Im using a 4 x 4 x 7 ft high grow tent with a 1000 watt hps. I put 8 plants in there and the humidity shot up to 75%. Ive read that anything over 60% can cause mold when flowering. And since this is my new flowering closet I need it to be up to par. Does anyone know what to do for ventilation? I have a 4 inch port at the bottom and a 6 inch directly across from the 6 inch hole im using to blow out heat from the bulb. And my temps are below 87 f.
