I'm with IR on this one. Plus, plastic sheeting can trap moisture between it and the wall. (mold)

Why not a white sheet hung with some push-pins? Does cotton-fiber white reflect less than wood-fiber white, or any more than cotton-polyester white? Is the difference worth worrying about?
Rusty Trichome Reviewed by Rusty Trichome on . mylar substitute? hello, i couldn't find mylar anywhere and i can't paint the walls of my growcloset, so instead I bout this shiny metallic silver paper at an arts and crafts store. Was this a waste of money? should I even hang it up? and for some reason I feel like if i use this paper im gonna start a fire or something, has anybody else used metallic paper like this? also is there anything else i could use for the walls besides mylar and white paint Rating: 5
