The Stress of a Grower

By Carl Silverberg
1 Comment

Tell me that you can’t relate to this story.

You’re sitting down to dinner at a restaurant about ten minutes from where you work, finally relaxing after a tough day. You’ve set your environmental alerts on your plants; you have that peace of mind that the technology promised and you know that if anything goes wrong you’ll get notified immediately. As you’re looking at the menu, you receive an alert telling you that the temperature in one of your 2,000 square foot grow rooms has gone out of the safe range. Your mind starts to race, “It’s week seven, I’ve got 500 plants one week away from harvest, that’s 200 pounds of cannabis worth about $150,000-$200,000. Oh my God, what am I going to do?”

You’re doing all this at the dinner table and even though you’re not in a state of panic, you are extremely concerned. You need to figure out what’s going on. You check the graphing and see that over the past hour your humidity dropped and your temperature is gradually going up. Within the past ten minutes, the temperature has gone to 90 degrees. Your numbers tell you that the temperature in the room with $200,000 of cannabis is going up about five degrees every three minutes.

Monitoring a large grow room can be a stressful task.

“I see this trend and can’t figure it out,” the grower relates. “Normally, the HVAC kicks on and I’d begin to see a downward trend on the graphs. I pre-set my trigger for 90 degrees. But, I’m not seeing that. What I AM seeing is the temperature gradually and consistently getting warmer without the bounce-back that I would expect once the HVAC trigger was hit. All I know is I better find out what’s causing all this and I better find out fast or my entire crop is gone.”

You go through the rest of the checklist from LUNA and you see that the lights are still on. Now, you’re starting to sweat because if the temperature in that room hits 130 and stays there for more than twenty minutes, you’re losing your entire crop. You have to walk in your boss’s office the next day and explain why, after all the time and money you put in over the past seven weeks, not only is all that money gone but so is the $200,000 he is counting on to pay salaries, expenses, and bank loans.

This is something you’ve been working on for seven straight weeks and if you don’t make the right decision, really quickly, when that room hits 130 degrees here’s what happens.

“My equipment starts to fail,” our grower continues. “The crop literally burns as the oils dry up and the crop is worthless. At 130 degrees, my grow lights essentially start to melt. All you can think of is that temperature going up five degrees every three minutes and you’re ten minutes from your facility. I need to leave that restaurant right now, immediately, because even if I get there in ten minutes the temperature is going to be almost 120 degrees while I’ve been sitting here trying to figure out what’s wrong.”

You run out to your car and you speed back to the facility. The grow room is now 125 degrees, you have maybe three or four minutes left to figure things out before you flush $200,000 down the drain. The first thing you do is turn off the grow lights because that’s your primary source of heat. Then, you check your HVAC panel and you realize it malfunctioned and shorted out. There’s the problem.

The real toll is the human cost. Once this happens, no grower ever wants to leave and go home or even go to dinner. It’s a horrible toll. It’s the hidden cost we don’t talk about. The grower opens up with his own personal experience.“This system allows the grower to step back and still feel confident because you’re not leaving your facility to another person,” 

“You think about the burden on the person that you bring in to replace you while you’re out of town and then you think about the burden on you if something goes wrong again. And you decide, it’s not worth it. The anxiety, the fear that it will happen again, it’s not worth it. So, you don’t go. I didn’t even see my sister’s new baby for eight months.”

Your desire to see your family, your desire to have a normal life; all of that goes out the window because of your desire to be successful in your job. It outweighs everything.

This is every grower. It’s why many farmers never leave their property. It just becomes a normal way of living. You just repeat it so much that you don’t even think about it. Why go on vacation if your stress level is higher than it is if you’re home. You’re constantly worried about your farm or your facility. The only way to escape it is to not go away at all.

“This system allows the grower to step back and still feel confident because you’re not leaving your facility to another person,” he tells us. “You don’t realize how stressful a lifestyle you live is until you step back and look at it. Or, if you have an alert system that allows you to pull back. That’s when you realize how difficult your life is. Otherwise, it just seems normal.”

As AI technology expands its footprint into agriculture, there will be more tools to help mediate situations like this; more tools to give you a more normal life. It’s one of the reasons we got into the business in the first place.

