If its any consolation, the Inda-Gro thread gets bumped almost daily by Spliff as he posts progress of his various grows.
I'm considering induction for a future grow, but not Inda-Gro (too expensive). I have found a domestic source of induction lamps at various color temps and am thinking about 6500k for veg at least to replace my MH setup. I like the results of 6500k PLLs, just can't fit them properly into my latest veg closet. I could fit a 150 - 200w induction in there rather nicely and it should give me as good as if not better results than my prior PLL setup with less heat than my present MH.
