that consumers put in the restaurant to understand the properties of the food they are serving. Dispensaries have thus far filled the service structure role for cannabis, but the vast amount of unknowns regarding the physiological and sensorial effects of cannabis have resulted in inconsistent experiences that leave something to be desired in terms of consumer trust.

Application of sensory science in cannabis is an unparalleled opportunity for brands to build consumer trust and differentiate their products in a sea of strain names and high potency flower. Cultivars that can be established as measurably aromatic in a specific character can leverage that aroma profile to add significant value to the product. For example:

Cultivar name can be aligned with the perceived aroma (e.g., garlic is not bad, but expecting tropical and getting garlic can harm consumer trust).
Product catalog can be consolidated and optimized to avoid sales cannibalization by growing specific products to meet consumer group’s needs.
Guesswork is removed from breeding by measuring when a product is meeting sensory goals and ensuring it doesn’t drift over time.
Demonstrating transparency will win over ethical consumers. Utilizing controlled, blinded studies to profile aromas will add value to ethics-minded consumers.
Becoming a leader in connoisseurship. In the forefront of this shift in branding, one can position a brand to be ahead of the competition.
Elevating the dispensary experience. By utilizing aroma profiling, products can be more easily sold by budtenders and salespeople.
Opening doors to new application types (e.g., seasonal, occasion centered or geographically unique cultivars).

These are just some of the ways that aroma characterization will differentiate products and simultaneously contribute to cannabis brands’ ability to communicate craftsmanship and the maturity of the industry as whole. Not only will adoption of robust sensory-based branding improve the consumer experience by providing a means to compare products to one another, it will promote adoption of good manufacturing practices that simultaneously improve the quality and safety of cannabis products. Without consumer-accessible quality metrics, brands have little incentive to produce products of elevated quality and are conversely incentivized to prioritize quantity and meet minimum regulatory requirements.

Importantly, cannabis businesses will use this tool to adapt to an inevitable industry-wide shift towards connoisseurship and application of robust sensory science. While it may be challenging to shake off the “bad habits” that currently plague many brands, cannabis has significant potential as a luxury good. Consumers are eager for a better cannabis experience from purchase to consumption. How will your brand use sensory profiling to expand or evolve product offerings to succeed in a cannabis market full of luxury brands and what steps will you take now to prepare?

Minnesota Legalizes Adult Use Cannabis: Part 1

By Abraham Finberg, Rachel Wright, Simon Menkes

No Comments

Part 1: The Current Status of Legalization

Minnesota has long been known as the “Land of 10,000 Lakes” and boasts over 14,000 bodies of fresh water covering at least 10 acres. The Dakota Sioux word for water, “Minne”, appears in the word Minnesota (clear blue water) and many locations around the state, including Lake Minnetonka (big water), Minnehaha Falls (waterfall) and Minneapolis (water + the Greek word for city).

With all this emphasis on water, it’s no wonder Minnesota’s cannabis-lovers are wondering whether the state’s new adult use legislation will issue in a river of profits for both the state and its future adult-use cannabis businesses.

Overview

In May 2023, House Bill HF100 was passed by the legislature and signed into law by Governor Tim Walz on May 30, 2023, making Minnesota the 23^rd state in the union to legalize adult use cannabis. Effective August 1, 2023, it will be legal to possess up to 2 pounds of flower (2 ounces in public), 8 grams of concentrate and 800 milligrams of infused edibles.

HF100 also established the Office of Cannabis Management (OCM), which will be responsible for overseeing the state’s adult-use program. Minnesota’s medical cannabis program, now under the auspices of the state’s Department of Health, will transition over to the OCM on March 1, 2025.

The OCM website makes clear that “the regulatory framework will take time to develop and will require input from communities throughout the state” and that “the legislation proposes that retail sales for adult use cannabis in Minnesota begin in the first quarter of 2025.”

Minnesota Licensing Framework

The legislation establishes sixteen licenses including ten adult use license types: microbusiness, mezzobusiness, cultivator, manufacturer, retailer, wholesaler, transporter, testing facility, event organizer and delivery service. There are also two hemp licenses and four medical cannabis licenses.

