My answer is partway between "who cares" and "no".

I've grown foliage type plants on nothing but the blue-spectrum CFL lights and they seemed perfectly happy and healthy to me. Redder light does help with flowering plants.

My attitude is go with what you want and can afford. With CFLs it's easy to try different configurations and just stick any bulbs you decide you don't like in the front porch light or something.

If all it grows is leaves, the 6500K bulbs are going to best promote that so I'd start out with those and maybe add some 2300K bulbs later if you want to see if it helps.
