FIELD: agriculture, in particular, plant growing in protected ground constructions. SUBSTANCE: greenhouse has enclosure 1, plant growing system with hydroponic vegetative units 2 formed as prismatic carcasses 3 carrying troughs 4 with plants 5, plant radiation system with stationary radiation sources 6, and control unit 7. Plant radiation system has light intensity controlling units with light intensity sensors 9 and additional dosed radiation control units with auxiliary optical radiation sources 10 mounted for reciprocation along and transverse to surfaces of carcasses 3. Outputs of light intensity control unit and inputs of additional radiation unit are connected with metering inputs and control outputs of control unit 7. EFFECT: increased efficiency and simplified construction. 3 cl, 2 dwgc |
