This is the second part of a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, click here. Part Three comes out next week and covers prioritization and preventative measures. Stay tuned for more!
This is Part 2: Pest Monitoring, Record Keeping, & Communications
Begin your pest identification process with a pest scouting document. You have already mapped out your facility with locations and potential access locations. For each of these pest types and room type assignments (mothers, clone, veg, flower), identify your employee scouts, their scouting methods, scouting frequency and the type of likely pest they are to search for and count.
Insect Types and Tracking Methods
Insect pest types include, but are not limited to, airborne flying or crawling insects, their various egg, lymph, larvae, pupal shells or immature forms. Look for trace remnants, plant damage or feces that let you know they are present in some form. If they are at the mature jumping or flying stage, this can be harder to count, but sticky traps distributed on an even basis around your rooms can make the counting process more consistent from survey to survey.
Note airflows in your rooms and fan locations so migrations can be predicted once an infestation is located.
Insects Can Be Everywhere – Crawlers & Fliers
Insects would like to be everywhere so they come in many types from the obvious flying and crawling types to root-zone microscopic, aquatic, fungal, bacterial or biofilm based. For those of you using soil or media, root-zone insects can be beneficial by digesting and breaking down organic matter into something useful for your plant’s roots (earthworms) or harmful by feeding directly on your plant roots and sucking the life out of your plants from out-of-sight below (nematodes, maggots).
Common pests in a cannabis environment include:
White flies – Oval shaped eggs on the underside of leaves, nymphs- oval crawlers that suck on the undersides of leaves, larger stage nymphs with pupae shells as they form wings and mature white flies.
Fungus gnats – Clear eggs deposited in overly wet soil or dead plant matter. Clear or white colored larvae in the soil or media, these worm-like critters go through multiple stages of molting as they grow, eventually pupating into brown cocoons and finally small black or dark flies with clear wings that flutter around your plants and suck on your leaves.
The dreaded spider mite – Clear, hard to see eggs on the underside of your leaves. These six-legged tiny moving bubbles begin the feeding as larva, add 2 legs in the intermediate and mature nymph stages and finally the oval shaped spider mites that every grower despises, adding their webs around the tops of your plants as their nurseries suck the life out of your flowers.
Insect Transfers of Bacterial Infections
Many crawlers or fliers you may discover in your grow operation do not generate fungus or bacteria on their own. However, they do routinely pick these up along the feeding way and bring them into your shop. Sap-feeding insects like leafhoppers and aphids use their needle mouths to pierce your leaves to suck on the sap that is nourishing your greenery. These insects consume the fluids and transfer bacteria as they feed. Whiteflies fit into this category of leaf sucking bacteria carrying pests. These pests can make your healthy grow rooms look blotchy with color drained out of your canopy.
Obvious symptoms of these flying/hopping pests are sticky leaves, black fungus mold, or yellowing leaves that show up at the bottom of your plants and work their way upward as the infestation progresses. Leaf curling or plant wilting will be visible in the more advanced stages of these pests.
As if crawlers were not bad enough, invisible fungus and bacteria that get into your water supplies can be the worst challenges of any grow.
Water Sourced Bacteria
Baseline testing of your feed water is critical for any facility. This is true whether you are using surface water, well water or municipal water. Please see the water tutorials on the AEssenseGrows website for details on how to test your water sources and what to look for in the mineral content.
Regardless of your water source, bacteria can be present directly in your water supply, or it can be introduced from infected plant materials from one of your suppliers. Pythium, fusarium and the latest plague, hop latent viroid, are some of the most common threats that attack your plants from your water or soil sources. These can come from your wells, feed lines or plant materials.
Reverse osmosis (RO) is a typical method to clear water of most pathogens and bacteria using water that is pressed through filters with very small membrane apertures. These small openings usually stop impurities, salts and microorganisms. Of course, these systems come in many different types and they have to be maintained to keep their performance quality. Don’t take shortcuts on your RO system.
Once your water source is clean, strict hygiene procedures for tools, equipment and plumbing are the best way to minimize these threats to your plants downstream from your water source. These cleaning efforts are not a guarantee. Pests can still get into even the best facilities. Symptoms of these maladies vary, but root rot, stunted growth, wilting, discolored roots or leaves, and in some cases, the quick death of your plants is possible depending on the critter.
Use your scouting regimen and your data mapping to locate infestations before they expand and damage your facility. Isolate outbreaks and take appropriate measures to address the pests. We will give you suggestions on prioritization and preventative measures to take in the next chapter.