Adult use license fees are reasonable compared with other states with application fees from $500 to $10,000, initial license fees from $0 to $20,000 and annual renewal fees from $2,000 to $30,000.

The state also will give preference to social equity applicants and notes that “The legislation prioritizes applications for business licenses from people who live in low-income areas that have experienced a disproportionate impact from cannabis prohibition and for military veterans who lost honorable status due to a cannabis-related offense. Social equity includes people who were convicted of cannabis-related offenses before the effective date of the legislation.”

Taxation of Cannabis Sales

Tax on cannabis products will be limited to 10% in addition to the state sales tax of 6.875% and any local sales taxes which may already be in place. Local governments will not be allowed to collect an additional cannabis-specific tax. Additionally, medical cannabis sales will not be taxed at all. The combined adult-use cannabis excise tax of 16.875% gives Minnesota the fifth-lowest cannabis tax rate in the country, with only four other states—Michigan, Delaware, New Jersey and Maryland—offering marginally lower rates.

Cannabis tax revenue will be split 80% for the state’s general fund and 20% to local governments. These tax receipts will fund a wide range of programs including the Minnesota Department of Health’s prevention and education efforts (including for media campaigns), data collection and grants for local and Tribal public health departments to support education, technical assistance and outreach.

The Social Equity Factor

As with many other adult-use states, there is a strong social equity element in Minnesota’s legislation. The legislation calls for automatic expungement of low-level cannabis convictions and for creating a Cannabis Expungement Board, which will review felonies for expungement or resentencing.

The law also creates a Division of Social Equity within the OCM, which is charged with providing outreach and services to communities disproportionately affected by cannabis prohibition. HF100 states that “Status as a social equity applicant must account for at least 20 percent of the total available points.” This suggests a strong favoring of a social equity application but stops short of requiring a certain amount of social equity licenses be awarded at the beginning of the program, as has been the case in New York.

At this time, HF100 states that an individual qualifies as a social equity applicant if they’re:

a military veteran who lost honorable status due to a cannabis-related offense;
a resident for the last five years of [a] … neighborhood that experienced a disproportionately large amount of cannabis enforcement [as determined by the OCM]
a resident for the last five years of [a neighborhood] … where … the poverty rate was 20 percent or more; or … the median family income did not exceed 80 percent of statewide median family income.

To Recap

Minnesota just legalized adult-use cannabis with the passage of House Bill HF100 and is in the early stages of rolling out its program. The first adult-use sales aren’t expected to take place until the first quarter of 2025.

Just a cursory glance at the state’s adult-use cannabis program shows Minnesota is trying for a friendly, business-positive environment for new cannabis companies, especially considering its low excise tax and moderate licensing fees. As with most other adult-use states, the social equity factor will play an important part in the issuing of licenses and must be taken into consideration.

We at 420CPA encourage cannabis entrepreneurs to examine Minnesota as a potential location for their future cannabis business. To that end, our Part 2 will dive more deeply into Minnesota adult-use with these topics:

Building An Integrated Pest Management Plan – Part 3

By Phil Gibson

No Comments

This is the third in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, click here. For Part Two, click here. Part Four comes out next week and covers direct control options for pest reduction. More to come!

This is Part 3: Preventive Measures

Preventive measures are a great investment in the profitability of your operations. Our objective is to ensure successful repeat harvests forever. Build your procedures with this in mind. This means maintenance and regular review. We all realize that this work can be monotonous drudgery (we know!), but these procedures will ensure your success.

Figure 1: New Air Shower Access Installation

As a summary to begin, pest access must be limited wherever possible. Employees are the first place to start, but we must also return to our site map and review our facility design and workflows. Every operation has to move plants from nursery through harvest and post-harvest. Where should cleaning happen? Of course, you have to clean up post-harvest but when should this occur during the grow cycle? What is the best way to monitor and clean environmental management systems (i.e. air, water) and what are the weaknesses in the physical barriers between operations? Let’s walk through these issues one-by-one.

