FIELD: agriculture.SUBSTANCE: invention relates to the field of crop production. The device comprises a number of units equipped with laser devices, as well as the refrigerator, the power unit, the chambers of preparation of the nutrient solution and the gas mixture, the automated control system (ACS). And each laser device is located above the plants with the ability to supply the laser beam onto the floating mirror prism which reflects the beam alternately to reflecting mirrors located concentrically around the central vertical axis of the device, mounted coaxially with the central vertical axis of the laser device, which initiate the rotation of the leading sprout of the plant. The leading sprout is located in the capsule which is suspended under the watering-pot providing the plant with nutrient solution. Under the capsule the tray for collecting and draining the used solution is mounted. At that under the capsule with a plant on the sleeve supported on the tray the non-translucent wheel with openings is mounted, equipped with pins on the lower surface. And the sleeve is attached to a flexible two-layer plate comprising a photosensitive polymer material which, heated periodically from the laser beam directed from the rotating mirror, attached pivotally to the side edge of the tray obtained from a reflecting mirror attached to the ceiling, changing its height and hitting the ends of the pins, has the ability to bring the wheel into the rotational movement. The laser beam passed through the openings in the wheel, due to aspiration of the plant to light, pressing it against the capsule board provides its spiral shape. And every even mounting wheel is equipped with a training circle, acting with which on the central translucent disc located on the same level with the wheels and equipped with the identical training circle, is able to drive the rod into rotational movement, on which the disc is mounted, and which, located on the central vertical axis of the device, is
