Abstract: A soilless culture facility includes a frame supporting a plurality of profile sections extending parallel to each other in a horizontal plane, from a transverse loading area to a transverse harvesting area, and a plurality of supports, each suitable for receiving a culture substrate. The plurality of supports are longitudinally movable in the longitudinal gap defined by two adjacent profile sections. The movable supports are moved by a motor means suitable for modifying the distance between two consecutive supports during travel in the gap. The plurality of profile sections have opaque and flexible longitudinal joining side band strips, the joining side band strips of two adjacent profile sections joining to close the gap defined by the adjacent profile sections. The movable supports have arcuate slots in the front and rear cross-sections of same, to either side of a longitudinal vertical plane, the two band strips joining at the lower edge.

Abstract: The disclosure relates to an aeroponic culture line comprising a surface for separating the follicular space and radicular space, provided with openings for receiving porous culture supports and spray means arranged on the radicular side of the surface. The spray means are designed to produce a spray area that is smaller than 10% of the total area of the separation surface, the spray means being mounted on a carriage that can move in parallel to the separation surface, on the radicular side, in order to periodically cover all of the area of the surface provided with culture supports.
