Said culture is performed in culture containers (5, 80) either on movable and extensible substrates of granulates (100) or on wire networks (81). The plants are movable and spaced from each other by increasing intervals in all directions, either by the displacement of the granulates or by the pressure of blades or rods (90) carried by carriages (92) causing the sliding thereof on the wires. The culture may be performed continuously throughout the year. Cross beams (23-23bis) provided with baskets (27) enable to perform all ways of cultivation at all locations in the containers without requiring circulation areas. The containers (5) may be arranged above variable volume tanks (110), having substantially an equal surface, and containing a mixture of granulates and nutrient solution which may be stirred, homogenized and forced through nozzles (4) up into the containers (5), causing the displacement and the extension of the substrate. The medium may be readily sterilized in situ, the calories in excess may be recovered and the containers may be automatically cleaned. The containers (5, 80) may be piled in the form of "towers". The utilization coefficient of the light energy is close to one. The automation may be widely extended. Said method may be used for spatial culture. |