Employee Access and Sterile Equipment

Follow procedures to screen and protect your employees both to eliminate pests and to avoid exposing your employees to harmful chemicals or storage areas. Look for ways to isolate your workflow from pest access. Be certain that your facility is airtight and sealed with filtration of molds, spores and live organisms in your air intake areas. Air showers at your access points are important to screen your employees on their way into your gowning areas and grow facility. Clothing should be standardized and shoe coverings or crocs should be provided for all employees that access your interior. Look for ways to stop all pests (embedded, crawling, hopping or flying) in all of your room assignments (mothers, clone, veg, flower, trim and drying). This can be improved with shoe baths, sticky mats, frequent hygiene (hand washing and cleaning stations) and procedures for entry.

Always consider requiring hair & beard nets, shoe covers and disposable gloves in plant sensitive areas.

Chemical Access & Protective Equipment

Figure 2: Example Facility Map – Understand Workflow & Barriers to Pest Access

Personal protection equipment (PPE) is very important to protect any employee that will come in contact with materials, liquids or vapors for chemical resources. Establish procedures for chemical use and train employees in the safe handling of these materials. Typical equipment includes high density chemical protective gloves, boots, respirators, Tyvek (or equivalent protective wear) suits and eye protection or goggles.

Chemical access areas and their use should be restricted to employees familiar with their authorized application. Always remember that cannabis is an accumulator plant, and it will absorb and hold onto chemical treatments. Appropriate isolation and safety procedures must be followed for chemical use. Not following these restrictions can expose your employees to dangerous chemicals or get your entire harvests rejected at testing.

Facility Map & Workflow

Because insects would like to be everywhere and they come in many types (root zone, crawling, flying, microscopic, bacterial or biofilm), the facility workflow must understand where they are and how they might migrate if they penetrate your defenses. Note airflows in your rooms and fan locations so migrations can be predicted once an infestation is located. Where are your opportunities for full clean-up and disaster recovery in your building? Where should you stage maintenance filters, test kits, water and cleaning materials. How best to clean up and dispose of sealed garbage containers or cleaning materials?

Operational Cleaning & Post-Harvest Reset

When compiling your preventative measure documents, it is critical to create a repeatable operating procedure for cleaning and sanitizing your rooms, systems, and growing spaces after each harvest. Plant material handling, cleaning surfaces and wipe methods should all be documented in your Standard Operating Procedures (SOPs). Define what “clean” is. Removing plants and plant debris is pretty clear but define how to drain reservoirs, clean pipes, change filters and clean and sterilize your rooms. Operators must be trained in these SOPs and reminded of their content on a regular schedule. This is how you avoid outbreaks that can crush your profits.

Physical Barriers & Maintenance

Document your sealed spaces and define your normal room and access door barrier interfaces. Review the status of any known cracks or gaps in your perimeter. Are there any known leaks or piping that has been seen as a risk or a problem in the past? Are there any discoloring or resident mold locations (Never happens, right?). Baseline how much time and people resource a harvest operation and cleaning effort should take. Will you do this after every harvest or compromise your risk by delaying to every third or fourth harvest? Create your barrier SOP.

Environmental Control & HVAC

Managing the air quality provided to your plants is critical to your yields. Controlling CO2, air movement rates (the leaf happy dance), humidity, air filtration and sterilization methods must be maintained and cleaned on a regular basis. Do you need to change the HEPA or other particulate filters? Is there any UV light sterilization maintenance? We have all seen the home HVAC air conduit cleaning commercials. Your commercial facility is no different. How will you clean your air and water plumbing systems? How often will you perform this full reset? When will you calibrate and data log your sensors for temperature, humidity, CO2 and water resources? Put everything about your environmental set points into your maintenance document and decide when to validate these. Molds, mildews and biofilm hazards are all waiting for unmonitored systems to open the door for access.

In Conclusion, This Week

If you’re an IPM nerd and this dynamic topic did not put you to sleep, you can read more detail and examples for your integrated pest management procedures in ourcomplete white paper for Integrated Pest Management Recommendations, download the document here.

In our next chapter, Direct Control Options, we will review what you can use to protect or recover control of your facility including both chemical and non-chemical tools and methods. In our final two chapters, we will discuss extermination of the determined pests that breach your defenses. And with great expectations, our final chapter will discuss emergency response and time to go to war!

Part Four comes out next week. See you again soon!