Fungal Monitoring: An Upstream Approach to Testing Requirements

By Bernie Lorenz, PhD
No Comments

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.

Photo credit: Steep Hill- a petri dish of mold growth from tested cannabis

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.

Best practices include quality control protocols while 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.The 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.”

From CannTrust To Canopy: Is There A Connection To Current Cannabis Scandals?

By Marguerite Arnold
No Comments
Canopy_Growth_Corporation_logo

As Europe swooned under record-breaking heat this summer, the cannabis industry also found itself in a rather existential hot seat.

The complete meltdown at CannTrust has yet to reach a conclusion. Yes, a few  jobs have been lost. However, a greater question is in the room as criminal investigatory and financial regulatory agencies on both sides of the US-Canada border (plus in Europe) are getting involved.

As events have shown, there is a great, big, green elephant in the room that is now commanding attention. Beyond CannTrust, how widespread were these problematic practices? And who so far has watched, participated, if not profited, and so far, said nothing?

Who, What, Where?

The first name in the room? Canopy Growth.Canopy_Growth_Corporation_logo

Why the immediate association? Bruce Linton, according to news reports, was fired as CEO by his board the same day, July 3, 2019, that CannTrust received its first cease and desist notice from Health Canada.

Further, there is a remarkable similarity in not only problematic practices, but timing between the two companies. This may also indicate that Canopy’s board believed that Linton’s behaviour was uncomfortably close to executive misdeeds at CannTrust. Not to mention, this was not the first scandal that Linton had been anywhere close to around acquisition time. See the Mettrum pesticide debacle, that also broke right around the time Canopy purchased the company in late 2016 as well as the purchase of MedCann GmbH in Germany.

Reorg also appears to be underway in Europe as well. As of August, Paul Steckler has been brought in as “Managing Director Europe” and is now based in Frankfurt. Given the company’s history of “co-ceo’ing” Linton out the door, is more change to come?

What Went Down At Canopy?

Last year, Canopy announced its listing on the NYSE in May. To put this in context, this was two months after the first German cultivation bid went down to legal challenge. By August 15, 2018 with a new bid in the offing, the company had closed the second of its multi-billion dollar investments from Constellation.

Yet by late October, after Bruce Linton skipped a public markets conference in Frankfurt where many of the leading Canadian cannabis company execs showed up to lobby Jens Spahn (the health minister of Germany) about the bid if not matters relating to the Deutsche Börse, there were two ugly rumours afoot.

Video showing dead plants at Canopy’s BC facility surfaced. Worse, according to the chatter online at least, this was the second “crop failure” at the facility in British Columbia. Even more apparently damning? This all occurred during the same  time period that the second round of lawsuits against the reconstituted German cultivation bid surfaced.

Canopy in turn issued a statement that this destruction was not caused by company incompetence but rather a delay in licensing procedures from Health Canada. Despite lingering questions of course, about why a company would even start cultivation in an unlicensed space, not once but apparently twice.  And further, what was the real impact of the destruction on the company’s bottom line?

Seen within the context of other events, it certainly poses an interesting question, particularly, in hindsight.

Canopy, which made the finals in the first German cultivation bid, was dropped in the second round – and further, apparently right as the news hit about the BC facility. Further, no matter the real reason behind the same, Canopy clearly had an issue with accounting for crops right as Canadian recreational reform was coming online and right as the second German cultivation bid was delayed by further legal action last fall.

Has Nobody Seen This Coming?

In this case, the answer is that many people have seen the writing on the wall for some time. At least in Germany, the response in general has been caution. To put this in true international perspective, these events occurred against a backdrop of the first increase in product over the border with Holland via a first-of-its kind agreement between the German health ministry and Dutch authorities. Followed just before the CannTrust scandal hit, with the announcement that the amount would be raised a second time.

German health authorities, at least, seem doubtful that Canadian companies can provide enough regulated product. Even by import. The Deutsche Börse has put the entire public Canadian and American cannabis sector under special watch since last summer.

