Starting a knew grow in a different room. I never been good at this part. My grow room will be 8x10x8 tall. 4 1000 watt lights I would be very appreciative if anyone can tell me the cfm's needed to exhaust the room. I would like to use more than 1 fan. I also have central air and it's in my cool basement.
Also how much co2 to pump into my room every 30 minutes.
