T5 light set up

Hi I have a fixture that will be holding 6 t5 light bulbs. They are eiko's f54t5/ho/841. They put out 54 watts a piece i believe. The whole fixture putting out 316 watts. How many plants could I grow under this setup. I have 2 Coralife fish tank aquarium and plant fixtures that are 24 inches each that i might supplement with this. Would this be enough for about 4-5 small indica plants.

I and growing 6 plants with 2 36" 4 bulb HO T5 aquarium lights on top, 1 24" 4 bulb HO T5 aquarium light on one side, 1 48" 2 bulb T8 shop light and 1 36" single T5 on the other side, 2 24" HO T5 on one end and some CFLs mixed in. This is working very well for me, in week 6 of flower and I have nice large buds. IME side lights helps a ton with T5. Yep it will work out nicely. Your pics are really small BTW.
