You need to do the math for cubic feet per minute compared to your room size. But you also want plenty of fresh new air coming in as the old is going out. That is very important for big bud development as well as all other factors. If plenty of fresh air is not available and you think the room may run a little hot, then c02 will be your best friend for those conditions. Cheers

Power OutageNot much of a question as a disappointment... I’m one of 850,000 without power. Powers been out for 24 hours, today is Tuesday, and they are saying it might be back by Saturday. Major let down, because my plants can’t just be brought outside in the sun. Anyone else?
