Building An Integrated Pest Management Plan – Part 2

By Phil Gibson

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.

Risk Management Considerations for Cannabis Retailers in New Jersey

By Eric Schneider

No Comments

Despite the US making cannabis regulations challenging to navigate, the industry is snowballing toward profitability. New Jersey legalized adult use cannabis on April 21 this year. One month earlier, The Garden State began accepting applications for Class 5: Retailers, Dispensing and Delivery.

Although New Jersey isn’t shy about its licensing requirements and standards, many people want to know how retailers can stay in the game for the long run. So, let’s talk about risk management considerations New Jersey retailers need to know.

Top Risks Cannabis Retailers Face in New Jersey

Regardless of what kind of retailer you operate —medical or adult use — it’s critical to know what you’re up against. The following are the most common risks we’ve watched cannabis retailers face daily in New Jersey, making a customized risk management strategy necessary.

Theft

Like other retailers, New Jersey cannabis retailers are vulnerable to theft. Unfortunately, theft can come from various angles, such as in-store, in-transit and insider crime. Besides cannabis retailers typically having a well-stocked inventory, it’s not uncommon for them to have more cash on hand than most other businesses.

Although the SAFE Banking Act could positively impact the cannabis industry, it’s in a notorious stall yet again. Briefly, the SAFE Banking Act would no longer allow financial institutions, such as banks and credit card companies, to refuse to do business with cannabis companies. However, cannabis retailers must operate in a cash-only environment, for now, forcing them to make bank runs multiple times a day. We probably don’t have to explain how enticing a significant inventory and fat bank bags look to criminals.

Cybersecurity

Since the onset of the global health crisis, the cyber liability landscape has nearly spun into a death spiral. In other words, cybercriminals sat on the edge of their seats during the pandemic, waiting to pounce on anything that looked slightly vulnerable. Remote workers, small businesses, and emerging industries were hard-hit.

It’s no surprise that New Jersey cannabis retailers face many cybersecurity risks through their point of sale (POS) systems. Additionally, retailers often gather and store personal information, such as email addresses, credit card numbers, shipping addresses, etc. Hackers and cybercriminals gravitate to this vital data rapidly.

Property Damage

In addition to the risk of theft, as mentioned above, cannabis retailers must protect their property from losses. Without adequate protection, damage to equipment or buildings could add up to high out-of-pocket costs. Consider the damage a weekend office fire or late-night vandalism would cause. If property damage occurs, retailers must figure out how to sustain business operations while recovering from the loss simultaneously. As a result, New Jersey retailers must protect their property and maintain business continuity.

How to Customize a Risk Management Strategy

Watch or listen to any news reports and there’s a decent chance that you’ll feel some slight sense of doom and gloom. And sure, a lot is going wrong in our world; however, that doesn’t need to impact how you perceive your businesses. Instead of casting a massive net over every possible risk that you can imagine, we recommend trying the following 5-step approach. Here’s the gist:

Identify: Pinpoint high-level risks that are specific to the cannabis industry. Then, let the process trickle down to focus on company-specific exposures.
Analyze: Determine how badly a particular risk could harm your retail company. How much will this hurt should the “what-ifs” play out?
Evaluate: Categorize risks according to how risk tolerant your company is. Will you avoid, transfer, mitigate or accept the risk?
Track: Use your history or the stats from a similar retailer to map out how you’ve handled the risk over time. Older retailers have an advantage over younger retailers, of course, but you can still get a feel for your risk management style.
Treat: Make good on your evaluation promises by avoiding, transferring, mitigating, or accepting the various risks you identified.

Recommended Insurance for New Jersey Retailers

Sales totals in the first month of New Jersey’s adult use market

The New Jersey Cannabis Regulatory Commission issued detailed requirements for new cannabis businesses. That said, part of the application requirements considered is the plan for companies to obtain liability insurance. Many new retailers opted for a “letter of commitment” as opposed to a certificate of insurance (COI), stating their plans for obtaining the following coverages:

Commercial general liability: Protects cannabis companies against basic business risks.
Product liability: Protects against claims alleging your product or service caused injury or damage.
Property: Reimburses cannabis companies for direct property losses.
Workers’ compensation: Covers employees if they are injured on the job and can no longer work.

