There are plenty of threads on here in regards to using led lighting. Just use the search function.

I can tell you that with the right led system you can grow what ever you would like. I plan on running 2 of these - http://www.evolutionledlight.com/ - on my 120 to start with and might up it to 3 later. I know there are several people either running them or planning to. Names that pop in my head are txg8gxp, ramsey, neogenix, ismvel.
