I was wondering where more heat comes from. I'm considering putting my hoods on it's own flow of fresh air and not sucking it out of the room, through the filter, and then through the hoods. Not sure how that would affect temps. I was thinking if I did that the hoods seperate from sucking air out of the room itself, I could use a smaller fan when running co2 (if alot of heat gets sucked out of the hoods). Thoughts? w00
I draw air from inside the tent through the filter and it cools the hood/light just fine. You can run independent air to the hood but not needed. You will need to run independent air for co2 though.
