a 1x96w PCF would be v.good
a 2x39w T5-HO would be better
but with this much light you would
need DIY Co2 and to leave it on
for no more than 8 hours per day,
but you could grow anything well.
400W MH least that.

No, just kidding. What kind of plants are you looking for? Carpet plants too? CO2?
With just a few plants, 2 watts per gallon is a good ballpark.
