I still say, if you want to grow SPS and have it colour up nice, T5 lighting is the way to go! I know know the hydro bill would take a hit but there's no comparison IMO when it comes to growth and colour.
Saying that, I think T5 with some Royal Blue supplemental LED lighting is even better! Gives that extra pop and shimmer that T5's can't provide.
If money is no object on this build, the new ATI Hybrid fixtures with LED and T5 lighting look freakin awesome!!!!
