Abstract: The system of the indention is applied to sunless enclosed spaces suitable for agricultural use. A growing zone is seeded with a particular crop variety. The crop growth is optimized by receipt of a specific light emissions. A light emitting computer comprising an array of light emitting devices, a microprocessor, a radio frequency receiver and a storage device is disposed optimally over the growing zone to bath the zone uniformly in the specific light emission for optimal growth. A radio frequency identification tag is placed within the growing zone to electrically define the growth zone for the light emitting computer. The RFID tags emit a crop variety specific radio frequency that is received by the radio frequency receiver. The appropriate light emission profile related to the radio frequency is retrieved from a digital look-up table. The emitting computer then emits the light emission profile.
