Busting the THC Myth: When it Comes to the Best User Experience, Terpenes Reign Supreme

By Mark Lange, PhD
No Comments

The scent of pine from your Christmas tree. The fragrance of a ripe summer peach at the farmer’s market. The whiff of eucalyptus and lavender that greets you when you enter a spa.

Aroma is a keystone in how we experience the world. In any given environment, aroma can help shape your mood, solidify memories and instantly transport you to another place or time.

I have focused my career on studying the fascinating compounds that are often behind these powerful aromas: terpenes. They form the largest class of natural products (compounds produced by living organisms), found in nearly all living beings. There are around 50,000 currently known terpenes in nature — with potentially thousands yet to be discovered.

Terpene-rich plants you might be most familiar with are lavender, mint, oranges (in the peel), and yes, cannabis. In recent years, terpenes have rightfully become a central discussion in the recreational cannabis world. This is because terpenes — not THC level, not “Indica-Sativa” classification — are a key determinant of cannabis’s effect, both psychoactive and non-psychoactive. But the current lack of prioritization and understanding of the crucial role terpenes play may put the collective quality of U.S. cannabis at risk.

At this crucial inflection point for legal cannabis, on its path to becoming a $70 billion dollar global industry by 2028, we need to ensure that everyone across the cannabis space, from breeders to testers, growers and consumers, understands which traits to prioritize for a cannabis world brimming with diversity and predictable effects.

What the cannabis industry has to lose 

What do we lose if the cannabis industry continues to scale without a clear understanding of the compounds that define the uniqueness of each variety?

There is a ripple effect across the ecosystem. For cannabis testing labs, focusing on only twenty of the most dominant terpenes means we are missing out on tapping into potentially over a hundred of less common terpenes in cannabis. For the cannabis consumer, lack of understanding on the breeding and testing side may make it difficult to find cannabis that delivers on its promised effect time and time again. And, most detrimentally for breeders, not understanding the direct correlation between genetics and the formation of terpenes means we will have increasingly fewer terpene profiles and combinations to work with, especially when the industry-dominant focus has been on cannabinoid potency.

Let’s explore some misconceptions related to potency. In recent years, many breeders have prioritized high THC levels over genetic diversity. Consumers often associate high THC levels and that telltale strong “skunky” aroma with a strain’s quality and effect, when in reality, these are poor indicators of potency. (In fact, recent research indicates that this specific cannabis aroma is caused by a family of sulfur compounds.) Terpene profiling is a much more accurate way to determine a variety’s given effect. In focusing too much on increasing THC, breeders miss out on the true potency powerhouse: tapping into the terpene diversity that’s out there.

Terpenes are responsible for giving flowers (including cannabis), fruits and spices their distinctive flavors and aromas. Common terpenes include limonene, linalool, pinene and myrcene.

To illustrate the impact of breeding practices that prioritize crop yield over product quality, I first have a question for you: When was the last time you enjoyed a really good tomato?

If you’re lucky enough to have a great farmer’s market nearby, maybe you purchased an heirloom tomato at peak freshness last August. It was likely fragrant, flavorful and didn’t need much preparation to be enjoyable.

Or maybe you can’t remember the last time you’ve eaten a good tomato, as the last standard grocery store tomato you purchased was watery, tasteless and essentially scentless.

Tomatoes are a prime example of what is unfortunately true for a whole host of traditional crop plants in the U.S. When yield is the goal, flavor and aroma profiles often suffer. The culprit: lack of genetic diversity in the breeding process. The tragedy of the tomato serves as a harbinger for the cannabis industry — and we can draw parallels to what we’ve seen happen to cannabis.

What the cannabis industry should do: Tap into the diversity that’s out there

An important aspect of preventing cannabis from going the way of the tomato is to better understand the genes that generate these different terpene profiles. Different cultivars with varying aromas will hold different collections of genes. We as an industry must learn more about which terpenes correlate with desirable aromas, and then access already existing genetic diversity.

