thanks for that input. I am really digging the 100 watters so far. but for flower/bud where do you recommend to buy?

also did you see the inda-gro lamp life schedule that puts these lamps at 100,000 running hours?
Inda-GRO
it's at the bottom of the link. compared to the other lamps they show that's unheard of. whadya think? Can any lamp run tbat long and keep up the light?

After seeing it I'll say one thing that really jumped out at me was the metal halide falls off lumen output pretty fast. For me that probably explains some of my earlier grows veg irregularities.

thanks