In addition to the required insurance coverages, we recommend New Jersey retailers customize their risk management package with these policies:

Crime: Protects your cannabis company against specific money theft crimes.
Cyber: Protects your cannabis company against damages from specific electronic activities.
Directors & officers: Protects corporate directors’ and officers’ personal assets if they are sued.
Employment practices liability: Protects cannabis companies against employment-related lawsuits.
Professional liability: Protects cannabis companies against lawsuits of inferior work or service.

With more states in the US entering the marketplace soon, New Jersey is doing its fair share of the heavy lifting by spearheading the onboarding process. Remember, doing your due diligence at the start pays off in the long run — New Jersey retailers are proving that. Consider teaming with a commercial insurance broker calibrated to the cannabis industry, so you get the most out of your broker, marketplace and the cannabis industry as a whole.

Top Five Insurances Cannabis Businesses Need in 2022

By Eric Rahn

No Comments

Cannabis remains one of the fastest growing industries with no signs of slowing down. According to a recent article in Forbes Magazine, the legal cannabis market is poised to grow 20-30% per year to the tune of $50 billion by 2026.[1]With great opportunity comes numerous risks. Claims and lawsuits against cannabis businesses are increasing in frequency and magnitude. As an insurance broker who specializes in the cannabis industry and works with a wide variety of cannabis, hemp and CBD businesses in every state where cannabis laws are established, our recent analysis has unveiled the top five insurances your cannabis business needs in 2022.

General Liability

General liability is the most essential coverage your business needs to protect you from a variety of claims including personal injury, bodily harm, property damage and other situations that may arise including slander, libel, copyright infringement and more.

Since general liability is not always required to obtain a cannabis license, many businesses are tempted to forgo the expense. This is one of the biggest mistakes you can make as one single lawsuit has the potential to cripple your business. With a comprehensive, cannabis-specific general liability insurance policy in place, your insurance company, not you, will pay medical expenses and property damage claims from third parties, in addition to hefty legal fees and fines.

Property & Casualty Insurance

P&C insurance is an important part of your security and protection plan.

If you own a dispensary, grow operation, warehouse, testing facility or any other type of cannabis business with inventory, you need to protect your assets from potential loss or damage. Property & casualty (P&C) insurance safeguards your business against common and costly perils such as a fire, lightning, explosion/implosion, and even less common – but still possible – risks like riots, strikes and terrorism.

P&C insurance not only pays for damages to your business property resulting from a covered loss but it also covers the contents within your place of business, including office furniture, computers, inventory and other assets essential to your business operations. There are policies that will also provide the funds required to keep your business afloat until the damages from the loss are repaired. Any cannabis business with a physical property and location(s) should have a comprehensive property and casualty P&C policy in place.

Product Liability/Product Recall

Recently, we’ve seen a dramatic influx of product liability claims, and in particular, product recalls. Lawsuits have ranged from a single plaintiff seeking damages for personal injuries to class action lawsuits where a defective product is tied to an entire group of claimants.

control the room environment — Preventing contamination can save a business from extremely costly recalls. Having the right insurance can prevent a recall from becoming costly in the first place.

As a cannabis business owner, you can be sued for any damage resulting from products that cause harm to others, this includes false advertising, mislabeled or defective products. No matter where you are in the supply chain, your business could be held liable. The process of defending litigation or reaching a settlement agreement can completely drain a company’s resources. You’ll have to deal with regulatory compliance, producing and distributing product warnings, recalling products, claim investigation, product testing and additional risk assessment.

Product liability insurance is often overlooked, especially by small to mid-size businesses. However, your cannabis business needs this type of coverage if you sell any goods or products that end up in the hands of the public. In fact, your business may be contractually obligated to have product liability insurance. One such lawsuit is enough to fold a business due to costly legal fees and fines, as well reputation damage beyond repair.

Product liability insurance is designed to protect your cannabis company from claims that can happen anywhere along the supply chain, including product contamination, mislabeled products, false advertising or defective products. With proper coverage, your insurance company will pay for damages and legal expenses if you are sued, up to your policy limits. Your product liability policy will also cover any medical expenses for those who are harmed by your business. Making sure your insurance policy includes product liability insurance should be a top priority in 2022.