We have just begun to scratch the surface of the potential of terpenes in cannabis. With the right alignment across the industry and a stronger focus on genetics in breeding, we will see the rise of completely unique cannabis varieties. They will smell like lavender, lilac, orange peel or even brand-new aromas that have yet to be discovered. To ensure this future, we need to prioritize the right traits and the right genetics.

Lab Shopping: Highlighting the Need for Checks and Balances in Cannabis

By Josh Swider

Cannabis, we have a problem. Legalizing adult use cannabis in California caused the demand for high-potency cannabis to increase dramatically over the last several years. Today, many dispensary buyers enforce THC minimums for the products that they sell. If smokeable flower products don’t have COAs proving the THC levels are above 20% or more, there is a good chance many dispensaries won’t carry them on their shelves. Unfortunately, these kinds of demands only put undue pressure on the industry and mislead the consumer.

Lab Shopping: Where the Problems Lie

Lab shopping for potency analysis isn’t new, but it has become more prevalent with the increasing demand for high-potency flower over the last couple of years. Sadly, many producers submit valid, certified COAs to the California Bureau of Cannabis Control (BCC), which show two to three times the actual potency value.

At InfiniteCAL, we’ve purchased products from dispensary shelves and found significant discrepancies between the analysis we perform and the report submitted to the BCC by the producer. So, how can this happen? Several factors are creating the perfect storm in cannabis testing.

Problems with Potency

Many consumers still don’t understand that THC potency is not the only factor in determining quality cannabis, and they are unwittingly contributing to the demand for testing and analysis fraud. It is alarming for cultivation pioneers and ethical labs to see producers and profit-hungry testing facilities falsifying data to make it more appealing to the unaware consumer.

Basically, what’s happening is growers are contacting labs and asking, “I get 30% THC at this lab; what can you do?” When they see our COA reporting their flower tested lower than anticipated, they will go to another lab to get higher test results. Unfortunately, there are all too many labs that are willing to comply.

I recently saw a compliant COA that claimed that this particular flower was testing at 54% THC. Understanding cannabis genetics, we know this isn’t possible. Another product I reviewed claimed that after diluting an 88% THC distillate with 10-15% terpenes, the final potency test was 92% THC. You cannot cut a product and expect the potency to increase. Finally, a third product we reviewed claimed 98% total cannabinoids (while only looking at seven cannabinoids) with 10% terpenes for a total of 108% of the product.

These labs only make themselves look foolish to professionals, mislead laymen consumers and skirt under the radar of the BCC with basic mathematical errors.

The Pesticide Predicament

Frighteningly, inflating potency numbers isn’t the most nefarious testing fraud happening in the cannabis industry. If a manufacturer has 1000 liters of cannabis oil fail pesticide testing, they could lose millions of dollars – or have it retested by a less scrupulous lab.

As the industry continues to expand and new labs pop up left and right, cultivators and manufacturers have learned which labs are “easy graders” and which ones aren’t. Certain labs can miss up to ten times the action level of a pesticide and still report it as non-detectable. So, if the producer fails for a pesticide at one lab, they know four others won’t see it.

In fact, I’ve had labs send my clients promotional materials guaranteeing compliant lab results without ever receiving a sample for testing. So now, these companies aren’t just tricking the consumer; they are potentially harming them.

An Easy Fix

Cannabis testing is missing just one critical factor that could quickly fix these problems – checks and balances. The BCC only needs to do one of two things:

Verifying Lab Accuracy

InfiniteCAL also operates in Michigan, where the Marijuana Regulatory Agency (MRA) has already implemented a system to ensure labs are maintaining the highest testing standards. The MRA will automatically flag all COAs which test above a certain percentage and require the product to be retested by multiple labs.

labsphotoLabs are required to keep a back stock of material. So, when test results come back abnormally high from Lab A, then Labs B, C and D are commissioned to retest the material to compare data. If Lab A reports 40% THC, but the other labs all report 18%, then it’s easy to see Lab A has made an error.