Common Territories

By the turn of 2019, Canopy had announced its expansion into the UK (after entering the Danish market itself early last year) and New York state.

And of course by April, the company unveiled plans to buy Acreage in the U.S.

Yet less than two weeks later, Canopy announced not new cultivation facilities in Europe, but plans to buy Bionorica, the established German manufacturer of dronabinol – the widely despised (at least by those who have only this option) synthetic that is in fact, prescribed to two thirds of Germany’s roughly 50,000 cannabis patients.

By August 2019, right after the Canopy Acreage deal was approved by shareholders, Canopy announced it had lost just over $1 billion in the last three months.

Or, to put this in perspective, 20% of the total investment from Constellation about one year ago.

What Happened At CannTrust And How Do Events Line Up?

The current scandal is not the first at CannTrust either. In November 2017, CannTrust was warned by Health Canada for changing its process for creating cannabis oil without submitting the required paperwork. By March of last year however, the company was able to successfully list on the Toronto stock exchange.

Peter Aceto arrived at CannTrust as the new CEO on October 1 last year along with new board member John Kaken at the end of the month. Several days later the company also announced that it too, like other major cannabis companies including Canopy, was talking to “beverage companies.” It was around this time that illegal growing at CannTrust apparently commenced. Six weeks later, the company announces its intent to also list on the NYSE. Two days later, both the CEO and chair of the board were notified of the grow and chose not to stop it.

Apparently, their decision was even unchanged after the video and resulting online outrage about the same over the destroyed crops at the Canopy facility in BC surfaced online.

On May 10, just over a week after the Bioronica purchase in Germany, the first inklings of a scandal began to hit CannTrust in Canada. A whisteblower inside the company quit after sending a mass email to all employees about his concerns. Four days later, the company announced the successful completion of their next round of financing, and further that they had raised 25.5 million more than they hoped.

Six weeks later, on June 14, Health Canada received its warning about discrepancies at CannTrust. The question is, why did it take so long?

Where Does This Get Interesting?

The strange thing about the comparisons between CannTrust and Canopy, beyond similarities of specific events and failings, is of course their timing. That also seems to have been apparent at least to board members at Canopy – if not a cause for alarm amongst shareholders themselves. One week after Health Canada received its complaint about CannTrust, shareholders voted to approve the Canopy-Acreage merger, on June 21.

Yet eight days after that, as Health Canada issued an order to cease distribution to CannTrust, the Canopy board fired Bruce Linton.

One week after that, the Danish recipient of CannTrust’s product, also announced that they were halting distribution in Europe. By the end of August, Danish authorities were raising alarms about yet another problem – namely that they do not trust CannTrust’s assurances about delivery of pesticide-free product.

Is this coincidence or something else?

If like Danish authorities did in late August 2019, calling for a systematic overhaul of their own budding cannabis ecosystem (where both Canadian companies operate), the patterns and similarities here may prove more than that. Sit tight for at least a fall of more questions, if not investigations.

Beyond one giant cannabis conspiracy theory, in other words, the problems, behaviour and response of top executives at some of the largest companies in the business appear to be generating widespread calls – from not only regulators, but from whistle blowers and management from within the industry itself – for some serious, regulatory and even internal company overhauls. Internationally.

And further on a fairly existential basis.


EDITOR’S NOTE: CIJ reached out to Canopy Growth’s European HQ for comment by email. None was returned.

Correction: This article has been updated to show that the Danish recipient of Canntrust’s product announced they were halting distribution one week after Bruce Linton’s firing, not one day. 

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

By Susan Preston, T.J. Frost
No Comments

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.

When You Don’t Know What You Don’t Know: Debunking Cannabis Insurance Myths

By , T.J. Frost

For all of today’s growing acceptance and legitimacy with cannabis, the reality is that today’s operators – whether growers/producers or dispensary operators – still face risks in running their businesses. If, in the old days, a customer got deathly ill from cannabis contaminated with something from somewhere during the distribution chain, oh, well. But now that there’s a legal system of checks and balances; there’s recourse when issues arise.

The problem is that the business is so new that most people don’t know what they don’t know about mitigating those risks. And that, unfortunately, extends to many in the insurance business who need to be doing a better job helping put the right protections in place.

