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

By Ingo Mueller

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

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

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

Compounding Risks

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

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

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

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

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

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

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

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

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

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

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

Integrated Labeling Helps This Ohio Cannabis Company Grow

By Mike Barker

No Comments

Since medical cannabis was legalized in Ohio in 2016, companies that cultivate and process medical cannabis, as well as the plants themselves, have been popping up around the state.

Grow Ohio, a dual-licensed Level 1 cultivator and processor, was the first licensed processor in Ohio and the first to successfully bring product to market. From plant material to edibles, tinctures, oils, lotions and capsules, the company seeks to ensure that medical cannabis is cultivated and processed under the same strict standards as any pharmaceutical medication. As first to market, Grow Ohio found themselves navigating a complicated process by themselves.

As their first product was ready to be packaged, Executive Vice President (EVP) Justin Hunt and the team at Grow Ohio were focused on marketing, packaging and distributing their product. With the sheer number of items that required attention, it is easy to see how something like labelling can slip under the radar. With a variety of products and dosages, and the first delivery of the product slated for late April of 2019, Grow Ohio needed a consistent way to ensure their product complied with state law, and also satisfied their own brand standards.

As their April product launch date grew closer, Grow Ohio realized they needed help with executing on Ohio’s labeling requirements for medical cannabis products.

They turned to Adaptive Data Inc., a barcode and labeling systems supplier to provide labels, printers, and software. ADI’s task was to specify the right label materials for their branding and compliance needs and provide software and equipment to print compliance labels on demand. ADI’s proposed solution would slash the waste associated with printing and applying labels and create a lean process.

Compliance

Compliance labels must contain specific information and must be prominently visible and clearly legible. Containers have to be labeled with details including the specific quantity of product, dosage, THC levels, license #, testing lab name and ID #, and other details. Different sizes and shapes are required for the various packaging form factors.

Due to the large amount of content and a relatively small label area, ADI specified 300 dpi printer resolution so that 4 or 5 point fonts would be legible.

Hunt had all the information needed to comply with state regulations, but didn’t have a way to get that information, properly formatted, onto a finished label at the point of packaging. “It’s all about how you get the data from one source to the other in a way that is easily repeatable,” says Hunt. The solution provides the capability to handle all compliance requirements, for all types of product and all sizes/shapes of labels. The system is designed to minimize key entry of data, a typical source of content errors. All of Grow Ohio’s products contain THC and require the red THC compliance logo. Early on this requirement was met using a separate, hand-applied THC logo label, which was very costly. The labels now include the THC logo, all required compliance data, and the capability to include a 2d barcode.

At the time the products are packaged all compliance information is printed on demand with label printers. As retail expansion continues, the barcode on the plant material compliance label can be used with the POS systems of the dispensaries, to keep their systems fast and accurate.

Until the system is ready to receive data automatically from METRC, the State approved inventory system which tracks all medical cannabis plants and products grown or produced in Ohio, they used user interfaces that reduce the amount of data that is key entered to an absolute minimum. Using drop down lists, date pickers and calculated results, means that Grow Ohio only enters data in 5-10 fields, depending on product line. As the system evolves the next step will be to take data for compliance details automatically from METRC.

Branding

As the first to enter the medical marijuana market, Grow Ohio leadership knew that their brand image is as important to their success as the quality of their products. Their logo, color choice, and inclusion of the THC logo had to be consistent in appearance across all products, regardless of production method. They used full color branded product labels and blank labels that have the Grow Ohio and THC logo pre-printed. (Compliance data is added to the blank labels on demand.)

Label Application – Automatic, Semi-automatic and Manual

Grow Ohio packages in metal cans, glass bottles and in boxes. Each packaging type has specific requirements.

Metal Cans: Grow Ohio uses an automated packaging line for plant material in cans. That line includes two automatic apply-only machines (for brand labels). The compliance label is printed and dispensed and placed on the can as it is boxed.

Bottles: Cylindrical containers can be difficult to label. Grow Ohio originally packaged tinctures and oils in glass bottles which were pre-printed with their logo. The printed logo looked nice, but printing on the glass was expensive. This made placing the compliance label on the bottle more difficult, since the logo could not be covered. Positioning and straightness was critical for readability as well as aesthetics. Manual placement was time consuming (15 – 30 seconds per bottle).

Now, bottles are being processed with the help of a semi-automatic print-apply machine. The print-apply machine can label 18-20 bottles per minute.

By using plain bottles and pre-printing the blue Grow Ohio logo and red THC logo on the label, they were able to streamline the process. The semi-automatic print-apply machine adds the compliance data to the label and applies the label to the bottle.

The result is a lower total cost of the product. Plain bottles cost less without the logo and the labor to manually apply the labels has been greatly reduced. In addition, with the logos on the label instead of the bottle, orientation and spacing are no longer an issue. The label maintains the natural brand feel, which was important to Hunt.