Secret Shopping

By simply buying products off the shelves and having them blind-tested by other labs, it would be simple for the BCC to determine if the existing COA is correct. They already have all the data in Metrc, so this would be a quick and easy fix that could potentially solve the problem overnight.

For example, at InfiniteCAL, we once purchased 30 samples of Blue Dream flower from different cultivators ranging in certified COA potencies from 16% to 38%. Genetically, we know the Blue Dream cultivar doesn’t produce high levels of THC. When we tested the samples we purchased, nearly every sample came back in the mid-teens to low 20% range.

Labs Aren’t Supposed to Be Profit Centers

At InfiniteCAL, we’ve contacted labs in California where we’ve uncovered discrepancies to help find and flush out the errors in testing. All too often, we hear the excuses:

  • “If I fix my problem, I’ll lose my clients.”
  • “I’m just a businessman who owns a lab; I don’t know chemistry.”
  • “My chemist messed up; it’s their fault!”

If you own a lab, you are responsible for quality control. We are not here to get rich; we are here to act as public safety agents who ensure these products are safe for the consumer and provide detailed information about what they choose to put in their bodies. Be professional, and remember you’re testing for the consumer, not the producer.

Integrated Labeling Helps This Ohio Cannabis Company Grow

By Mike Barker
No Comments

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

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

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

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

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

Compliance

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

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

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

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

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

Branding

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

Label Application – Automatic, Semi-automatic and Manual

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

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

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

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

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

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

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

Summary

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

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

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

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

California Banned Ozone Generator “Air Purifiers”

By Jeff Scheir
8 Comments

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

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

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

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

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

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

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

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

Keeping Your Environment Clean: Preventative Measures Against Contamination

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:

  1. Prevention via air and surface disinfection using germicidal UVC is much better than chemical spot treatment on the surface of plants
  2. High levels of air changes per hour enhance UVC system performance in reducing airborne spores
  3. 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 graphic 4

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.

  1. Mold and spores grow in your air handler and are present in air entering your HVAC system.
  2. Steril-Aire UVC system installs quickly and easily in your existing system.
  3. The Steril-Aire UVC system destroys up to 99.999% of mold/spores.
  4. 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.

New Taxes for California Cannabis Industry

By Jasmine Davaloo
No Comments

Welcome to the evolving world of cannabis legislation and taxation in California. With the recent 2018 midterm election, a green wave of new laws and regulations has washed ashore, and Taxnexus, a cannabis tax compliance service provider for cannabis businesses, has analyzed the results, looking for insights to guide cannabis business owners in 2019.

In summary, the trend of local counties and cities imposing new cannabis taxes on dispensaries, distributors and cultivators continues, but with some important lessons being learned.

A Brief History of California Cannabis Tax Regulations.

The legalization of cannabis in California brought with it cannabis excise tax and cultivation taxes with the hope of bringing in significant amounts of income in cannabis taxes. The state had projected $185M in cannabis tax revenue for the first six months of 2018. Although California has since collected tens of millions of dollars fewer than anticipated, it did bring in over $135M in the first and second quarters from a brand new industry.

Local governments are able to collect these taxes directly from cannabis businesses.  With the green light from the state and the need for a new source of revenue, many local governments followed suit and passed laws to impose taxes on cannabis businesses operating in their jurisdictions. The need for additional revenue is even greater for localities that allow cannabis business operations given that the state takes virtually all of the state-imposed cannabis taxes while the local government entities are burdened by the related costs of regulations and enforcement at the local level.

Cannabis business taxes have an extra allure for local jurisdictions. Unlike local sales and use taxes, the state does not require local cannabis business taxes to go through the state before a portion of it gets funneled back to the localities. Local governments are able to collect these taxes directly from cannabis businesses.

Since January 1, 2018, many local jurisdictions have come onboard and placed ballot measures for their voters to decide whether to tax cannabis businesses. According to research conducted by Taxnexus, by the end of the second quarter this year, there were over 500 different local cannabis tax rates in California.The new cannabis tax measures are also continuing the trend of widely ranging local cannabis tax laws.

