Hey Ponic glad to see you here :thumbsup:
As for feeds there are plenty of them out there but I stick with GH 3-Part. The main reason why is it is all I have ever used and does just what I want so it's good enough for me hehe. As for lights I will google your system so I can see what it looks like but couple things to think of ..........
From what I have read 600w lights are the most efficient but you have to run a conversion bulb if you want MH to veg with.
Cooling is key so kinda in a roundabout way what kind of cooling for these lights will you be using is almost more important than the lights themselves.

As for the kind of light there are some many combinations out there its nutz!! I do a lil reading and I'll get back to ya on that 1 :jointsmile:
