This article compares three common greenhouse shading screens: blackout, white, and aluminum, highlighting differences in light control, heat reflection, energy efficiency, microclimate management, and crop suitability. Blackout screens block nearly 100% of light, ideal for photoperiod-sensitive crops and flowers. White screens diffuse sunlight, promoting even growth for vegetables and fruiting crops. Aluminum screens reflect heat and light, reducing energy costs and maintaining optimal greenhouse temperatures. By understanding the properties and applications of each screen type, growers can make informed decisions to optimize crop performance, energy use, and greenhouse climate management.
