Dear great RIU minds. I wish to pick your brains

About ventilation.

I have an ideal grow room, but I cant keep it cool. Even running the AC, the ventilation is so poor it barely changes the temperature. Literally 12-15 degrees (f) difference from the rest of the house. Unfortunately, its a rental. So I cant cut any holes for exhaust. I really need some advice on this one. Any advice guys?

Are you in veg? flower? What type of lights are you using? How big is the room? It would take a little work but you could build a frame to fit into the doorway where you could duct air in and out; you just gotta be creative.

14' by 12' mate. Maybe like 10 foot high. and I only have to worry about discretion to people outside the house; I can leave the door wide open.

I just moved in here, I have seedlings about a week old. Just starting to veg. I just dont want to stress them with high temps and rape my yeild

I don't really have one nailed down. Just have 2 4' 4 bulb t5s over my girls. My last house I had the same lamps in a closet but somehow I managed the temps just fine. Now I have 4 or 5x times the room and I cant keep it under 85 without running the AC at 70 (f)

I'll take a pic in the morning it's hard to explain. It's beyond Afro-engineered.

That doesn't sound like the ideal grow room to me.

Well bro I closet grow and really font have ctrl over the heat either and nor does my AC get anywhere close to the closet but I bought 2 4ft oscallating(spelling) fans w/ inner thermometers for $40 a piece. Its keeps it pretty cool inside the closet, very comfortable. The air is always moving. Daytime 80° w/ fan 84-85° without. Night time is 4° lower. Helps out a lot.