One grower bemoaned to me at a cannabis trade show, “I sure wish I could insure my crops.” What? “You can,” I told him. His old-school ag broker didn’t know any better and didn’t do him any favors with his ignorance. But it brought home the point: We have to start treating cannabis like the real business it is.

Reviewing the existing insurance policies of today’s cannabis businesses uncovers some serious gaps in coverage that could be financially crippling if not downright dangerous should a claim be triggered. Retail dispensaries, for example, are high-cash businesses, making banking and trusted employees a must-have.Today’s cannabis businesses need to understand there will be risks but they are a lot more manageable than in the old days. 

And a close eye must be cast to lease agreements for hidden exposures, too. We know a Washington state grower that had no property insurance on its large, leased indoor growing facility. The company’s lease made its owners, not their landlord, responsible for any required building improvements. It was one of a variety of serious exposures that had to be fixed.

Today’s cannabis businesses need to understand there will be risks but they are a lot more manageable than in the old days. Rather than find themselves under-insured, they can start by learning what they probably have wrong about insurance. Dispelling three of the most common myths is a good place to start.

Myth #1: Nobody will insure a cannabis business.

Not remotely true. You can and should get coverage. Think property and casualty, product liability, EPLI and directors and officers, employee benefits and workers comp. Additionally, you should be educated on what crop coverage does and doesn’t cover. Depending on your business’ role in production and distribution, you might also consider cargo, stock throughput, auto, as noted, crime and cyber coverage. It pays to protect yourself.

Myth #2: If my business isn’t doing edibles, I don’t have to worry about product liability insurance.

The reality is that product liability may be the biggest risk the cannabis industry faces, at every level on the supply chain. There’s a liability “trickle down” effect that starts with production and distribution and sales and goes down to labeling and even how the product is branded. Especially when a product is an edible, inhalable or ingestible with many people behind it, the contractual risk transfer of product liability is an important consideration. That means the liability is pushed to all those who play any role in the supply chain, whether as a producer or a retailer or an extractor. And all your vendors must show their certificates of insurance and adequate coverage amounts. Don’t make the mistake of being so excited about this new product that you don’t check out the vendors you partner with for this protection.

Myth #3: Any loss at my operation will be covered by my landlord’s policy.

As the example I cited early illustrated, that’s unlikely. Moreover, your loss might even cause your landlord’s insurance to be nullified for having rented to a cannabis business. It’s another reason to examine your lease agreement very carefully. You want to comply with your landlord’s requirements. But you also need to be aware of any potential liabilities that may or may not be covered. Incidentally, even if your landlord’s policy offers you some protection, your interests are going to be best served through a separate, stand-alone policy for overall coverage.

These are interesting times for the burgeoning legal cannabis business. Getting smart – fast – about the risks and how to manage them will be important as the industry grows into its potential.

Flooring Tips for Cannabis Growing Facilities

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:

  1. 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
  2. Be impervious and non-porous, providing a surface that can isolate toxic materials on the surface for proper clean-up where needed
  3. Enable correction or improvement of the floor slope for proper drainage, with no low spots to help avoid puddling
  4. Be installed with integral floor-to-wall cove options for easier wash-down and sanitizing
  5. Have the strength and thermal shock resistance, plus the tenacious bond, to undergo steam-cleaning and/or hot power washing, where needed
  6. Enable seamless, continuous surface installation over concrete curbs and containment areas
  7. Offer antimicrobial options for highly sensitive locations
  8. Demonstrate high compressive strength and impact resistance for durability under heavy loads
  1. Display excellent abrasion resistance, allowing the system to perform under grueling daily wear-and-tear
  2. Present customizable slip-resistance options that can be balanced with easy clean-ability
  3. Facilitate the use of floor safety markings, such as color-coded traffic and work area designations
  1. Be formulated with low odor, low-VOC chemistries that meet all EPA and similar regulations
  2. Be able to contribute LEED Green Building Credits, where desired
  3. 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
  4. Withstand and perform in continually damp grow room conditions, without degrading
  5. Be compliant with FDA, USDA, EPA, ADA, OSHA, as well as local regulations and/or guidelines
  6. Include MVT mitigating solutions where Moisture Vapor Transmission site issues are present
  7. Provide waterproofing underlayment options for multi-story facilities
  8. 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.

