There is a 4" centrifugal fan exhausting the air through a carbon filter, so when I tried to use the 6" intake fan it was bringing in more air than the 4" could push out. All this equipment was previously used in closet and worked fine. I tried to adapt it all to a tent (cause I was tired of not...

I really do appreciate all the help guys! I've been researching air cooled hoods and I'm going to make my own air cooled tube hood using the Bake-A-Round pyrex tube. I did not expect so much trouble keeping the temps down since this equipment was previously used in a closet environment with...

Maybe this will help illustrate what I'm working with. I did some price shopping and the "air cooled hood only" will run me around $70 on the low end. How much of a difference in temperature can I really expect if I were to go this route?

I hear ya, but my setup is less than 100 cubic feet. Theoretically I should be able to replace the air twice per minute with 200 CFM. Since this is a tent and the old air is pushed into the room right outside the tent (rather than into the attic like my previous project) I believe this is...

Thanks for the suggestions. I will probably go with the AC since changing my intake and outake would require buying a larger carbon filter as well. I do have a 6" inline I bought for this project but it is too loud and too powerful. It makes the tent swell like a balloon b/c the centrifugal fan...

Setup is a 4X4X6 tent with 600W HPS 4" intake and 4" exhaust. It is mylar inside from top to bottom. When the light ran for 12 hours the temperature reached 104F. The HPS light is currently being substituted with two 12" x 12" LED panels which work great for veg, but not so great for flower. I...
