Both panels you guys have shown will work but not really produce. Poor ratio of red:blue, poor choice of wavelengths in some cases. Total waste using the white diodes. Having now run tests between my tri-band and my prototype quad band with white, the tri-band is performing the same.

There's only 4 major photosynthetic peaks in the visible range, and the 5th carotenoid/phycoerythrin/phycocyanin 'peak' is primarily applicable to aquatic plants like algae and kelp and pond lilies instead of terrestrial plants like cannabis.

UV isn't necessary - just an overdose of blue light in the right wavelength achieves the same results. IR can help but really it's a complimentary spectrum that must be accompanied by another wavelength to create the Emerson effect.