Boxes: Only compliance labels are required for boxes as the branding information is pre-printed on the box. Compliance labels for boxes include a pre-printed, red THC logo. The printer prints the compliance data and presents the label with the liner removed, ready to be manually applied to the box.

Summary

With a broad product line, Grow Ohio’s label requirements are quite diverse. By specifying and sourcing the right hardware, software and label materials,

Adaptative Data provided an efficient, repeatable, cost-effective way to do brand and compliance labeling for Grow Ohio’s diverse product offering.

Hunt now understands the magnitude of work that goes into coming up with a compliant, cost-friendly compliance labeling approach – an appreciation he did not have at the outset. He is not alone in this regard as many companies come to this understanding late in the start-up process.

Hunt isn’t sure how fast the market will grow, but he is not worried. As the market expands and demand grows, he knows his systems can handle it.

Alcaliber Spinoff Linneo Health Gets Greenhouse GMP Certification In Spain

By Marguerite Arnold

No Comments

As the industry faces what is undoubtedly a watershed moment for the international cannabis vertical, a new Spanish firm steps into the market with its own EU GMP certification license. Linneo Health is also helmed by the ever eloquent and highly experienced Jose Antonio de la Puente – a tall drink of water with a conscience, a brain and an admirable mission statement.

As Cannabis Industry Journal broke in our last story, a lack of international standards in Europe have been on trial of late. The same day that the CannTrust scandal began to blow in Canada and as Danish authorities rang global alerts, the only qualified packager in Holland was issued a new EU GMP cert. That is a government decision, not a commercial one.

This also implies, at minimum, government lack of coordination and agreement on EU GMP cert even between European nations, for a nascent industry while also trying to avoid the thorny issue of patient home grow. See also the trials and travails of the erstwhile German cultivation bid and its reconstituted Frankenstein-esque bigger if younger sister. In fact, this contretemps is almost certainly involved if not indirectly to blame.

Not All Is Entirely Rosy On Cannabis Europe’s Eastern Front

Almost simultaneously to Linneo Health’s announcement, however, the news came that in Poland, authorities had suspended the pending product registration process. Will this be on hold until after the October election?

In this environment it is almost impossible to know.

Here is one thing to consider. These almost simultaneous developments in Spain and Poland and the newest announcement about further certification of the Dutch recreational system under a new pending “recreational trial” are almost directly related.

That said, even such political maneuverings are not new – and far from limited to any single company. Both Germany and Poland have been wracked by reform stuttered by short term gain and market entry strategies executed by most of the biggest players in the room. Aurora, for example, announced their first import into Poland the same day the Polish government changed the law last fall. Aurora uses Germany as its breakpoint distribution center for Europe.

A Stamp of Authenticity That Is Sorely Needed

Beyond the pharma and market entry politics, however, this Alcaliber-helmed project creates a ring of authority to the same that creates at least one cannabis brand the European medical community can see the certification for.

For now at least, certainly among the ranks of the upper echelons of the international cannabis industry, there must surely be a sigh of relief.

EU GMP certifications (in other words, the authorization to produce product bound for a medical, pharma market) do not happen overnight. On the European front, this is surely at least a step in the right direction for an industry embattled by scandals, particularly of the securities, production, certification and accounting kind right now.

In this case, however, it is also clear that no matter the egregious oversteps and potentially illegal and certainly dubious behaviour of some members of the industry, there are also clearly those within it, and at high levels, who have tried to do the right thing. And further, from the beginning of the nascent industry here as of 2015.

Who Is Alcaliber?

Alcaliber is one of the world’s largest opioid manufacturers. Unlike American counterparts, the company decided several years ago to invest in and back ideas of the opioid-to-cannabinoid therapy model. Linneo Health is a 60% subsidiary of Alcaliber and 40% owned by a Spanish family office called Torreal, S.A.

This is, as a result, one of the most important GMP licenses in Europe at the moment if not the world. It means that within a pharmaceutical environment, the first widespread research and production of plants and therapies for those suffering from both chronic pain, plus neurological and oncological conditions that cause or are related to the same, will be put on a fast track long in the offing. Certainly in Europe.

And that for one, is a positive development that will have widespread implications elsewhere. Particularly given the news that the opioid epidemic in the United States finally has a name, and culpable parties.

What Else Is Unusual About This Project?

GMP certification is a vastly misunderstood concept at the moment. It is also a highly thorny one because of a still standardizing set of agreements. The regulatory environment is in place, in other words, but there are many, many gaps, as well as shifting rules and underlying treaties.

However, on top of this, there is also an amazing lack of innovation in interpretation, in part because of many misadvised consultants who are actually seeking to “save” production costs for their clients, or because they do not know any better. Or because producers are scared of doing the wrong thing.

