I have an exhaust fan pulling 150CFM out of two 4" holes at the top of the box and I have 5000 BTU of cooling pumping in a 4" vent in the bottom. The air exchange is awsome right now but its when i have to cut them down and dry is where the mold took off. Guess I could put my a/c on dehumidify when I chop. I could in theory keep it at 30+ degrees RH while drying by using the a/c on dehumidify. Last grow when I cut I just let the exhaust fan naturally pull the air into the box and the RH got to 55 +/- a few degrees, which I think was my main problem. I just looked at my last grow and the plants are little further ahead than last so they might get bigger and be better off. One thing is for sure at 21 days last grow they were definatly showing sex and these babys are not so im positive they will grow bigger. I might just drop the plants lower tonight so they stretch, I know that sounds bad but having the wattage I have in this box, I think I can afford to do that.
Shit I had to quit smoking weed the last week because I caught some crazy stomach bug and I'm dying to smoke!! I can almost think and type like a normal person!! (anxiety and pain management are a different story though....)
