I bought a big roll of that blackout reflecting surface fabric stuff (same stuff they use to make the expensive grow tents). anyways i want to know iif anyone has used this stuff and so what did you use to lightproof the holes you made for you ducting???...i tried black duct tape it fell off. Then i bought some extra strength more expensive guerrella tape and that fell of too after about a week. any ideas or feed back appreciated
