Biofilm, pathogens, and the costs of dirty irrigation systems

Published

on

Walk into most cannabis facilities and the grow rooms should (should) look clean. Plant lines under marked light, climate systems singing, nutrient programs marked to a decimal. However, inside the irrigation lines, a different story often unfolds. Out of sight, out of mind is not always applicable, unfortunately.

Biofilm accumulation in irrigation infrastructure is one of the most persistent and underestimated problems of CEA. Left unchecked, it creates the conditions for pathogen pressure, nutrient inconsistencies and costly crop losses. “However, in many operations, the solutions offered have historically come with their own trade-offs, phytotoxicity concerns, incompatibility with beneficial microbes, or less aggressive chemicals that require complete crop removal before application,” says Key Solutions Group’s Don Lund.

As the owner of Key Solutions Group, the manufacturer’s representative for PRO-OXINE® Horticulture, a unique chlorine dioxide-based chemical developed specifically for CEA environments, registered by the EPA as a disinfectant, sanitizer, algicide and fungicide and manufactured in the United States. Don is very aware of the space growers need to navigate. “There are a lot of chemicals on the market,” says Don, “and what usually happens on the irrigation side is that growers start dealing with biofilm and end up looking for something that creates phytotoxicity problems. Our chemistry is based on Integrated Disease Management (IDM) principles. The goal is to keep the growing clean from the start through prevention. We’re a science-based company, not a marketing-based one,” he says. “That makes a real difference in this space, especially for growers who have been burned before.”

One chemistry, many applications
What sets PRO-OXINE® Horticulture apart is a proprietary blend of purified sodium chlorite and highly refined oxychlorine species with dual-use flexibility, according to Don. “The same chemistry, activated on-site by a mild acid, can be spread across irrigation lines and hard non-porous surfaces. This means a single product handles what would otherwise require multiple SKUs, reducing inventory complexity and simplifying staff training.”

Activation occurs through a proprietary method, allowing for the persistent residual effect that Don describes throughout the growing cycle, a key difference from chlorine dioxide products, which tend to act in a binary mode: inactive or fully activated, while leaving mostly undesirable toxic byproducts.

“With standard chlorine dioxide, you’re either on or off,” Don explains. “Developed specifically by the manufacturer for CEA, it allows you to manipulate ppm levels while maintaining a near-neutral pH, which maintains a clean, healthy irrigation environment throughout the growing cycle, rather than hoping for the best.”

For facilities with existing biofilm problems, the protocol can be adapted accordingly. “Starting slowly or using a shock treatment at night when there are no plants, followed by a wash,” he says. “For clean operations, the focus shifts to prevention: injecting at low ppm during irrigation (2 ppm per EPA rule) keeps lines clean, nutrients effective and the root zone happy and healthy. We eliminate the need for shock between growths while being proven time and time again.”

The chemistry also addresses specific pathogen challenges that cannabis growers regularly encounter, including biofilm, fusarium, botrytis, HLVd, iron bacteria and other water sources, and algae and botrytis build-up on floors and tables. “Applications range from inlet water, storage tanks, irrigation, recycled water systems, tools, facility hard surfaces, equipment and more to disinfecting and effective sanitation with PRO-OXINE® horticulture.”

Organic word of mouth
“What’s interesting about our growth in the horticulture field is through word of mouth, as we do very little actual advertising and marketing. Our customers are our best form of marketing as they share their experiences with their industry contacts. Yes, we exhibit a few cannabis and produce CEA shows a year, however testimonials and relationship building have been very key.” Don estimates that about 90% of new business comes from existing customers recommending PRO-OXINE® to members of the Horticulture industry. It’s a dynamic that he attributes not only to product performance, but to the company’s approach to the relationship itself. “We don’t sell consumables,” he says. “We’re selling a solution through prevention…an IDM approach. The mindset is completely different. We want growers to succeed through a proven proactive approach, which is what Key Solutions Groups is all about.”

Building Nevada’s most vertically integrated cannabis operation

Published

on

By

Nevada is one of the most competitive retail cannabis markets in the United States, and Deep Roots Harvest has been betting for years that the way to win is to control everything. 11 cultivation, processing, manufacturing, extraction and retail locations all under one roof, or pretty close to it. Chris O’Ferrell, Deep Roots Harvest’s Chief Cultivator, runs the growing side of that operation in two facilities totaling 30,000 square feet, pushing 500 pounds of harvested cannabis per week and 2,000 pounds of biomass per month.

“The Source and Deep Roots harvest retail team sells 75 kilos of cannabis daily, 500 kilos weekly, over a third of which is in-house to support the High Heads, Neon Moon and CAMP brands. We cultivate, extract, process, manufacture and work the retail locations,” says Chris. “We have one of the largest market shares in Nevada in terms of retail volume and gross sales.”

That volume is produced by 60 full-time employees at the two sites, and the crop program behind it is, by any reasonable measure, built for efficiency and quality. “Many of the genetics in our library consistently exceed 100 grams per square foot, which directly helps reduce our overall cost per gram,” explains Chris. “We operate with a consumer-first approach, focusing on cost consciousness while providing tasty and competitive offerings. We operate below 70 cents per gram, a benchmark that reflects careful cost management. Getting there and staying there has required compressing costs at all input levels while continuing to invest in technology that moves the needle on quality, cost efficiency and performance.”