Pythium is one of the most commonly harbored soil or water carried pests. When it is present and gets into your plants through cuts, natural openings, root surfaces or leaves on weakened plants, it can be devastating. In hydroponic systems, dirty looking brown roots evolve into full root rot if not addressed. Pythium is often the cause. In soil operations, pythium often shows up as wilting or yellowing patches on leaves.
Your lab testing partners are your friends when it comes to bacterial or fungal infections. Many diseases can resemble one another. It is not hard to misdiagnose environmental stress such as overheating or overwatering for a bacterial problem. Test results are necessary to accurately diagnose a problem.
Truly Airborne Molds & Mildews
Pythium and fusarium are not just present in water. They can also be airborne. Grey mold (botrytis) and powdery mildew are also common airborne pests. Proper humidity, air movement, air filtration and sterilization using HEPA (High-Efficiency Particulate Air) filters, activated carbon filters (also filter smells) and UV light sterilization can minimize these problems in your grow. Powdery mildew is the primary evil spore in this category. Airflow and regular cleaning to discourage fungal growth is the best way to limit these pests.
In conclusion, this week
Now that we have talked about identification (and clearly, this is not an exhaustive list), we will move into how to build in the cultural methods to prevent these problems from taking hold and ruining your business. In later chapters, we will dive into prioritization, treatment and control options for infestations, finally moving into control actions and emergency response.
Your integrated management response is how you pull all of this together and use your IPM procedures to increase your profitability. For the complete white paper on Integrated Pest Management Recommendations, download the document here.
Part three comes out next week and will delve into the world of Preventative Measures. Stay tuned for more!
Last week, Gary Chambers Jr., a Baton Rouge native, launched his political campaign to run for a U.S. Senate seat in Louisiana. He took the internet by storm with his first political advertisement, a 37-second-long video where he advocates for cannabis legalization, discussing the disproportionate effects that cannabis prohibition has on communities of color.
But that’s not why he made such a splash on social media; the campaign ad made headlines as possibly the first major party candidate to smoke a cannabis blunt in an advertisement.
The timing of the video is also very intentional, lasting 37 seconds. “Every 37 seconds, someone is arrested for possession of marijuana,” Chambers says in the video. “Since 2010, state and local police have arrested an estimated 7.3 million Americans for violating marijuana laws, over half of all drug arrests. Black people are 4 times more likely to be arrested for marijuana laws than white people.”
Chambers is running against Sen. John Kennedy, the Republican incumbent with support from Trump and very deep pockets.
“Most of the people police are arresting aren’t dealers, but rather people with small amounts of pot just like me,” says Chambers. “I’m Gary Chambers, and I’m running for the U.S. Senate.” Click here to see his campaign website and make a donation.
The drug war has harmed communities of color since its inception. For decades and decades, BIPOC (Black, Indigenous, and other People of Color) have been nearly six times more likely to be arrested for drug use than White Americans, despite similar rates of use.
Over the years that legalized cannabis has proliferated across the country, the same trends of market consolidation have emerged in every state that has legalized the plant. BIPOC communities already impacted by the drug war have less access to capital and therefore less access to the cannabis industry. Cannabis market consolidation has always led to white people taking a greater market share while BIPOC communities are left behind.
The legal cannabis industry currently lacks representation of BIPOC executives, business owners, and professionals. Ernest Toney, former global marketing and partnerships manager at Marijuana Business Daily, wants to change that. He founded the BIPOC Cannabis Business Network – a membership community that is working to make the cannabis industry more accessible and profitable for BIPOC professionals and business owners.
BIPOCANN is a place to meet cannabis industry leaders, a place to exchange goods, services and ideas that promote BIPOC economic growth in cannabis, an innovation hub for unique voices and perspectives, and it’s all BIPOC-owned and managed.
In this interview, we sit down with Ernest Toney to hear about BIPOCANN and ask him some questions about what the future of the cannabis industry could look like.
Cannabis Industry Journal: Tell me about your background- how did you get involved in the cannabis industry?
Ernest Toney: I grew up in Virginia and went to James Madison University where I studied kinesiology, and sports management in graduate school. That led me to pursue a career in sports administration, beginning as a sales and marketing director for a large YMCA in the southwest, followed by a stint as a sales consultant for the Arizona Diamondbacks in Major League Baseball. Immediately prior to joining the cannabis industry, I worked at USA Ultimate – the national governing body for the niche sport of ultimate (frisbee) in the United States. During that time, I managed and scaled adult programs and events across the country. A big part of my job required collaborating with national stakeholders and creating and enforcing policies to grow the sport by making it more accessible to diverse demographics. We also worked hard to increase the commercial visibility of the sport through mainstream media, including ESPN, with gender equity being a major focus area. It was cool because looking back, I learned a lot of things during that five-year period that is directly applicable to the work I’m doing to support the cannabis industry.
