I thought the spectrum promoting flowering vs. growth was debunked (or the 
effect was found to be marginal) years ago.  In any case, I usually get 
bulbs that look good to the viewer as opposed to the plants; I prefer 
6500K, which is cloest-looking to natural sunlight, and if I can't get 
6500K, I get 5000K.
