1. A lighting device for a plant, comprising:
a first set of radiation sources configured to irradiate the plant with visible radiation, wherein the first set of radiation sources includes a subset of blue light sources configured to emit blue light having wavelengths between 430 nanometers (nm) and 485 nm and a subset of red light sources configured to emit red light having wavelengths between 620 nm and 700 nm;
a second set of radiation sources configured to irradiate the plant with radiation having a wavelength greater than 700 nanometers (nm); and
a controller configured to control irradiation of the plant by the first set of radiation sources and the second set of radiation sources according to a plurality of predetermined irradiation parameters for the plant, wherein an intensity of the light irradiated from the second set of radiation sources is less than an intensity of blue light emitted by the first set of radiation sources, and wherein the intensity of blue light is less than an intensity of red light emitted by first set of radiation sources.
