The present invention relates to a coated polyester film equipped on at least one side with permanent antifog coating. The film of the invention is suitable for the production of greenhouse blinds, and has specific transparency properties, permanent antifog properties and high UV resistance. The invention further relates to processes for the production of the polyester film of the invention, and also to use thereof.

Automated terrariums and methods of using the terrariums are disclosed. The automated terrarium comprises a housing having a base and a lid, wherein the lid is supported by at least two support pillars. The terrarium also comprises at least two transparent side panels supported by the at least two support pillars and positioned between the base and the lid, an irrigation system within the base, a lighting system within the lid, and a control unit. The control unit is adapted to monitor growth of the plant and adjust the irrigation system, heating system, airflow system, and/or lighting system.

A light-deprivation system includes shades having a fixed end that form a perimeter that defines a growing environment, cables attached to a free end of each shade, a cable guide located near a pinnacle of the light-deprivation system, and a winch to draw the shades. The cables run from the free end of each shade, through the cable guide, to the winch. Operation of the winch draws the shades simultaneously to block substantially all light from sources external to the growing environment from reaching the growing environment.

The present invention relates to greenhouse screens comprising strips of film material that are interconnected by a yarn system of longitudinal threads and transverse threads by means of a knitting, warp-knitting or weaving process to form a continuous product. At least 50% of the strips comprise a single- or multi-layer polyester film having a transparency of at least 92%, wherein the polyester film has a first and a second surface, wherein a permanent antifog coating has been applied to at least one of the first or second surfaces of the polyester film. The antifog coating comprises at least one water-soluble polymer, an inorganic hydrophilic material and a crosslinker, wherein the water-soluble polymer is a polyvinyl alcohol or a hydrophilic amorphous copolymer. Furthermore, the present disclosure relates to production processes of the coated polyester film and its use for the production of energy-saving screens having excellent antifogging effect in greenhouses.

The agricultural greenhouse of the invention and the plant cultivation method using the same can cultivate plants economically and efficiently with less energy per crop yield, as it is provided with a CO.sub.2 supply means, a heat-ray shielding means, and a dehumidification and cooling means, the heat-ray shielding means is formed of using a heat-ray reflecting film, and plural through holes are formed in the heat-ray shielding means. The heat-ray reflecting film structure can cultivate plants by the agricultural greenhouse utilizing sunlight economically and efficiently as it has a structure that narrow band-shaped tapes obtained by cutting a multi-layer laminated film made by laminating at least two kinds of resin layers with different refractive indices alternately and having an average transmittance at 80% or more for visible light and an average reflectance at 70% or more for heat-ray is woven or knitted as a warp or a weft.

The invention relates to biaxially oriented, UV-stabilized polyester films incorporating silicon dioxide particles as light-scattering particles and a UV stabilizer; a process for producing the same and to use thereof in greenhouse blinds. The invention particularly relates to single- or multilayer polyester film with transparency from 70 to 92 %, where: the film includes at least 1.0% by weight to at most 2.5% by weight of SiO.sub.2, with the d.sub.50 value of these SiO.sub.2 particles ranging from 3 to 9 μm, the SV value of the film is at least 700, the scattering factor SF of the film is at least 2 and not more than 8, the haze of the film is from 60 to 95%, and the clarity of the film is from 15 to 40%; and all of the external layers comprise at least 0.3 % by weight of an organic UV stabilizer.
