When I read this thread on Saturday, I started to become worried by the turn it was taking, but was relieved to see apologies being proferred. Then I was warned that it was geting somewhat out of hand again, and I have to agree. Unless someone has something else to say which directly answer's the OP's question, I think it's best that the thread ends where it is.
Getting back to the OP, at work I have to optimize indoor plant growth conditions, and one conclusion I've drawn so far, is that whatever the spectrum or output of LEDs provided, plants will grow and flower. They may not grow at the same rate, or the same way, but for supplemental light sources, I don't think 3000K or 5000K would matter much. It's supplemental and not the sole light source. I also bought LEDs for supplemental winter lighting at home, and also chose the higher K because it's nicer to look at. After 1.5 winters of use, I see improvements in my plants, which I attribute to any sort of supplemental light being better than none at all, rather than the specific spectrum.
