Hi Angie. Are the inhabitants suffering from having the 192W PC light on it? Why not stick with that?

That being said, T5 are great. If you can swing a 4x54W setup, go that route. A 2x54W should be fine for lighting things up, more like a FO tank, but it may also be adequate for macro, but I don't have much experience in growing plants.

If you narrow your search down a bit, I can maybe get you a good deal through my store.

Later!
Eric