The new project in Spain is unusual because it is a greenhouse grow that got EU GMP cert – although look for more of this in the future. It means that with careful, standardized, pharma production, not all regulated cannabis grows, even for the medical market, have to use huge amounts of energy in repurposed post-industrial developments. It is also certainly cleaner than growing outside. And, when done right, saves huge amounts of water.

Cleantech, in other words, has finally hit the cannabis industry in Europe. As well as a pharmaceutical company invested in the cannabinoid treatment of (at least) chronic pain.

That is an overdue and hugely positive development. No matter what else can be said for shenanigans engulfing the rest of the industry at the moment.

Fungal Monitoring: An Upstream Approach to Testing Requirements

By Bernie Lorenz, PhD

1 Comment

Mold is ubiquitous in nature and can be found everywhere.¹ Cannabis growers know this all too well – the cannabis plant, by nature, is an extremely mold-susceptible crop, and growers battle it constantly.

Of course, managing mold doesn’t mean eradicating mold entirely – that’s impossible. Instead, cultivation professionals must work to minimize the amount of mold to the point where plants can thrive, and finished products are safe for consumption.

Let’s begin with that end in mind – a healthy plant, grown, cured and packaged for sale. In a growing number of states, there’s a hurdle to clear before the product can be sold to consumers – state-mandated testing.

So how do you ensure that the product clears the testing process within guidelines for mold? And what tools can be employed in biological warfare?

Mold: At Home in Cannabis Plants

It helps to first understand how the cannabis plant becomes an optimal environment.

The cannabis flower was designed to capture pollen floating in the air or brought by a pollinating insect.

Once a mold spore has landed in a flower, the spore will begin to grow. The flower will continue to grow as well, and eventually, encapsulate the mold. Once the mold is growing in the middle of the flower, there is no way to get rid of it without damaging the flower.

A Name with Many Varieties

The types of spores found in or around a plant can make or break whether mold will end with bad product.

Aspergillus for example, is a mold that can produce mycotoxins, which are toxic to humans². For this reason, California has mandatory testing³for certain aspergillus molds.

Another example, Basidiospores, are found outside, in the air. These are spores released from mushrooms and have no adverse effects on cannabis or a cannabis cultivation facility.

Fungi like powdery mildew and botrytis (PM and Bud Rot) typically release spores in the air before they are physically noticed on plants. Mold spores like these can survive from one harvest to the next – they can be suspended in the air for hours and be viable for years.

How Mold Travels

Different types of spores – the reproductive parts of mold – get released from different types of mold. Similar to plants and animals, mold reproduces when resources are deemed sufficient.

The opposite is also true that if the mold is under enough stress, such as a depleting nutrient source, it can be forced into reproduction to save itself.⁴

In the end, mold spores are released naturally into the air for many reasons, including physical manipulation of a plant, which, of course, is an unavoidable task in a cultivation facility.⁵

Trimming Areas: A Grow’s Highest Risk for Mold

Because of the almost-constant physical manipulation of plants that happen inside its walls, a grow’s trimming areas typically have the highest spore counts. Even the cleanest of plants will release spores during trimming.

These rooms also have the highest risk for cross contamination, since frequently, growers dry flower in the same room as they trim. Plus, because trimming can be labor intensive, with a large number of people entering and leaving the space regularly, spores are brought in and pushed out and into another space.

The Battle Against Mold

The prevalence and ubiquitous nature of mold in a cannabis facility means that the fight against it must be smart, and it must be thorough.

By incorporating an upstream approach to facility biosecurity, cultivators can protect themselves against testing failures and profit losses.

Biosecurity must be all encompassing, including everything from standard operating procedures and proper environmental controls, to fresh air exchange and surface sanitation/disinfection.

One of the most effective tactics in an upstream biosecurity effort is fungal monitoring.

Ways to Monitor Mold

Determining the load or amount of mold that is in a facility is and always will be common practice. This occurs in a few ways.

Post-harvest testing is in place to ensure the safety of consumers, but during the growing process, is typically done using “scouting reports.” A scouting report is a human report: when personnel physically inspect all or a portion of the crop. A human report, unfortunately, can lead to human error, and this often doesn’t give a robust view of the facility mold picture.

Another tool is agar plates. These petri dishes can be opened and set in areas suspected to have mold. Air moves past the plate and the mold spores that are viable land on the dishes. However, this process is time intensive, and still doesn’t give a complete picture.

Alternatively, growers can use spore traps to monitor for mold.

Spore traps draw a known volume of air through a cassette.⁶The inside of the cassette is designed to force the air toward a sticky surface, which is capable of capturing spores and other materials. The cassette is sent to a laboratory for analysis, where they will physically count and identify what was captured using a microscope.

