Fungal Monitoring: An Upstream Approach to Testing Requirements

By Bernie Lorenz, PhD

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.”

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.

According to a press release yesterday, Illumitex, an industry-leading LED lighting manufacturer and digital horticulture company, announced the release of their newest lighting technology, the Illumitex HarvestEdge Extra Output (XO) LED Horticultural Fixture. This light fixture is the latest advancement of their LED technology, which they claim can help growers maximize their yield considerably.

The HarvestEdge Extra Output (XO) LED Horticultural Fixture

The fixture comes with a 0-10 dimming capability and proven Wet Rating, meaning it is designed and proven to operate normally in a high-humidity environment. Debuted during the NCIA Seed to Sale Show in Boston, MA on February 12^th, the company says the XO LED is the first true 1:1 replacement for high pressure sodium (HPS) lights, consuming about 36% less energy.

We caught up with a few members of the Illumitex team at the conference to find out more about the technology and its applications. According to John Spencer, CCO/EVP of Sales & Marketing at Illumitex, their technology has been used by hundreds of grow operations over the past 8 years. “This light was designed with a higher light output for greenhouses, particularly in Canada where the mounting heights are upwards of 7 meters,” says Spencer. “We are minimizing shadowing in the greenhouse, giving growers the opportunity to supplement their sunlight appropriately.” He says they are specifically designed with commercial scale use in mind.

According to Yan Ren-Butcher, Ph.D., Director of Horticulture Science at Illumitex, the light has the highest efficacy on the market right now. “We designed the specific wavelengths and best red, blue and green ratios optimal for photosynthesis,” says Ren-Butcher. “This product launch is based on years and years of experience in horticultural applications, our knowledge in the field of cannabis cultivation and the latest in LED technology, with the highest efficacy in the industry to date.”

Heavy Metals Testing: Methods, Strategies & Sampling

By Charles Deibel

3 Comments

Editor’s Note: The following is based on research and studies performed in their Santa Cruz Lab, with contributions from Mikhail Gadomski, Lab Manager, Ryan Maus Technical Services Analyst, Laurie Post, Director of Food Safety & Compliance, and Charles Deibel, President Deibel Cannabis Labs.

Heavy metals are common environmental contaminants resulting from human industrial activities such as mining operations, industrial waste, automotive emissions, coal fired power plants and farm/house hold water run-off. They affect the water and soil, and become concentrated in plants, animals, pesticides and the sediments used to make fertilizers. They can also be present in low quality glass or plastic packaging materials that can leach into the final cannabis product upon contact. The inputs used by cultivators that can be contaminated with heavy metals include fertilizers, growing media, air, water and even the clone/plant itself.

The four heavy metals tested in the cannabis industry are lead, arsenic, mercury and cadmium. The California Bureau of Cannabis Control (BCC) mandates heavy metals testing for all three categories of cannabis products (inhalable cannabis, inhalable cannabis products and other cannabis and cannabis products) starting December 31, 2018. On an ongoing basis, we recommend cultivators test for the regulated heavy metals in R&D samples any time there are changes in a growing process including changes to growing media, cannabis strains, a water system or source, packaging materials and fertilizers or pesticides. Cultivators should test the soil, nutrient medium, water and any new clones or plants for heavy metals. Pre-qualifying a new packaging material supplier or a water source prior to use is a proactive approach that could bypass issues with finished product.

Testing Strategies

The best approach to heavy metal detection is the use of an instrument called an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). There are many other instruments that can test for heavy metals, but in order to achieve the very low detection limits imposed by most states including California, the detector must be the ICP-MS. Prior to detection using ICP-MS, cannabis and cannabis related products go through a sample preparation stage consisting of some form of digestion to completely break down the complex matrix and extract the heavy metals for analysis. This two-step process is relatively fast and can be done in a single day, however, the instruments used to perform the digestion are usually the limiting step as the digesters run in a batch of 8-16 samples over a 2-hour period.

