You didn't mention if you have an exhaust fan to vent the humid air, if you don't have one, get one. I use "go nats" for my nat problem. And thanks, I didn't know about serenade.

Remember, unless you are using CO2 your babies need fresh air and plenty of ventilation. I've heard that you can also burn sulfer to address PM and mold issues, a buddy of mine swears by this method.

oh, and yes, plants can become wind burned!!
pappabear Reviewed by pappabear 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
