A flat roof shade net house is a protective structure featuring a flat-roofed frame covered with a shade net, designed to reduce the intensity of sunlight, regulate temperature, and enhance air circulation for better plant growth. It provides an ideal environment for cultivating a variety of crops, including vegetables, flowers, fruits, and medicinal plants, by protecting them from excessive heat, pests, strong winds, and hail. This structure supports the growth of normal crops while ensuring better ventilation, creating a balanced microclimate that minimizes plant stress and improves productivity.
