CleanLight Hobby Unit | 11W UV-C at 254 nm for Powdery Mildew

The Clean Light Hobby Unit in a Small Room

An 11W lamp in a parabolic aluminium reflector, and that is the whole device. The lamp emits UV-C at 254 nm, the wavelength that damages fungal and bacterial DNA. CleanLight rate the bulb at 8,000 hours. The reflector measures 300 by 120 by 120 mm and the unit weighs 1.8 kg, so it sweeps one-handed. It ships with safety glasses, gloves and a manual. The manufacturer size it for a single small tent, roughly 2 by 2 ft and a handful of plants. Powdery mildew is the target most growers have in mind. Botrytis is the other, along with disinfecting incoming clones and wiping down tent walls. Nothing is sprayed, so nothing is left behind on the leaf. There is no residue to wash off before harvest.

How a UV-C Germicidal Lamp Treats a Canopy

Treatment is a sweep, not a soak. The lamp passes over the canopy once a day, close and moving, rather than parked over one spot. Dwell time is the thing to get right: a couple of seconds on any given leaf, held at roughly a hand's width. Longer than that and the same light that kills spores starts damaging leaf tissue. This is a preventative tool more than a rescue one. Established mildew on heavily infected growth is better removed than irradiated. The safety kit is not decorative. UV-C burns eyes and skin quickly and invisibly, so the glasses and gloves go on every time and nobody else stays in the room. Warranty runs two years from CleanLight.
