I am completiing my grow room and was wondering can you cool your lamp and exhaust your air with the same fan. I have a POWERFUL elicent 6 inch fan that really sucks out air. My grow space is only about 120 cubic feet.
Carbon filter will be used also. Room temps are great because it is in a split level home. So my grow area is slighty under ground. I have about 72- 80 degrees max in there. With a 400 hps on for an hour test temps without cooling the lens only hit 80 degrees. I have not even put circulation fans or opened a vent for the exhaust yet.

So I do not have heat issues in this space. So back to original question. Can I use my fan to cool light and exhaust growroom. I have seen a duct splitting thing that shapes like a Y. I noticed on pics here that some ducts are split. Help me out pleasekiss-ass
