Abstract: A method and apparatus for growing plants using artificial light wherein pulsed fluorescent lamps are placed among the plants themselves below the plant tops and are pulsed on and off at a rate such that the plant can utilize the light photons in a chemically useful way with regard to that rate which maintains the lamp bulb temperature below a level that would be harmful to the plants. This technique significantly enhances growth and enables the lamps to be used as a supplemental lighting system in combination with natural light. To increase the life and overall yield of the plants an arrangement is also provided which includes a compartment containing a nutrient solution and a movable belt or the like to which the roots of a plant attach.
