Process for the industrial cultivation, growing, harvesting, washing, packaging, labeling and cold storage of plants, in particular of salads, vegetables or field crops, characterized in that within a building a) plant containers of uniform size are mechanically filled with prepared humus in a separate humus room, b) the plant containers are conveyed to a separate sowing and planting room, where seedlings or seedlings are planted in the humus of these plant containers by an automatic robot or manually, c) the plants are subsequently cultivated in these plant containers in a separate cultivation room, by placing the plant containers inside the building on at least one floor (A, B, C) in a plurality of adjacent rows on conveyor means along a path through the building over a biological cultivation period, being misted with water as necessary and illuminated and heated by artificial light, the plant containers being irradiated day and night with the necessary artificial light by installing light sources between sprinkler nozzles with suitable LEDs with high luminous efficiency, for emitting light with a frequency spectrum similar to that of the natural sun, and whereby these LEDs are dimmable and thus the desired light intensity for the day and night situation is simulated per planting area, further according to the moisture requirement continuously determined by sensors in the humus the plants are misted with the water from sprinkler nozzles and by means of the heat from heaters above or below the plant containers in the cultivation space, a predetermined temperature for plant growth is maintained, and d) that the plants are harvested in a separate harvesting room outside the cultivation room mechanically by an automatic machine or manually, then washed in a washing plant in a separate washing and drying room and thereafter dried, and then packed and labeled in a separate packing and picking room mechanically by automatic machines or manually, and if necessary temporarily stored in an associated cooling room or directly delivered. a) plant containers of uniform size are mechanically filled with prepared humus in a separate humus room, b) the plant containers are conveyed to a separate sowing and planting room, where seedlings or seedlings are planted in the humus of these plant containers by an automatic robot or manually, c) the plants are subsequently cultivated in these plant containers in a separate cultivation room, by placing the plant containers inside the building on at least one floor (A, B, C) in a plurality of adjacent rows on conveyor means along a path through the building over a biological cultivation period, being misted with water as necessary and illuminated and heated by artificial light, the plant containers being irradiated day and night with the necessary artificial light by installing light sources between sprinkler nozzles with suitable LEDs with high luminous efficiency, for emitting light with a frequency spectrum similar to that of the natural sun, and whereby these LEDs are dimmable and thus the desired light intensity for the day and night situation is simulated per planting area, further according to the moisture requirement continuously determined by sensors in the humus the plants are misted with the water from sprinkler nozzles and by means of the heat from heaters above or below the plant containers in the cultivation space, a predetermined temperature for plant growth is maintained, and d) that the plants are harvested in a separate harvesting room outside the cultivation room mechanically by an automatic machine or manually, then washed in a washing plant in a separate washing and drying room and thereafter dried, and then packed and labeled in a separate packing and picking room mechanically by automatic machines or manually, and if necessary temporarily stored in an associated cooling room or directly delivered.