Cyber Defense/Data Breach Insurance

Cyber fraud and data breaches are two of the greatest risks facing cannabis companies in 2022. With so much cash pouring into the space, cannabis businesses of all sizes are bulls-eye targets for cybercriminals. Even the smallest of cannabis businesses are at risk of data breaches because they are part of a larger interconnected network of seed to sale vendors. These types of crimes can have detrimental effects on your business in numerous ways. In the case of a data breach resulting in the disclosure of a third party’s private information, the third party could sue your business. The SEC could also find your company negligent in cyber fraud cases and impose significant fines.

By forgoing cyber defense & data breach insurance, your business will be solely responsible for expensive legal bills, significant revenue losses and hefty fines and penalties from regulators. Cyber defense & data breach insurance is a must-have coverage in 2022, and beyond, to protect your business from cybercrimes.

Directors & Officers Insurance

If you are looking to secure venture capital or funding from investors in 2022, and/or attract and retain qualified leadership, you need directors & officers (D&O) Insurance. D&O protects corporate directors and officers, as well as their spouses and estates, from being personally liable in the event your company is sued by investors, employees, vendors, competitors, customers, or other parties, for actual or alleged wrongful acts in managing the company. In the event of litigation, your D&O insurance will cover legal fees, fines, settlements and other expensive costs.

D&O is often the most overlooked coverage because many cannabis businesses are independently run, and no one foresees the potential for operational failures and mismanagement. However, businesses with any sort of vision for growth should make D&O a top priority. It not only protects your current executives and board members but is critical in attracting leading talent in the space, as well as drawing in new investors to scale up your business. In fact, we’re seeing more prospective investors and board members requiring D&O insurance prior to engaging with a company to ensure they are fully protected in the event of litigation.

When it comes to mitigating risk in this business, the stakes are sky high. Cannabis companies that have not incorporated risk management into their business/operational plans will need to in 2022. It all boils down to the THREE P’s: being “Proactive, Prepared and Protected.”

Moisture Matters: Why Humidity Can Make or Break a Cannabis Cultivator’s Bottom Line

By Sean Knutsen

1 Comment

Vintners have known for centuries that every step in the winemaking process—from cultivation and harvest techniques to fermentation, aging and bottling—has immense impact on the quality and value of the final product.

And that same level of scrutiny is now being applied to cannabis production.

As someone who has worked in the consumer-packaged goods (CPG) space for decades, I’ve been interested in finding out how post-harvest storage and packaging affect the quality and value of cannabis flower. After digging into the issue some more, storage conditions and humidity levels have indeed come into focus as major factors, beyond just the challenges of preventing mold.

Weighty Matters

I enlisted my research team at Boveda, which has studied moisture control in all manner of manufactured and natural CPG products, to look closer at what’s happening with cannabis once it leaves the cultivation room. There’s not a lot of research on cannabis storage—we checked—and so we explored this aspect further. We were frankly surprised by what a big effect evaporation has on quality and how this is playing out on the retail level.

We suspected moisture loss could affect the bottom line too, and so we did some number-crunching.

It’s well understood that the weight of cannabis flower directly correlates with its profitability—the heavier the yield, the higher the market value. Here’s what our analysis found: A mere 5% dip below the optimal relative humidity (RH) storage environment eliminates six pounds per every 1,000 pounds of cannabis flower. At $5 per gram wholesale, that works out to upwards of $13,500 in lost revenue—and that’s with just a 5% drop in RH below the target range of 55-65% established by ASTM International, an independent industry standards organization.

We also purchased flower at retailers in multiple state markets and commissioned a lab to test the samples, which revealed that most strains sold today are well below the optimal RH range (55-65%). Regardless of fluctuating wholesale prices, when you do the math it’s clear that tens of thousands of dollars in revenue are simply evaporating into thin air.

Why So Dry?

Historically, cultivators, processors and packagers have emphasized keeping flower below a particular humidity “ceiling” for a reason: Flower that’s too moist is prone to hazardous mold and microbial growth, so it’s understandable that many operators err on the side of being overly dry.

The misconception that cannabis flower can be “rehydrated” is another cause of dryness damage. But this method irrevocably damages the quality of the flower through trichome damage.

trichome close up — The fine outgrowths, referred to as trichomes, house the majority of the plant’s resin

Those delicate plant structures that house the all-important cannabinoids and terpenes become brittle and fragile when stored in an overly dry environment, and are prone to breaking off from the flower; they cannot not be recovered even if the flower is later rehydrated.

