I had some powder mildew one time, in flowering, with about 14 plants. What I did was got the garden sulphur and a bunch of Qtips. Dip the Qtips in the sulphur and paint the leaves that have mildew. Took a bit of time but it was enough to control the mildew until harvest. And I didn't have to spray the buds.
Perp Reviewed by Perp on . Powder Mildew? I've read a few threads on this and have heard of: 1) DECREASED humidity, 2)DECREASED temps, 3) Mildew spray? My temperature is about 78 Degrees F. humidity seems to be fine, although I'm probably wrong if I have mildew. What can I do?? Is a dehumidefier the best option, ? I'm running several fans (about 400 CFM) for intake and exhaust and have a huge fan to circulate air over the plants. Suggest's' ?? Rating: 5
