Mildew

my humidity is high in my grow room (60-80%) and one of my bigbud plants has some powdery mildew on some of the lower leaves. i run 2x400w hps and have 3 (20litre) gt205 nft tanks which wont help things ,my grow room is roughly 5ft wide 14ftlong and 7ft in height , i have a 16in oscilating fan thats on full blast when the lights are on and i have 2 rvk100 extractors taking air in and out of g,rm 24/7.


is there any way to reduce the humidity without reducing size of g,rm.????

if the mildew is only on some of the lower leaves cant you take them off and hope it doesnt come back ? just a thought.

you can get a small room dehumidifier from walmart for like $40-50. Put it on the lowest setting. I'm the opposite of you, though. I have to humidify my grow hut. If I don't, I'm at 20-25% humidity.

cheerz ppl.

dehumidifier sounds like a good option coz there cheap n do the job so will maybe get 1 and see what happens..
