A conception of a highly productive method and an automated agritechnology have been proposed, which allow to grow improved plants in a completely controlled way under adjustable conditions, the plants being further adapted to the real conditions of growth. The implementation of the conception provides for integration of the modern methods of growing plants (aero- and hydroponics, climatic chambers, phytotrons, as well as a culture of isolated cells and tissues in vitro, and selection of modes and parameters of growing for a specific vegetal culture and a variety thereof. The goal of the research has become the assessment of the factors of growing cultural plants under the conditions of controlled parameters of the microclimate inside a closed artificial ecosystem, which is implemented by means of the automatic agritechnology proposed. The most significant factors, which are selected as a result of the researches shall be used for further planning of the experiment. The solutions proposed allow to not only effectively obtain the all-season output of crop products, but also seed and planting material. Also, the agritechnology proposed shall allow to produce products under the conception of vertical city-farms, which makes it independent from the area and time of growing.