Genetics as intended by the producer
The transition of light is a clear example of this, as is the case with cannabis. In the beginning, the company used your classic HPS lights. As LED technology advanced, Deep Roots made the switch. However, it wasn’t just about improving energy efficiency. Chris and the team understood that the more precisely the crop was targeted, the better the final product would be. Energy savings don’t necessarily show up on retail shelves, but crop control does, in the form of flowers that express their genetics the way the grower intended.

To achieve this level of control, the spectrum became a critical tool. “We start with the spring setting, using the blue light to regulate the spacing of the interiors and control the spacing,” he explains. “As the plants progress, we move to the summer spectrum until the end of week eight, switching to a broader spectrum light with balanced wavelengths. This increases the red light, along with other parts of the spectrum to more closely replicate sunlight. We also increase the light intensity during the flowering phase to improve the plant’s photosynthetic performance, accumulation and photosynthetic activity. The parameters support the initiation of flowering, accelerate maturation and allow the plant to reach its potential they allow him to fully express his genetics.”

Nothing is left to chance
At canopy level, plants from the two largest facilities are housed in two-gallon coco pots, chosen to accommodate longer growing periods and larger plant structures. The second facility operates stone wool. Both use substrate sensors in connection with fertigation control, and track performance at different growth stages. Dissolved oxygen is injected into the root zone to increase availability, and a chlorine injection system keeps the lines clear of pathogens with a relatively inexpensive cleanup compared to conventional cleaning programs. “A chlorine injection system is relatively inexpensive to implement, replacing approximately $40,000 in other cleaning and disinfection products annually,” says Chris. “It’s all about being ahead of the curve.”

Pest management is entirely biological, implemented in conjunction with mechanical and cultural controls. “We haven’t had any pest problems,” says Chris. “This was also a decision based on reducing inputs while maintaining, if not improving, the quality of the product.”

Genetics is the backbone of cannabis operations and the gas that drives the company’s engine. They receive the same systematic treatment as all other parts of the operation. A steering committee reviews the portfolio quarterly, withdrawing underperforming cultivars and acquiring replacements based on market data from multiple markets, cross-referenced with gaps in the current menu. The criteria are repeatable agronomic performance, yield, potency, distinctive flavor profile and the ability to wash well for extraction, ensuring strong yields for both rosin and resin production. “All genetics need to adapt to the program,” says Chris. “Unique production, potency and flavor expression that fills the void of what we don’t have on the menu. It’s about finding a commercial cultivar that works well and fits the existing infrastructure. All the cultivars we grow now have a similar and predictable growth structure. The difference is the color, the smell, the experience. They are very close agronomically.”

Marijuana Reform Group Polls Consumers About Freedoms Where They Live Ahead Of 4/20

Published

on

By

Ahead of the unofficial cannabis holiday on 4/20, a leading marijuana reform group is asking consumers to take a poll about the freedoms they experience (or lack thereof) where they live.

The new 2026 Cannabis Freedom Survey from the National Organization for Reform of Marijuana Laws (NORML) includes the questions: “Where you live, how free are adults to legally possess and access cannabis?” and “Where you live, how concerned are you about the legal consequences for cannabis users?”

The survey “is designed to capture the real-time sentiment of cannabis consumers in the United States and abroad to see how individuals experience the politics of cannabis in their daily lives,” NORML said.

The the questioning It also includes a question asking people to choose “the most important step that would increase the freedom of cannabis where you live.”

Options include ending marijuana arrests, legalizing adult marijuana, allowing adults to grow their own cannabis, allowing the sale of legal cannabis, making legal cannabis cheaper, clearing records and resolving past convictions, changing federal cannabis laws and protecting consumer rights (parental, workplace, housing, health).

In addition, it asks whether respondents at the national level fully respect marijuana policy for consumer freedom, whether it is moving in the right direction, stagnant without significant progress, or regressing.

“In some jurisdictions, cannabis comes with real freedom. In others, it still comes with real consequences,” NORML Director of Development JM Pedini said in a press release. “This survey is about capturing that gap, not just what the laws say, but how people actually experience them.”

Pedini told Marijuana Moment that the organization will likely compile the results and release them a few days before 4/20.

Governor vetoes medical cannabis bill

Published

on

By











The veto pen is one of the most powerful tools in the Mississippi Legislature, and Governor Tate Reeves has used it throughout his tenure. This year, his vetoes have mostly targeted public health bills so far, with more to come.

There are three ways Reeves could handle the bills that passed both chambers. He can sign bills he supports and allow them to become law without his signature. He can also block legislation he disagrees with by vetoing a bill or part of it and deferring it to a future legislative session.

As of Wednesday, April 8, he has vetoed four bills, half as many as in the previous two sessions, but Reeves will continue to review the legislation and reject more proposals in the coming days.

Reeves vetoed two medical marijuana bills that passed the Legislature this session, dealing a fatal blow to bills that have already faced friendly chambers. One of the bills, the “Right to Try Medical Cannabis,” contained only one specific provision that Reeves disputed. The original intent of the bill, which Reeves praised, was to expand the opportunity to try medical marijuana to those with debilitating conditions that fall outside the scope of current law.
