To add to everything....

As of late, it is said that in veg of course they like 6500K, but supposedly they also like some of the other spectrum too (2700k). So, some people put in a mix of the lights in about 15%-30% between vegging and flowering. Meaning during veg, if you have 10 lights then 8 would be 6500K and 2 would be 2700K. An in flower vice-versa. You don't necessarily have to go with that percentile, you can add one or two more, or just put in one. It's all up to you really. I still use the all 6500K for veg and 2700K for flower.

Either way, Good Luck and Happy Growing!
