Closing A Space Using Cloth Wall And Zipper

Anyone know where I can get a "One Size Fits All" sort of cloth wall to close my flower room up a bit smaller? I'll need to have a big zipper as this will be the entry to the S2 room also. Like the shit grow tents are made of, but I only need one wall's worth...

anyone know where I might get this?

right on thx. I'll search it. I'm deep in the Hawaiian jungle, it'll have to be online.

Just to verify with you guys, this stuff wiil black out, right? I mean, in the presence of lo light, pand film won't allow light to pass thru this wall, right?