Spore trap results can show the entire picture of a facility’s mold concerns. This tool is also fast, able to be read on your own or sent to a third party for quick and unbiased review. The information yielded is a useful indicator for mold load and which types are prevalent in the facility.

Spore Trap Results: A Story Told

What’s going on inside of a facility has a direct correlation to what’s happening outside, since facility air comes infromthe outside. Thus, spore traps are most effective when you compare a trap inside with one set outside.

When comparing the two, you can see what the plants are doing, view propagating mold, and understand which of the spore types are only found inside.

Similar to its use in homes and businesses for human health purposes, monitoring can indicate the location of mold growth in a particular area within a facility.

These counts can be used to determine the efficacy of cleaning and disinfecting a space, or to find water leaks or areas that are consistently wet (mold will grow quickly and produce spores in these areas).

Using Spore Traps to See Seasonality Changes, Learn CCPs

Utilizing spore traps for regular, facility-wide mold monitoring is advantageous for many reasons.

One example: Traps can help determine critical control points (CCP) for mold.

What does this look like? If the spore count is two times higher than usual, mitigating action needs to take place. Integrated Pest Management (IPM) strategies like cleaning and disinfecting the space, or spraying a fungicide, are needed to bring the spore count down to its baseline.

For example, most facilities will see a spike in spore counts during the times of initial flower production/formation (weeks two to three of the flower cycle).

Seasonal trends can be determined, as well, since summer heat and rain will increase the mold load while winter cold may minimize it.

Using Fungal Monitoring in an IPM Strategy

Fungal monitoring – especially using a spore trap – is a critical upstream step in a successful IPM strategy. But it’s not the only step. In fact, there are five:

Identify/Monitor… Using a spore trap.
Evaluate…Spore trap results will indicate if an action is needed. Elevated spore counts will be the action threshold, but it can also depend on the type of spores found.
Prevention…Avoiding mold on plants using quality disinfection protocols as often as possible.
Action…What will be done to remedy the presence of mold? Examples include adding disinfection protocols, applying a fungicide, increasing air exchanges, and adding a HEPA filter.
Monitor…Constant monitoring is key. More eyes monitoring is better, and will help find Critical Control Points.

Each step must be followed to succeed in the battle against mold.

Of course, in the battle, there may be losses. If you experience a failed mandatory product testing result, use the data from the failure to fix your facility and improve for the future.

The data can be used to determine efficacy of standard operating procedures, action thresholds, and other appropriate actions. Plus, you can add a spore trap analysis for pre- and post- disinfection protocols, showing whether the space was really cleaned and disinfected after application. This will also tell you whether your products are working.

Leveraging all of the tools available will ensure a safe, clean cannabis product for consumers.

Tips to Shrink your Shrinkage

By Carl Silverberg

No Comments

I had dinner last night with a friend who is a senior executive at one of the largest automobile companies in the world. When I explained the industry-accepted rate of 25-30% shrinkage in horticulture he said, “Are you kidding me? Can you imagine the story in the Wall Street Journal if I gave a press conference and said that we were quite content to throw away three out of every ten cars we manufactured?”

Yet, for all growers, operators and investors who complain about shrinkage, it’s an accepted part of the business. What if it wasn’t; what if you could shrink your shrinkage by 60% and get it down to 10% or less? How much more profitable would your business be and how much easier would your life be?

Let’s take the floriculture industry as our first example. You propagate chrysanthemums in February, they get repotted at the end of April and by the end of June, you might start to see some buds. In a very short time span your job changes from being a grower who manages 10,000 square feet of chrysanthemums to being an order taker. Over a period of eight weeks, you have to unload as many of those mums as possible. The sales team at Macy’s has more time to move their holiday merchandise than you do.

If you’re like most operations, your inventory tracking system consists of Excel spreadsheets and notebooks that tell you what happened in previous years so you can accurately predict what will happen this year. The notebooks give you a pretty accurate idea of where in the greenhouses your six cultivars are, how many you planted and which of the five stages they are in. You already have 30 different sets of data to manage before you add on how many you sell of each cultivar and what stage they were in.

The future of the industry is making data-driven decisions that free up a grower to focus on solving problems, not looking for problems.Then your first order comes in and out the window goes any firm control of where the mums are, what stage they’re in and how many of each cultivar you have left. A couple of hours after your first order, a second comes in and by the time you get back in touch, check your inventory, call back the buyer and she’s able to connect with you, those 2837 stage 3 orange mums are moving into stage 4. Only she doesn’t want stage 4 mums she only wants stage 3 so now you frantically call around to see who wants stage 4 orange mums very soon to be stage 5 mums.

And, the answer is often no one. What if you didn’t have your inventory count exact and now you have 242 yellow mums that you just found in a different location in your greenhouse and had you known they were there, you could have sold them along with 2463 other mums that you just located in various parts of your greenhouse.