Midterm Results Continue Overwhelming Support for Cannabis Industry

With over 50 cannabis tax measures placed on the November 6 local ballots, most of which passed with overwhelming support from voters, the number and variation of local cannabis business taxes continue to grow. This demonstrates the continuing trend of local governments welcoming cannabis businesses, the evolving voter attitude toward recreational cannabis, and perhaps most importantly, the localities’ desire to take their cut of the new industry’s tax revenue.

The new cannabis tax measures are also continuing the trend of widely ranging local cannabis tax laws. Given that the Medicinal and Adult-Use Cannabis Regulation and Safety Act granted local jurisdictions control over deciding their own cannabis business regulations, there is no statewide uniformity. Here are a few examples of the cannabis business tax measures that were on local ballots on November 6:

San Francisco

While some local jurisdictions were quick to impose cannabis taxes, others have delayed in taxing their local cannabis businesses. San Francisco’s Proposition D, which received a 66% voter approval, won’t go into effect until January 1, 2021. It imposes taxes on cannabis businesses that do business in the city, whether or not they are physically located there. The new cannabis business taxes are as follows:

  • For cannabis retail businesses, 2.5% of gross receipts up to $1M and 5% of gross receipts over $1M.
  • For cannabis non-retail businesses, 1% tax of gross receipts up to $1M and 1.5% of gross receipts over $1M.

These taxes do not apply to the first $500,000 of recreational cannabis gross receipts nor revenues from medical cannabis retail sales. The measure allows the Board of Supervisors to adjust the tax rates up to 7%. The cannabis businesses taxes are expected to generate $5M to $12M in cannabis tax revenue, and will go into the City’s general fund.The new tax measures underscore the lack of uniformity in local cannabis business taxes throughout the state. 

Emeryville

Emeryville passed a new cannabis business tax measure to increase its current nominal rate. Measure S imposes a cannabis business tax of up to 6% of gross receipts. This is estimated to generate $2M in tax revenue to be used for unrestricted governmental purposes.

Oakland

Oakland is among the few local jurisdictions that placed a measure on its November 6 ballot to lower its existing cannabis business tax rates. Previously, Oakland imposed a 5% tax on medical cannabis and a 10% tax on recreational cannabis, for all cannabis activities throughout the supply chain. These are among some of the highest cannabis tax rates in the state and are squeezing out small operators. Although Oakland has long been seen as the leader in California’s cannabis industry, the high taxes are making it difficult for its cannabis businesses to compete with nearby cities that charge lower taxes. While the city acknowledged the hardship its high taxes imposed, it maintained that it could not lower the rates on its own and required the voter approval. On November 6th, Oakland voters passed Measure V by 78%, which gives the City Council the authority to lower the city’s cannabis tax rates through an ordinance. To give additional relief to the cannabis businesses in the city, this measure also allows them to deduct the cost of raw materials from their gross receipts- something they cannot do on their federal tax returns. Furthermore, local cannabis business taxes can now be paid on a quarterly basis instead of one annual payment at the beginning of each year, which was severely burdensome for most businesses.

Lake County

Voters in Lake County approved Measure K by a majority vote to tax cannabis businesses in the unincorporated county effecting January 1, 2021. The county was previously only taxing cultivators at $1 to $3 per square footage depending on the method of cultivation. These rates will be reduced to $1 per square footage for cultivators and nurseries, and other cannabis businesses will be taxes between 2.5% and 4% of their gross receipts.

Mountain View

While there is a maximum of four cannabis businesses permitted to operate in Mountain View, over 80% of voters approved Measure Q to tax them. The measure imposes up to 9% of gross receipts to fund general city purposes, with an estimated annual revenue of $1M.Some have even set the effective dates of their cannabis tax laws several years out to allow their local cannabis businesses an opportunity to establish roots and drive out the black market.