When trichomes are compromised, terpenes responsible for the aroma, taste and scent of cannabis also can evaporate. Overly dried-out cannabis doesn’t just lose weight and efficacy—it loses shelf appeal, which is particularly risky in today’s market.

Today’s consumers have an appreciation for how premium flower should look, smell and taste. Rehydration cannot put terpenes back in the flower, nor can it re-attach trichomes to the flower, which is why preservation of these elements is so key.

Cannabis Humidity Control

Cured cannabis flower can remain in storage potentially for months prior to sale or consumption. By the time it reaches the end consumer, much of the cannabis sold in regulated environments in the U.S. and Canada has suffered from dry damage.

There are various humidity controls available for cannabis cultivators: desiccants that absorb water vapor; mechanical equipment that alters RH on a larger scale; or two-way humidity-control packets designed for storage containers.

In the CPG sector, with other moisture-sensitive products such as foods and electronics, we’ve seen that employing humidity controls will preserve quality, and cannabis flower is no different.

Saltwater-based humidity control solutions with two-way vapor-phase osmosis technology automatically add or remove water vapor as needed to maintain a constant, predetermined RH level and ensures a consistent level of moisture weight inside the cannabis flower.

Here’s one more notable finding we discovered in our storage research: Third-party lab tests commissioned by Boveda showed cannabis stored with humidity control had terpene and cannabinoid levels that were 15% higher than cannabis stored without.

Cannabis stored within the optimal humidity range maximizes all the qualities that attract and retain customers. Similar to wine-making, when cannabis cultivators focus on quality control they need to look beyond the harvest.

Gaps in Standard Property Insurance Can be an Unknown Hazard for Cannabis Businesses

By Susan Preston, T.J. Frost

1 Comment

Basic business liability coverage is not enough for those cultivating, selling and distributing cannabis. General liability, property and even commercial renter’s insurance policies all exclude aspects of cannabis operations, leading to significant gaps in coverage.

Unfortunately, many cannabis operations purchase traditional property policies, assuming they’re insured. Then, when a claim comes to light, they find out they’re not covered.Consider the following common exclusions that could lead to a costly business interruption – or worse

Although the production, sales and distribution of cannabis is legal in many U.S. states, it is still illegal federally. This disparity can cause confusion when it comes to insurance compliance. Cannabis companies will want to secure industry specific coverage for risks associated with property, business interruption, and auto as well as general liability.

Consider the following common exclusions that could lead to a costly business interruption – or worse – a shutdown of operations when not properly insured:

Property coverage does not cover crops. Cannabis crops require specific coverage for different growth stages, including seedling, living plant and fully harvested. The insurance industry has designed policies specifically for indoor crop coverage for cannabis operations. There is some market availability for normal insured perils such as fire and theft, to name a few. Work with your broker to review your property policy and any potential exclusions related to cannabis operations. There is currently not much availability for insurance for outdoor crop.
Auto policies exclude cannabis transport. Some states require separate permits for transportation. Review coverage options with a knowledgeable broker before moving forward with driver hiring. Implement driver training sessions on a regular basis, conduct background checks and review MVRs prior to hiring company drivers. Teach drivers how to handle accidents on the scene, including informing law enforcement of the cannabis cargo. Remember that transporting cannabis across state lines (even when legal in both states) is still illegal due to federal law.
Equipment damage and/or breakdown coverage may be excluded from property policies. Consider the expenses and potential loss of revenue due to mechanical or electrical breakdown of any type of equipment due to power surges, burnout, malfunctions and user error. Having the right equipment breakdown insurance will help you quickly get back into full operation, with minimal costs. Conduct an onsite risk assessment of your equipment to get a comprehensive picture of your risk exposure, and review current insurance policies to identify key exclusions.

Organizations looking for cannabis business insurance are best off working with a qualified broker who is knowledgeable in the cannabis space.As the cannabis industry continues to expand, more and more insurance options have become available. And yet as with any fast-paced industry, not every option that appears legitimate is a good risk for your cannabis business.

Be a contentious insurance consumer. Review the policy closely for exclusions and coverage features so you understand the premium rates and limits of the policy. Discuss with your broker the history of the carrier as to paying claims in a timely fashion.

