details ... consider lay all your shit out in a line long way figure out what size piece of vent (probably square in your case) you can fit your shit in ontop of a piece of tempered glass that will hold the heft of all your lights and give ya a 2-4" gap all the way around your equipment .... lay your equipment on top of the piece of duct and trace around its "footprint" on to the duct with a sharpie put all your lights back on the piece of glass cut your holes slide the glass in the vent put a reducer on one end to 8" get a nice 8" fan to put on it and some flex conduit and pump the heat else where just my high thoughts
masterjointsmith Reviewed by masterjointsmith on . Negative/Positive Air Vent Pressure??? . So when you build vents, whether it's for a grow room, or a whole building, theres a whole scientific theory behind whether the intake or the exhaust should be more powerful, vacuum and all that stuff. I seem to remember that the exhaust should be more powerful than the intake, can anyone confirm or refute please? I've googled like mad, but I just can't find any good answers and it's time to get building a proper space... I'd be really greateful for any help. Thanks! :pimp: . Rating: 5
