I'm about to revamp my grow room, and I was wondering, right now I have foil on all the walls, and I feel like it is better to have something that is a flat white, but the walls are crumbling. If I stick poster board to the wall will that work? you know, those big square sheets you get at the grocery store for like 89 cents a piece. If you think they will work, which side should i have facing out? the shiny side or the dull/ flat side. Any suggestions would be great. Thanks. Look out: White Widow and Purple Haze coming soon
Hmm.. i'm not sure, mylars supposed to be hard to work with, and i'm allready pretty over budget on this thing
I dunno what your talking about, but if you paint it white and no light can leak through it you will be fine.
