How important is ventilation during nighttime? It is getting very cold where I live, and the intake fan is making my room a bit too cold when the lights are off. Can I turn off my ventilation during the plants' 'night' period?
Or should I set a timer to have the fans turn the room over a couple times in the night, and on full time during 'lights on'?