But my interest in the cannabis industry became strong when I moved to Denver in 2011, a year before Amendment 64 passed. When Colorado became the first adult use cannabis market in the USA, it was an exciting time. I have always been curious about economics and how policies can impact people’s lives. I was interested in what was going to happen when the new market opened.
Early on, I followed the industry trends very closely. Living in downtown Denver, I saw firsthand the effects the cannabis industry was having on day-to-day life, like increased tourism, a housing market boom, a lot of new start-ups, dispensaries opening everywhere. It was just something I knew I wanted to learn more about.
Around 2016, I started making industry connections, but didn’t pursue opportunities until a few years later. Eventually, I was hired in 2018 by MJBizDaily to focus on new business initiatives. Some of my past successes with scaling programs, national and international event management, and community-building aligned with what they were looking for.
I started as the company’s first international marketing manager. In that role, I was responsible for driving marketing campaigns to increase the company’s global readership, event registrations, and business conference presence in foreign markets. After the first year, I transitioned to identify and manage marketing partnerships for the company – which included international and domestic media, event, and affiliate partnerships within and outside of cannabis.
I felt compelled to make a change amidst the social unrest this summer. I was doing my own protesting and volunteer advocacy in Denver, but started to see more broadly, in the cannabis industry, that cannabis executives and companies were bringing attention to the fact that the War On Drugs has been problematic for minorities and communities of color. There was greater talk about social equity programs and how they are not as effective as they should be. There was greater attention to the fact that over 40,000 people are still incarcerated for the plant that others are profiting from – and that the people behind bars are predominantly coming from communities of color. I was in a position that afforded me the opportunity to see what the composition of the global cannabis industry looked like, and I could see minority representation was lacking in business ownership, leadership positions, and more.
I thought – what is the best way for me to use my talents, insights, and knowledge to affect and change this narrative? Ultimately, I decided to start my own business. Not only was this an opportunity for me to “walk the walk,” being a black man starting a business in this industry where there is a lack of black ownership, but more importantly I was uniquely positioned to be able to educate and let people know about the opportunities to be a part of the booming industry. So, I did some brainstorming and came up with a company, which is called BIPOCANN and it stands for connecting BIPOC communities to the cannabis industry.
The work I have been doing for the last quarter includes directly recruiting people into the industry. If you are curious and want to learn more about the industry, then BIPOCANN can be the entry point. We figure out what your goals are and use the network and our resources to get you connected and figure out where you want to go. Likewise, if you are a service provider, like a graphic designer, accountant, marketer or business owner for example, that sees opportunities for your business to play a role and support it from an ancillary standpoint, BIPOCANN can be an entry point for you too.
The other component to it is working with existing businesses who are trying to make the industry more accessible. I work with existing companies and brands to create platforms that amplify voices and make BIPOC folks more visible, seen and heard within the cannabis industry. We are also helping businesses increase their profitability through diversification tactics and marketing tactics that contribute to their bottom line.
CIJ: Tell me about BIPOCANN- what is it, what are your goals with this project and how has it been received so far?
Ernest: The prohibition of cannabis has disproportionately impacted communities of color in the Americas. I alluded to this earlier, but there are more than 40,000 people behind bars in the U.S. for cannabis possession and use. There’s evidence suggesting that Black Americans are up to six times more likely to get arrested for cannabis use than White Americans despite use rates being the same. And when you look at the makeup of the professional industry, there is poor representation of business ownership by people of color. The Cannabis Impact Fund references that only 4.3% of dispensaries are Black or Latinx-owned. These problems intersect in a lot of ways.
BIPOCANN is a small business working to make the cannabis industry more accessible and profitable for BIPOC professionals and business owners. Now, I know that one company cannot change 100 years of cannabis prohibition and how policy works. But if you want to make this industry more accessible, inclusive, and profitable for those who do not have the access then there are a lot of levers to pull. Policy is one. But BIPOCANN is using more direct strategies. We actively recruit people to come in and be a part of this industry, through employment, entrepreneurship, consulting, and collaborations.
We have also created the BIPOC Cannabis Business Network, a community where members can exchange services, network, and collaborate. It’s all about creating more opportunities for BIPOC professionals and business owners, and it’s a safe space to share your experiences and to ideate. Similar to your Cannabis Quality Virtual Conference, where there was a dedicated space for BIPOC folks to be seen and heard and tell their story through your virtual panels, we use our resources and network to help advocates for equity and access be seen, heard, and find opportunities to thrive as a business owner or professional.
