So you've got 6x65w pc's and then a 175w halide?
You should be able to grow whatever softy you want right now, but personally i'd sell those pc's. You could easily get enough to buy either a second 175w halide (allowing you to grow pretty much whatever you want in that tank) or buy a decent t5 setup, which combined with the MH would have GREAT color, and you could grow just about everything...