Only trace amounts of heavy metals are allowed by California’s BCC in cannabis and cannabis products. A highly sensitive detection system finds these trace amounts and also allows troubleshooting when a product is found to be out of specification.

For example, during the course of testing, we have seen lead levels exceed the BCC’s allowable limit of 0.5 ppm in resin from plastic vape cartridges. An investigation determined that the plastic used to make the vape cartridge was the source of the excessive lead levels. Even if a concentrate passes the limits at the time of sampling, the concern is that over time, the lead leached from the plastic into the resin, increasing the concentration of heavy metals to unsafe levels.

Getting a Representative Sample

The ability to detect trace levels of heavy metals is based on the sample size and how well the sample represents the entire batch. The current California recommended amount of sample is 1 gram of product per batch. Batch sizes can vary but cannot be larger than 50 pounds of flower. There is no upper limit to the batch sizes for other inhalable cannabis products (Category II).

It is entirely likely that two different 1 gram samples of flower can have two different results for heavy metals because of how small a sample is collected compared to an entire batch. In addition, has the entire plant evenly collected and concentrated the heavy metals into every square inch of it’s leaves? No, probably not. In fact, preliminary research in leafy greens shows that heavy metals are not evenly distributed in a plant. Results from soil testing can also be inconsistent due to clumping or granularity. Heavy metals are not equally distributed within a lot of soil and the one small sample that is taken may not represent the entire batch. That is why it is imperative to take a “random” sample by collecting several smaller samples from different areas of the entire batch, combining them, and taking a 1 g sample from this composite for analysis.

Seven Steps To Avoid the Green Rush Blues: Investigate Water Supplies Before Planting Cannabis

By Amy M. Steinfeld

2 Comments

A clean, reliable water supply lies at the heart of every successful cannabis farm. It’s no surprise that the stakes for finding land with ideal growing conditions, including adequate water, are high. But new buyers (and lessees) caught up in the green rush often gloss over water rights or are unaware of California’s byzantine rules governing the irrigation of cannabis.

Water rights are complex. Water regulations applicable to cannabis cultivation are even more complex. And our new climate reality convolutes things further. Longer droughts, more volatile weather, political uncertainties, increased groundwater regulation and water quality concerns are exacerbating tensions over local and statewide water supplies. In many areas of California, landowners can no longer rely on local water districts to meet their needs.

A robust investigation of the property must consider water supplies. Because a property’s water supply is dependent on water rights, local ordinances, state regulations, politics and hydrology, it’s important to consult a water lawyer (and in some instances a hydrologist) before closing. A bit of foresight can prevent a grower from being left high and dry.

The following checklist provides a roadmap to conduct water rights’ due diligence. While many of these details are California-specific, this type of due diligence applies throughout the West.

Step 1: Identify Available Water Supplies and Consider Potential Limitations On Irrigation, Including Potential Future Changes

Conduct a site visit to identify existing water infrastructure, natural water features and existing or potential water service options. Next, determine if the property is served by a public water supplier. If that’s the case, the California State Water Resources Control Board (“State Water Board”) does not require any specific documentation to irrigate cannabis, but the water supply must be disclosed in the CalCannabis license application.

Groundwater is generally the best supply for cannabis, but the era of unregulated groundwater pumping is over. Many groundwater basins in California are now governed by the Sustainable Groundwater Management Act (“SGMA”), which requires water agencies to halt overdraft and restore balanced levels of groundwater pumping from certain basins. As a result, SGMA may result in future pumping cutbacks or pumping assessments. It’s imperative to identify the local groundwater basin via the Department of Water Resources’ Bulletin 118, and determine whether the groundwater basin is adjudicated or governed by a groundwater sustainability agency. Growers should also test the local water supply’s pH and salt levels because cannabis plants are finicky and water treatment can be cost prohibitive. If a new well is needed, growers should consult with their local county before drilling a new well. In some areas, moratoriums and restrictions on drilling new wells are on the rise.

