This disclosure is of a controlled environment agriculture system in which a plurality of plant grow support racks are arranged in an array complementary to that of the lamps which provide illumination for the grow racks, so as to provide two positions for the rack array in each of which positions alternate racks are fully illuminated and the others not. The lamps then may be operated continuously and the rack array shifted between these two positions to provide alternating periods of full illumination and relative darkness for each rack. Means also are provided for improving the uniformity of air distribution to all racks within the array, and for control of humidity within the system by adjustment of the rate of moisture removal by the air conditioners to balance that of moisture addition through plant transpiration.

A controlled environment agriculture facility comprising: (a) wall and floor means defining a plant growth enclosure within which a controlled atmosphere may be maintained; (b) an array of plant grow support racks disposed within said enclosure, each said rack being of rectangular configuration with width and length dimensions and including means mounting the rack for at least limited reciprocal movement along a line parallel to its width dimension, the racks being arrayed in proximity to each other with their length dimensions in parallel relation; (c) a plurality of lamps mounted in said enclosure above said racks and divided into groups with the lamps of each group disposed along a line parallel to the length dimension of the racks and with the lamp groups spaced along a line parallel to the width dimension of the racks, the number of such lamp groups being correlated to the number of support racks as a fractional multiple thereof; (d) said plant grow support rack array being movable back and forth between a first position in which alternating racks of said array are disposed in sufficiently direct proximity to a respective one of said lamp groups to be subjected thereby to relatively high intensity illumination and in which the other racks of said array are disposed more distantly from the most proximate of said lamp groups so as to be subjected thereby to substantially lower intensity illumination, and a second position in which the relative intensities of illumination of the racks of said array are reversed, thus enabling even distribution of illumination as between all the plant grow support racks by shifting the plant grow support rack array back and forth between its first and second positions.
