Starting from two parcels (1 and 2), separated by an intermediate aisle (3) and preferably equal to each other, a plurality of cultivation lines (4) is established in each one of them, and consist of conduits for the circulation of the nutrient solution for the plants and further acting as physical support therefor, a frontal planting area (5) being defined in the first parcel (1) with workstations for several operators (6), wherefrom the aforementioned cultivation lines (4) are moved to the opposite end of the parcel, to transfer them one-by-one from said rear end of the parcel (1) to the parcel (2), where they move in the opposite direction to the harvesting area (11), also established at the front end of the parcel (2). Therefore, a 300% increase in the planting density is achieved and the number of cycles per year is practically doubled, while a drastic reduction in labour force is also achieved.
