Was just wondering if one 6" 90 degree PVC elbow would be enough to keep light from coming into my grow cabinet or would I need 2? Would like to use only 1 if possible?

Post a picture of what? We should all know what a PVC elbow looks like? Thanks for the reply though? Can anyone else confirm that one elbow is enough to trap the light out of my grow cabinet. Thanks for the help.

My only concern is space. I am building in a cabinet and have not a lot of room for 90degree pvc's to be going everywhere. Will one 90 degree work with an extension that goes straight up with maybe a black pantyhose like material over the top to help keep dust out work? I thought light doesn't bend around corners and a 90 is definately a corner. Please let me know. I will go with a different option if need be but rather use only one if at all possible. Thanks again for the help.

spray paint the inside of it black so light doesn't reflect around inside of it. I would suggest a J tube. Basically a U with one end shorter than the other... works great for me. $1.50 at home depot.

Is a j tube PVC or metal? How would I mount that so my cabinet stays stealth? Trying to picture it in my head but can't seem too.
