Hey InsaneMJ, have you checked out the new line of Philips CDM lamps (ceramic discharge metal halide), they have an 860W CDM lamp that runs on a 1000W MH mag ballast, there vertical burn only so you could hang one right in the middle of your stadium, the full spectrum mixed with your other HPS lamps will cause a growth explosion, other than hydro this is the only thing your setup is missing IMHO, you should really check em out, they run from 145W to 860W, just humor me and get one and I guarantee you won't regret it:
