Direct sunlight (undiffused light) can cause a “shadow†effect and “sun burnsâ€. Light diffusing additives will scatter the direct light, thereby preventing the shadow effect and sun burns. The light diffusion increases the photosynthetic efficiency by providing
more homogeneous light from all directions. This is advantageous to crops with self-shading characteristics, such as cucumbers, tomatoes, squash, roses and others. The 200 micron plastic is suitable for an area with high radiation.