As a rule of thumb, cannabis cultivators should avoid using surface water to irrigate cannabis. Surface diversions are subject to the California Department of Fish and Wildlife’s permitting authority. And under the interim State Water Board Cannabis Policy, commercial cannabis cultivators cannot divert anysurface water during the dry season (April 1 through Oct. 31), even if they have a riparian right that can be used to irrigate other crops. During the dry season, cultivators may only irrigate using water that has been stored off-stream. And even during the wet season, cannabis cultivators must comply with instream flow requirements and check in with the state daily to ensure adequate water supplies are available. Cannabis cultivators are also required to install measuring devices and track surface water diversions daily. And buyer beware, a groundwater well that extracts water from a subterranean stream may be considered a surface-water diversion. So be especially cautious if the well is located close to a creek or river.Develop a water use plan to optimize water efficiency

Step 2: Identify Water Supplies Used On the Property, Including the Basis of Right, and Quantify Historical Use

Review information on historic and existing water use. This may include past water bills and assessments. If there is a well on the property, the seller or lessor may have metering data, electrical records and crop data that can establish historic groundwater use. Cultivators must submit a well log to CalCannabis as part of the cannabis cultivation application. If surface water is available, the purchaser should review the State Water Board eWRIMs database for water rights permits, licenses, stock pond registrations and certificates, decisions and orders. The purchaser should also identify surface water diversion structures and review annual filings to determine compliance with all terms and conditions of the water right. Lastly, the purchaser should request all documents and contracts pertaining to water rights.

Realistically estimate water demand for irrigation and other on-site purposes.Step 3: Confirm Ownership of Right and Assess Any Limitations On Water Right

Determine whether the right has been abandoned, lost to prescription or forfeited. Evaluate the seniority of the water right, availability of the right, adequacy of place of use, purpose of use (must include irrigation), season of use, and quantity of any permitted or licensed post-1914 right. Determine whether historical diversions pursuant to an appropriative right support the full amount of the claimed right, and whether any changes to the water right are needed to support the proposed new use. Cultivators in California who plan to utilize surface water also need to file for a “Cannabis Small Irrigation Use Registration” to store water during the wet season for use during the dry season.

Step 4: Reconcile Water Demand With Available Supply

Realistically estimate water demand for irrigation and other on-site purposes. Develop a water use plan to optimize water efficiency (drip irrigation, rainwater harvesting, water monitoring, hoop structures) regardless of supply sufficiency. Many counties, such as Santa Barbara County, require that cannabis growers meet certain irrigation efficiency standards. Determine whether available supplies can meet all proposed demands, including plans for full buildout. If not, consider whether additional supplies are available for use on the property.

Step 5: Determine Water Supply Compliance Obligations

The rights associated with water supplies are defined by their source, the time frame during which supplies can be taken, the quantity of water to which the right attaches, and any limitations on the purpose of use of the water supply. There may also be reporting requirements associated with taking and using the supply—these can include requirements to report the quantity of water used as well as information regarding the end use of the water. Failure to timely report can have serious consequences. Cannabis cultivators are also subject to additional water quality regulations and restrictions, including waste discharge requirements pursuant to the State Water Board’s Cannabis General Order.

Step 6: Negotiate Deal and Draft Conveyance Documents

After obtaining an understanding of the water supply associated with the property, the property conveyance documents may be drafted to incorporate the transfer of rights associated with the property’s water supplies. These may include the assignment of contracts pursuant to which water supplies are obtained, the transfer of permits or licenses as to the water supplies, or the transfer of water rights arising out of a judgment or decree.

Step 7: Consider Unused Water Supply Assets That Could Be Monetized

To the extent the water supply rights associated with the property exceed the cannabis plants’ water demand, it may be possible to monetize unused or excess water supply assets through transfer of the rights to a third party.

If you have any questions about water rights related to cannabis cultivation it’s always in your best interest to contact an experienced water attorney early on in the process.

Summary of Practical Considerations For Cannabis Producers

Cannabis producers should establish procedures by which the technological innovations achieved by their employees are kept confidential and are quickly reported to management for consideration as to whether the innovation should be protected as a trade secret, by patent, by plant breeder’s right or not protected at all.
If a trade secret protection is desired, the producer must invoke systems that limit knowledge of the secrets to those in the company with a need to know it, and make sure that departing employees understand their obligations of confidentiality and do not take any documentation of the secrets with them when they go.
The nature of the innovation under consideration will drive the choice between a patent and a plant breeder’s right. Plant breeder’s rights only protect whole plants. Patents protect other innovations, subject to the limitations described above. Patents may be drafted to protect whole plants, albeit indirectly: a patent on genetic sequences or engineered cell can be infringed by a whole plant that incorporates those sequences or cells.
The decision as to whether to file an application for a patent or a plant breeder’s right, and in what jurisdiction(s), should be made with careful consideration of whether the producer will employ the invention/variety in its business (and in what countries), as well as the potential value of the invention/variety to other producers who may eventually become licensees of the resulting patent(s) or plant breeder’s right.
Cannabis producers must remain up-to-date on patent and plant breeder’s rights applications that are filed in the jurisdictions in which they operate so as to be in a position to identify patents and plant breeder’s rights that will potentially affect their freedom to operate. Such due diligence will also allow the producer to predict the technological and business focuses of their competitors.
Cannabis producers must select a trademark that is immediately distinctive or can quickly become distinctive of its goods and services. The trademarks ought to be fully available, in the sense that they are not in use by any competing business in any of the jurisdictions in which the producer intends to do business. Ideally, the trademark ought to be available as a domain name to ensure that there is no confusion on the Internet.
Once the trademark is selected, the cannabis producer should make consistent and extensive use of that trademark. The more consistent and ubiquitous the use, the stronger the producer’s brand and trademark will be.
The owner of the trademark must routinely conduct searches to ensure that no third party is using a trademark that is similar that of the owner. If such unauthorized use is discovered, the owner must act quickly to restrain that use or potentially license the use.
Cannabis producers ought to contract to ensure that they are the first owners or assignees of any copyright subsisting in the artwork, literature and websites the company creates or hires other to create. Producers ought also to obtain waivers of the moral rights of any authors of this work.

World Health Organization November Meeting To Review Cannabis

By Marguerite Arnold

No Comments

In a sign that cannabis reform is now on the march at the highest level of international discussion, the World Health Organization (WHO) will be meeting in November to formally review its policies on cannabis. This will be the second time in a year that the organization has met to review its policies on the plant, with a direct knock-on effect at the UN level.

According to documents obtained by Cannabis Industry Journal, including a personal cover letter over the committee’s findings submitted to the Secretary-General Antonio Guterres by Dr. Tedros Adhanom Ghebreyesus, Director-General of the WHO, the November review will “undertake a critical review of the…cannabis plant and resin; extracts and tinctures of cannabis.”

What Exactly Will The WHO Review?

The November meeting will follow up on the work done this summer in June – namely to review CBD. According to these recommendations, the fortieth meeting of the Expert Committee on Drug Dependence (ECDD) in Geneva will include the following:

Pure CBD should not be scheduled within International Drug Control Conventions.
Cannabis plant and resin, extracts and tinctures of cannabis, Delta-9-THC and isomers of THC will all be reviewed in November.
Finally, and most cheeringly, the committee concluded that “there is sufficient information to progress Delta-9-THC to a critical review…to address the appropriateness of its placement within the Conventions.” In other words, rescheduling.

Industry and Patient Impact

Translation beyond the diplomatic niceties?

The drug war may, finally, and at a level not seen for more than a century, come to a close internationally, on cannabis.

