Upgrading to dual 250watt MH

[Emprr_Angl]

I'm about to get a dual 250watt ballast. My question is what would be a good light. I've missed the coolness of VHO's ever since I made the switch to 10k metal halides.

Right now I'm thinking about XM's or a 14k K...I hear Radiums have the coolnes but not the intensity.

Oh, i'm doing sps's so I want good growth as well as colour.

Any suggestions?
Thanks,
-Chris
