In greenhouses, the reflection of sunlight At the ground level more light reaches the plants especially on overcast days. Compared with the black canvas, the white canvas gives a 10 times greater reflectivity for the light area of ​​plants with photosynthesis (parallel steps of 400 ~ 700nm). (thereby helping to improve the photosynthetic efficiency of plants).  
White canvas to make the greenhouse brighter and easier to manipulate in the greenhouse. (Improved production efficiency)
White canvas also allows heat reflection, which helps to limit hot floors.
