Diffused glass is usually created by treating the surface of the low-iron glass to create patterns that scatter the light. The aim of using diffuse glass in a greenhouse is to produce more scattered light which can then penetrate deeper into the crop canopy. this will allow the plant to use more of the available light for production.
Diffuse Light Has a Positive Effect On the Crop
The crop is able to convert more light into growth (photosynthesis). This is due to a more uniform greenhouse climate, better horizontal light distribution, vertical light transmission and light absorption of the lower leaf layers. This increases the photosynthetic capacity of the plant.
The crop undergoes less stress, a lower temperature in the upper leaf crop layers and a higher temperature in the lower sheet layers.
The morphology and development of the crop change. The crop is more generative and the fruits develop faster. The fruits are heavier and there are often more fruits. Potted plants develop faster resulting in a shorter growing time.
In order to compensate for the loss in light transmission, both diffuse as standard float glass (single or double) can be provided with a light-reflecting coating, which means anti-reflective coating. This coating will reduce the reflectance of sun-light, and enhance light transmittance by at least 2.0%.
In addition, AR coating has good features of Hydrophilia and photocatalysis, thus AR coating glass has a self-cleaning function, and can decompose organic pollutants on the glass surface and reduces maintenance time. Glass with AR treatment can only be cleaned with (hot) water, not with fluorine, which affects the coating.
