hey nick i got a question for ya.
so this is the first grow i have done with a carbon filter. the exhaust and filter are in the back of the flowering room air is exchanged 3 times a minute.. the entrance to the room is sealed wit plastic with zippered openings. a gap of about an inch and a half between the floor and bottom of plastic allow for new air. my basement is cold so the temp below canopy level never reaches above seventy. the plants in the back(12 ice and 12 chronic) seem to not be effected but the front group (kcbrains)where the air enters rooom seems to be stunted... is root temp my problem. the air blasts the pots of the front group. if so what is lowest ideal temp? temp at canopy level is between 75-78 wit lights on. off drops to 55-60....
