Greenhouse hygiene programs emphasize deep-penetration sanitation during cleanouts

Published

on

During winter clean-ups, greenhouse operators prepare facilities for the next production cycle, with hygiene remaining a critical focus. Effective sanitation during crop transition plays a key role in reducing pathogen pressure and promoting long-term crop health, particularly in operations that manage virus risks such as Tomato brown rugose fruit virus (ToBRFV).

Disinfectants commonly included in greenhouse hygiene programs include Intra Multi Des GA, supplied in North America by Houweling Americas. “This product is widely used by vegetable and ornamental growers as part of comprehensive cleaning and routine sanitation strategies, especially where deep penetration is required on complex surfaces,” says the Houweling Americas team.

Getting under the surface
Biofilms and organic debris continue to limit the effectiveness of many disinfectants, harboring microorganisms in cracks, crevices, and porous materials. According to the Multi Des GA technical team, the formulation is designed to address this challenge through penetration rather than surface activity.

“Intra Multi Des GA has five active ingredients that work together to provide strong penetration properties, allowing the product to reach microorganisms hiding in difficult access areas,” the team explained. While not positioned as a dedicated biofilm remover, the formulation is intended to reveal and eliminate pathogens sheltered beneath biofilm layers.

For best results, a two-step sanitation approach is recommended: deep cleaning to remove organic matter and biofilm, followed by disinfection. “Skip the cleaning step increases the risk of completely eliminating pathogens,” the team noted, highlighting the continued opportunity for farmer education around proper hygiene sequencing.

The role of cleaning before disinfection
As part of the Intracare product portfolio, Houweling Americas also supplies Intra Foam Organics, a cleaner designed to remove organic material prior to disinfection. Organic debris can significantly reduce disinfectant performance if not completely removed, especially on high-traffic or porous surfaces. When used as a first step, cleaners like Intra Foam Organics help ensure that disinfectants can come into direct contact with target pathogens.

Performance on porous and uneven surfaces
Concrete floors, block walls and other porous greenhouse materials remain among the most difficult areas to sanitize. According to internal tests, Intra Multi Des GA works reliably on these surfaces, moving into the micro-cracks where pathogens can persist.

“When applied to porous materials such as concrete blocks, the formulation moves significantly across the substrate,” the team explained. “This behavior is different from traditional disinfectants that remain on the surface and do not reach the embedded microorganisms.”

Broad spectrum pathogen control
Growers of all types of crops rely on Intra Multi Des GA to manage a wide range of pathogens, including fungal, bacterial and viral threats. The reported efficacy against ToBRFV has made it an essential component of hygiene protocols in tomato production.

“Intra Multi Des GA has shown excellent efficacy against ToBRFV and has proven effective in eliminating the virus on contact when used appropriately,” the team reported. Beyond viral control, growers also use the product against pathogens such as Fusarium and Pythium in crop and ornamental systems.

Waste behavior and crop turnover
Unlike non-residue disinfectants, Intra Multi Des GA is designed to leave a residual effect on treated surfaces during cleaning, providing extensive protection between crops. This waste is not intended to come into contact with the collected products, but is used to maintain sanitation during downtime.

Operational efficiency is another matter. The product is applied at a low concentration of use, requires a short contact time and usually requires only one application, allowing rapid crop rotations without compromising hygiene standards.

Long-term sanitation results
Growers who consistently incorporate Intra Multi Des GA have reported cumulative improvements in crop rotation hygiene programs over multiple seasons. In one documented case, a Dutch tomato operation managing ToBRFV reported no subsequent infections after integrating the product into the cleaning protocol.

“Starting clean remains one of the most effective ways to reduce the risk of early cycle infection,” the team emphasizes.

Supporting North American producers
Houweling Americas supplies Intra Multi Des GA and other Intracare solutions through established distribution partners and provides technical support to assist with implementation. In addition to hygiene products, the company’s portfolio includes nutrient solutions, growing substrates, LED lighting, water treatment technologies and biostimulants such as Intra Eco Shield, with Intra Boost, a next-generation willow bark-derived biostimulant, scheduled for a North American launch in early 2026.

Based in British Columbia and Ontario, Houweling Americas works closely with growers to develop integrated solution programs that support yield, plant health and resilience. The company is part of Royal Houweling, a Dutch family business founded in 1925 and recently recognized with royal status for its long-term commitment to horticulture and sustainability.

For growers seeking technical guidance on hygiene protocols or product performance, the Houweling Americas team encourages direct engagement for further assistance.

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.
