So the intake smaller than the out take would this give me negative pressure?

yes, anytime you have less air going in, and more air being sucked out, that creates neg pressure.

yep spot on it gives it time to suck air out before more goes in if that makes any sense ..

so other wise if you where to have more in than going out it would be pushing that smelly air threw the sides of the tent thus why everyone goes with a smaller intake than out ..
peace

Sound mate need the smell to be hidden as much as pos lol!
