WHAT?
Care to back up that statement with a link or a quote or anything at all???
No, why don't you google it yourself and you will find out that he is right. Passive intake/outtake always has to be at least 3x the size of a powered one if you want equal flow rates. It's called fluid dynamics dude.

Anyways, I would just get a 10" inline exhaust fan (like the green hydro farm ones..$60?), place it up high is you can and plug it into a temperature controller. Make a passive intake...yes 3x the size...down low.

Done and done. You don't want that room air tight anyways unless your running co2

2000w over a 8' x 10' footprint = 25watt per sq ft.
There's something hinky about this entire thread.
Almost like it's a fictional grow room....???
Christ...exactly why I should have stayed off the forums. I've got plenty of proof on youtube that my garden exists...and thrives. Thanks.

*LOL, I definitely don't use 8x10 though, I was way off on that. The room is 14'x11' and I use more like 6'x4' - 8'x4' of it. The hoods are almost right next to each other so I don't get what you're questioning about the footprint.

An 8" exhaust does not require a 24" diameter hole. It requires a hole with 2-3x as much surface area. Keep in mind the area of a circle has an exponential relation to diameter. A 12" diameter hole is more than twice the size of an 8" diameter hole. By the way, anyone that said a passive intake needs to be 2-3x larger than a powered intake is 100% correct.
