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.
In your opinion, what are the 4 major photosynthetic peaks in the visible range?

If there is interest I would be looking for both testers and investors for the USA. Here are the pros of this new light: 1. Low Rating: 5
