you really want a sealed run when running co2. also, you want higher temps. the higher temps increase the plants metabolic rate which allows it to use the extra co2 that you are pumping in.

at least put the fan on a timer. there's no need to waste all that co2. not to mention it's a health hazard!

good growing!
