A greenhouse screen comprising strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product. The film material comprises a highly transparent, biaxially oriented, UV and flame-stable polyester film which is provided on at least one side with a coating which reduces the reflection of visible light. The greenhouse screen is particularly suited for the cultivation of plants with high light requirements.

There is a module for vertical farming. Vertical posts form a grid having rows in both the longitudinal direction and transverse direction. Diagonal support members are installed between posts in a longitudinal direction, along two opposed inner sides of the module, one being along a corridor for passage. In the transverse direction, other diagonal support members are installed without blocking the corridor, and racks are formed in said direction comprising the other diagonal support members, the racks extending vertically for growing plants therein along a height thereof. Floor anchors and corresponding ceiling anchors, located respectively at the bottom and at the top of each one of the posts, are provided to fasten modules on top of each other such that the structure formed by the posts is the load-bearing structure. Catwalks are installed for human passage in the corridor and between adjacent racks.

A ventilation system may include at least one air handler configured to supply an air flow to an enclosed grow zone and at least one heat pump coupled the at least one air handler and to at least one dry cooler. The at least one heat pump is operable in a first mode of operation in which a heat exchange fluid is cooled by the dry cooler and used to cool the air flow to remove moisture before the air handler supplies the air flow to the enclosed grow zone.

A solar module assembly includes a frame having an upper portion encompassing an area and a mid portion disposed below the upper portion. A plurality of solar panels is arranged in a string, sandwiched between two transparent panes forming a single string panel. The solar panels occupy less than the area of the upper portion. Each of the plurality of solar panels has a pair of opposing edges. A reflector is mounted on the mid portion to reflect light selectively.

A growing system is described where plants are grown in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit them at stations where goods may be picked out. The containers may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing means, data logging means, growing means, water and nutrients.

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.

A process for obtaining a material including a textured glass substrate coated, on at least one of its textured faces, with an antireflective coating of sol-gel type based on porous silica, includes a stage of application, to the at least one textured face of the substrate, of a solution containing at least one silica precursor and at least one pore-forming agent, then a heat treatment stage targeted at consolidating the antireflective coating. Before the application stage, the glass substrate is subjected to a preheating stage, so that the at least one textured face intended to be coated with the antireflective coating has a temperature within a range extending from 30° C. to 100° C. immediately before the application stage.

A plant cultivation device may include a cabinet forming a space in which plants are cultivated: a door connected to the cabinet to open and close the space; at least one bed disposed in the space; at least one light assembly that irradiates light onto the at least one bed; a tank configured to store a fluid; a fluid supply module configured to supply the fluid to the at least one bed; and a sterilizer positioned outside of the tank and configured to sterilize the fluid within the tank.
