CONTROLLED ENVIRONMENT AGRICULTURE FACILITY AND METHOD FOR ITS OPERATION

摘要

A controlled environment agriculture system is provided in which a plurality of plant grow support racks is arranged in an array complementary to an array of lamps which provide illumination for the grow racks. Two positions are provided for the rack array, so that in each position alternate racks are fully illuminated and the remaining racks are in relative darkness. The lamps can 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. An arrangement is included 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 air conditions to balance the rate of moisture addition through plant transpiration.
