Is it possible for a 4inch inline to cool a 1000 watt cool tube and a 4x4 tent suckin through a carbon filter?? Seems like no. But why would they sell a 48x48x76 tent with only 4" exhaust ports?? Doesn't make sense. I'm going to have to buy the tent and cut a 6" exhaust port in the top to cool my 1000w cooltube. Such a pain in the arse!