It doesn’t have to be like that. We had a client in a similar situation, and they are on track to reduce their shrinkage to just a shade over 10%. The future of the industry is making data-driven decisions that free up a grower to focus on solving problems, not looking for problems.

And don’t think that shrinkage is an issue only in the purview of floriculture. It’s an even bigger problem for cannabis because of the high value of each crop. The numbers don’t sound as bad because unlike floriculture, you don’t have to throw out cannabis that’s not Grade A. You can always sell it for extract. But extract prices are significantly less per pound than flower in the bag.

Here’s how one grower explained it. “Because of the high value of the crop, and the only other crop I’ve worked with that high is truffles, you’re playing a much higher stakes game with shrinkage. Even if you try and salvage a bad crop by using all of the parts of the cannabis plant. Listen, the difference between Grade A and Grade C could be $1,000 for A while a pound of B/C is less than $400. If you produce a standard 180 to 200 pounds in your grow rooms, you’ve really screwed up. No operator is going to keep you if you just cost them $120,000.”

California Banned Ozone Generator “Air Purifiers”

By Jeff Scheir

8 Comments

California was the first state to step up to defend consumers from false marketing claims that ozone generators are safe, effective air purifiers. In reality, ozone is a lung irritant, especially harmful to allergy and asthma sufferers. In 2009, California became the first state in the nation to ban ozone generators. The Air Resources Board of the California Environmental Protection Agency states:

Not all air-cleaning devices are appropriate for use — some can be harmful to human health. The ARB recommends that ozone generators, air cleaners that intentionally produce ozone, not be used in the home or anywhere else humans are present. Ozone is a gas that can cause health problems, including respiratory tract irritation and breathing difficulty.

The regulation took effect in 2009 along with a ban on the sale of air purifiers that emit more than 0.05 parts per million of ozone. The ARB says that anything beyond this is enough to harm human health; however, some experts say that there is no safe level of ozone.

The National Institute for Occupational Safety and Health recommends an exposure limit to ozone of 0.1 ppm and considers levels of 5 ppm or higher “immediately dangerous to life or health.”

If you’re shopping for an air purifier, it’s best to avoid ozone generators, especially if you have a respiratory condition. Ozone generators, and ionic air cleaners that emit ozone, can cause asthma attacks in humans while doing little to nothing to clean the air.

O3 is a free radical, an oxidizer; when it meets any organic molecule floating around it bonds to it and destroys it. In a grow room, organic molecules include the essential oils in cannabis which produce the fragrance. When using ozone within your grow room, too much will not only all but eliminate the smell of your flowers but with prolonged exposure, it begins to actually degrade the cell walls of trichomes and destroy the structure of the glands.

Despite the claims of some manufacturers, ozone does not have an anti-microbial effect in air unless levels far exceed the maximums of the regulation and is therefore harmful humans.

Keeping the grow room clean of mold and bacteria is important, but ozone is not the technology you want to employ to satisfy this goal. Looking into a combination of UVC and Filtration will better meet the goal while keeping both your plants and staff healthy.

How Much Cannabis Astroturfing Is Afoot In The UK?

By Marguerite Arnold

1 Comment

Astroturfing is the practice, in political messaging and campaigns, of creating what seems to be a legitimate, grassroots inspired campaign that is actually bought and paid for by an industry lobby or other corporate interests.

It is also clear that this practice is now entering the cannabis space, certainly in the UK.

How and Where?

On August 1, the British Conservative Drug Policy Reform Group sent out a group email entitled “Strategic litigation on medical cannabis access in the UK.” The email, from the group’s senior communications manager, was to announce the kick-off of a crowdfunding campaign to defend a cannabis patient.

It’s beneficiary? A British female MS patient, Lezley Gibson, now facing prosecution for growing her own cannabis after being unable to afford what was on offer at her local pharmacy.

Here is the first flag: MS is the only condition for which Sativex (manufactured by British firm GW Pharma) is prescribed on label (in other words without special approvals).

The problem is that the NHS (along with most of the German statutory approvers) feels that Sativex is still too expensive and not effective enough. And that problem won’t be solved with either patient home grow access or a lawsuit to gain that right, but rather funded trials.

However, more disturbingly, the email referenced the supposed success of a similar legal tactic in Germany several years ago. This is to say it used a highly inaccurate analogy. In Germany, a male chronic pain patient sued the government for the right to grow his own cannabis. He won the right temporarily, but this was taken away from him after the law changed in March 2017. Now he, like every other cannabis patient in Germany, must get his cannabis from a pharmacy. German patients also must get their initial prescription approved by health insurers – which is for everyone – but particularly non MS patients – the biggest fight in the room right now on the topic of medical efficacy.

Further, the right to grow one’s own medical cannabis, no matter the condition suffered, has been removed from patients in every legal jurisdiction where there is no constitutional right to it first – namely patients sue for the same.

