Led Color Spretrums

are there any advantages to adding some Cyan, Green, Red/Orange, Uv to the normal White/RB combo?

I think the red and green phase is a passing fad. The right White/Blue/ Royal Blue combo performs and looks great. I can't see how one or two sparsely distributed red and/or gree LEDs will make a difference.

I agree with pat. The RBG thing is slowly loosening it zeal. I run 454uv blues along with my AI sol super blues. I haven't seen any real difference in growth to say , but it does bring a little more pop to the colors.I still think the greatest advantages to LEDs boil down to cost of running the system and heat control. The biggest thing when using LED'sis the bulb and optics choices and the ability to control each one to achieve a combo that will work and please your eye at the same time!
