cant get rid of lite!

[Pezzo]

imagine a concrete or block shed, wiv a section built in it wiv black plastic on it. basically i built a grow room in my shed out of wood and attached it to the shed wall, put plastic in the center to seperate it...

veg room has 24/7 lite but i cant attach the plastic to the wall to seperate it from the flowerin room and nothing else will stic to the wall (like celotape) so i have a 1/2" gap and cant close it, any ideas?

Duck tape, spray insolation, a tarp, a strip of 2x4, pond liner and probably a few other things, but I am not sure exactly what the serface is that you are trying to seal up, the wall and the plastic, wood, or what.
Hope it works out.

hey thanx neva thought of them, surface is an unrenderd block wall so nothin sticks to it, would bodge tape? Only i dont have duck tape

[mattmao]

if its wood your attaching to tack the sheeting to it then cover the tack holes with mastic,if its a solid concrete wall silicone glue will do the job

ok i sorted that, got some glue stuff it worked gr8, but now thats sealed more holes are appearin which i neva sin b4 and i dunno how to make the door lightproof i have one idea is to velcro plastic on the outside that should work...