As such, it is entirely conceivable that as a “strategic” case, this is more likely to put pressure on the NHS to pay the sky-high price of Sativex for MS patients (which it has already refused to do) than create any other kind of access for anyone else.

When contacted by Cannabis Industry Journal, a CDPRG spokesperson said that the patient had given her support for the crowdfunding campaign and needed help.

piechart — Most German Patients Are Still Only Getting Dronabinol

However, there are other issues here. Namely that when selecting a strategic case (no matter how harsh this sounds to the individual patient), the entire discussion at this point – certainly from an efficacy point of view, might be better served with supporting the case of a patient who has less access because of either physical condition or economic status.

In fact, in Germany so far, thanks to the change in the law that the British group references, while there certainly are tens of thousands of cannabis patients at the moment (including many MS patients), the majority of them receive Dronabinol or Sativex. And all of them have to fight for medical access and approval from their insurers. That is of course, when they can find a doctor to prescribe in the first place. There are also estimates that there are close to a million patients in Germany who cannot get access, thanks to the change in the law created by one patient’s law suit.

Is this flavour of litigatious advocacy now afoot in the UK, in other words, the kind of lawsuit that is designed to benefit the industry more than patients looking for affordable, home-grown, if regulated product?

Astroturfing Cannabis Issues Under Brexit Colors?

No matter the real versus stated intent of the instigators of the Gibson case, or the eventual outcome of such litigation, there is no doubt that cannabis is being brought into larger political debates. And further, no surprise, “patient access” is an issue just as ripe for “issue manipulation” and astroturfing as anything else.

“Strategic” if not “crowdfunded” cause or tactical lawsuits are another form of this technique.

That foreign cannabis money is already in the room is also no surprise. The British press was alight with stories during June of the amount of money contributed to the CDPR Group from Canadian sources.

Seen within the context of Brexit itself, this is disturbing locally.There are other issues involved in this kind of challenge to the law.

Not to mention the fact that in May, none other than Arron Banks, the self-styled backer of the Leave Campaign, decided, suddenly, to throw his hat into the CBD oil ring on Twitter. Not to mention repeated the same information repeatedly, including his $4 million investment into the space during the following months so far. Plus, of course, wildly optimistic valuations of the U.S. market.

Suing For Patient Justice Or A Backdoor For Canadian and Other Corporate Interests?

There are other issues involved in this kind of challenge to the law.

The first is that in the British case this is actually not a constitutional case per se, but a human rights one. See the problems that those who are trying to define the British constitution right now on other matters (see Brexit) are running into.

The second is that while the patient in question in this case (Ms. Gibson) is undoubtedly relieved at the prospect of a legal defence for growing her own medication in the face of insurmountable cost, on the “positive” side, her case is unlikely to do much more than make impoverished patients fight NHS paperwork if they can find a doctor. See Germany, as a prime example.This lawsuit, in other words, no matter how it might get one woman out of a terrible legal situation, is not necessarily “pro-patient.”

But what it will do is something else. It may well remove the current widespread prohibition on the harvesting of cannabis flower in the UK. And while patients would face again being moved into the slow lane of NHS approvals (with lots of fights over efficacy looming and still unsolved), corporate growers and processors if not importers, already investing millions into such efforts across the UK and Ireland, benefit.

At the exclusion, also, as has been the case in Germany, of local producers who are not already large corporate interests or existing farms.

This lawsuit, in other words, no matter how it might get one woman out of a terrible legal situation, is not necessarily “pro-patient.” It also may well do everything to frustrate, slow down and further complicate medical access for those at the end of the chain, while only opening up “investment opportunities” for large companies and well-heeled interests who have nothing but profit, if not the destruction of the NHS in mind.

Keeping Your Environment Clean: Preventative Measures Against Contamination

By Jeff Scheir

2 Comments

For years we have heard about and sometimes experienced, white powdery mildew when growing cannabis. It is a problem we can see, and we have numerous ways to combat it. But now more and more states are introducing regulatory testing on our harvests and they are looking for harmful substances like Escherichia coli., Aspergillis Fumigatus, Aspergillis terreus, … just to name a few. Mycotoxins, mold and bacteria can render a harvest unusable and even unsellable- and you can’t see these problems with the naked eye. How much would it cost you to have to throw away an entire crop?

You bring in equipment to control the humidity. You treat the soil and create just the right amount of light to grow a superior product. You secure and protect the growing, harvesting, drying and production areas of your facility. You do everything you can to secure a superior yield… but do you?

Many of the organisms that can hurt our harvest are being multiplied, concentrated and introduced to the plants by the very equipment we use to control the growing environment. This happens inherently in HVAC equipment.