Flooring Tips for Cannabis Growing Facilities

By Sophia Daukus

5 Comments

In the burgeoning cannabis market, grow facilities are facing more and more competition every day. New indoor cultivation enterprises are often being set up in formerly vacant industrial buildings and commercial spaces, while in other cases, companies are planning and constructing new grow facilities from the ground up. For all these establishments, continually lowering production costs while supplying the highest possible quality in ever-increasing yields is the way forward.

Whether in existing or new structures, concrete floors are ubiquitous throughout the majority of cannabis growing facilities. With the right treatment, these indoor concrete traffic surfaces can greatly contribute to a company achieving its operational objectives. Alternatively, insufficiently protected concrete floors can create annoying and costly barriers to accomplishing company goals.

Challenges in Cannabis Grow Facility Construction

As with any emergent industry, mainstream acceptance and market growth is bringing regulation to cannabis cultivation. Local governments are paying more attention to how cannabis growing facilities are constructed and operated. In addition to the standard business matters of building safety, employee working conditions and tax contributions, elected officials are increasingly under pressure from constituents to analyze the overall effect of grow facilities on their communities at large.

High consumption of energy for grow room lights and high water usage are just part of the equation. The temperature and humidity needs of a grow facility can be similar to that of an indoor swimming pool environment. While warmth and moisture are ideal for cannabis growth, they also provide the ideal conditions for the growth and proliferation of fungi and other undesirable microorganisms. Therefore, to help preserve plant health in the moist indoor climate, fumigation often comes into play.

Carbon dioxide (CO2) enrichment of grow room air, a common practice proven to increase crop yields, presents another set of safety and health considerations in dense urban environments.

Adding to these challenges, many cannabis grow facilities are producing plants destined for either pharmacological or nutritional use. This in itself demands scrutiny by regulators for the sake of the consuming public.

As a result, grow room managers and owners must stay informed about the evolution of the industry in terms of local and federal agency regulations concerning their facilities, their overall operation and their products.

Bare Concrete Floors in Grow Rooms

As a foundational construction material, concrete continues to lead the way in commercial and industrial construction. Despite the many advantages of concrete floors, when left unprotected they can present significant challenges specific to cannabis grow rooms.

Untreated, bare concrete is naturally porous, easily absorbing liquids and environmental moisture. Substances found in grow rooms, such as fertilizers, fungicides and other chemicals, can leach through the porous concrete floor slab into the soil and ground water. Whether organic or synthetic, concentrations of such substances can be highly detrimental to the surrounding environment.
Whether in an existing or newly constructed facility, it is not uncommon for the under-slab vapor barrier to be compromised during construction. When this occurs, moisture from the soil beneath the floor slab can enter the concrete and move osmotically upward, creating a phenomenon known as Moisture Vapor Transmission (MVT). The resulting moisture and moisture vapor tends to become ever more alkaline as it rises upward through the concrete slab. MVT can result in blistering, bubbles and other damage to floor coverings.
The warm temperatures, regular watering of plants and high relative humidity maintained within many grow rooms can contribute to a weakening of the structural integrity of unprotected grow room slabs.
Within the confined space of a grow room, the warm, moist air invites microbe proliferation. Food and pharmaceutical plants are high on the priority list when it comes to facility hygiene levels, as demanded by code.

Public health guidelines for cannabis cultivation facilities in various parts of the country are increasingly mirroring those of food processing. Typical requirements include having smooth, durable, non-absorbent floor surfaces that are easily cleaned and in good repair, possessing proper floor slope towards a sanitary floor drain, with no puddling, as well as an integral floor-to-wall cove base. These directives cannot be met with bare concrete alone.

Optimal Grow Room Flooring Performance

In some locations, cannabis growing facilities are already subject to strict building codes and regulations. This will no doubt be spreading to other regions in the near future. For example, the Public Health Agency of Los Angeles County publishes construction guidelines to ensure cannabis facility floors meet standards mirroring the food processing and pharmaceutical manufacturing industries, where sanitation, facility hygiene and safety are paramount. In these types of facilities, bare, unprotected concrete floor slabs are not allowed as a general rule, due to the material’s innate porosity and absorbency.

