Light proof intake vent help

I just finished putting together a corner in my basement to flower one of my plants. To save money for now its just a 5x5x8 area made from 2x2s and double layer 3 mil black plastic walls. I have a inline fan with carbon filter inside that I vented the exhaust through one of the walls for air exchange/odor control. I am looking for ideas for a light proof intake vent. This area is basically air/light tight right now and I have to leave the door ajar to provide air for the fan else it looks like its gonna suck the plastic off the 2x2s!
Any ideas?
 
take a short piece of pvc, two 90 degree elbows, and a can of flat black spray paint. spray the inside of both elbows with the flat black paint, allow to dry, then put the pipe through your vent hole and put an elbow on either side, both facing down.
that may not be 100% light proof, but pretty damn close, and it's cheap
 
Thanks for the replies. I'll have to google some of them. Im not sure what a baffle box and a dust shroom are.
 
Very nice. I have plenty of scrap lumber laying around. I'll see if I can make something like this.
I like the pvc idea too but can only find it in 10' lengths. Since I have the scrap I'll give that a try first. Thanks.
 
Some sort of box made of a non reflective material that lines up with the vent and a downward opening, might want another sheet of non reflective material inside the box at an angle so it obstructs light but not air.

I used black flex duct with an S-bend on the last run.

Ducting light traps

I use 6" ducting for my coo tube reflector. I need to be able to have the lights come on after I am at work, I go to work at about 5:30 a.m. And I work a lot of OT and that keeps me out until past 5:30 pm. So, I am trying to think of a way to keep the light on and not overheat the tent while I...

My old trusty baffle. Aluminum angle iron stacked with double sided 3M tape, and spray painted black. You can double the pattern and create an "s or z" shape to kill light even more, but this design serves me well. Happy growing.
