Polyhouse Farming In India

A polytunnel or polyhouse or hoop greenhouse or hoophouse, grow tunnel or high tunnel is a tunnel typically made from steel and covered in polyethylene, usually semi-circular, square, or elongated in shape. The interior heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. Polyhouses are mainly used in temperate regions in similar ways to glass greenhouses and row covers, it can also protect crops from intense heat, bright sunlight, winds, hailstones, and cold waves. Every factor influencing a crop can be controlled in a polytunnel. Polytunnels are often used in floriculture and plant nurseries, as the revenue value of the plants can justify the expense. Polyhouses can use energy to heat and ventilate them, particularly in colder climates. This can result in increased carbon emissions and energy costs. A female