The Craft Cannabis Cavalry: A Story of Small Business & Economic Empowerment

By Aaron G. Biros

No Comments

The Tohiyusdv Cavalry is a black-owned small business based in rural Virginia. At its core, they grow and process cannabis for CBD products, but it’s really much more than that. Through its Precision Craft Farmer Program, the company works with existing small minority-owned farms to introduce them to the cannabis market.

Via land leasing, profit-sharing, crop-sharing, facility design, community involvement and incubator-style support, Tohiyusdv Cavalry has built a network of farmers and a community around them that work together to gain access to the larger cannabis market.

Tohiyusdv, pronounced “toe-hee-yoos-da,” means “calm” and comes from a Native American dialect in the region. James Arrington III, founder of the company, is both African American and Native American, so the name is a nod to his roots. While Arrington insists he is just one part of this larger organization, it’s his passion for community, small business, social equity and cannabis that drives the company.

We sat down with James to learn more about the Tohiyusdv Cavalry, a bit of his background, how him and his community have found success and what they hope to achieve.

Different Sides of the Tracks

He grew up in Norfolk, Virginia alongside his two brothers and sister with a view of two different lifestyles. “We grew up in the hood of Huntersville, but I was raised in a white church, so it was interesting seeing both sides of the tracks and seeing the side that some of my friends couldn’t see,” says Arrington. The dichotomy of his upbringing gave him a unique perspective that he took to heart, eventually going to Old Dominion University for electrical engineering at the encouragement of a teacher.

Throughout his formative years, he didn’t really get involved with cannabis – that came much later. In his college years though, he met his Delta Chi fraternity brother Ernest Toney, who would go on to become the founder of BIPOCann, a nonprofit that helps social equity entrepreneurs, minority business owners and professionals in the cannabis industry.

Arrington with a recent indoor hemp crop

Working as an electrician to pay for tuition, Arrington graduated and launched what would become a successful career in electrical engineering. He worked as a subcontractor for the government in warzones, designing electrical systems with security and defense in mind, before starting his own company CalArr Consulting. “What really tied me to the industry was when I started using cannabis for my mental health and to understand who I am,” says Arrington. A combination of his upbringing and his career led to his PTSD, which then led him to cannabis as a tool for his wellbeing and mental health.

More recently, he spoke with Ernest Toney, who said, “Look man, I’ve seen what you’ve done with your business over the years and you should consider getting into the cannabis industry.” Arrington took that advice and ran with it. “So, the company I started is a mission-driven company based around healing, cannabis, understanding and helping people,” says Arrington. “Tohiyusdv Cavalry is based around working with small farmers and minorities; We introduce them to the cannabis industry.”

Here Comes the Cavalry

Right now, his company works with hemp and CBD products, but he says they are looking to expand into the THC market once Virginia legalizes and they already have some partners they’re working with in other states to expand the program.

Tohiyusdv Cavalry has been around for about two years now and Arrington says the heartbeat of it is their craft farmer program. “These are existing minority farmers in a community, already growing crops like soybean or corn,” says Arrington. “These are generational farms that have been passed down through family, some of them almost 100 years. They’ve always had to change with the times.” In changing with the times, a lot of these small, rural farms are seeing the hemp market as a possible pivot, but hardly know where to begin. “They are starting to hear about farmers in their community growing hemp, but having trouble finding folks to buy their crop.”

Some of the products from Tohiysudv Cavalry

That’s where the Cavalry comes in. “What you see in minority backgrounds is a lot of opportunities like this that are very scary to step into,” says Arrington. “We’re teaching people how to get into the industry, helping them through processing and getting on the market using new technology, and we do it at their pace.” Some folks in their network just want to rent space on their farm out to a hemp grower, others want to dive right in and create CBD products. They operate a white label program for some and help set up turnkey facilities complete with extraction and processing for others. “We work with them to build a community around their farm,” says Arrington. “We are just the engine behind these small farmers helping them get access to the larger market.”

