Whatsup guys, I moved back into a spot where I used to grow in the loft attic in tents, but it was always such a struggle trying to grow consistently with the extreme high/low temps of the space. I am planning on building an insulated wood room, and then setting up my 2 tents inside of the room. I am just stuck on what to do about ventilation. Here is the space I am building in:

My plan is to build my room off the studs of this wall, and to have the window at the center of it so I can stick an air conditioner in for the summer. I have a 4" and 8" inline fan, should I intake air from a room below into the grow room and exhaust into the loft? or just put a fan in each tent and duct out of the tents and out into the loft? would it be good to have air come in from just the loft space? any inpht appreciated thanks!

If heat is your major issue, I’d try and get both the intake and exhaust in the window, so you can draw in cool air and exhaust hot air. In the winter you can rearrange the intake/exhaust in the loft. Also, insulating the wall and paneling it may also help, particularly if sun shines on that wall.

thanks for the reply man, all walls are going to be insulated and sheetrocked, I figure ill have an a/c in the window for the summer and exhaust into the loft, I was just confused about in the winter time when I have that window closed, will enough air get into the room from the cracks and stuff or will I have to have a vent or something for fresh air to get in. or a vent from downstairs where the air will be warmer than the loft.

I think you’ll be fine in the winter just pulling and exhausting from the loft.
