I like Panda film the best..It is Black on one side, white on the other. I can't stand the sound of mylar blowing around! Don't use Foil! Just like Pac Man say's, it will make hot spots, and burn your plants...GL
Yeah man, it feels like I just stepped out of a rave sometimes after being slammed with 2400w of HPS, and of course I play some trance while I am in the office...