Here is why: The WHO is effectively examining both the addictive impact and “harm” of the entire plant, by cannabinoid, while admitting, already that current scheduling is inappropriate. And further should not apply to CBD.

This also means that come November, the committee, which has vast sway on the actions of the UN when it comes to drug policy, is already in the CBD camp. And will finally, it is suspected, place other cannabinoids within a global rescheduling scheme. AKA removing any justification for sovereign laws, as in the U.S., claiming that any part of cannabis is a “Schedule I” drug.

What this means, in other words, in effect, is that as of November, the UN will have evidence that its current drug scheduling of cannabis, at the international level, is not only outdated, but needs a 21^stcentury reboot.

International Implications

From a calendar perspective, in what will be Canada’s first recreational month, Britain’s first medical one and presumably the one in that the German government will finally accept its second round of cultivation bids, the world’s top regulatory body will agree with them.

This also means that as of November, globally, the current American federal justifications and laws for keeping cannabis a Schedule I drug, and based on the same, will have no international legal or scientific legitimacy or grounding.

Not that this has stopped destructive U.S. policies before. See global climate change. However, and this is the good news, it is far easier to lobby on cannabis reform locally than CO2 emissions far from home. See the other potentially earth-shaking event in November – namely the U.S. midterm elections.

The global industry, in other words, is about to get a shot in the arm, and in a way that has never happened before in the history of the plant.

And that is only good news for not only the industry, but consumers and patients alike.

Protecting Intellectual Property in Canada: A Practical Guide, Part 4

By Richard Naiberg

No Comments

Editor’s Note: This is the third article in a series by Richard Naiberg where he discusses how cannabis businesses can protect their intellectual property in Canada. Part 1 introduced the topic and examined the use of trade secrets in business and Part 2 went into how business owners can protect new technologies and inventions through applying for patents. Part 3 raised the issue of plant breeders’ rights and in Part 4, below, Naiberg discusses trademarks and how cannabis businesses should go about protecting their brand identity in Canada.

Trademarks: Protections For Brands And Goodwill

Cannabis businesses must not only protect their investments in their technical creations, but also must protect their brand identities. A cannabis producer can invest heavily in making a desirable, high-quality product, and can advertise and sell this product so as to generate customer interest and goodwill, but if the customer cannot distinguish the producer’s product from that of its competitor, this investment is for not. Trademarks become unenforceable when they are no longer distinctive.

A trademark provides its owner with the right to have the Court stop another entity from using the trademark, or using a similar trademark in a way that confuses the public. When the trademark is infringed, the Court can also make a monetary award in favor of the trademark owner.

Trademarks are identifiers of a particular source of manufacture and they can take virtually any form. Trademarks can be words, phrases, symbols, names, designs, letters, numbers, colors, three-dimensional shapes, holograms, moving images, modes of packaging, sounds, scents, tastes, textures, or any other distinguishing element. What a trademark cannot be is a mere descriptor of the goods or services themselves because such a trademark would prevent other entities from describing their products in their ordinary terms.

Trademarks can be registered, but they do not have to be. In choosing a trademark, the cannabis producer must balance competing impulses: the desire to choose a trademark that is suggestive of the product itself so as to have an immediate meaning to customers without need of an expensive marketing campaign; and the desire to coin a unique and striking trademark which is instantly eye-catching and memorable, but which must be advertised before customers can understand the product to which it refers.

For example, a depiction of cannabis leaf or a word that plays on the ordinary terms used to refer to cannabis will not make a strong mark that can be enforced against those who adopt something similar. On the other hand, a coined word, such as “Kodak”, may have no independent association with cannabis but, after a time, use of this mark in association with a cannabis product can create a very strong mark with a wider ambit of exclusivity.

All that said, even a very suggestive mark can serve as a trademark where the use of the mark is so longstanding and ubiquitous that the suggestive mark acquires a secondary meaning as an indicator of its source of manufacture. Cannabis producers can and should also consider adopting specific colors, scents or tastes of their products as trademarks, where appropriate.

Trademarks become unenforceable when they are no longer distinctive. For this reason, trademark owners must keep abreast of any use of trademarks similar to their own by third parties, and must act quickly to either license such uses or to restrain them.Cannabis businesses have been very busy applicants for trademarks. More than 1700 such applications are now on file, though a comparative few have yet been registered.

Trademarks can be registered, but they do not have to be. When a company’s product or service becomes known to its customers or potential customers with reference to a mark through ordinary business use, a trademark has been created.

Registration does however provide certain advantages. Under the amendments to the Trademarks Act coming in 2019, a registered trademark can be obtained for without any proof of use or goodwill. By contrast, and as noted above, an unregistered mark must be used and possess goodwill before it can be said to exist at all. A registered trademark provides protection for its owner across Canada. An unregistered trademark can only be enforced in the geographical area in which its owner has established its reputation. A registered trademark is protected from those who use it in a manner that is likely to depreciate the goodwill of the trademark. An unregistered trademark only protects against consumer confusion.

Registration under the Trademarks Act also makes it an offence to sell goods or services on a commercial scale in association with another’s registered trademark, or to traffic in infringing labels. Further, a trademark owner can request that the import or export of such goods in Canada be arrested. No similar rights accrue for unregistered trademarks.

Finally, a registered trademark is published at the CIPO web site, providing notice of its existence to new market entrants before these entrants commit to using a similar trademark. Unregistered marks are not always easily discovered and a new market entrant may commit to a mark before having any opportunity to discover that it is the unregistered trademark of another.

Registering a trademark is straightforward. The applicant prepares an application that identifies the applicant, the trademark and the goods and/or services with which the trademark is being used or is intended to be used. Once satisfied that the application complies with the Trademarks Act, CIPO publishes the application to allow potential opponents of the registration to come forward. If there is no opposition, or if an opposition proceeding is brought and dismissed, the trademark is issued.

There is an interaction between the Trademarks Act and the Plant Breeder’s Rights Act. As discussed above, when a denomination has been adopted for a plant variety under the Plant Breeder’s Rights Act, nothing similar can be adopted or registered as a trademark. This is so other traders may use the denomination in their sale of the variety after expiry of the plant breeder’s right.

Cannabis businesses have been very busy applicants for trademarks. More than 1700 such applications are now on file, though a comparative few have yet been registered. Trademark applications in this area are likely to increase further with the coming changes to the Trademarks Act and the removal of the requirement that applicants show use of the trademark prior to registration. Companies will be encouraged to apply for trademarks they may only be considering using, and for any trademarks that they think their competitors may be planning to use. There is some concern that the changes to the Trademarks Act will lead to the rise of trademark trolls.

Before adopting a particular trademark, the producer must do what it can to minimize the likelihood that a third party will assert that the trademark infringes the third party’s prior rights. Searches of Canadian and international trademarks, particularly United States trademarks, are advised. National intellectual property offices, such as CIPO and the United States Patent and Trademark Office, maintain easily searchable databases of registered and applied-for trademarks that should be reviewed. Search professionals can also assist in identifying trademarks that have never been the subject of a trademark application. With the result of the searches in hand, the cannabis producer can determine whether or not to proceed to adopt the contemplated mark and invest in its promotion.

In Part 5, Naiberg will explain how to use a copyright to protect works of creative expression. Stay tuned for more!

Protecting Intellectual Property in Canada: A Practical Guide, Part 3

By Richard Naiberg

No Comments

Editor’s Note: This is the third article in a series by Richard Naiberg where he discusses how cannabis businesses can protect their intellectual property in Canada. Part 1 introduced the topic and examined the use of trade secrets in business and Part 2 went into how business owners can protect new technologies and inventions through applying for patents. Part 3, below, delves into plant breeders’ rights and how breeders in Canada could protect new plant varieties.

