Venting/CO2 and Heat

I am putting together a new grow area.

It will be 2 8x8x8 rooms divided by a 4x8x8 room and will be completely sealed.

How do I vent the heat, and still use co2? I do want to install an a/c unit in the 4x8 room and duct into the grow rooms. Will I be draining the co2 out of the room? Any advice?

it depends on what kind of ac you are using, if its a portable single hosed one you will be sucking out the co2 therefore you need a dual hose a/c. heat wise i have a 8x8 with 2 1ks in it. i have a inline fan on 24/7 because of heat and a/c on 24/7. hope this helps you

LOL ref, I asked you a similiar Q on your thread.

So what i'm going to want to buy is the dual hose a/c. How do they hook up? Will I be able to place the a/c in the 4x8 room and duct both intake and exhaust from each grow room? I guess what i'm asking is should I be recirculating the air in the rooms via the a/c unit?
