Cooling a growroom

Does anyone have any ideas on how to cool a growroom that isnt airconditioned (like an attic)? Thanks for any feedback.

A whole house fan installed in the attic would be a great help. Check out some the handyman sites.

Are you venting air in/out? Or are you just blowing it around the room?
Fresh Air is Key to a healthy grow, and a big help in cooling a room..

[SIZE=-1] Install a foil radiant barrier in the attic. Staple it to the underside of the roof rafters, allowing an air space between the foil and the roof sheathing. Place staples about 3 inches apart. Position seams between sheets of foil centered on the rafters and seal the seams with a bead of caulking compound.

see the thing is everyone I have some money to invest in my growroom.... I have already spent a lot on expensive lighting, soil, some ferts but I simply dont have the money to get a whole exhausting system. The room can become quite hot... I have a house fan going in there as we speak. Another thing is I can have some very loud system pumping away at all hours because i live with a couple people in my house and there is one that i dont want knowing about this. So I need to be somewhat stealthy and economical. Im not in any way cheap about this because in my experiences ive found you get out what you put in. I dont have the time or money to install and buy a huge system for my grow and im confident the air is somewhat fresh.... the problem is the temp. Can anyone help me out?

If you want to cool things off in an attic grow, your going to have to get an exhaust system. No way around it unless you live in Alaska

heres what i would do, 1.exhaust fan 2.intake fresh air and if its still too hot get a fan and point it at your lamp/ballast i dont have any blueprints for ya but you should get the idea

Go to Home Depot and price the attic fans they aren't that expensive. Read FAQ.

why not get a small used airconditioner?

attic fan? Im not sure Im familiar with that.... I'll look into it, thanks a lot. Hopefully it will help... Ill do everything I can short of install a very expensive exhausting system. If I could I would, you know?

Sorry Mogie, for some reason I skipped over the most important and informatable post.... thanks again, sounds like it could really help.
