Method and apparatus for optimized plant growth
A system for enabling controlled plant growth of plants in containers includes linear tracks spaced apart from each other by intervening supporting plates. Each track includes an array of blue and red LEDs affixed to heat sink that can slide along the track to be positioned in a desired arrangement to the container beneath it. A controller for the LEDs is positioned between every other pair of tracks to control adjacent arrays of LEDs. The controller controls the LEDs to provide light to the plants in the containers of desired intensity and wavelength.
