Diffusion of the light ensures that the light reaches deeper into the crop, illuminating a larger leaf surface area and allowing more photosynthesis to take place. This benefits the growth of the crops.The plant can take in and process more CO2 to assimilate for growth, production and quality.

Diffused light also results in fewer high peaks in leaf temperature, reducing plant stress. By diffusing the direct light, more light can be admitted, accelerating growth. The crop is more generative and the fruits develop quicker. This is because the morphology and development of the crop changes under the influence of diffused light. Under diffuse glass, there is less photo-inhibition as there is less direct light in the greenhouse. In photo-inhibition, the leaf cannot process the large quantity of light energy and, as a result, the photosynthesis system is damaged.
