Hi Glennorch,
I'm sorry, i didn't have any notification for this PM, and i discovered it today.
I hope it's not too late.
You can use 3NW(4000-5000K)/2red/2red660, or 1RB/2WW/2R/2R660, both works well. But all strains don't react in the same way to a led spectrum, it is related if you are searching for yield or quality/potency.
Some strains prefers 660, other strains 625, some grows leafy buds when there is blue in the spectrum. But keep in mind that leds efficiency is more important than spectrum.
