Frequently Asked Questions

• WillowPure is our patented, organic cannabis decontamination system that uses precisely controlled ozone to gently, effectively, and proactively decontaminate cannabis flower and trim. WillowPure was engineered specifically for cannabis, to gently and effectively remove yeast, mold, Aspergillus, E. Coli, and Salmonella from the surface without compromising quality, flavor or effect.
• The WillowPure system converts ambient oxygen into ozone with an electrical charge. The ozone molecules then break down the cell walls of pathogens living on the surface of the plant. The ozone then breaks down back into oxygen, leaving no residue.
• All WillowPure models are manufactured in Colorado, and designed to be mobile within a cannabis facility, have a touchscreen interface and require minimal labor.

• A critical cannabis decontamination phase in which the final product is treated before testing in order to mitigate harmful pathogens. This process ensures that the product is safe for consumption, and has been used for years in industries such as agriculture and food and beverage.
• Willow is the first kill step decontamination developed just for cannabis.
• By removing pathogens proactively and before cannabis microbial testing, WillowPure ensures clean, quality cannabis, extends the shelf life of your flower, and protects your business from cannabis recalls.

• The WillowPure 360 is our flagship decontamination system designed with a gentle turning drum to ensure consistent and effective cleaning for cultivators of all sizes. It has a capacity of 27 gallons and can clean
  up to 20 pounds of whole flower per cycle.
• The WillowPure 20 is recommended for smaller batches, prerolls, and multi-strain cycles. It has a capacity of 8,500 prerolls per cycle, or up to 20 lbs of flower.

The WillowPure Ozone system provides a gentle cannabis decontamination solution that is effective in killing microbes, but does not affect terpenes or cannabinoids.

Yes! Ozone is approved for use on products labeled “organic”.

Ozone gas is triatomic oxygen (O3), a naturally occurring form of oxygen. The third oxygen atom makes the ozone molecule highly unstable, which is the key to its oxidizing power and its ability to kill a variety of pathogens, including yeast, mold, bacteria, Aspergillus, coliforms, E. Coli, and Salmonella.

That instability is also what controls biological growth of unwanted organisms much faster and more effectively than traditional disinfectants like chlorine and hydrogen peroxide. When ozone gas is used for cannabis disinfection, it penetrates the cell walls of microbes and oxidizes their cellular components, leading to their destruction.

One of ozone’s most positive characteristics is its natural ability to degrade back to oxygen. For this reason, ozone technology, rather than heat pasteurization, has become popular in agriculture and in various food and plant applications. Because it rapidly breaks back down into oxygen, ozone leaves no residue.

• Ozone applications are recognized as safe and effective when applied properly, and are compliant with FDA, USDA, OSHA, NSF/ANSI Standard 50 and UL lab standards.
• WillowPure systems are engineered to keep ozone contained at all times. Each model contains 3 levels of internal safety to ensure safe operation and efficacy.

Ozone has been used for years in industries such as agriculture, and food and beverage to make products safe for consumers. In fact, many of the fruits and vegetables you buy at the store may have been decontaminated with an ozone kill step.

You simply load the ground flower into the drum, enter your formulation into the infusion bottle, and set the infusion type and time setting. The HALO Pro aerosolizes the liquid infusion and evenly disperses them into the drum as it turns to ensure consistent and even coverage on your flower.

The HALO Pro’s precise aerosolization technology and drum rotation are intended to infuse ground flower and whole flower with the optional speed motor.

Up to 25 lbs. ground flower | Up to 12 lbs whole flower | ~11,300 pre-rolls worth of product in each cycle*.

*Actual capacity may vary depending on factors such as density, moisture content, pre-roll mass, and other variables

One batch takes about 30 minutes including a cleaning cycle.

Willow Industries provides long-term leases, rentals, and a mobile service in Colorado.

• WillowPure lease partners receive in-depth training on how to operate the WillowPure system, a microbial assessment of your facility, and continuous support from a dedicated Customer Success Team.
• WillowPure was designed as a preventative cannabis kill step. Our goal is to have our partners implement WillowPure as a preventative decontamination kill step, rather than remediation for failed flower. That is why we have built out a team of microbiologists to address contamination issues at the source in order to lower the overall bioburden on your product.

• WillowPure technology can be used by any licensed cannabis cultivator in a legal market.
• Willow Industries’ organic, patented, ozone-based technology is currently being leveraged by cannabis producers and brands in 38 states, Australia and Canada.

WillowPure Assured is an initiative by Willow Industries, designed to highlight the integrity and quality of our lease partners’ cannabis. The program represents an assurance to consumers and educates them on the care given to your premium cannabis.
