Didn't you just add a Phoenix 14000K? The peak spectrum of the phoenix is 450nm, and the peak spectrum of the royal blues is 450nm. So, it really isn't much for supplementation. Or am I thinking of someone else?

If you want to supplement a phoenix, go with 420nm LEDs, or maybe a mix of 420s and CREE blue (not royal blue), as the Phoenix lacks more in these areas.
