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 Starter Kit (36 W). Most growers who start with a Hobby upgrade to the Pro within a season. Everything you need to start protecting your home grow from day one. Powdery mildew doesn't care how much time you've put into your plants. One missed week and it spreads fast: across your canopy, between your plants, into your next cycle. The CleanLight Hobby Starter Kit gives you a complete, chemical-free crop protection setup straight out of the box: the CleanLight Hobby device plus a genuine replacement bulb, so you're covered for the first two years of use without a second order. What's included CleanLight Hobby: 11W UV-C handheld crop protection device 1× Replacement bulb: genuine CleanLight UV-C lamp (8,000-hour lifespan) How it works UV-C light at 254nm penetrates the cell walls of mould spores and bacteria, rupturing their DNA so they can't reproduce or spread. No chemicals. No residue. No harvest impact. The Hobby's parabolic reflector concentrates UV light deep into foliage for effective treatment even in dense canopies. One daily pass over your canopy (roughly 2–3 minutes per plant) is enough to keep powdery mildew and botrytis in check throughout the growing cycle.
