1. A method of enhancing plant growth steps comprising:
- producing, with at least one lighting element, a light output at a wavelength that is within 20 nm of a peak absorption wavelength of a predetermined pigment of a plant;
positioning the lighting element adjacent to the plant such that the light output produced is received by the plant; and
modulating the light output to create predetermined periods of light and dark for the predetermined pigment of the plant to enhance growth of the plant;
wherein the light output is modulated by providing an AC input having a frequency of 60 Hz or less.

Abstract
A method of stimulating plant growth in a controlled environment that includes providing a lighting assembly having a network of lighting elements such as light emitting diodes (LEDs) that provide light at a color tailored for an individual plant. The lighting assembly is positioned adjacent a plant such that the light produced is received by the plant. The lighting assembly additionally has a control assembly that includes driving circuitry that modulates the lighting elements to controllably provide predetermined periods of light and dark to stimulate continuous growth of the plant.
