My closet is now 4.5'x4.5'x8' = 162 cubic feet
Yes I'll only keep it on for that short period of time because of heat issues I have a 400w MH for veg and a 4oow HPS for flower. It gets a little warm in there without the fans on for a period of time. Check this calculator out.

the way its setup a 20lb tank will last me 6 months. Thats using it 4 times a day at 4.5 minutes each cycle. I'm doing 18:6, doing 12:12 or 24:0 would vary in co2 usage.
