A greenhouse according to the present invention includes: a ceiling portion; and in at least a portion of the ceiling portion, a glass sheet with a coating film. The glass sheet with a coating film has a total light transmittance of 90% to 98%, a haze ratio of 20% to 80%, and a hemispherical transmittance of 80% to 90%. When a test is performed according to JIS R 1703-1: 2007 by applying oleic acid to a surface of a coating film and subsequently irradiating the surface with ultraviolet light at an intensity of 1.0 mW/cm.sup.2, a time period from start of irradiation with the ultraviolet light to a point at which a water contact angle on the surface reaches 5° is 24 hours or less.

The present invention relates to an elongated sheet (1) for covering agricultural cultivated plants (2) for generating a greenhouse climate in the covered area, having an elongated basic film (3) made of plastic, wherein a ventilation area (5) extending in the longitudinal direction (L) of the sheet is provided in the central area of the basic film (4) and having a plurality of ventilation openings (6), wherein a cover film (9) of plastic extending in longitudinal sheet direction (L) of the basic film (3) is applied to the ventilation area (5) forming free spaces (11) for air exchange and is firmly welded to the basic film (3) via a plurality of connection areas (10) following one another in longitudinal sheet direction (L). In accordance with the invention, it is provided that the material and/or the quality of the cover film (9) is selected in such a manner that the cover film (9), in a first state, lies flat against and/or on the upper side of the basic film (3) at least substantially in the region of the free spaces (11) and, preferably by convection of the heated air in the covered area, in a second state at least partially lifts off relative to the upper side of the basic film (3) forming free spaces (11), wherein the first state is maintained up to a transition temperature Ti of the greenhouse climate and wherein the second state is obtained and/or realized from the transition temperature Ti of the greenhouse climate.

Self-supporting inflatable grow tents include a base surface, a top surface, and a plurality of sidewalls. The sidewalls include an integrated lighting system. The inflatable grow tents include a plurality of support members configured to structurally support the grow tent when inflated, and an air circulation assembly including an air blower and a carbon filter. The grow tents include a lighting system configured to provide a standard deviation of average photosynthetic active radiation that is from about 2 to about 8 within the grow tent when the lighting system is active.

The present invention concerns an elongated sheet (1) for covering agricultural cultivated plants (2), with a basic film (3) of plastic, wherein a ventilation area (5) extending in the longitudinal sheet direction (L) and having a plurality of ventilation openings (6) is provided in the central area (4) of the basic film (3), wherein a cover film (9) of plastic extending in the longitudinal sheet direction (L) of the basic film (3) is applied to the ventilation area (5), forming free spaces (11) for air exchange, and is firmly welded to the basic film (3) over a plurality of connection areas (10) following one another in the longitudinal sheet direction (L), and
wherein the connection area (10) is designed to be inclined, at least in some areas, with respect to a weld start point (12) and a weld end point (13) with respect to the cross direction (Q) extending orthogonally to the longitudinal sheet direction (L).

A textile barrier apparatus includes an inner layer comprising an aqueous super absorbent polymer composition (SAP) and first and second outer textile layers attached to opposite sides of the inner layer. A landfill version includes an odor neutralizer, a biocide and/or a nutrient to support vegetation. A fire barrier version has the first and second outer textile layers including water permeable membrane and a fire retardant treatment. A planting groundcover version includes a patterned thickness of SAP corresponding to a planting pattern and a nutrient to support vegetation.

A soilless system for high density plant growth includes a greenhouse structure; at least one elongate support member arranged substantially vertically in the greenhouse structure, the support member having a body having a flow channel defined therein; and a plurality of vertically spaced apart receptacles angularly disposed to the vertical axis of the body to receive a plant therein, the receptacles being in fluid communication with the flow channel; a fluid supply system in fluid communication with the flow channel to supply a fluid stream to the flow channel; and a fluid collection system to collect residual fluid that has flowed through the flow channel.
