LOL being in oklahoma ya during the hot seasons usually ac is on 24/7 anyway... It's like this, I have a spare bedroom.. 10x10x8...house is central ac/heat.. I threw a 5x5x7 grow tent in the room and it has a 630w cmh.. And a 6in carbon filter with 6in 442cfm fan inside the tent, duct work going out the top.. So it's exhausting the hot air into the bedroom.. And that's why my Temps are a bit warm I know.. But today I'm putting the exhaust duct work up thru the ceiling into the attic, so it doesn't exhaust into the room anymore... With the house central ac going the room is at 74ish(with hot tent air exhausting into room) ..tent is at 80..tent has a mesh filter screen at the bottom that I opened up, that's how the tent is getting fresh air....have a 5kbtu window unit that is going in the window to cool the room off more on hotter days (as temp outside is only 70s right now for a few days then back to 100s but not much longer) so Im sure once I exhaust the hot air into the attic my temps inside tent will lower because so will the rooms temp, and if that's not enough than I'm sure with the window unit on it'll def get where I want it to be... Again I appreciate the help man, even just talking to someone like this it gets all the shit out of my head I've been thinking about and able to discuss with someone like you, makes a big difference lol... Pretty happy with the way things are going after this convo today, can't wait to add 3 more tents.. 2 4x4x7 for flower and probablly a 2x4x4 or some shit like that for veg.. Eventually would like a perpetual grow
