Abstract: FIELD: agriculture. 
     SUBSTANCE: group of inventions relates to hydroponics and plant growing. System comprises: a) a plurality of stationary light supports, each of which is adapted to illumination of a predetermined room sector, in accordance with a predetermined light signature, wherein illumination signature of one or more light supports imitates conditions of noon light, morning or daylight; b) multiple towers for growing plants, which are exposed to light generated at any moment in time, and which are combined in at least one module, which determines darkened inner area of module, by means of which plants receive a sense of night time; c) plurality of light elements mounted on each of the light supports, wherein each of the light elements is equipped with a lens with a directed action, configured to create a light emission angle, the angular boundaries of which fall on the periphery of one or two towers, causing blocking of propagation of emitted light into inner area of module located between two adjacent towers, as a result of its falling on periphery of turret, d) a drive unit configured to cyclically rotate each of the towers about a vertical axis with a full turn of the turret once in each 24-hour period so as to be successively exposed to morning light conditions, midday light, daylight and night light, in accordance with the light emitted by the light supports signature of at least one module; and e) an irrigation device for supplying plants, cultivated on each turret, with nutrient solution. Plant cultivation system in the room contains: a) a plant growing device; b) stationary light support; c) irrigation device, each segment of light elements has light elements arranged such that selective beams are mixed inside conical distribution angle to create density of photosynthetic photon flux on peripheral section of device, due to which mixed beam falls so that it stimulates photosynthesis in plants, wherein light elements on light support are modulated to stimulate improvement of metabolic processes of plants. Artificial pollination system comprises: a) a light support on which the air outlet nozzle is mounted; b) rotatable turret for growing plants, on which one or more pollenscots are installed; c) a sensor for detecting actual position of plants; d) air-receiving reservoir for compressed air storage; e) a pipe extending from the air receiving container and exchanging fluid with a nozzle; f) a control valve operatively connected to the pipe; g) a unit for controlling local air humidity near the turret for growing plants; as well as h) controller exchanging data with sensor, control valve and unit, controller provides: i. giving the command to the unit to reduce local moisture to a level of sufficient reduction of the adhesive properties of pollen; ii. command to open control valve when signal transmitted by sensor indicates that one of plants is at such distance from nozzle, which provides access to released pollen, so that pulsed supply of compressed air promoted release of pollen from its anther and that air pollen to be delivered to carpel of the same or nearby plant, was directed to plant; iii. response of the command to the unit to increase the level of local moisture after releasing pollen; closing the control valve at the end of the pollination cycle. 
     EFFECT: invention ensures sustainable production of safe agricultural products.