Your air conditioning equipment cools the air circulating around your harvest in a process that pulls moisture from the air and creates a perfect breeding ground in the wet cooling coil for growth of many of the organisms that can destroy your yield. As these organisms multiply and concentrate in the HVAC system, they then spew out into the very environment you are trying to protect at concentrated levels far greater than outside air. In effect, you are inoculating the very plants you need to keep safe from these toxins if you want to sell your product.

The cannabis industry is starting to take a page from the healthcare and food safety industries who have discovered the best way to mitigate these dangers is the installation of a proper UVC solution inside their air conditioning equipment.

Why? How does UVC help? What is UVC?

What is Ultraviolet?

Ultraviolet (UV) light is one form of electromagnetic energy produced naturally by the sun. UV is a spectrum of light just below the visible light and it is split into four distinct spectral areas – Vacuum UV or UVV (100 to 200 nm), UVC (200 to 280 nm), UVB (280 to 315 nm) and UVA (315 to 400 nm). UVA & UVB have been used in the industry to help promote growth of cannabis.

What is UVC (Ultraviolet C)?

The entire UV spectrum can kill or inactivate many microorganism species, preventing them from replicating. UVC energy at 253.7 nanometers provides the most germicidal effect. The application of UVC energy to inactivate microorganisms is also known as Germicidal Irradiation or UVGI.

UVC exposure inactivates microbial organisms such as mold, bacteria and viruses by altering the structure and the molecular bonds of their DNA (deoxyribonucleic acid). DNA is a “blue print” these organisms use to develop, function and reproduce. By destroying the organism’s ability to reproduce, it becomes harmless since it cannot colonize. After UVC exposure, the organism dies off leaving no offspring, and the population of the microorganism diminishes rapidly.

Ultraviolet germicidal lamps provide a much more powerful and concentrated effect of ultraviolet energy than can be found naturally. Germicidal UV provides a highly effective method of destroying microorganisms.

To better understand how Steril-Aire UVC works, it is important to understand the recommended design. Directed at a cooling coil and drain pan, UVC energy destroys surface biofilm, a gluey matrix of microorganisms that grows in the presence of moisture. Biofilm is prevalent in HVAC systems and leads to a host of indoor air quality (IAQ) and HVAC operational problems. UVC also destroys airborne viruses and bacteria that circulate through an HVAC system and feed out onto the crop. HVAC cooling coils are the largest reservoir and amplification device for microorganisms in any facility.

For the most effective microbial control, UV germicidal Emitters are installed on the supply side of the system, downstream from the cooling coil and above the drain pan. This location provides more effective biofilm and microbial control than in-duct UVC installations. By irradiating the contaminants at the source – the cooling coils and drain pans – UVC delivers simultaneous cleaning of surface microorganisms as well as destruction of airborne microorganisms and mycotoxins. Steril-Aire patented this installation configuration in 1998.

The recirculating air in HVAC systems create redundancy in exposing microorganisms and mycotoxins to UVC, ensuring multiple passes so the light energy is effective against large quantities of airborne mycotoxins and cleaning the air your plants live by.

Where are these mycotoxins coming from?

Aspergillus favors environments with ample oxygen and moisture. Most pre-harvest strategies to prevent these mycotoxins involve chemical treatment and are therefore not ideal for the cannabis industry.

Despite the lack of cannabis protocols and guidelines for reducing mycotoxin contamination, there are some basic practices that can be utilized from other agricultural groups that will help avoid the production of aflatoxins and ochratoxins.

When guidelines are applied correctly to the cannabis industry, the threat of aflatoxin and ochratoxin contamination can be significantly reduced. The place to start is a clean air environment.

Design to win

The design of indoor grow rooms for cannabis is critical to the control of airborne fungal spores and although most existing greenhouses allow for the ingress of fungal spores, experience has shown that they can be retrofitted with air filters, fans, and UVC systems to make them relatively free of these spores. Proper designs have shown clearly that:

Prevention via air and surface disinfection using germicidal UVC is much better than chemical spot treatment on the surface of plants
High levels of air changes per hour enhance UVC system performance in reducing airborne spores
Cooling coil inner surfaces are a hidden reservoir of spores, a fertile breeding ground and constitute an ecosystem for a wide variety of molds. Continuous UVC surface decontamination of all coils should be the first system to be installed in greenhouses to reduce mildew outbreaks.

UVC can virtually eliminate airborne contaminants

Steril-Aire was the first and is the market leader in using UVC light to eliminate mold and spores to ensure your product will not be ruined or test positive.

Mold and spores grow in your air handler and are present in air entering your HVAC system.
Steril-Aire UVC system installs quickly and easily in your existing system.
The Steril-Aire UVC system destroys up to 99.999% of mold/spores.
Plants are less likely to be affected by mold…with a low cost and no down time solution.

It’s time to protect your harvest before it gets sick. It’s time to be confident your yield will not test positive for the contaminants that will render it unusable. It’s time to win the testing battle. It’s time for a proper UVC solution to be incorporated throughout your facilities.

