cool, I hear good things about leds plan to switch to them when I can afford the better systems. Og aand sour strains are gonna stank badly, I grow nl which is pretty low odour and ona blocks barely contain it.
Ona stinks son, and is not fooling ANYBODY that has ever smoked/grew weed. Especially people that have grown weed, hell just them smelling the ona is a dead give away. You might as well put a note on the door because it is that obvious. Sorry to sound like a bummer but been there and done that, I've been there,"well I'm only gonna do one or two plants", well one or two plants stink when they have buds on them, imagine that!
Run a carbon filter and do any strain you wan,t just get a noise reducer for the fans and then wrap the fan with a thick blanket to help kill the noise, if noise is an issue.
Being "thrifty" and using odor agents to "mask" the smell are not worth having to rip your garden out because your neighbor commented on the dead skunk or "that dope" in the area or worse the cops coming to your neighbor's house and smell your shit in the wind.
4" carbon filter = $80
4" can fan = $130
noise reducer = $60
Not going to jail or being blackmailed by a neighbor/not so good friend = priceless.
PS. Just read ur last post, and yes you will need both intake and exhaust holes. Ideally your exhaust should be powerful enough to just pull air in through your intake, even with led, led still put off considerable heat for an enclosed space.
And just a word to the wise, Dank growing fresh has a WAY different smell than smoking weed. I can smell that smell from a mile away and behind any odor control, especially when the light goes out!!!! Trust me on the carbon filter it is worth it a million times over.
