That is one of the perks of this job, you can set your schedule to suit your nature. I am by nature a night owl and that works for me since it's cheaper to cool at night as well.
True!... but Im running lights out at night.. This room is inside of an well insulated building, so I don't see but maybe a 5 degree temp swing during lights off. I have better control during lights on (daytime), this cool weather sure helps. If the temps start creeping up during the day, I can dial back the intake fan to like 35%, and turn on the AC. .. Which I really haven't had it on lately because it's been pretty cool out. This is the best, or should I say efficient time of year to grow. By the time the next 8-9 weeks roll by, we'll have to use the AC more, but at least I'll be awake and can adjust as necessary. LOL.
