Based on the example of an automated module of a vertical farm for growing plants, an author’s method for developing automated devices using modern microcontrollers and a high-level microPython programming language is proposed. Additive technology as a method of “rapid prototyping” made it possible to effectively solve the issue of creating the main components of the module. The works on designing, assembling, and adjusting the experimental setup were carried out using modern methods and approaches for the industrial development of devices. The automated system makes it possible to solve the problems of lack and selection of the correct dosage of nutrients necessary for plants, controls, and minimizes water consumption, the root system develops fully. These factors make it possible to grow an adult plant in a short time without human participation. The apparatus can be used for organizing research activities in the subject areas of the natural science cycle, for greening in corridors and classrooms, and growing fresh herbs.
