1. A light source for growing a plant or a plant propagule, comprising:

  • a power component requiring an amount of input power;

    a light-emitting component receiving said input power from said power component for illuminating, for a period of time, a growth area of said plant or said plant propagule with an incident light having a spectral profile defined by a first set of wavelengths, a second set of wavelengths and a third set of wavelengths, said light-emitting component provides a photosynthetic productivity from said plant or plant propagule that is greater than that achieved if the same said growth area of said plant or said plant propagule had been illuminated by another incident light for substantially said period of time, and said another incident light includes said first set of wavelengths and third set of wavelengths, but does not include said second set of wavelengths; and

    wherein said first set of wavelengths includes wavelengths that are between about 400 nm and about 470 nm, said second set of wavelengths includes wavelengths that are between about 526 nm and about 570 nm, and said third set of wavelengths includes wavelengths that are between about 626 nm and about 700 nm.