Flooring in grow rooms, like in their food and pharma industry counterparts, should optimally:

Provide a monolithic and virtually seamless surface to help eliminate crevices, grout lines and other dark, damp locations where soil and pathogens tend to hide
Be impervious and non-porous, providing a surface that can isolate toxic materials on the surface for proper clean-up where needed
Enable correction or improvement of the floor slope for proper drainage, with no low spots to help avoid puddling
Be installed with integral floor-to-wall cove options for easier wash-down and sanitizing
Have the strength and thermal shock resistance, plus the tenacious bond, to undergo steam-cleaning and/or hot power washing, where needed
Enable seamless, continuous surface installation over concrete curbs and containment areas
Offer antimicrobial options for highly sensitive locations
Demonstrate high compressive strength and impact resistance for durability under heavy loads

Display excellent abrasion resistance, allowing the system to perform under grueling daily wear-and-tear
Present customizable slip-resistance options that can be balanced with easy clean-ability
Facilitate the use of floor safety markings, such as color-coded traffic and work area designations

Be formulated with low odor, low-VOC chemistries that meet all EPA and similar regulations
Be able to contribute LEED Green Building Credits, where desired
Include options for refurbishing old or damaged concrete surfaces to allow reuse of existing facility resources, as opposed to having to be demolished, thus unnecessarily contributing to landfill waste
Withstand and perform in continually damp grow room conditions, without degrading
Be compliant with FDA, USDA, EPA, ADA, OSHA, as well as local regulations and/or guidelines
Include MVT mitigating solutions where Moisture Vapor Transmission site issues are present
Provide waterproofing underlayment options for multi-story facilities
Demonstrate excellent resistance to a broad range of chemicals, fertilizers and extreme pH substances

Finding an affordable floor system with all the above features may seem like a tall order. Luckily, innovative manufacturers now offer cannabis facility flooring that meets sanitation, regulatory compliancy, durability and budgetary needs of growers.

Resinous Flooring Value for Cannabis Facilities

Choosing the right floor solutions for a given cultivation facility may be one of the most important decisions an owner or manager makes. Since floors are present throughout the structure, poor selection and compromised protection of concrete slabs can end up wreaking havoc with profits and yields over time.

Few facilities can afford the inconvenience and expense of an otherwise unnecessary floor repair or replacement. Having to suddenly move cumbersome plant beds and heavy pots in order to give workers access to the floor area can be headache. In addition, the unscheduled downtime and overall juggling of resources that invariably must take place make a strong case for investing in optimal grow room flooring from the start.

An excellent long-term value, professional-grade resinous floor systems present cannabis growers with a unique set of solutions for cultivation rooms. Not only does this type of flooring offer all the desirable features listed above, but also furnish a host of added benefits to grow room operations, including:

Very High Gloss Finish

Highly reflective floor surfaces enable light entering the space from overhead to bounce back upward, exposing the underside of leaves to the light and potentially increasing yields
Exceptionally high gloss floor finishes in light colors help make the most of your existing lighting sources, significantly increasing room illumination
Achieving greater illumination without adding fixtures helps reduce energy consumption and associated costs

Virtually Seamless Surface

Fluid-applied resin-based flooring provides an impermeable, monolithic surface that is exceptionally easy to clean and maintain
The virtually seamless finish of resinous coated floors greatly reduces the number of locations for soil, pathogens and microbes to gather
Resinous floors, by incorporating integral cove bases to eliminate ninety degree angles, correcting floor slope to eliminate puddling, and allowing for a virtually seamless surface, provide an optimally sanitary flooring solution

Outstanding Moisture Tolerance

Designed specifically for use in wet industrial environments, cementitious urethane flooring is a top choice for humid grow rooms
Also called “urethane mortar”, this type of floor can help mitigate certain undesirable site conditions, such as Moisture Vapor Transmission (MVT)

Chemical, Acid and Alkali Resistance

Whether organic or synthetic, many soil enhancers and substances used to eradicate undesirable fungi and pests can damage concrete and shorten the usable life of foundational slabs
Protecting concrete slabs with monolithic, non-absorbent and appropriately chemical resistant coating systems allows concrete to perform as designed, for as long as intended
A proper barrier coating on the floor allows spilled or sprayed substances to be properly cleaned up and disposed of, rather than allowing the liquids to seep through the porous slab, and into the surrounding natural environment

Added Safety

Resinous coating systems’ slip-resistance is completely customizable at the time of installation, enabling growers to request more traction in pedestrian walkways and less slip-resistance under raised beds.
Epoxy, urethane and polyaspartic resinous flooring systems accommodate the installation of safety and line markings, as well as varying colors to delineate specific work areas

How to Reduce Mold & Contaminants in Indoor, Greenhouse and Outdoor Grows

Controlling your grow environment doesn’t start when you germinate your first seeds, it starts before you build your grow. There are steps you can take that will have a significant impact on mold growth and contamination, and these will vary based on the grow environment you choose.

