I can tell you this for sure... you need some sort of intake to circulate fresh air. Plain and simple... should drop your temps considerably.

Have you ever tried to suck through a clogged bowl? Imagine that the passive intake hole is acting as your poking tool. Clear up that air path so your babies can breeeeeeathe. :stoned:
TheMetal1 Reviewed by TheMetal1 on . Heat-What I am doing wrong? Well I started to get heat problems with temps around 90 so I decided to add a 500 cfm exhaust fan at the top of my room to take out the heat. The problem is that it only made the temps go down like 2 degrees. Is this because I have no intake air or is my fan not big enough? My room is less than 800 sq ft. I have a 1000w light with a 180 cfm exhasut fan connected to it and the duct is very hot so I know its working. Instead of hooking up the new 500 cfm fan at the top of my room should I switch Rating: 5
