The Pest Toolkit: UV + PCO Technology
The Future of Clean Rooms, Clean Plants & Clean Medicine
Powdery mildew (PM), thrips, mites, fungus gnats, airborne microbes, and contaminants have challenged cultivators for decades. Today, a new era of chemical-free Integrated Pest Management (IPM) is redefining how top-tier facilities protect yield and quality.
The combination of targeted UV light and NASA-developed PCO (Photocatalytic Oxidation) + Plasma air sanitation technology is now one of the most effective, science-backed solutions for both preventing and eliminating microbial and pest pressure.
And Mammoth has been leading this UV + PCO revolution since 2018.
What Are PCO & Plasma? (NASA-Inspired Technology)
PCO (Photocatalytic Oxidation) — NASA-Developed Air Cleaning
PCO uses UV light + a titanium dioxide catalyst (TiO₂) to create highly reactive oxidizing molecules that destroy organic contaminants at the molecular level.
PCO destroys:
-
Mold spores
-
PM spores
-
VOCs
-
Odors
-
Bacteria
-
Airborne pathogens
PCO is based on technology originally developed by NASA for long-duration space missions, where clean air is critical.
Plasma (Cold Plasma / Bipolar Ionization)
Plasma generates positive and negative ions that:
-
Bind to airborne microbes
-
Break down their membranes
-
Cause them to clump (making HEPA capture easier)
-
Reduce mold and bacterial load
Plasma + PCO together create a "capture AND destroy" effect for room-wide sanitation.
Quick Guide: UVA, UVB, UVC — What’s the Difference?
| UV Type | Nanometer Range | Purpose in Cultivation |
|---|---|---|
| UVA | 315–400 nm | Plant expression, anthocyanins, terpenes |
| UVB | 280–315 nm | PM suppression, immune response, resin upregulation |
| UVC | 100–280 nm | Microbial kill (room resets only — dangerous to plants & humans if used improper) |
Why UV + PCO Works: Backed by Peer-Reviewed Science
437 nm Near-UV (Violet Light)
“Violet–blue light around 405–440 nm significantly reduces bacterial and fungal loads via reactive oxygen species (ROS).”
— Maclean et al., 2014
UVB vs. Powdery Mildew
“UV-B exposure decreases germination of powdery mildew and suppresses sporulation.”
— Janisiewicz et al., 2016
Night Treatments = Maximum PM Kill
“At night, powdery mildew loses antioxidant protection, making it highly vulnerable to UV-B.”
— Schuerger et al., 2003
UVC Kill Rate
“UVC inactivates >99.9% of fungal spores, bacteria, and viruses with extremely short exposures.”
— Kowalski, UVGI Handbook, 2009
PCO + Plasma Findings
-
PCO effectively destroys airborne microbes under real airflow conditions.
-
Plasma provides high microbial kill through ion-based oxidation.
-
Combined, they reduce VOCs, odors, spores, and bioload.
This is not marketing. It’s pure science.

-
10–30 min after lights off
Use Cases
-
UVB = With plants
-
UVC = Empty room resets only
Plants also thrive under 13/11, supported by Mammoth trials.
Benefits of UV + PCO for Growers
✔ Strong PM suppression
UV damages PM DNA; PCO destroys spores completely.
✔ Pest reduction
Thrips, mites, gnats, and microbial vectors suppressed.
✔ Cleaner air → cleaner plants
Less airborne contamination = cleaner COAs.
✔ Higher plant energy + better expression
Plants not fighting pathogens redirect energy to growth.
✔ Chemical-free IPM
No residues. No flavor impact. No COA risk.
Just physics and biology.
Safety First: UV Is Powerful — Respect It
Our Safety Recommendations
-
Use UVC only for empty rooms
-
Always use radar shutoff
-
PPE required: face shield, gloves, long sleeves
-
Avoid exposing eyes or skin
Clean Rooms → Clean Plants → Clean Medicine
UV + PCO + Plasma are now the new standard in modern IPM.
For less than $600, you can protect an entire room.
Lower microbial counts = better growth, louder terps, higher quality, and clean COAs.
Hello,
I’m looking for a technology provider that would be willing to develop and install a UVLED PCO solution for a printing company in Montreal. Our client needs to reduce its VOC emissions and we are seeking an energy efficient solution. VOC mainly come from solvent (Ethylene glycol monopropyl ether, N-propyl alcohol and N-propyl acetate). They have a 15,000 CFM exhaust system. I think we would need to develop a “reaction chamber” in which we would have many steel plates covered with TiO2 and UVLED, but I have no way of estimating the dimensions (and costs) of suche a system.
Could you help with that?
Thanks!
Good afternoon what is the price and information on your
UV-PCO?
