Thanks for the link, I've read that a few times. I know it's almost shocking, but some folks actually do a lot of searching before they post, lol.
I've always wondered if people just use 6500/6700K bulbs with them simply because of that old myth that you needed that Kelvin rating for growth. It seemed to me that 10,000K would cut the purple/pink a bit better, but I suppose I'll just go "middle ground" and keep my dual daylights.