Environmental Sustainability in Cultivation: Part 3

By Carl Silverberg

No Comments

Part 1 in this series went into a discussion of resource management for cannabis growers. Part 2 presented the idea of land use and conservation. In Part 3 below, we dive into pesticide use and integrated pest management for growers, through an environmental lens.

Rachel Carson’s book Silent Spring in 1962, is often credited with helping launch the environmental movement. Ten years later, VP Edmund Muskie elevated the environment to a major issue in his 1972 Presidential campaign against Richard Nixon. 57 years after Ms. Carson’s book, we’re still having the same problems. Over 13,000 lawsuits have been filed against Monsanto and last month a jury in Alameda County ruled that a couple came down with non-Hodgkin’s lymphoma because of their use of Roundup. The jury awarded them one billion dollars each in punitive damages. Is there a safer alternative?

“Effectively replacing the need for pesticides, we use Integrated Pest Management (IPM) which is a proactive program designed to control the population of undesirable pests with the use of natural predators, a system commonly known as “good bugs (such as ladybugs) fighting bad bugs”, states the website of Mucci Farms, a greenhouse grower. While this applies to cannabis as well, there is one major problem with the crop that isn’t faced by other crops.

While states are moving rapidly to legalize it, the EPA is currently not regulating cannabis. That is in the hands of each state. According to a story in the Denver Post in 2016, “Although pesticides are widely used on crops, their use on cannabis remains problematic and controversial as no safety standards exist.” Keep in mind that it takes a lot more pesticides to keep unwarranted guests off your cannabis plant when it’s outdoors than when it’s in a controlled environment.

We’re accustomed to using endless products under the assumption that a range of governmental acronyms such as NIH, FDA, OSHA, EPA, USDA are protecting us. We don’t even think about looking for their labels because we naturally assume that a product we’re about to ingest has been thoroughly tested, approved and vetted by one of those agencies. But what if it’s not?

Again, cannabis regulation is at the state level and here’s why that’s critical. The budget of the EPA is $6.14 billion while Colorado’s EPA-equivalent agency has a budget of $616 million. According to the federal budget summary, “A major component of our FY 2019 budget request is funding for drinking water and clean water infrastructure as well as for Brownfields and Superfund projects.” In short, federal dollars aren’t going towards pesticide testing and they’re certainly got going towards a product that’s illegal at the federal level. That should make you wonder how effective oversight is at the state level.

What impact does this have on our health and what impact do pesticides have on the environment? A former Dean of Science and Medical School at a major university told me, “Many pesticides are neurotoxins that affect your nervous system and liver. These are drugs. The good news is that they kill insects faster than they kill people.” Quite a sobering thought.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”Assuming that he’d be totally supportive of greenhouses, I pushed to see if he agreed. “There’s always a downside with nature. An enclosure helps you monitor access. If you’re growing only one variety, your greenhouse is actually more susceptible to pests because it’s only one variety.” The problem for most growers is that absent some kind of a computer vision system in your greenhouse, usually by the time you realize that you have a problem it’s already taken a toll on your crop.

Following up on the concept of monitoring, I reached out to Dr. Jacques White, the executive director of Long Live the Kings, an organization dedicated to restoring wild salmon in the Pacific Northwest. Obviously, you can’t monitor access to a river, but you certainly can see the effects of fertilizer runoff, chemicals and pesticides into the areas where fish live and eventually, return to spawn.

“Because salmon travel such extraordinary long distances through rivers, streams, estuaries and into oceans they are one of the best health indicators for people. If salmon aren’t doing well, then we should think about whether people should be drinking or using that same water. The salmon population in the area around Puget Sound is not doing well.”

We talked a bit more about pesticides in general and Dr. White summed up the essence of the entire indoor-outdoor farming and pesticides debate succinctly.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”

If you extrapolate that thought, the same applies to agriculture. Greenhouse farming, while subject to some problems not endemic to outdoor farming, quite simply puts a lot fewer chemicals in the air we breathe, the water we drink and the food we eat.

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
The antimicrobial flooring options available from some manufacturers offer further hygiene support in highly sensitive facilities
Today’s industrial resinous floor coatings from reputable suppliers are very low to zero V.O.C. and compliant with EPA and other environmental regulations

Resinous coating systems provide ideal value to informed growers who require durable, reliable and long-lasting high performance flooring for their facilities.

Support from the Ground Up

From incredible medical advances to high tensile fiber in construction materials, the expanding cannabis industry is bringing exciting opportunities to many areas of the economy. As more and more growers enter the market, so increases the pressure to compete.

By choosing light reflective, seamless and moisture tolerant resinous flooring that meets regulatory guidelines for grow rooms, managers can help reduce their overhead costs on multiple fronts — and get a jump on the competition.
