1. A grow-light comprising:
a first solid-state light source for generating blue light with a blue photon flux; and
a second solid-state light source for generating red light with a red photon flux;
wherein a ratio of the blue photon flux to red photon flux is from about 1:3 to about 3:1; and
wherein the first solid-state light source is for generating a first broadband blue light with a maximum emission intensity wavelength from 420 nm to 450 nm with a first blue photon flux, and a second broadband blue light with a maximum emission intensity wavelength from 460 nm to 470 nm with a second blue photon flux, and wherein a ratio of the first blue photon flux to the second blue photon flux is from about 2:1 to about 4:1.
