For growing plants in a greenhouse, the main problem is overheating of the soil. Someone shades their plants with improvised methods: who breeds chalk and whitens the greenhouse from the inside - the chalk dries up and slightly shades the plants, and after the hot season the whitewash is washed off. Someone covers the greenhouse with spunbond from the inside, for me it is not convenient.
Today, many people use greenhouse shade netting to help protect plants from the scorching sun.
The shading net prevents the rapid evaporation of moisture from the soil (due to this, you can reduce the number of irrigations), creates favorable conditions for the growth of fruit crops, helps increase productivity, forms a light shade in the greenhouse and lowers the temperature inside it by 5-15 degrees.
