The heavier the reflective material, the longer it will last before scratches, folds, bends and tears, render it useless.

If you measure the distance from the bulb to the wall (or the mylar if that's what you use) and add that to the distance from the wall (the mylar) to the plant...the total distance is beyond the range of fluoro tubes or mini CFL's.

In other words...if you are not using HID lighting, (MH or HPS, or Mega-CFL's) you are basically wasting your money on something reflective, that won't do any good. :jointsmile:
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
