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:
