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.

Key specs

Why the starter kit?

The replacement bulb is included so you have one on hand when you need it — not scrambling for a reorder mid-cycle. The kit saves you $19.92 versus buying separately.

Is the Hobby right for your grow?

The Hobby is ideal for home growers and smaller setups — tents, compact rooms, a handful of plants. If you're running a larger dedicated grow room with multiple plants or perpetual cycles, consider the CleanLight Pro Starter Kit with its 36W lamp and 3× the UV output.

For any indoor grow, pair with the CleanLight Air for continuous airborne spore reduction alongside direct crop treatment.