Lompoc

Some jurisdictions have passed more creative cannabis business tax regimens than one rate applicable to the entire supply chain. Voters in Lompoc in Santa Barbara County approved Measure D2018 to authorize the city to impose following cannabis business taxes:

  • Up to $0.06 per $1 (6%) of recreational retail sales proceeds;
  • Up to $0.01 per $1 (1%) of cultivation and nursery proceeds;
  • An annual flat fee tax of $15,000 if net income is less than $2M of manufacturing and distribution proceeds;
  • An annual flat fee tax of $30,000 if net income is $2 Million or more of manufacturing and distribution proceeds;
  • A total aggregate tax of $0.06 per $1.00 (6%) of microbusinesses proceeds, not including medical cannabis transaction proceeds; and
  • No tax on testing.

Riverbank

There are signs that other localities that waited to jump onboard have learned from these high-taxing jurisdictions and opted for lower rates. There are even those localities that although they do not statutorily permit cannabis businesses to operate in their jurisdictions, they still want a piece of the action when it comes to cannabis taxes. The city of Riverbank in Stanislaus County currently does not allow cannabis businesses to operate without first obtaining a permit from City Hall and entering into a development agreement with the city that negotiates how much of their revenue the city would take. However, the voters just passed Measure B, which authorizes Riverbank’s City Council to impose a business license tax of up to 10% of gross receipts on cannabis businesses in the event the city allows cannabis businesses to operate within its city limits in the future. This tax has incentives other than the apparent potential of tax revenue. This guarantees the city a cut of the earnings of any illegal cannabis businesses, and serves as a protection in the event the permit and development agreement scheme the city has enacted is later found to be invalid.

The Chaos Continues

The new tax measures underscore the lack of uniformity in local cannabis business taxes throughout the state. Compliance is especially burdensome for delivery companies and multi-location and multi-license cannabis businesses. Cannabis businesses are required to keep up with new and evolving cannabis tax regimens, which, judging by the shortfall in cannabis tax revenues compared to their projections so far, is a difficult feat for these highly-regulated businesses.Of course, there are still some local governments that appear to have missed all the signs and have passed new high taxes. 

The overall trend in 2018, persisting through the midterm elections, is that more local jurisdictions are joining the cannabis tax bandwagon, and while the tax rates and structures are still all over the map, there appears to be some movement toward honing the cannabis business rates toward that “sweet spot.”

Cities like Oakland and Berkeley that immediately began to tax cannabis businesses at high rates have lowered or taken steps to lower their tax rates to keep their competitive edge and retain cannabis businesses within their jurisdictions. There are signs that other localities that waited to jump onboard have learned from these high-taxing jurisdictions and opted for lower rates. Some have even set the effective dates of their cannabis tax laws several years out to allow their local cannabis businesses an opportunity to establish roots and drive out the black market.

Of course, there are still some local governments that appear to have missed all the signs and have passed new high taxes. In due time, they, too, will give in to the market pressures and make necessary adjustments if they want to continue to benefit from the legal cannabis industry in their jurisdictions.

Maintaining an environment that supports cultivation and keeps plants healthy is not an easy task. In cannabis growing, there are a variety of factors that greenhouse managers and personnel must monitor to ensure that their plants are in a healthy environment that fosters growth and development. Temperature, humidity, lighting and CO2 levels are a few of the conditions that need to be tailored to each cannabis greenhouse operation. However, it can be difficult to constantly monitor the status of your equipment and the greenhouse environment, especially after hours or during the off-season.

A remote monitoring system that’s properly selected and installed can help greenhouse managers keep their cannabis plants healthy, multiply their yields and increase return on investment. This type of system also helps operators identify patterns and trends in environmental conditions and get insight into larger issues that can prevent problems before they arise.

