T5 VHO!
You can grow anything under the VHO bulbs!!! The VHOs have more output wattage and last much longer (I've read, but not experienced 18 months). I have been seriously debating my lighting scheme and selling my 250w MH to switch over to a Aquactinics T5 VHO with the IceCap SLR reflectors. It's going to cost me alot on the frontside, but in the long run I should fare better in cost effiency in comparison to the three 250w Metal Halides that I have been pondering. www.zeovit.com Tons of pictures of T5 driven tanks... WOW.
