I need some ventilation advice for 1000 watt grow

[WolfScott]

Here is a little back ground on the set up and equipment so far.

I am using a room about 12x15 foot but I only have enough light to use a corner of the room for now, a 7x6foot space or a little more.

1000 watt Hortilux eye super HPS bulb
Large sized Adjust A Wing Reflector with light spreader
Crop Master 10 switchable ballast
3 fans for circulation
for exhaust I am using an 8 inch inline fan, with a carbon scrubber .

My question is;; What should I do for fresh air coming in? I was thinking a 4 inch inline fan, but will that be enough with an 8 inch sucking air out? Or should I use a 6 inch. Or is there a better easier way I'm too stoned to see?? LOL I will be taking fresh air in from another room for now,, but when the weather warms up I plan on taking fresh air from outside. Any input will be great and will earn respect! I'm almost finished setting the room up, all I need now is the fresh air intake set up and I'll be ready to grow! TY

personally i think you may be fine running passive intake aka no fan just a hole and your exhaust fan sucks air in through it from the vacuum cause im sure that fan pushes lots of air....i run passive.

nice, maybe I've been over thinking it, that makes scene, and it's cheaper too! I just may try that, I did notice in my friends room he just keeps his door open a bit and his fan sucks in enough air. My room needs to be sealed, So i will have to put a hole in the wall. Great idea thanks.

no prob and for my intake i got a hole with a board over it and some little wood scraps holding it out from the wall,you could put a piece of screen in there to as to cut down on the light getting in.