Climate Change Drives Cannabis Indoors

By Carl Silverberg

This is not a discussion of climate change, it’s a discussion of the impact of weather on the agriculture industry. The question for the cannabis & hemp industry, and basically the entire specialty crop industry, is what will be the impact? According to the U.S. National Climate Assessment, “Climate disruptions to agriculture have been increasing and are projected to become more severe over this century.” I’m sure that’s not much of a shock to anyone who owns a farm, orchard or greenhouse.

Every national newspaper for the past two weeks has published at least one article a day about the flooding in the Midwest, while industry newsletters and blogs have contained more in-depth stories. The question is, what can agriculture professionals do to mitigate these problems?

Relying on state and national legislators, especially heading into a presidential election year is likely to be frustrating and unrewarding. Governments are excellent at reacting to disasters and not so good at preventing them. In short, if we depend on government to take the lead it’s going to be a long wait.Instead, many farmers are looking at the future costs of outdoor farming and concluding that it’s simply cheaper, more efficient and manageable to farm indoors.

Instead, many farmers are looking at the future costs of outdoor farming and concluding that it’s simply cheaper, more efficient and manageable to farm indoors. Gone are the days when people grew hemp and cannabis indoors in an effort to hide from the police. Pineapple Express was a funny movie but not realistic in today’s environment.

Today’s hemp and cannabis growers are every bit as tech savvy as any other consumer-oriented business and one could argue that given the age of their customers (Statista puts usage by 18-49-year-olds at 40%), distributors must be even more tech savvy to compete effectively. Some estimates put the current split of cultivation at about one-third indoors/two-thirds outdoors. To date, the indoor focus has been on efficiency, quality and basically waiting for regulators to allow shipping across state lines.

A major driver in the indoors/outdoors equation is that as the weather becomes more unfriendly and unpredictable, VC’s are factoring climate disruption into their financial projections. When corn prices drop because of export tariffs, politicians lift the ban on using Ethanol during the summer months. It’s going to be a while before we see vehicles running on a combination of gasoline and CBD.

Leaving aside the case that can be made for efficiency, quality control and tracking of crops, climate change alone is going to force many growers to reassess whether they want to move indoors. And, it’s certainly going to weigh heavily in the plans of growers who are about to launch a cannabis or hemp business. Recently, one investment banker put it to me this way: greenhouses are the ultimate hedge against the weather.

Why the Central Chiller Isn’t So Central to Grow Room HVAC

By Geoff Brown

There’s a better way to design HVAC for cannabis grow rooms, and it may seem a little odd at first.

Central chillers are a tried-and-true solution for projects requiring large refrigeration capacity. They’re found in college campuses, hospitals, office buildings and other big facilities.

While central chillers are a good default for most large-scale applications, they fall short in this industry. Grow rooms, with their need for tight, variable conditions and scalable, redundant infrastructure, have HVAC requirements that the central chiller model simply can’t deliver on.

Let’s unpack the shortcomings with the central chiller in this niche and explore some possible solutions.

What’s Wrong With Chillers?

Building a scalable HVAC system is essential for the cannabis industry as it continues to ramp up production in the U.S. and Canada.

Many growers are building their large facilities in phases. In Canada, this is common because growers must have two harvests before they can receive a production permit, so they build just one phase to satisfy this requirement and then build out the facility after the government’s approval.

This strategy of building out is less feasible with a central chiller.

solsticegrowop_feb
Indoor cultivator facilities use high powered lights that give off heat, requiring an efficient air cooling system.

A chiller and its supporting infrastructure are impractical to expand, which means it and the rest of the facility needs to be built to full size for day one, even though the facility will be in partial occupancy for a long time. This results in high upfront capital costs.

If the facility needs to expand later down the road, to meet market demand for example, that will be difficult because, as mentioned, it’s expensive to add capacity to a central chiller.

