Question about CO2 setup

My grow room is about 8x8 hydroponic system. its about 90 degrees in there so i put a setup of co2 in there. if i have co2 do i still need my vortex fan running at all? so what im asking is basically should i still circulate my air even with my co2 setup? or should i just let co2 run with no intake/exhaust?
thanks

i think you should not use co2 and cool your grow room downnnn

intake and exhaust would do better than co2. and jus breath 2-3 big breaths onto your plant and thats enough co2 for it.

do you mean "circulating" or "venting" the air? given your temps you are going to need to continue venting hot air. if you want to add co2 you need to time the co2 to be added when your fan is off. search co2 on this site and you should find lots of details on how to do it.

CO2 is used in higher temp rooms, not as a coolant, but to facilitate more growth. The higher temps open up the stomatas (sp?), so the plants breath better, and photosynthesis increases.
CO2 in cooler rooms is less efficient. But not by a whole lot.

But the higher temps can mess with the THC quality.

CO2 shouldn't be used to cover bad temps. Fix your temps first.
All conditions should be perfect before using CO2.
A sealed lamp/cooltube w/ducting will be cheaper then a proper CO2 set up.

Circulation fans should stay on, but vent fans off. (why suck out the CO2 you just paid for?)
