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 Specifications Lamp power 36W UV-C (PL-L 36W) Armature Parabolic reflector, aluminum Dimensions (reflector) 15.7" × 4.7" × 4.7" (400 × 120 × 120 mm) Net weight 2.2 kg Voltage 230V (EU) / 120V (US) Bulb lifespan 9,000 hours (replace every 2 years regardless of usage) Box includes Reflector, UV lamp, safety glasses, safety gloves, manual Chemical residue None CleanLight Pro vs CleanLight Hobby The CleanLight Pro is the unit we recommend for almost every grow: a 36-watt lamp with more than three times the output of the Hobby's 11 watts, so each plant takes roughly a third of the time, and a thirty-plant room stays a daily routine instead of a chore. The CleanLight Hobby only makes sense for a single small tent with a handful of plants. If you are in doubt, choose the Pro. No chemicals. No residue. No compromises on your product. For growers who take their crop seriously (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. Choose your voltage and add to cart. Free shipping on all CleanLight units.
