Abstract: The object of the invention is to provide a process and a device for hydroponic raising of plants in a vegetal vessel filled up with a substrate, by conveying a nutrient solution into the roots feeding zone, wherein the supply of the nutrient solution is carried out by way of aerosol irrigation of the substrate surface at time intervals and with the periodicity and duration of irrigation depending on ambient air temperature. The device for the implementation of the process comprises a collector of the nutrient solution, a pump, a vegetal vessel with a drain connection, the upper portion of which accommodates a distributor of the nutrient solution made in the form of a tube which lower part is perforated, the said tube being placed at a distance above the substrate surface, the total area of the openings in the distributor tube is smaller than the cross-sectional area of the drain connection.
