Well im not to sure how i want to set this up since i dont have it all here yet. Basically what i was planning on doing is hooking up the inline fan at the top of the tent that sucks in the air of the tent with ducting that leads to a carbon filter that filters back into the tent. Then having a box fan at the bottom for air flow over plants. The hood isnt going to be cooled directly, but has a heat shield on it or tempered glass lens as it is called. I guess my question is will i need to cool the light more or is what i have in mind good. Sorry for confusion i really dont know how to word things well.
I got you. Just an idea but you may want to consider routing things so that you dont have to take up space with your carbon filter inside your tent., good idea to keep you fan out too since that will make heat as well as take up room.
My philosophy is I want as much space for my girls as possible, that means anything I can keep out of the tent I do, including exhaust fans. Cooling the light will really drop your overall temp and if you run it so the air is pulled from the tent, through the hood and exhausted through the carbon filter, you can get away with passive intake, since your tent should have air vents on the lower section and pulling that much CFM from that small of space will result in a vaccum, you should get plenty of fresh air.
