I would look more at the different color bulbs, the KZ and ATI especially. A stock 10k and actinic aren't going to do much for "pop". I have 2 fixtures with bulbs like that and they're enough to grow things, but not to emphasize color. Look around for threads on T5 combos and you'll find lots of recommendations. I've bought coral from under a T5 that I've been disappointed with once home under the LEDs...
