does anyone grow sealed using no co2? how often do you vent?

i ask that because here the outside temps reach into the 100's and so if i vented to often the temps wont stay down.

i plan on using a split unit ac where the condenser sits outside and the heat exchanger is in the room. here is a link below

once plants get a sorta big, iv heard they use 1sq ft. of O2 per hour. this is just hear say tho, IMO its more like 1 sq ft. per 3-5 hours. so it really depends on the size of your room.
