Agricultural Half Shade (Nurseries, House Shade, Greenhouses)
In technical horticulture and floriculture, the key is to reduce the heat and water stress of the plants, this is achieved by keeping the ideal temperature range for each type of crop as constant as possible. Preventing plants and fruits from being subjected to strong thermal deltas prevents the plant from producing weight and the fruits from becoming stiff or cracking (a phenomenon well known with tomato crops (tomato). Temperature is controlled by directing the shade house or greenhouse according to the prevailing winds and the latitude of the crop, and increasing or decreasing the height of the structure and its ventilation systems.The shade netting can be internally retractable screens that move automatically with temperature sensors, or external fixed ones. The degree of shade required varies by crop and geographic area, but generally vegetable crops can work with shadows of 35% to 50% coverage, while flowers may require more coverage but a cooler shade using silver-colored fabrics (there are photo-selective shadow meshes that allow manipulating some specific variables of the crop acting on the spectrum of light).
