Ok, I am starting up my second grow build, my first one is a simple 6x4x4 box with a 400w hps...yadda yadda yadda....but I want to make my new tent the best it can be ( money really isn't an issue)....the dimensions are 8hx4lx6.5w...pretty big tent eh?....and I will be running a 1k hps/mh switchable that will be air cooled ( I will go all out to keep this sucker cool) but that leaves me with the intake and exhaust....I will be growing 4-10 plants ( the less the better in my situation) and the ambient temps run anywhere from 70-80 indoors and 60-75 indoors at night ( maybe I should run lights at night eh?) but basically I need to know how many cfm I will need for an Exhaust, if I even need an intake and how many cfm I gotta cool my furnace with....oh and I will be having a carb filt on the exhaust ( I need it absolutely smell proof) and the light/ambient exhaust will be vented out a window with 6-18ft of ducting....thanks for taking the time to read my post.....