CIJ: How do you hope BIPOCANN will be embraced by the cannabis community?
Ernest: I think it has been received well in its first quarter of business. We have had opportunities to share our story across a lot of platforms, including multiple cannabis industry conferences, podcasts, and interviews with varied media outlets. We are in startup mode, so currently we are about building a brand, being seen, and helping people understand what we are trying to achieve. We are working towards that right now. We have had some success and folks are supporting our vision and goals.
I am hoping the cannabis industry will look at BIPOCANN as another important resource within the social equity, business development, and networking landscape. I don’t want to be seen as a competitor to the organizations and individuals who have been doing similar work in this space, for much longer, but as an ally. Some of our approaches to bring new people into the industry will include strategically aligning communities and markets where we have strong ties – such as state governments, national nonprofits, and global cannabis networks.
CIJ: Where do you see the cannabis industry making progress with respect to diversity and including people of color?
Ernest: When I look at the types of conversations and coverage the industry is having, even compared to last year, it seems like more conferences, media entities, brands, and individual leaders are tuned in and trying to figure out how they can contribute to making this industry better, more equitable and more accessible. I am seeing a lot of more attention, attempts to understand where the gaps are and what to do about it.
When I take a step back to think of all the virtual conferences that have made dedicated conference tracks or even entire programs – like the National Association of Cannabis Business’ Social Equity Conference, the Emerge Canna Conference, the Cannabis Sustainability Symposium, and the Cannabis Industry Journal’s post-election social justice panel – or weekly segments from Black leaders like Dasheeda Dawson (She Blaze) and Tahir Johnson (The Cannabis Diversity Report) — those are good signs. They are creating opportunities for voices representing underserved communities in cannabis to share their perspectives and be advocates for change.
But there is still much to do and that includes greater education about the realities, histories, and challenges BIPOC and other minority communities are facing. Going back to the NACB, they recently drafted a social equity standard for state legislatures to use as a baseline for crafting policies and provisions for social equity programs. That and resources from organizations like the Minority Cannabis Business Association, Supernova Women, Cannaclusive, Minorities for Medical Marijuana, and the Massachusetts Recreational Consumer Council, for example are some useful resources for the industry.
Wana Brands is also continuing to do good work, and it was exciting to see them become the first sponsor of the inaugural Black CannaConference by the Black CannaBusiness Magazine. That was a great example of an industry leader using their dollars, marketing resources, and company values to support an event specifically dedicated to creating, developing, and enhancing Black entrepreneurs and businesses in the cannabis industry.
“It is hard to know what even a year from now will look like.”On the policy front, we just saw on election day cannabis having a ton of success at the polls, passing in every single state where there was a ballot measure.
Arizona did a good job with having social equity provisions directly included in the language on their ballot measure. I think for the states that have yet to draft a social equity program, they can look at what has worked well in some other states and also look at what has not worked well, like loopholes that invite predatory behaviors.
I’m excited to see that Governor Ralph Northam and the Virginia Marijuana Legalization Working Group are already identifying the best ways to make a recreational market a beneficial and sustainable one, and tackling how to incorporate social equity, racial equity, and economic equity into a future legalization bill. I am looking forward to learning more after an upcoming meeting with a Working Group member. Eventually, I hope to contribute towards any social equity efforts that will benefit my home state and hometown (a high poverty community that has been at the crossroads of America’s major civil rights movements, with a correctional facility that houses an inmate population equivalent to nearly 10% of the town population).
CIJ: Where do you see the industry moving in the next five years?
Ernest: Ha-ha! It is hard to know what even a year from now will look like.
Just this week the United Nations rescheduled cannabis, which is a big deal! We also saw the U.S. House of Representatives pass the MORE Act. We are inching closer towards federal legalization in the US and I think it will happen within that five-year timeframe, and it will be contentious. There will be compromises on things some folks don’t want compromises on, there will be more big money influencing the outcomes of the industry, and there will be unforeseen or unintended consequences to whatever the federal legislation looks like. I recently moderated a panel of social equity license holders, who felt that federal legalization would harm the disproportionately impacted areas (by the War on Drugs) even more! Their preference was to see cannabis de-scheduled and remain under state control.
I think federal legalization will bring another wave of major mergers and acquisitions, similar to what the Canadian market experienced in 2019, benefiting big business over small business.“We need folks who are educated and informed about these matters to be at the policymaking level to have a fighting chance.”
CIJ: Do you think we can change that?
Ernest: There are so many things at play. The legislators need to have diverse perspectives and representation from the folks in the industry, especially people of color who can speak to the impact that a century of prohibition policies have had on their communities. Those voices and stories need to be heard, but that type of representation is grossly lacking on Capitol Hill…which is all the more reason we need leaders from the aforementioned communities to have a seat at the table when decisions are made.
