Abstract: The invention relates to the field of soil and ionitoponic (ionitoponics) automated cultivation of plants having various morphological structures and can be applied in everyday life. The technical result to be achieved by the invention is to ensure a balanced growth and development of plants without human intervention. The essence of the invention is that a plant cultivation device comprises a plant cultivation chamber and the following controller-operated modules: a lighting module, a ventilation module, a substrate humidity monitoring module, an irrigation module, a module for monitoring a water level in a reservoir, and a plant growth stage monitoring module. The device further comprises: a controller-operated plant cultivation module comprising a container and a substrate provided with all necessary micro—, macroelements and microorganisms to achieve the best plant growth; a substrate humidity monitoring module; and a means for differentiating air flows.
