I got a 6" hi flow fan and ran all new ducting. Crap this fan was loud in my room. I ended up mounting it in my attic hung from heavy duty bungee cords. This made it audible only from within the attic. So a few days later and I am pulling so much hot, humid air in my windows and doors of the house, that my a/c wont get things below 79 in my house. Previously I had always done full house grows, and room a/cs were standard, so I delt with heat differently. This tiny grow was using up funds, and creating stress for my lady. I picked a few brains and it was suggested I route the exhaust into my central a/c return manifold. Why didn't I think of this simple fix. Holes cut, fittings assembled, fan moved and cool room + cool house occurs. Ahhhh. Sigh of relief, and smoke a bowl.
