Multiple colors, and color palettes, of narrowband photosynthetically active radiation (PAR) time-staged over hours, days, and growing seasons yields superior plant growth

A method of providing artificial PAR to a plant for growing, the method comprising:

• independently delivering diurnally at and during at least three different flux levels at least three different spectra of PAR drawn from the group consisting of
• 1) a spectra called “ultraviolet” containing light in a narrow band of wavelengths not broader than 70 nanometers Full Width Half Maximum (FWHM), and including light of 385 nanometers which affects early light-inducible protein,
• 2) a spectra called “ultra blue” containing light in a narrow band of wavelengths not broader than 75 nanometers Full Width Half Maximum (FWHM), and including light of 420 and 439 nanometers which affects chlorophyll A, alpha carotene, and carotenoids,
• 3) a spectra called “aqua blue” containing light in a narrow band of wavelengths not broader than 70 nanometers Full Width Half Maximum (FWHM), and including light of 430 and 475 nanometers which affects chlorophyll B, beta carotene, and carotenoids,
• 4) a spectra called “green” containing light in a narrow band of wavelengths not broader than 50 nanometers Full Width Half Maximum (FWHM), and including light of 525 nanometers which affects CO2 fixation and intermodal distance,
• 5) a spectra called “gold orange” containing light in a narrow band of wavelengths not broader than 95 nanometers Full Width Half Maximum (FWHM), and including light of 590 and 625 nanometers which affects phycoerythrin and phycocyanin,
• 6) a spectra called “red” containing light in a narrow band of wavelengths not broader than 60 nanometers Full Width Half Maximum (FWHM) and including light of 645 nanometers which affects chlorophyll B, chlorophyll C, and allophycocyanin,
• 7) a spectra called “ultra red” containing light in a narrow band of wavelengths not broader than 50 nanometers Full Width Half Maximum (FWHM), and including light of 667 nanometers which affects chlorophyll A and phytochrome, and
• 8) a spectra called “far red” containing light in a narrow band of wavelengths not broader than 50 nanometers Full Width Half Maximum (FWHM), and including light of 735 nanometers which affects chlorophyll D and phytochrome.

A lighting system for producing photosynthetically active radiation (“PAR”) comprising:

• multiple pluralities of narrowband light emitters, each one of the plurality of emitters emitting light at a plurality of wavelengths associated with the individual emitters that are within the plurality;
• and
• a multiplicity of power sources each for controllably energizing an associated one or ones of the multiple pluralities of narrowband light emitters;
• a time-of-day clock;
• and
• a computer responsive to the clock for controlling the multiplicity of power sources so that each does energize an associated one or ones of the multiple pluralities of narrowband light sources upon a diurnal basis, and does cause the narrowband light sources of that plurality to emit colored lights, making that a composite PAR is generated over the course of a day wherein the colors do change over time in response to the time-of-day clock.
