One outbreak can cost you an entire harvest. The CleanLight Pro makes sure it doesn't.
Powdery mildew and botrytis don't give warnings. They spread silently through your canopy, and by the time you see the signs, the damage is already done — lost yield, failed lab tests, and weeks of work written off. Chemical pesticides can slow them down, but they leave residue on your product, harm your plants under stress, and pathogens build resistance over time.
The CleanLight Pro uses professional-grade UV-C light to destroy the cell structure of fungi, bacteria, and viruses directly on the surface of your plants — with zero chemicals, zero residue, and no harm to the plant itself. The same UV technology used in hospitals and water treatment facilities, now built for serious growers.
How it works
UV-C light at 254nm ruptures the DNA of microorganisms on contact, preventing them from reproducing. The CleanLight Pro's 36-watt lamp delivers a powerful, focused UV dose as you sweep it slowly across your canopy. Pathogens are destroyed on the surface of leaves, stems, and buds — without penetrating the plant tissue or leaving any trace behind.
Use it as a preventative (daily passes through your grow to keep spore counts low before symptoms appear) or as a curative treatment (targeted sweeping to knock back an active outbreak and stop the spread). Many growers mount it on a light rail for hands-free daily coverage.
What you can treat
- Active powdery mildew — sweep daily across affected plants until the outbreak subsides
- Botrytis (bud rot) — treat early signs on buds and leaves to prevent spread through the canopy
- Incoming clones — quarantine and treat new plants before introducing them to your grow room
- Grow room walls and surfaces — disinfect between cycles to eliminate mildew mycelium and spores hiding in corners and crevices

CleanLight Pro vs CleanLight Hobby
The CleanLight Hobby runs an 11-watt lamp and is ideal for smaller home grows — a few plants or a single tent. The CleanLight Pro runs a 36-watt lamp with over 3× the UV output, covering more canopy per sweep and significantly cutting treatment time in larger spaces. If you're running a dedicated grow room, multiple tents, or a commercial operation, the Pro is built for your scale. The time saved every daily treatment adds up fast.
No chemicals. No residue. No compromises on your product.
For growers who take their crop seriously — whether that's clean lab results, personal standards, or protecting a large investment — the CleanLight Pro is the professional choice. It pays for itself the first time it stops an outbreak that would have cost you a harvest.

Why growers pick the Pro
Built for rooms where an outbreak costs real money
The Pro is the workhorse for dedicated grow rooms, multiple tents and commercial canopies. One daily sweep across the canopy is your insurance policy against powdery mildew and bud rot — through veg, flower and post-harvest. No residue, no re-entry interval, no lab-test surprises.
“I have been using the CleanLight Pro EVERYDAY in my medical cannabis garden for about a year and a half. Plant health is robust and the resulting flower truly could not be any cleaner or of better quality.”

FAQ
CleanLight Pro questions
How long do I treat each plant?
5–10 seconds per plant with the Pro. Let the lamp warm up for about one minute first, then sweep the light across the canopy once a day.
Can it cure an active outbreak?
Yes — powdery mildew is fully curable with daily treatment; most growers see visible reduction within 3–7 days. Botrytis is killed on the surface, but bud rot that has grown into the plant tissue cannot be reversed — daily prevention is the winning strategy.
When do I replace the bulb?
The Pro lamp lasts 9,000 hours — replace every 2 years regardless of use, because UV output fades before the lamp visibly fails. Replacement bulb →
Is it safe to use in flower?
Yes. CleanLight leaves zero residue, so it can be used from cuttings through post-harvest — including daily treatments in flower.
