Lighting System for Promoting the Rapid Maturation of Commercial Plants
First Claim
1. A method of providing light to a plant with a life cycle that includes a seedling growth period, a vegetative growth period and a flowering growth period, said method comprising the steps of:
- providing an array of LEDs that contain red LEDs, blue LEDs and white LEDs;
positioning said array above said plant, wherein said plant is illuminated by said array during said life cycle;
illuminating no red LEDs, at least some of said blue LEDs, and at least some of said white LEDs to produce a blue/white light with a higher intensity of blue light than white light throughout said seedling growing period;
illuminating no red LEDs, at least some of said white LEDs, and at least some of said blue LEDs to produce a white/blue light with a higher intensity of white light than blue light throughout said vegetative growth period; and
illuminating no blue LEDs, at least some of said white LEDs, and at least some of said red LEDs to produce a red/white light with a higher intensity of red light than white light throughout said flowering growth period.

Abstract
A system and method for providing light to a plant with a life cycle that includes a seedling growth period, a vegetative growth period, and a flowering growth period. Illumination to the plant is provided with an array of LEDs that contains red LEDs, blue LEDs and white LEDs. During the seedling growth period, no red LEDs are illuminated. Blue and white LEDs are lit, wherein the blue light is more intense than the white. During the vegetative growth period, white and blue LEDs are lit, wherein the white light is more intense than the white. During the flowering growth period, red and white LEDs are lit, wherein the red light is more intense than the white light. The change in coloring and intensity has beneficial effects during each growth period and at the same time inhibits insects.
