Light is the most precious gift that we can get from nature, especially for the greenhouse plants. When crops enjoy the benefit from the sunshine, the uncertain light fluctuation (e.g. shading, light spot or high light intensity) is undesired in crop production. Therefore, the diffused light is introduced to help us to receive this gift wisely in the greenhouse.

What is diffused light?

Diffuse light means light is scattered , causing it to fall on the crop leaves from all directions. The light is evenly distributed, leaving no obvious shadows. Diffuse light is generated when direct light is scattered naturally (e.g. clouds) or artificially (e.g. diffuse glass).

What is the meaning of diffused light in greenhouse growth?

Due to the construction of greenhouse, shadows always appear on the leaves and in between crops, which create uneven climate distribution. So diffused light can avoid this issue properly through improving spatial light distribution, leading to a homogenise climate distribution within greenhouses. So that crop will get more benefits during this process as shown following:

1. Shading and inter-shading are avoided, which avoids light loss. 

2. Crop canopy is not damaged by excessive light intensity without loss of light, which avoids crop damage.

3. The diffused light is more accessible of leaves on the crop belly and bottom level, which optimizes light use efficiency and increase the yield. 

4. The vertical temperature gradient is released, which ensure more even growth, which decreases the crop stress. 

Besides, considering a user-friendly environment, diffused light can help grower to lesson the discomfort caused by direct sunlight.
