Your first line of defence against powdery mildew — no chemicals, no residue, no compromise.
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

Is the Hobby right for your grow?
The CleanLight Hobby is designed for smaller setups — home grows, hobby tents, and growers with a handful of plants. If you're managing a larger grow room or want to cover more canopy faster, the CleanLight Pro (36W, 3× the UV output) is built for that scale. But if you're growing at home and want to stop reaching for pesticides, the Hobby is where to start.

Why home growers start here
Don't let one patch of mildew take your tent
You put months into your plants. One white spot on a leaf can undo all of it. The Hobby is your first line of defence: a quick daily pass over the canopy kills powdery mildew spores before they spread — with no chemicals in your grow space and nothing on your buds at harvest.
“In the Pacific Northwest we are constantly battling mold and mildew. Once I added the CleanLight Hobby to my preventive measures, I haven't seen ANY signs of mold or mildew since — and I no longer worry about my crop testing for pesticides. Definitely worth the small investment!”

FAQ
CleanLight Hobby questions
Is 11W enough for my grow?
For a tent or small room with a handful of plants — yes. The Hobby runs about a third of the Pro's output, so plan roughly 15–30 seconds per area. Running multiple tents or a dedicated room? The Pro cuts treatment time to 5–10 seconds per plant.
How do I use it?
Let it warm up for about one minute, then sweep the light over your canopy once a day. Wear the included safety glasses during treatment.
When do I replace the bulb?
The Hobby lamp lasts 8,000 hours — replace every 2 years, 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.
