This is not true. 2300K, 3200K, 4100K, 5000K, 6500K, 7500K, 8000K, 10000K... I've grown lush plants with all of them. All you need is enough of the kind of light you are providing.

My personal preference is 4100K, smooth spectrum.

I'm not sure why this 6500K "rule" keeps being passed around. I'm guessing it's marketing.
