Seconds a day. That's the whole routine.
Sweep the light across your canopy once a day. UV-C deactivates powdery mildew, botrytis and other pathogens on the plant surface — before they take hold. No spraying, no residues, no re-entry intervals. Use it in veg, in flower, even post-harvest.

FAQ
Questions growers ask us
Is UV-C safe for my plants and buds?
Yes — when used as directed. CleanLight has researched this extensively since 2006. Treatments last only seconds per plant, leave zero residue, and can be used through flower and even post-harvest.
How often should I treat?
Daily treatment is recommended — a brief sweep over the plant surface. For surface fungi like powdery mildew, 2–3 treatments per week can also work.
Which diseases does CleanLight control?
Fungi that grow on the plant surface: powdery mildew, botrytis (grey mold / bud rot), and other surface pathogens. Note: botrytis that has already grown into the plant cannot be cured — prevention is key.
Do you ship to the USA and Canada?
Yes. Orders over $150 ship free with FedEx and arrive in 1–3 working days. All main units are available in 120V (US/Canada) versions.
Do I need a license to use UV-C on my crop?
No. Unlike chemical fungicides, CleanLight UV-C treatment requires no license and is allowed on all types of cultivation.
