The black shading net has a better shading and cooling effect than the silver gray shading net. It is generally used for covering and cultivating green leafy vegetables such as Chinese cabbage, baby bok choy, Chinese cabbage, celery, coriander, spinach, etc. in the hot summer season and crops with low light requirements and light virus disease hazards. The silver gray shading net has good transparency and has a function of avoiding aphids. It is generally used for covering cultivation in early summer and early autumn seasons, as well as crops that require high light and are prone to viral diseases, such as radishes, tomatoes, chili peppers, and other vegetables. Used for winter and spring antifreeze coverage, black and silver gray shading nets can be used, but silver gray shading nets are better than black shading nets.