Below is a roadmap to where each grow environment stands in terms of mold and contamination risk, and simple steps you can take to mitigate these factors.

Outdoor

The benefits of an outdoor grow are significant – using natural sunlight to grow plants is both inexpensive and environmentally sound. However, it allows the least amount of control and makes plants susceptible to weather conditions and outdoor contaminants including dust, wind, rain and insects. Depending on humidity and precipitation levels, mold can be a big issue as well.

When selecting an outdoor area for a cannabis farm, there are two important factors to consider: location and neighboring farmland. Geographical environments and sub-climates vary and once you have purchased land, you are committed, so be sure to consider these factors prior to purchase.

While arid desert climates have abundant sunlight and long growing seasons, flat, dry lands are subject to dust-storms, flash floods and exceedingly high winds that can damage crops. Conversely, more protected areas often have high humidity and rainfall late in the season, which can create huge issues with bud rot and mold. Neighboring farms also have an impact on your grow, so be sure to find out what they cultivate, what they spray, their harvest schedule and how they run their operation. Large farming equipment kicks up a lot of contaminant-laden dust and can damage crops by displacing insects to your farm if they harvest before you. Pesticide drift is also a major issue as even tiny amounts from a neighbor’s farm can cause your crops to fail testing, depending on what state you are in.

With outdoor grow environments always at the mercy of Mother Nature, any cultivator is wise to control contamination potential on the ground. Cover soil and protect your crop by planting cover crops and laying plastic mulch on as much ground as reasonable. In many cases it makes sense to irrigate uncultivated parts of your farm just to keep dust down.

Greenhouse

Greenhouses are the future of cannabis cultivation. They allow growers to capture the full spectrum and power of the sun while lessening environmental impact and operating expenses, while still being able to precisely control the environment to grow great cannabis. With recent advancements in greenhouse technology such as automated control systems, positive pressure, geothermal heating or cooling and LED supplemental lighting, greenhouses are the future. However, older or economy greenhouses that take in unfiltered air from outside still have a medium amount of mold and contamination risk.

Before building your greenhouse, study the area while taking into account climate, weather conditions and sun exposure. Excessively windy areas can blow in contaminants, and extremely hot climates make cooling the greenhouse interior a challenging and costly endeavor.

There are several simple operational tactics to reduce contaminants in a greenhouse. Add a thrip screen to keep insects out, thoroughly clean pad walls with an oxidizing agent after each cycle, and keep plants at least 10 feet from pad walls. Plan to flip the entire greenhouse at once so that you can clean the greenhouse top to bottom before your next crop. A continuous harvest in your greenhouse allows contaminants to jump from one plant to the next and reduces the ability to control your environment and eliminate problems at the end of a cycle. Lastly, open shade curtains slowly in the morning. This prevents temperature inversion and condensation, which can cause water drops to fall from the ceiling and transfer contaminants onto plants below.

Indoor

An indoor environment offers ultimate control to any grow operation. Cultivators can grow high-quality cannabis with the smallest potential for yeast and mold growth. Unfortunately, indoor environments are extremely expensive, inefficient and environmentally costly.

With indoor grow environments, keeping mold and contaminants at bay comes down to following a regimented plan that keeps all grow aspects clean and in order. To keep your grow environment clean, change HVAC filters multiple times a month. It’s also important to install HEPA filters and UV lights in HVAC systems to further reduce contamination threats. Clearly mark air returns if they are near the ground and keep those areas free of clutter. They are the lungs of your grow. Also, stop using brooms in the grow space. They stir up a lot of contaminants that have settled to the floor. Instead, use HEPA filter backpack vacuums or install a central vacuum system. Set up a “dirty room” for anything messy on a separate HVAC system, and be sure to thoroughly clean pots after every harvest cycle.
