Hey everybody,if anybody needs to make a light proof vent heres one that I build and have two of them in my flowering closet door.I used 1/8" lauan plywood.Its cheap cost.I did a big one in my cab with a fan to bring in freash air.You can even make it out of card broad too. PEACE

Hey GN ,no wind noise.You know when the light go off.The closet is ac from the central unit. and two fans blowing all the time.When the light is on the 200cfm exhaust fan pulls air from the closet so fresh air comes in the vents.when the lights go off the light fan go off to.Just the two fans blowing and the ac.And that's when you can smell them.The vent is exhausting out of the closet from the top vent and comes in the bottom vent.I just work on it and got lucky and got it right and its working for me.It will exchange air with or without the fans.But no dark room dose that and works for plants too. PEACE

I used one of these back in the day when I actually had a darkroom. The principal is certainly transferable.

That's where I learn about them. see store make dark room vents on some sites and the cost is out of this world,for something that is this simple. Peace

If someone feels not up to building one of these, which work great BTW, here is an easy alternative. Cut the hole for your interior intake vent near the baseboard level. On the exterior side, and assuming a hollow stud wall, cut the exterior hole at about chest level. If there is still some small leakage of light, and there likely will be, buy some of that black filter material that is used to refill stove vent filters (available at H Despot). Use it double thickness on the inside of the interior vent cover. It will not impede flow but eliminates light and even provides some filtering of outside dust particles.

Getahead that's a great idea,all you would have to do is save the picse you cut out and when or if you move it easy to patch back in.my closet has a bi-fold door.I just removed the door leaving the door track in place and framed in the door opening with plywood.That's why I use the dark room vents.But I do like your idea alot. PEACE
