Three kinds of greenhouse glass, which one do you prefer

Glass greenhouses have gradually begun to replace film greenhouses and solar greenhouses. The overall outbreak of glass greenhouse lies in whether the cost of greenhouse can be reduced. At present, the construction cost of glass greenhouse is still too high for ordinary growers, which keeps many investors away.

At present, it is known that the investment of glass profiles in the construction of greenhouse accounts for about 15%, and the main specifications are low, medium and high. The low end is ordinary float glass, the middle end is ultra white scattering glass and the high end is ultra white antireflection glass.

The so-called "one price, one goods". The three types of glass in the greenhouse are also very different in terms of greenhouse planting benefits and yield increase. First, let's talk about ordinary float glass. The light transmittance of ordinary float glass is up to 88% - 89%, which has a certain shading effect and is not very friendly to greenhouse planting. In rainy days or insufficient light, it is easy to lead to insufficient photosynthesis and light absorption of greenhouse crops, affecting falling flowers and fruit setting.

Then there is the ultra white scattering glass. The transmittance of 91.5% is fully sufficient, and the scattering glass has a certain scattering light effect, which can increase the light coverage to a greater extent. Light can irradiate the roots of crops to ensure that they will not become diseased. The ultra white scattering glass can also screen the light, eliminate the ultraviolet light not required for plant growth, and retain the blue and purple light required for plant growth. The blue and purple light can effectively improve the crop yield, and the content of nutritional elements in the fruits and vegetables is several percentage points higher than that in ordinary planting.

Finally, the ultra white antireflection glass is an advanced version of the ultra white scattering glass. On the basis of the original scattering glass, the transmittance of the glass is increased. The transmittance of blue and purple light of the antireflection glass can reach 97.5%, and the yield increase benefit is about 15% higher than that of the ultra white scattering glass. Antireflective glass is the best glass that can be used in greenhouse at present.

It is recommended to use 4mm ultra-thin scattering glass for greenhouse glass. The price is moderate and can increase the growth of greenhouse crops. Ultra white antireflective glass is usually used in high-end greenhouses, scientific research greenhouses, seedling greenhouses, etc.
