cool i thought it might be something like that. i have a blackdog 360 in my veg tent(just got it) and 700 in my flower tent. i couldnt see the greens at first but i could see it when the light would reflect off something.
havent gotten to see them really do their stuff yet since i have had va bunch of soil and ph problems but i think i have that all ironed out so we'll see. i have friend who has a few also and they work killer for him.
