Light Blocked air vent

Hey Folks, I have a veg rm and flower room next to each other. I would like to draw the air from the veg room into the flower rm where I have a 4in fan and filter. How can I make a light proof vent 6x8 or so that is light proof but with good flow. Cue McGuyver music.....

bump, no ideas?

Light doesn't like to bend around corners so putting a couple of 90's in the line will help for sure JAS

Just cant get a picture in my mind, I can get crafty with cardbrd

90 degree elbow painted flat black inside should block out light with ease

google up light trap and get those juices flowin

I have a 3.5 inch axial fan with 4" ducting and a 6" intake with 6" ducting bent in an "S" configuration to keep my veg cabinet light from messing up the flowering room. I am in a closet and have my veg and flower in the same room.


Hope this helps.

Peace and Great Grows

guess I could also add that I have some black plastic strategically stapled to the side of my veg cab and it blocks the light not completely but enough to not bother my flowering plant 3 feet away from it
