This is my second grow and I have decided to use a 400w HPS this time but I'm starting to have issues with heat. First the tent is 6' x 3' x 2' and I have a ducting system to pull heat from the reflector. Im using a 70 cfm fan to pull from the the light via ducting and a glass shield on the HTG supply reflector, then a 100 cfm to push it into the attic. The tent stays about 83deg in my room with it open, but since i like sleeping in the dark I have to find a way too keep it cool. Unfortunately the tent is in my room on the 3rd floor or an apartment, so the temps are always higher. My room stays about 78-80 deg. I have recently added a windows A/C because I usually have the windows open but I'm pretty sure I see money flying out the window. Any idea how to keep a 3rd story bedroom cool? Or any ways to make my light cooling more efficient.
