But light distribution, achieved through control of light diffusion, is often overlooked when discussing light quality for plants. Light quality should not only be thought of as light spectrum but also should include light diffusion.
From sunlight to supplemental lighting, let’s take a look at light diffusion and which greenhouse film is best suited for your unique cultivation requirements.
What is Light Diffusion?
Simply put, light diffusion is the scattering of light. It is photons bouncing around in all directions. In its most simple form, think about standing under a large outdoor shelter when the sun is highest in the sky. If there was no diffusion of light at all, it would be very bright outside the shelter but totally dark under the shade of it. The reason we can still see well in the shade is the natural diffusion of sunlight by our atmosphere.
