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.
