Before you buy: is the Hobby enough for your grow? The Hobby is our 11 W entry model for a single small tent (up to about 2×2 ft / 60×60 cm, a handful of plants). It has one third of the output of the CleanLight Pro, so every plant takes roughly three times as long to treat. For any grow room, any tent from 3×3 ft, several tents or plants in full flower, choose the CleanLight Pro (36 W). Most growers who start with a Hobby upgrade to the Pro within a season. The entry-level UV-C unit for one small tent. No chemicals, no residue. Every grower knows the feeling: you spot the first white dusting on a leaf and your stomach drops. Powdery mildew and botrytis can take hold fast, and by the time it's visible, spores are already spreading. Reaching for a chemical spray means residue on your product, stress on your plants, and pathogens that build resistance over time. The CleanLight Hobby gives home growers and small-tent cultivators a clean, chemical-free alternative. A handheld 11-watt UV-C lamp in a parabolic reflector, designed to be swept slowly through your canopy, destroying mildew spores and botrytis directly on the plant surface without harming the plant itself. How it works UV-C light at 254nm ruptures the DNA of fungi, bacteria, and viruses on contact, stopping them from reproducing. The Hobby's parabolic reflector is specifically shaped to diffuse UV light deep into dense foliage, reaching between leaves and stems where spores hide. The reflector also shields you from direct UV exposure during use. Safety glasses and gloves are included in the box. Use it as a daily preventative (regular sweeps keep spore counts low before symptoms appear) or as an early-stage curative treatment when you spot the first signs of mildew or bud rot. What you can treat Powdery mildew: daily sweeps across leaves and stems to prevent spread and knock back active outbreaks Botrytis (bud rot): treat early signs before they travel through the canopy Incoming clones: disinfect new plants before introducing them to your grow space Grow tent walls and surfaces: eliminate spores and mycelium between cycles Specifications Lamp power 11W UV-C Armature Parabolic reflector, aluminum Dimensions (reflector) 11.8" × 4.7" × 4.7" (300 × 120 × 120 mm) Net weight 1.8 kg Voltage 230V (EU) / 120V (US) Bulb lifespan 8,000 hours (replace every 2 years regardless of usage) Box includes Reflector, UV lamp, safety glasses, safety gloves, manual Chemical residue None Is the Hobby right for your grow?Only if you grow in one small tent with a few plants and you are prepared to spend roughly three times longer per plant every day than with the Pro. If you have a grow room, more than one tent, or plants that fill a 3×3 ft canopy in flower, the CleanLight Pro (36 W lamp, more than three times the power) is the unit we recommend. The Pro costs a little more and saves that difference in treatment time within weeks. Choose your voltage and add to cart. Free shipping on all CleanLight units.