From the Ground Up

A good example of the work they put in is Everbreeze Acres. Based in Rustburg, Virginia, Everbreeze is a 434-acre farm and bakery that’s been in the same family for generations. They had an interest in the cannabis market, so they approached Tohiyusdv Cavalry. James and his crew came in and built a 2,000-square-foot facility that is hydroponic, fully turnkey and automated. “We are teaching them the process and turning it over to them,” says Arrington. “We are teaching them how to take care of the plants, grow the crop, harvest and process it, all while collecting data.”

Before brainstorming how they want to market their products and how they want to be represented, the owners of the farm were still a little skeptical. Being in their 70s, they wanted to make a product that has some medicinal properties and could help people take care of themselves. So, James and his team put together a plan to launch a daily supplement, akin to a multivitamin.

Now Everbreeze Acres is using CBD as a megaphone to communicate their story. They were wary at first, but learned about it, grew to like it and now run a fruitful cannabis business. “We have their facility up and running and we’re growing several strains that work best for them right now,” says Arrington. “We’re about a month away from another harvest there.”

Building Community

Everbreeze Acres embodies the concept of the Tohiyusdv Cavalry. Helping small farmers establish themselves in the cannabis industry, building community around them and working to help their following and their mission.

Small business is the keystone of many communities, the cannabis industry included. Economic empowerment is sort of a way of staving off big business too. Given the history of big tobacco in the Virginia area, many stakeholders are worried if they’ll still have a seat at the table when Virginia legalizes adult use cannabis. “Looking at it in that sense, we are hoping that creating this group of diverse minds and backgrounds is building a table where everyone can sit at,” says Arrington. “We want to provide that place for them and let them know that, yes, this is the room for you, this is the place for you. We’re lending a helping hand and giving them a voice and a megaphone, sharing what they want to see in this industry.”

When asked what advice James would give himself ten years ago, the mood was somber. “Ten years ago, my mentor, alumni Dave “BamBam” Hoffman died. I would say that was the thing that gave me that kick in the ass, that I wasn’t doing everything I could do.” He has the same advice for minorities and indigenous people getting into the industry now: “Don’t be afraid to do it, the skills that you have you can put into the industry in some way. Your fit is out there. If it’s the right way, it’s never going to be easy. Push through it, keep going,” he says.

Growing in Virginia

Tohiyusdv Cavalry is ready for the day that Virginia legalizes adult use cannabis, but James says he hopes they make room for the small farmers. “Small farmers are what makes Virginia, Virginia.” They are in talks with some larger medical cannabis companies about creating similar programs for sourcing from craft growers. Through their strategic partners, a big part of their work right now is around partner and sponsor outreach, getting more businesses interested in sponsoring facilities and investing with small farmers. “Our hope is that we’ll be able to keep expanding the program and involve more minority farmers in Virginia and that it will only keep growing,” he says. “We’re optimistic that we’ll have three more farms signing on this year. And hopefully when Virginia legalizes adult use cannabis soon, we’ll be ready to expand in that market and keep on growing.”

Desperate California Cannabis Vendors Seek Credit Protection

By Abraham Finberg, Rachel Wright, Simon Menkes

No Comments

Cannabis companies representing 45% of California’s cannabis sales are pushing a bill that will crack down on non-paying customers. Well known operators, including Kiva, Lowell Farms, Nabis and Sunderstorm, recently formed Financial Stability for California Cannabis (FSCC) and moved to support Assembly Bill 766.”

The bill, nicknamed “The Cannabis Credit Protection Act,” would require a cannabis licensee to pay for goods and services sold or transferred by another licensee no later than 15 days following the final date set forth in the invoice. If full payment is not received by that date, the seller would be required to report this to the Department of Cannabis Control (DCC), which in turn would notify the delinquent buyer and begin disciplinary proceedings. The buyer would be prohibited from purchasing any other cannabis products on credit until the delinquent invoice was paid. In addition, the DCC would be empowered to issue a penalty (unspecified), taking into account “the frequency and gravity of the licensee’s [past] failure to pay outstanding invoices”.

In a letter of support for AB 766, the FSCC stated, “This culture of nonpayment that has emerged in California’s cannabis market leaves businesses across the entire industry and supply chain – as well as ancillary businesses that support legal cannabis operators – with outstanding balances and unpaid invoices sometimes totaling hundreds of thousands of dollars…This ballooning debt bubble in the cannabis industry will only continue to grow without proper oversight, putting the entirety of the state’s supply chain at risk of collapse and impacting state revenue decline even further.”

