Any words of wisdom from experienced users of UVB lights? I’ve read various posts from @St. Tom and @Mañ'O'Green as well as others and am convinced of the benefit. I just ordered the California Light Works UVB lamp. From my understanding, I will start with one 30-minute session mid-light cycle (middle of the night so I am not exposed and because my dark time is midday; my timer only has 30 minute increments). How quickly should I increase? Am I correct that my goal total uvb time is about 2 hours per 24-hr period (in 30 minute bursts)? I’ve read a wide variation of max times, so I’d rather hear from the AFN brain trust who have actually used the lights. I will be using only the last 2-3 weeks of the grow, of course. CLW advises keeping the light 3 feet above the canopy, so I’ll aim for as high as I can get above the plants (3ft will be tough with the plant height and the HLG light/infinity fan already using some vertical space).
Really appreciate everyone’s input.
