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. As the plant grows and extends in length, the stem of the plant is pulled down into the nutrient solution to provide root growth area which permits the previously adventitious roots to develop as new roots on the newly submerged stem so as to maintain more optimum spacing between the plant roots and the aerial extremities of the plant, hence minimizing translocation distances that minerals and plant compounds must travel for new growth.
