Light leak thru Booster fan HELP!

i have a two room set up one for veg growth in a tent under t5's and i just got everything last night for my bloom(flower) room which is a sealed 4x4x7' booth under 400w HPS my question is i will be drawing air with the booster from my veg room into my flower room and than out from there with a 6" centrifugal fan and a goblin scrubber i am worried about a light leak from the veg to the bloom room thru the venting and fan between the two rooms any suggestion on how to keep the light out of my bloom room when the veg is still on i know the littlest light will cause issues????

Try putting elbow on both sides? Or, a piece of short ducting on each side? Either, should help quite a bit, if not completely eliminating it.

You could also attach ducting and spray paint the inside of the ducting black to reduce the amount of light that reflects down the ducting into the room.

Also as Jawbrodt mentioned some elbows would also help to reduce the amount of light leakage.

They also sell ducting with a dark interior that does not reflect light.
