The place I want to make my room will have light in the same area. How can I make a passive intake that will let air in and keep the light out? I don't think just having a duct at the bottom will do it
i have the perfect solution, i made them myself...how much air do u need to move?

^ PVC pipe works, or you can also try making another style light trap with a box/ whole in the wall of the box.
the room will be 6x6, just above 200 cf. It will have about 1600w or more, 600 now. It is in the basement.
I got a pair of used 550 cfs(or m, can't recall), will use one of them as exhaust. They just can't push air through ducts, will burn out, designed to cool computers.
I will try to hook it up thru a duct fan thermostat from home depot so its not running all the time.
Would you mind sharing your idea, mazand?
And thanks for the other comments, and suggestions, i will look those up too

well you have a little bit larger room than mine because mine is a small cabinet but just keep in mind that light cant travel around corners, i seen this youtube video where this guy built some light trap boxes and i redid his idea, im sure you can up the scale and do your own even bigger.....i have these small PC fans ive encased with believe it or not foam posterboard...
build a small square with 4 wall around 6 inches high all around the fan.then inside this makeshift box start hot glue gunning baffles insides where air can travel around but not light, like staggerred pieces, so the air has to snake around. first two small vertical walls so there isnt a piece of foam board right against the face of the fan, then a horizontal wall, then another small vertical wall, then horizontal, etc...after 3 of these NO light can pass thru, make sure is flat black foam board... (make sure the fan is pointed in the right direction)...it sounds very diy but this stupid little light box can be made around any cfm, any size square shaped fan in theory....mine are 110 cfm and relatively quiet and transfer alot of air, hope this helps... heres some pics of what they look like...(in these pics i know their are ducts attached but this was a recent change and the original idea has no back face board, its just open, ive added ducts cause i had to cool my hood DIY style and also i got better exhause from the big silver ducting rather than just an open end...)

true, pvc elbows are a good way to go, lol, i made this cabinet as a first grow cabinet and it worked so i kept it goin, although a pvc elbow would have to be 3??...4 inches???im a plumber and i didnt even think of that...lol, oh well, these work good for now...its more of a fun little hobby grow and its whisper quiet...hats off, i agree PVC might be better in this application
