you should be ok if your plants arent cramped touching eachother and that you have great air circulation. keep the air moving. also check your plants thourough and see if you see any white powdery blotches. if i were you i would pick up a bottle of serenade to keep handy. once you see just a small patch of mold then hit it with that stuff or else that little patch will spread like wildfire.
cigarettes42 Reviewed by cigarettes42 on . Humidity during Flowering... Well, I know lower humidity is ideal for flowering... I've read about 20-30% RH is ideal. I thought I would be all set because I live in a semi-arid climate and my humidity through veg was about 20-25%. Well now that these plants are big and transpiring they're kicking out a lot of water! I think it's about 45-55% RH now. When do you start having to worry about problems with mold? Rating: 5
