A greenhouse is a structure with walls and roof mostly constructed of transparent material, such as glass, in which plants that require controlled climatic conditions are cultivated. These structures come in a variety of sizes, from modest sheds to large industrial constructions. Greenhouses provide you more control over the environment in which your plants thrive. Temperature, amounts of light and shade, irrigation, fertilizer application, and air humidity are all aspects that may be regulated depending on the technical specifications of a greenhouse. Incoming solar radiation from the sun warms plants, soil, and other objects within the building quicker than heat can exit the structure, causing the inside to heat up. The roof and walls keep warm air within the house that has been warmed by the heat from heated interior surfaces. HSI provides Trunkey solutions for green house and tunnels
