im running a small closet grow, and ive been battling powdery mildew from clone. im day 35 in flowering, and things are looking very good other than the occasional mildew. in order to reduce the PM ive got a dehimidifer running constantly, which keeps my temps around 85 and the RH around 20%. im growing organically in soil, and really dont want to resort to chemicals.
everything ive seen about PM says to run humidity between 40 and 50. im wondering if im causing more harm by running the humidity so low (im still seeing new PM spots daily). my instinct tells me the lower the humidity the better in this case, but i dont have the experience to tell me whether this is the case. any input is very much appreciated
