vent problem

o.k. here is the deal I believe this would work but I am growing in a new spot for me and stealth is of the up most here and that is the problem. Do you think that if I where to hook up to ex take vents in my grow area and no intake that it would be all right for air flow, because my fans make a bit of noise and I am growing in a way that the whole 5x4 room is unable to be seen bit if I where to put a fan for intake then it would be noticeable and cause some problems. The two fans would be rated for 50 cfm each so that would be 100 cfm total ex take. would the void that is bing filled with rushing air be enough for the plants? I do have a rotating fan in there also. Well any feed back would be great thanks.

As long as you have an opening where air is able to enter the room, using only exhaust fans is perfectly fine.

I believed so, and trust me there is ways for air to get in but not light i checked that sucker right fast. Thanks for the quick reply eh.
