spectrum:380, 430, 450, 470, 630, 650, 660, 730, 10,000k
Each disc has 15 leds on it so what should the ratio be?

I was told for flowering this would be a good ratio.

1(380) : 1(430): 1(450) : 1(470) : 3(630) : 3(650) : 2(660) :2 (730) : 1(10,000k)

Been researching this stuff a lot... here's 2 different ratios that have a proven track record and are used by at least 2 LED companies.
6000k, Red & Deep Red 7:4:4
2 x 6500k , 1 x 430nm, 2 x 455nm (blues) : 9 red: (1 x 630nm, 4 x 640nm, 3 x 660nm): 1 infrared (730nm) 5:9:1

There's also some cats who think that a broad spectrum is more productive... so something like 12 x 4000k 3 x 2700k.. or maybe change out 2 of teh 4000k for 660nm
