Try to pull your intake air from the living space, which I assume is a comfortable temp.
Exhaust to outside is good; don't forget your carbon filter!
Insulating the attic is also important. I live in a Victorian with a walk-up attic that is insulated really poorly, with a big window that catches afternoon sun... it's blisteringly hot up there some days, and I fought high temps every time I tried to stink up my attic Do you have a way to reduce heat entering the attic, such as putting up blinds on any window you might have, and keeping the attic door closed in summer so heat from the house can't get up there? Then you'd need to think of how to get your cool intake air to the tent.
You're getting plenty of solid advice here! Good luck!
stinkyattic Reviewed by stinkyattic on . Heat-What I am doing wrong? Well I started to get heat problems with temps around 90 so I decided to add a 500 cfm exhaust fan at the top of my room to take out the heat. The problem is that it only made the temps go down like 2 degrees. Is this because I have no intake air or is my fan not big enough? My room is less than 800 sq ft. I have a 1000w light with a 180 cfm exhasut fan connected to it and the duct is very hot so I know its working. Instead of hooking up the new 500 cfm fan at the top of my room should I switch Rating: 5