Plant Breeders’ Rights: Protection For New Plant Varieties

Unlike the Patent Act, Canada’s Plant Breeders’ Rights Act does provide intellectual property protection for whole plants. Plant breeder’s rights are available for new cannabis plants, whether they are the product of genetic engineering or more traditional cross breeding.

The applicant must also propose a name (referred to as a “denomination”) for the new variety that is acceptable to the Commissioner.The Plant Breeders’ Rights Act focuses on the material used to propagate a new variety of plant, such as its seeds. The owner of a plant breeder’s right can stop others from selling, producing or reproducing the propagating material, conditioning the propagating material for use, exporting or importing the propagating material, repeatedly using the protected variety to commercially produce another variety, and stocking the propagating material for the purpose of doing any of the above acts. The owner can also assert these same rights to stop another’s activities as they relate to another plant variety that is essentially derived from the protected variety. The owner can also recover for the damages it suffers as a result of any infringement. For cannabis plants, the term of a plant breeder’s rights endures for 20 years from the date of its issuance.

To register a plant-breeder’s right, a breeder provides an application to the Commissioner of Plant Breeders’ Rights Office, which is part of Canadian Food Inspection Agency.

To be registrable, the plant variety must be new, meaning that the propagating material has not been sold in Canada more than 1 year prior to the application (or elsewhere more than 4 years prior to the application); it must be distinguishable from all varieties that are known to exist at date of filing of the application; it must be sufficiently homogeneous, meaning that its relevant characteristics are predictable and commercially acceptable; and it must be stable in its essential characteristics over successive generations. Registration under the Plant Breeders’ Rights Act provides plant breeders’ rights in Canada only. However, Canada is a signatory to a treaty (UPOV) that allows an application originally filed in Canada to provide priority for registration in other member countries, and vice versa.The Commissioner also has the power to require the performance of tests on a sample of the propagating material, such as to verify its stated characteristics.

The applicant must also propose a name (referred to as a “denomination”) for the new variety that is acceptable to the Commissioner. The Plant Breeder’s Rights Act puts limits on what may be chosen as the denomination. Among other things, the denomination cannot refer to characteristics the variety does not have, suggest that it is derived from another variety or bred by a particular breeder when this is not case, or comprise laudatory descriptives that could cause confusion. The denomination cannot be used or registered as a trademark and, once accepted by the Commissioner, must be used by all traders when selling the propagating material, even after the expiry of the plant breeder’s right. Indeed, the Plant Breeders’ Rights Act makes it an offence to misuse or misapply the name. The same denomination will be used for the same variety in all UPOV countries.

The application process can involve some back-and-forth with the Commissioner, as well as the opportunity for others to oppose the registration. The Commissioner also has the power to require the performance of tests on a sample of the propagating material, such as to verify its stated characteristics.

A unique feature of a plant breeder’s right is that it can be enforced even before the Commissioner finishes his or her review against infringers who are given notice of the applicant’s application.

As of this writing, there are three registered denominations of cannabis plants under the Plant Breeders’ Rights Act. Chris Griffin has registered “Big C” – cannabis sativa subsp. indica; and MedReleaf Corp. has registered MR2017001 and MR2017002, both being varieties of cannabis sativa. It is expected that further registrations will follow.

There are some important limitations to the plant breeder’s rights. Farmers who harvest the plant variety on their “holdings” are given a privilege: they can store, produce and reproduce (but cannot sell) the variety on such holdings. The Commissioner also has the power to issue compulsory licenses when a protected variety is not available to the public at reasonable rates. Further, the plant breeder’s right is not infringed when the protected variety is used for non-commercial or experimental purpose.

In Part 4 of the series, Naiberg will discuss trademarks and how cannabis businesses should go about protecting their brand identity in Canada. Stay tuned for more!