Additionally, the chiller creates a central point of failure for the facility. When it goes down, crops in every room are at risk of potentially devastating loss. Grow rooms are unusual because of their requirement for strict conditions and even a slight change could have big impact on the crop. Losing control due to mechanical failure could spell disaster.

One Southern Ontario cannabis grower met with some of these issues after constructing their facility, which uses a central chiller for cooling and dehumidification. The chiller was built for full size, but the results were disappointing as early as phase one of cultivation. While sensible demands in the space are being easily met, humidity levels are out of control – flowering rooms are up to 75% RH.

Humidity is one of the most important control aspects to growers. Without a handle on it, growers risk losing their entire crop either because there’s not enough and the plants dry out, or there’s too much and the plants get mold disease. This facility has fortunately not yet reported serious crop issues but is mindful of the potential impact on harvest quality.

By going unitary, capital costs scale on a linear basis.If tight control over humidity is what you need, then a chilled water system needs very careful consideration. That’s because typical chiller system designs get the coils cold enough to lower the air temperature, but not cold enough to condense water out of the air as effectively as a properly designed dehumidifier coil.

A chilled water system capable of achieving the coil temperatures needed for adequate dehumidification in a typical flower room will also require full-time reheat to ensure that air delivered to the plants isn’t shockingly cold — either stunting their growth or killing them altogether. This reheat source adds complexity, cost and inefficiency which does not serve growers well, many of whom are under pressure from both utilities and their management to minimize their energy usage.

How Do Unitary Systems Solve These Problems?

Compared to central chillers, a unitary setup is more agile.

A facility can commence with the minimum capacity it needs for start-up and then add more units in the future as required. They’re usually cheaper to install than a central system and offer several reliability and efficiency benefits as well.

The real business advantage to this approach is to open up the grower’s cash flow by spreading out their costs over time, rather than a large, immediate cost to construct the entire facility and chiller for day one. By going unitary, capital costs scale on a linear basis.

Growers can have more control over their crop by installing multiple units to provide varying conditions, room-by-room, instead of a single system that can only provide one condition.

For example, flowering rooms that each have different strains of crop may require different conditions – so they can be served by their own unit to provide variability. Or, rooms that need uniform conditions could just be served by one common unit. The flexibility that growers can enjoy with this approach is nearly unlimited.

Some growers have opted for multiple units installed for the same room, which maximizes redundancy in case one unit fails.

A cannabis facility in the Montreal area went this direction when building their HVAC system. Rather than build everything in one shot, this facility selected a unitary design that had flowering rooms served independently by a series of units, while vegetation rooms shared one. The units were sized to provide more capacity than currently required in each room, which allows the grower to add more plants and lighting in the future if they choose.

This facility expects to build more grow rooms in a future phase, so it was important to have an intelligent system that could accommodate that by being easy to add capacity to. This is accomplished by simply adding more units.Multiple, small systems also have a better return-on-investment.

The grower, after making a significant investment in this facility, was also averse to the risk of losing crop due to mechanical failure, which is why they were happy to go with a system of independent grow room control.

Multiple, small systems also have a better return-on-investment. Not only are they easier to maintain (parts are easier to switch out and downtime for maintenance is minimal) but they can actually be more efficient than a large, central system.

Some units include heat recovery, which recycles the heat created by the dehumidification process to efficiently reheat the unit’s cold discharge air and keep the space temperature consistent, without needing expensive supplementary heaters. There’s also economizer cooling, which can be used to reduce or even eliminate compressor usage during winter by running the unit on dry outside air only.

Demand for cannabis continues to increase and many growers are looking to expand their businesses by adding new facilities or augmenting existing ones. Faced with the limitations of the traditional chiller system, like the lack of flexibility, scalability and redundancy, they’re looking for an intelligent alternative and the unitary approach is earning their trust. It’s expected this option will soon become the leading one across North America.

Farmako Inks Deal To Import 50 Tonnes of Polish Cannabis Into Germany

By Marguerite Arnold

The ex-im cannabis map of Europe has been promising to get interesting for some time. And in March, it’s long promised potential just bloomed a little more as Frankfurt-based Farmako announced a first-of-its kind import deal of 50 tonnes of medical cannabis (and from Poland no less) over the next four years.

