Greenhouse hygiene programs emphasize deep-penetration sanitation during cleanouts

Published

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.

Indiana Lawmakers Approve Bill To Restrict And Regulate Hemp THC Products

“In India, we would like some certainty about these products so that those who manufacture and sell them know what our laws are.”

By Leslie Bonilla Muñiz, Indiana Capital Chronicle

Indiana lawmakers want state legislation to join the recently enacted federal ban on intoxicating and synthetic hemp products to counter the growing delta-8 industry.

Lengthy and complex legislation would also regulate less potent products that pass statutory muster.

But, “there will be no demand” for products below the proposed threshold, said Justin Swanson, representing the Midwest Hemp Council and 3Chi, a THC products retailer.

THC is the active ingredient in marijuana.

Sen. Aaron Freeman, R-Indianapolis, admitted to the committee that he would prefer to “wipe all these things off the planet, period,” but that his proposal is “whatever is possible.”

His Senate Bill 250 would mimic Congress’s shutdown of what Freeman described as the “Farm Bill loophole,” referring to 2018 legislation that defined legal hemp as any part of the plant that contains less than 0.3 percent delta-9 THC by dry weight. That definition allowed products containing delta-8, THCA and other intoxicating cannabinoids to proliferate, including in Indiana.

A federal funding law passed in November specifies that all types of THC count. It also limits THC products to just 0.4 milligrams per container, and completely bans those made in labs.

“I think (that’s) what the federal government wanted when they passed the Farm Bill in 2018; I think that’s what everybody had in mind when they copied that language here in Indiana,” said Chris Daniels, chief traffic safety resource attorney for the Indiana Prosecuting Attorneys Council. “The target was very low potency THC.”

An industry group supported the changes.

“It is imperative that Indiana act to align with federal policy in the 2026 legislative session,” said Cory Harris, representative of the American Cannabis and Hemp Trade Association. “Failure to do so means that Indiana’s policy will be stricter than federal law, making Indiana a legal cannabis market.”

The federal provisions will go into effect in November. Freeman’s bill repeats those provisions, but puts them into effect four months earlier, in July.

“It’s sweet that Indiana codified a federal law that will decimate an entire industry in the state,” Swanson said. “The landscape is still unsettled.”

U.S. Rep. Jim Baird — a Republican representing Indiana — introduced a proposal to push the effective date of the federal ban to 2028. President Donald Trump also signed an executive order to expedite the reclassification of marijuana as a less dangerous and less restricted drug.

Swanson said his clients support a “responsible regulatory framework,” and told lawmakers that “the status quo is not acceptable to anyone.”

Freeman’s invoice spends dozens of pages specifically regulating low-THC “hemp-derived cannabinoid products” that would be legalized, primarily with a long-standing 21-and-over requirement.

It also puts the Indiana Alcohol and Tobacco Commission in charge of regulating the rest of the industry, establishing four types of licenses for manufacturers, distributors, retailers and carriers. They would be prohibited from advertising within 1,000 feet of schools, playgrounds and others, with retailers prohibited from operating within the same radius.

Retailers would not be able to deliver products or allow customers to consume them on the spot. Selling the products online would also be illegal, another sticking point for advocates.

Dave Colt, CEO and co-founder of Sun King Brewery, said his homegrown company spent months and more than $100,000 on equipment, research and development for its THC seltzer. Amid declining alcohol sales nationwide, seltzers have allowed Sun King to retain its employees and even grow.

“We also make products for at least a dozen Hoosier small businesses. Without that additional revenue, we would be forced to lay off people and reduce our business significantly,” Colt stated. “We believe the industry wants clear regulations to meet consumer demand.”

Other provisions relate to packaging, labeling and testing.

A fiscal impact study by the nonpartisan Service Agency estimated a financial impact of half a billion dollars annually for ATC to administer and enforce the proposal. The agency will have to hire at least one excise officer in each of the six districts plus Marion County to investigate complaints related to the new regulatory framework.

There will be additional costs for law enforcement training, procurement and online databases, the analysis noted.

The costs could be offset by the permit and other fees collected. The measure would allocate 70 percent of the proceeds to ATC administrative efforts, 20 percent to enforcement, 5 percent to the state’s 988 suicide and crisis hotline and 5 percent to the general fund.

If all tobacco sales certificate holders applied for a retail permit, for example, their application fees would generate $2.1 million. If all are approved, the state would earn an additional $4.6 million, according to LSA’s analysis.