I say that because a lot of time there are unforeseen consequences when policies are created, so decision makers at the federal level can learn from those of us already doing the work on the local level. I recently had a conversation with a former journalist and colleague who is currently in a cannabis regulatory role. We were talking about how policy and operations intersect with social equity. He made the points that “many markets implement license caps, which are intended to prevent oversaturation of cannabis business (the idea being that density of outlets impacts use rates, and particularly youth use rates); in theory, that’s a good policy – but it comes with very real consequences for social equity applicants (because those licenses often go to the wealthiest applicants). License caps also artificially inflate the cost of those licenses (for a transfer of ownership), which also harms social equity applicants. Lotteries are also generally the result of policy and usually have disastrous results for the social equity applicant.”
So yeah – the rare opportunity to define a new industry that doesn’t just do business as usual, that can right its historical wrongs, and that will reward the communities that have been most harmed by cannabis enforcement, is now. And we need folks who are educated and informed about these matters to be at the policymaking level to have a fighting chance. The optimist in me says “we can do it!” The pessimist in me reminds me that it is 2020 and people still believe the Earth is flat. I’ll keep pushing for change, but I also won’t be surprised if this perfect opportunity to get it right goes wrong.
CIJ: How can people get involved in BIPOCANN?
Ernest: The best way to get involved is to visit www.bipocann.com and support our efforts by becoming an individual member or business member. Not only does that give you the opportunity to connect directly with other members in our business network, but it gives you the chance to be the first to be notified about the latest projects, events, and opportunities we’re working on to change the industry, how we can. By joining, you also directly support BIPOCANN’s goals, contribute to the operating budget of a black-owned business in cannabis, and support the nonprofit partners who we allocate a percentage of monthly sales towards.
You can also get involved by subscribing to our monthly newsletter through the website or by following our social media accounts @bipocann. We are also available for speaking, media, or consulting projects that support social equity, diversity, and inclusion in cannabis. For those types of inquiries, please contact ernest@bipocann.com.
Private labelling, or white labelling, is a popular option for brands looking to enter the CBD space. This practice is where a product is manufactured by one company but branded, marketed and sold by another.
There are several companies that specialize in manufacturing end-to-end finished CBD products. They commonly provide third-party test results, certificates and data to verify the purity and potency of products created. Technically, all new brands need to do is place their label on the package and start selling! However with any new venture, establishing a successful private label CBD brand will inevitably mean various challenges need to be overcome.
Securing Quality Sources of CBD
Finding the right partners to work with is a must. The best way to source credible and trustworthy suppliers and manufacturers is to look for certifications and audits from third-party agencies. These include the Global Food Safety Initiative (GFSI), the Safe Quality Food (SQF), the United States Department of Agriculture’s (USDA) organic certification program and others.
The USDA organic certification program is a rigorous multi-step audit process to increase supply chain sustainability. Organic certification is a form of elective, self-regulation for manufacturers which consumers have eagerly welcomed into the marketplace. Look for the USDA organic seal to help identify which manufacturers are trustworthy and can produce a range of organic products.
From a consumer perspective, certifying your products as organic is an additional way to provide both supply chain transparency and increase confidence when trying new CBD products. It also provides a form of quality assurance to skeptical consumers, especially those who avidly read product labels prior to making a purchasing decision. Members of this “label reader” demographic will consistently choose organic products for the quality and transparency they provide with pure and natural ingredients.
Creating a Unique Product
Innovation and creativity will continue to be important differentiators due to the highly competitive nature of the CBD marketplace. New ingredient innovations such as water dispersible materials are big game-changers. From chewing gum to energy drinks, the opportunities for new and unique CBD products under your own private label are limitless.
There are only a handful of CBD brands who are willing, or even able, to be certified organic today. USDA certification is an opportunity for brands looking to adapt to changing consumer preferences, diversify their product offerings and invest in supply chain transparency.
In the past, product differentiators involved third-party lab testing or providing COAs — today that’s just industry standard. The USDA organic seal is becoming one of the hemp industry’s most coveted certifications because it is a product differentiator.
Building Credibility
Trustworthiness, transparency and traceability are important factors for consumers to consider when shopping for products. These factors should also be considered when producing products and while vetting vendors, partners, stakeholders and supply chain suppliers.
Credible certifications allow consumers to make informed decisions while feeling confident that they are purchasing products from reputable sources. Research has shown that today’s CBD market lacks credibility while consumers are desperately seeking comfort and are eager to purchase from trustworthy brands.
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.
