Abstract: The invention concerns a foldable greenhouse screen (2) comprising strips (11) of film material that are interconnected by a yarn system of threads (12) by means of knitting, warp-knitting or weaving process to form a continuous product, at least some of said strips (11) comprising a substrate (061) covered with a stack of thin films (063) on a first side of the substrate, so that said greenhouse screen has: a transparency coefficient of at least 40% but no more than 80% in the range of solar radiations, and a reflection coefficient higher than 70% in the middle infrared.

Abstract: A foldable screen for a greenhouse is described. A foldable filter for greenhouse, comprises a foldable substrate and at least one stack of films on the foldable substrate, wherein said at least one stack of films is adapted to —reflect solar infrared radiations in the spectral range from 850 nm to 2,000 nm, and —be transparent to solar radiations in the spectral range from 400 nm to 750 nm, wherein said at least one stack of film comprises: —a first layer of TiO2, ZTO, Si3N4 or NbOx; —a second layer of Ag on top of the first layer, and —a third layer of dielectric on top of the second layer.

Abstract: A screen for greenhouse or for outdoor cultivations is described. A foldable screen for greenhouse or for outdoor cultivations, comprising: a canvas, a substrate on one side of the canvas, arranged for preventing convective heat transfer through the screen; at least one stack of films mounted on or adhering to said substrate, wherein said stack of film is adapted to:—transmit at least 80% of radiations within the range from 400 nm to 2,000 nm when said radiations hit said film at normal incidence,—reject at least 70%, preferably at least 80% of radiations at normal incidence within the range from 3,000 nm to 35,000 nm.

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.
