I've never burned it closer than three weeks before the chop, but had conversations with a person that had to do a burn ~1 1/2 weeks before the chop with no bad effects or taste. IDK, that's a bit close for my taste, but if it's do a burn or lose the crop, you do what you have to do. Wet
Should I put the affected plants under the sulfur burner and the unaffected ones away from it, or just let them all get a dose?
I'd dose them all. Much better to assume that if one is infected, they all are. Even if they aren't showing anything. Wet
Sounds reasonable to me. My fan was off, but the exhaust and circulating fan are on the same circuit. Lights off of course. Wet
