My Grow Tent

I just picked up a new growlab tent and was planing on running CO2 in it. This will be my 1st time using co2 and I was thinking that I wound not have an exahust on it. Just simply connect a portable ac unit to it to keep temps down. To anyone who has tried this how much do I need to worry about smell leaking from my tent?? I was thinking a of just keeping an ozone generator running in the room where the tent is ???

im curious about this too. people say not to use an exhaust fan when using co2 because the co2 gets sucked out.

for anybody who has experience running co2 in a grow tent:

how do you run your co2 system in a grow tent??
how do you keep your temps down??
how do you control odor??