Here are some tips on key conditions to monitor and what you need to consider when selecting a monitoring system for your cannabis greenhouse operation:

Temperature

Temperature plays a crucial role in any cannabis grow operation. The climate in your greenhouse must be warm enough to nurture photosynthesis and the growth of cannabis plants. Setting the incorrect temperature will significantly impact the potential yield of the plant and the rate at which it develops. A temperature too low will slow the growth of the cannabis, but too hot can lead to heat stress for your plants. The ideal temperature for a standard greenhouse is between 70 and 80 degrees Fahrenheit. However, depending on the stage of plant and desired growth densities, the temperature of the greenhouse needs to be adjusted accordingly.

Humidity Levels

Humidity directly affects plant photosynthesis and transpiration, so controlling humidity is vital in greenhouse growing. The ideal relative humidity (RH) for cannabis growth is around 60%. A low humidity level can cause water to evaporate too quickly for photosynthesis, while a humidity level that is too high can cause poor growth and possible mold and fungal disease. Monitoring the moisture content in the air of your greenhouse will help the plants during the transpiration process, increasing absorption of nutrients and overall health of the cannabis. 

Lighting

Your cannabis may be getting an abundance of natural light during the summer months, but maintaining adequate sunlight during the winter months can be a challenge. As a solution to this, many greenhouse managers equip their facilities with additional lights to supplement natural light during off-seasons or off-hours. To achieve the best possible yield, a cannabis plant in the budding stage should receive twelve hours of light each day, while other stages could require additional lighting. For example, the growth stage could require your cannabis to be exposed to sunlight for up to eighteen hours a day.

CO2 Levels

Like any other plant, cannabis requires CO2 to breathe. Greenhouse managers must set and monitor the CO2 levels in their facility to make sure that there is an adequate amount for the plants to develop, grow and be healthy. The amount of carbon dioxide required for your cannabis depends of the size of the facility and the amount of light the plants are receiving. However, a standard grow area for cannabis can maintain a CO2 range from 1000 to 1500 parts per million (PPM). A level below that threshold can result in slower growth of the plants, while a level above would lead to unused and wasted CO2.

Irrigation and Soil Moisture

One way to ensure a good yield from your cannabis is to water it regularly and monitor your soil moisture. Overwatering your plants can have the same effect, if not worse, than letting the soil become too dry. Plants’ roots need oxygen to survive, unlike leaves that breathe CO2, and when the soil is waterlogged the roots can’t provide their function. The lack of oxygen interferes with the roots’ nutrient uptake and photosynthesis causing the cannabis plant to wilt. The exact moisture content of the soil depends on the size of your greenhouse, temperature and humidity. Whether you hand water or are using a drip irrigation system, being aware of your soil moisture is vital to the long-term health of your cannabis.

Air Circulation

Your greenhouse environment should mimic the ideal conditions in which cannabis plants flourish. With an indoor facility, you have the ability to control air circulation by venting hot air out and blowing fresh air in. Creating a circulation of air inside your greenhouse will increase your cannabis plant’s growth speed and yield. Additionally, an exhaust system helps control the temperature and humidity, while also preventing the invasion of mold and pests that thrive in hot, stagnant air.

Greenhouse Security

When growing something of value, like cannabis, there will always be a threat of intruders. Whether your greenhouse is in a populated area or around hungry wildlife, any intruder could be detrimental to your overall yields and profit. Remote monitoring systems can give you peace of mind and instantly alert you when there is an unwanted presence in your greenhouse.

Knowing all the possible threats to your cannabis greenhouse helps you evaluate your specific needs, and ultimately identify the proper remote monitoring system.

Selecting the Right Monitoring System

Other factors to consider when choosing a monitoring system right for your operation include:

  • Base unit and sensors
  • Wireless or hardwired sensors
  • Communications to your site (Phone, cellular, Wi-Fi, etc.)
  • Alarm notification
  • Programming and status checks
  • Data logging
  • Return on investment

Base Units and Sensors

Each condition in your greenhouse that you want to monitor requires its own input on the base unit of the monitoring system. You must match your needs with the number of inputs available. A good fit for a smaller cannabis greenhouse may be a lower-cost, non-expandable monitoring system. However, larger facilities have many monitoring points and more people to alert when there’s a problem. If your cannabis operation is poised for growth, purchasing an expandable system could add value to the initial purchase because you wouldn’t have to replace your entire system in the future.

