I love mylar....I use the 2 mil x 50ft for $30 (bought off ebay) I have 48ft to cover (4 - 12ft long walls)

I have been using the same mylar for about 4 years now...couple hints..use duct tape where you are going to mount the mylar to prevent tearing....dont let it get wet or have condensation on the mylar.... that dulls the reflectivity
VapedG13 Reviewed by VapedG13 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
