if i air cool my lights i can put them closer to my plants which will result in better growth and conserve my lights. what i want to know is if i have my lights closer will it increase my bud production and by how much. my room is insulated so i probably could pull of a low wattage heater that would keep my room heated for a long time. im worried that when i air cool my lights my room will be to cold to have the exaust on at all times which isnt that good for my plants(to be getting fresh air all the time).