Your monitoring system should also have an internal rechargeable battery backup to ensure continuous monitoring and alerts in the event of a power outage. It is also recommended to have each base unit in a sheltered enclosure to protect it from moisture, dirt and other hazards.

Placement of sensors is also crucial. For example, temperature sensors in your greenhouse should be placed throughout the facility. They should be next to your thermostat and in the center of your greenhouse, preferably away from direct sunlight.

Wireless or Hardwired Sensors

Remote monitoring systems offer the option to have sensors hardwired directly to the base unit or sensors wirelessly connected. A hardwired monitoring system connects the sensors to the base device with wires. Generally, trenching long distances for wires is time consuming and costly. So alternatively, a wireless system uses built-in radio transmitters to communicate with the base unit. Some monitoring systems can accommodate a combination of hardwired and wireless sensors.

Communications to Your Site

Monitoring devices that use cellular communications must be registered on a wireless network (like Verizon or AT&T) before you can send or receive messages. Because cellular devices perform all communications over a wireless network, it is important that there be sufficient signal strength at the greenhouse. It is a good idea to check the signal quality in the area before purchasing a cellular product. If the cellular network has less than desirable coverage, it is possible to install an external antenna to help increase cellular signal.

Alarm Notifications

When monitoring systems identify a change in status, they immediately send alerts to people on the contact list. If you don’t want all of your personnel to receive notifications at the same time, certain devices can be programmed to send alerts in a tiered fashion. It is important to consider the reach of the communications, so that you’ll be notified regardless of your locations. Multiple communications methods like phone, email and text provide extra assurance that you’ll get the alert. Also, note of the number of people the system can reach and if the system automatically cycles through the contact list until someone responds. Make sure the system allows for flexible scheduling so that it doesn’t send alarms to off-duty personnel.

Programming and Status Check

If you’re responsible for maintaining a commercial greenhouse facility, you want a system that will provide real-time status of all monitored conditions on demand. There are a few different ways to access your sensor readings. Options include calling to check status, viewing a web page, either on a local network or on the cloud, or accessing the information via an app on your mobile device. With a cloud-based system, the devices supervise themselves. This means if the internet or cellular connection goes down, the device will send an alarm to alert the appropriate personnel.

If you don’t select a cloud-based system, you will be limited to logging in through a local area network, which will allow you to make programming changes, access status conditions and review data logs. If internet connectivity is not available at your location, you will want to choose a cellular or phone system rather than Ethernet-based option.

Data Logging

Sample greenhouse monitoring data log

Data history is valuable in identifying patterns and trends in your cannabis greenhouse conditions. Manually monitoring and recording environmental parameters takes a significant amount of personnel time and detracts from other important workplace demands. However, many monitoring systems automatically save information, recording tens of thousands of data points, dates and times. Cloud-based logging provides an unlimited number of records for users to view, graph, print and export data trends.

Analyzing data samples may lend insight to larger issues and prevent problems before they arise. For example, if the data log shows power fluctuations occurring at a regular time, it could be indicative of a more serious problem. Or, if the data shows signs of a ventilation fan or supplementary lighting beginning to malfunction, they can be repaired or replaced before total failure occurs.

Return On Investment

When deciding how much you should pay for a remote monitoring system, tally up the entire cost, fully installed with additional peripherals and sensors and any labor fees for installation. Then consider the value of your cannabis plant inventory and greenhouse equipment. Finally, factor in the cost of downtime, should an environmental event shut down your operation for a period of time.

Final Thoughts

Choosing the right greenhouse monitoring system and sensors could mean the difference between life and death for your cannabis plants. Understanding the conditions you need to watch and monitoring systems’ capabilities are they best way to protect your investment.
