The Spec fixtures aren't strong enough for anything beyond lower light plants.

In order to grow a carpeting plant successfully (something other than moss), you'll also likely need DIY CO2 at a minimum. Flourish Comprehensive won't cut it and Excel likely won't give you the results you're expecting.
