METHOD FOR HYDROPONIC GROWING OF C PLANTS Russian patent published in 2006 - IPC A01G31/00 A01G9/18 

FIELD: agriculture, in particular, growing of plants in protected ground, for example in greenhouses, on neutral substrate with feeding of plants with macro- and micro elements supplied to zone under roots and feeding with carbon dioxide.

SUBSTANCE: method involves growing C₃ plants in greenhouses on substrates by feeding nutritive solution under plant roots, feeding of plants with carbon dioxide and also by providing illumination with the use of lamps; hermetically covering plants with transparent film laid over constructions which may be adjusted in vertical plane as plants grow. Carbon dioxide is automatically supplied to zone under film by means of programmer. Nutritive solution is supplied into substrate in accordance with signal generated by moisture content sensor.

EFFECT: reduced consumption of carbon dioxide supplied for feeding of plants, decreased capital and operation costs, reduced consumption of power for heating greenhouses, and increased yield of plants.
