I think your led count looks ok. You've got 30 "white" XML's which by themselves, could provide up to 300 watts and plenty of PAR for growing anything you want. The rest of the leds will also contribute to PAR, but won't need to be relied on for anything other than color rendition. I'm looking forward to the build