Opponents of the bill acknowledge the problem of non-payment in the industry, but feel AB 766 is too heavy handed and is “ripe for abuse.” In a blog post for the international legal firm Harris Bricken, cannabis attorney Griffen Thorne writes, “[L]icensees who are reported would be legally prohibited from buying goods or services on credit from other licensees until they pay the invoices for which they were reported in full … The person making the report has to give the DCC almost no information in order to make the report. There is no hearing. There does not even seem to be an opportunity to contest the report. The second a report is made, the other side loses its rights to buy goods on credit – presumably even under preexisting contractual arrangements with third parties. This seems like an obvious due process concern and ripe for abuse.”

The number and amounts of unpaid cannabis product invoices have ballooned over time and have driven California cannabis vendors to take such extreme measures. Collections and outstanding receivables are a symptom of an industry struggling under heavy taxes and competition from illegal operations that pay no taxes whatsoever, and which now account for over 60% of all cannabis sales within the state.

In order to ascertain the current status of AB 766, 420CPA reached out to Assemblymember Phil Ting (D-San Francisco), co-sponsor of the bill along with FSCC, the Cannabis Distribution Association, California Cannabis Industry Association and the California Cannabis Manufacturers Association. We corresponded with Tania Dikho, Ting’s Legislative Director. Ms. Dikho informed us that the bill was heard in the Assembly Appropriations Committee on May 18, but it was not passed.

“It’s a 2-year bill meaning we can’t act on it until this legislative year is over, so the bill will not have another hearing [and we] can’t make any changes to it until next year,” explained Ms. Dikho.

The 2-year status is a tenuous one. The bill must be approved by the Assembly and make its way to the Senate between early January 2024 and January 31, 2024 or it may no longer be acted upon and will die a legislative death.

Businesses that would like to voice their opinion for or against AB 766 should contact their state legislative representatives.

Building An Integrated Pest Management Plan – Part 2

By Phil Gibson

No Comments

This is the second part of a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, click here. Part Three comes out next week and covers prioritization and preventative measures. Stay tuned for more!

This is Part 2: Pest Monitoring, Record Keeping, & Communications

Begin your pest identification process with a pest scouting document. You have already mapped out your facility with locations and potential access locations. For each of these pest types and room type assignments (mothers, clone, veg, flower), identify your employee scouts, their scouting methods, scouting frequency and the type of likely pest they are to search for and count.

Insect Types and Tracking Methods

Figure 1: Example Sticky Trap Scouting Map

Insect pest types include, but are not limited to, airborne flying or crawling insects, their various egg, lymph, larvae, pupal shells or immature forms. Look for trace remnants, plant damage or feces that let you know they are present in some form. If they are at the mature jumping or flying stage, this can be harder to count, but sticky traps distributed on an even basis around your rooms can make the counting process more consistent from survey to survey.

Note airflows in your rooms and fan locations so migrations can be predicted once an infestation is located.

Insects Can Be Everywhere – Crawlers & Fliers

Insects would like to be everywhere so they come in many types from the obvious flying and crawling types to root-zone microscopic, aquatic, fungal, bacterial or biofilm based. For those of you using soil or media, root-zone insects can be beneficial by digesting and breaking down organic matter into something useful for your plant’s roots (earthworms) or harmful by feeding directly on your plant roots and sucking the life out of your plants from out-of-sight below (nematodes, maggots).

Common pests in a cannabis environment include:

White flies – Oval shaped eggs on the underside of leaves, nymphs- oval crawlers that suck on the undersides of leaves, larger stage nymphs with pupae shells as they form wings and mature white flies.
Fungus gnats – Clear eggs deposited in overly wet soil or dead plant matter. Clear or white colored larvae in the soil or media, these worm-like critters go through multiple stages of molting as they grow, eventually pupating into brown cocoons and finally small black or dark flies with clear wings that flutter around your plants and suck on your leaves.
The dreaded spider mite – Clear, hard to see eggs on the underside of your leaves. These six-legged tiny moving bubbles begin the feeding as larva, add 2 legs in the intermediate and mature nymph stages and finally the oval shaped spider mites that every grower despises, adding their webs around the tops of your plants as their nurseries suck the life out of your flowers.

