aeroguerilla...welcome to stoner forums....
First aero grower?
Temp for a eaz that big should be between 50 to 60 degrees for good circ to the root system...at 50 to 60 % temp u get better nute delevery to ur roots so u'll be cool at that temps..
Now the air/co2 question....your gonna still need fresh air to ur plants buddy...
u can setup a timer to turn on a fresh air intake fan for a few mins a day to help with fresh co2/ I have my co2 generator setup on a timer to turn off/on when the fresh air intake fan comes on and off....so in other words have the fresh come on and the co2 turn off and vise versa...
hope this helps...if not pm me and i'll be ever so glad to help...