The state seed commissioner would handle licensing for hemp growers and handlers.

Freeman also included a sentence that prevents the Indiana code from immediately reflecting the federal reclassification of marijuana, if that goes forward.

“This bill simply says that we’re not going to automatically follow what the federal government does, that we, the 150 of us, would make that decision, not the federal government for us,” Freeman told his colleagues.

The Senate Commerce and Technology committee also approved an amendment to eliminate an excise tax, as all revenue-raising provisions must be initiated in the House.

The revised legislation passed on a 7-2 party line vote, but the next bill must pass through the Senate Appropriations Committee before going to the House floor.

Previous efforts to ban and regulate intoxicating hemp products have failed.

Asked about his chances this year, Senate Republican Leader Rodric Bray told reporters, “I don’t have that crystal ball,” but added, “I think the bill is in pretty good shape right now.”

“I think in Indiana, we would like some certainty about these products, so that those who manufacture and sell them know what our laws are,” he continued, “and, most importantly, to build in some really meaningful protections for our young people across the state.”

In Colorado Springs, where the landscape of legal cannabis is centered around medical use, BioMeds Weed Dispensary Colorado Springs has become a destination for patients seeking high-quality cannabis products and a fair and respectful retail experience. Located at 2301 Rand Avenue, BioMeds has developed a reputation for prioritizing product integrity, patient education and consistent service in response to the brightest trends found in recreationally oriented markets.

Unlike recreational dispensaries, where the volume and variety can sometimes overwhelm, BioMeds takes a deliberate approach. The dispensary offers a good selection of medical cannabis products, including a variety of delivery formats to suit your health needs. These typically include flower strains, tinctures, capsules, topicals, and ingestibles, allowing patients to explore therapeutic cannabis without relying on inhaled methods.

BioMeds understands that patients arrive with different experiences, preferences and conditions. To meet these needs, the dispensary emphasizes informed, non-judgmental customer service based on product knowledge. The staff is trained to explain how different formats work, as well as interpret cannabinoid ratios, identify common terpenes, and select products that match specific wellness goals.

BioMeds’ product selection is part of the reason patients turn to cannabis. For many, whole flower remains a must-have choice, especially strains that emphasize CBD content, balanced proportions or effect-specific terpene profiles. BioMeds often sells indica, sativa, and hybrids with specific labeling, allowing patients to make informed decisions about onset time, duration, and expected outcome. Beyond flower, tinctures and capsules offer discreet, dose-controlled ways to incorporate cannabis into your daily wellness routine, especially for those managing pain, inflammation, or neurological conditions.

Topicals are also a key part of BioMeds’ offering. These include cannabinoid-infused creams, salves, and lotions intended for topical use. Patients dealing with joint discomfort, muscle tension, or skin conditions often turn to topical products for their non-toxic effects and targeted relief. These products also serve as an entry point for patients exploring cannabis for the first time, especially when faced with systemic or psychoactive effects.

Another category that sees sustained interest in BioMeds is ingestion. These may include low-dose edibles, oils, or beverages tailored to patients seeking long-lasting, absorbed beverages. While recreational edibles in Colorado may gravitate toward high-THC formats, medically focused dispensaries like BioMeds ensure that low-dose, balanced-ratio, CBD-rich formats are available and clearly labeled. Many patients prefer longer-lasting edible formats, especially for managing symptoms at night or for relief throughout the day.

Compliance is a pillar of BioMeds’ operating philosophy. As a medical-only dispensary, the group complies with all Colorado Department of Public Health and Environment (CDPHE) guidelines. Patients must present a valid marijuana card, and all transactions are recorded and monitored according to state protocols. BioMeds does not allow recreational sales and maintains internal training programs to keep employees up-to-date on evolving regulations, labeling requirements and patient protection.

While the dispensary may not offer flashy promotions or themed events often seen in the recreational market, it has placed a special emphasis on medical integrity and personalized service in the Colorado Springs cannabis landscape. For patients who prioritize results over hype, BioMeds offers a consistent experience with proven products and a team that truly understands the nuances of using medical cannabis.

Behind the scenes, BioMeds maintains strong supplier relationships to ensure product availability and freshness. Inventory is regularly reviewed and rotated, and the team communicates directly with manufacturers to maintain transparency around sourcing, testing and packaging. The dispensary favors small and medium-sized Colorado growers who focus on consistency and compliance, with many products undergoing third-party lab testing for cannabinoid content, residual solvents and microbial contamination.