Insect Transfers of Bacterial Infections

Many crawlers or fliers you may discover in your grow operation do not generate fungus or bacteria on their own. However, they do routinely pick these up along the feeding way and bring them into your shop. Sap-feeding insects like leafhoppers and aphids use their needle mouths to pierce your leaves to suck on the sap that is nourishing your greenery. These insects consume the fluids and transfer bacteria as they feed. Whiteflies fit into this category of leaf sucking bacteria carrying pests. These pests can make your healthy grow rooms look blotchy with color drained out of your canopy.

Obvious symptoms of these flying/hopping pests are sticky leaves, black fungus mold, or yellowing leaves that show up at the bottom of your plants and work their way upward as the infestation progresses. Leaf curling or plant wilting will be visible in the more advanced stages of these pests.

As if crawlers were not bad enough, invisible fungus and bacteria that get into your water supplies can be the worst challenges of any grow.

Water Sourced Bacteria

Baseline testing of your feed water is critical for any facility. This is true whether you are using surface water, well water or municipal water. Please see the water tutorials on the AEssenseGrows website for details on how to test your water sources and what to look for in the mineral content.

Regardless of your water source, bacteria can be present directly in your water supply, or it can be introduced from infected plant materials from one of your suppliers. Pythium, fusarium and the latest plague, hop latent viroid, are some of the most common threats that attack your plants from your water or soil sources. These can come from your wells, feed lines or plant materials.

Reverse osmosis (RO) is a typical method to clear water of most pathogens and bacteria using water that is pressed through filters with very small membrane apertures. These small openings usually stop impurities, salts and microorganisms. Of course, these systems come in many different types and they have to be maintained to keep their performance quality. Don’t take shortcuts on your RO system.

Once your water source is clean, strict hygiene procedures for tools, equipment and plumbing are the best way to minimize these threats to your plants downstream from your water source. These cleaning efforts are not a guarantee. Pests can still get into even the best facilities. Symptoms of these maladies vary, but root rot, stunted growth, wilting, discolored roots or leaves, and in some cases, the quick death of your plants is possible depending on the critter.

Use your scouting regimen and your data mapping to locate infestations before they expand and damage your facility. Isolate outbreaks and take appropriate measures to address the pests. We will give you suggestions on prioritization and preventative measures to take in the next chapter.

Pythium is one of the most commonly harbored soil or water carried pests. When it is present and gets into your plants through cuts, natural openings, root surfaces or leaves on weakened plants, it can be devastating. In hydroponic systems, dirty looking brown roots evolve into full root rot if not addressed. Pythium is often the cause. In soil operations, pythium often shows up as wilting or yellowing patches on leaves.

Your lab testing partners are your friends when it comes to bacterial or fungal infections. Many diseases can resemble one another. It is not hard to misdiagnose environmental stress such as overheating or overwatering for a bacterial problem. Test results are necessary to accurately diagnose a problem.

Truly Airborne Molds & Mildews

Pythium and fusarium are not just present in water. They can also be airborne. Grey mold (botrytis) and powdery mildew are also common airborne pests. Proper humidity, air movement, air filtration and sterilization using HEPA (High-Efficiency Particulate Air) filters, activated carbon filters (also filter smells) and UV light sterilization can minimize these problems in your grow. Powdery mildew is the primary evil spore in this category. Airflow and regular cleaning to discourage fungal growth is the best way to limit these pests.

In conclusion, this week

Now that we have talked about identification (and clearly, this is not an exhaustive list), we will move into how to build in the cultural methods to prevent these problems from taking hold and ruining your business. In later chapters, we will dive into prioritization, treatment and control options for infestations, finally moving into control actions and emergency response.

Your integrated management response is how you pull all of this together and use your IPM procedures to increase your profitability. For the complete white paper on Integrated Pest Management Recommendations, download the document here.

Part three comes out next week and will delve into the world of Preventative Measures. Stay tuned for more!