Farmako was just founded in September 2018. They began distribution to German pharmacies this month. They also have an office in London and cross-European aspirations.

While Farmako is the first to announce such a unique cross-border production and distribution agreement, however, they are far from the only ones planning the same. In fact at least Tilray is expected to announce that their newly-minted Portuguese crop is being processed into oil bound for German pharmacies any day now. It is also not unrealistic to expect that (at least) Canopy Growth, of the big Canadian producers at least, will soon announce the same situation for their crops in countries across the continent, starting with Spain.

Outside Germany of course, this kind of entrepreneurial endeavour is already underway. In the UK, a new import group just announced the first bulk shipment of Dutch medical cannabis into the country, distributed directly to over 1,000 pharmacies nationwide.

There still are a couple of jaw-dropping things to consider about this new German development. Namely, that the amount of just this deal over the next four years between two (relatively new, non-Canadian) companies is approximately five times the amount currently called for in the still pending domestic cultivation bid in Germany.

The second, of course, is that the Polish company on the other side of the border and this ex-im deal, PharmaCann Polska, is a uniquely positioned conglomeration of individuals with apparently Canadian and Israeli market experience. This means that they are already positioned to access the biggest two production markets in the world and are certain to be looking to exploit other Eastern European connections (at minimum). If not ones further afield than that.

One thing is absolutely certain far beyond the particulars of this one deal. The current import limitations from Canada and the Netherlands into the German market appear to be a thing of the past. And the cross-border trade for medical cannabis is now clearly entering a new phase.

Implications

Farmako clearly intends to go after the existing Canadians in the market on price, which means both Canopy Growth and Tilray. But it also means Wayland, at this point is the largest domestic certified producer (albeit with Canadian roots and partners) and an entire licensed facility in eastern Germany ready to go. That is not an insignificant threat and sets up another looming question: Which will actually be cheaper in the long run? Domestically grown German cannabis, or that imported from adjacent countries with lower paying labor markets?

This announcement also means that the “cannabis shortage” in the country is officially over as of this spring. And that won’t just come from Farmako but others already in the market and those angling now to get in via other creative means.

Regardless, what that will do to overall sales, patient numbers and overall speed is another matter.

Other Looming Problems

There are two big issues that this development does not solve of course. The first is the ability of patients to find doctors willing to prescribe the drug, and further to make sure they spend the time filling out the paperwork and negotiating with the patient’s insurer, to make sure that patients can actually get it. Starting with affording medical cannabis in the first place. Most patients on what is known as “statutory” health insurance (90% of the country) cannot afford the out of pocket cost at pharmacies without insurance approvals. Once they get them, they pay up to $12 for a month’s supply (in the case of flower, about an ounce).

The second issue is that it is currently unclear, mostly due to the lack of granularity provided by the country’s statutory health insurers, what is actually being prescribed for which kind of condition and to whom. Earlier this month, new information was made available about the overall growth of coverage of medical cannabis in Germany. While the total spending, and rough breakdown of flowers vs. product was provided, it is unclear beyond that, where this is going. There were also apparently just over 46,000 patients in Germany as of December 2018. And this is a growth trend that while clearly on an upward trajectory for the last three quarters is slow and steady as she goes. The sudden uptick in the market seen in the second quarter of last year appears to be an anomaly.

Further, understanding market price points is also hard. Flos and prepared pharmaceuticals such as Sativex are highly expensive right now. In the case of the Canadian firms, their medical exports are being sold at about twice the price of their domestic recreational sales points. Look for this to change dramatically as real competition heats up across Europe (and from more distributors than just this Frankfurt upstart).

What the news in other words about Farmako really signifies is that the price barriers in the medical market are about to come down at the point of sale- and hopefully in the short term, patients will not have to rely on the approval of their insurance companies to be able to access the drug because they will be able to afford it themselves. No matter what happens with the bid. Although this too will also serve to lower prices.

The great medical normalization race for medical cannabis in Europe is now officially “on.” And that is good news not only for patients, but of course, the industry.
