The conclusion that just 660nm and 450nm leds is needed is very outdated check out pretty much any thread In the led section and you'll see that You need full spectrum leds generally people stick to around 3500k to get the plants to there full potential it's not just the chlorophyll a and b peaks you want to hit there's a lot more too it that that, like the upper canopy absorbing more red while the green penetrates the canopy better, this is why everyone these days is opting for using cxb3070/3590 leds
