What is a shading agent?

Shading agent
















Written by Lars Ammerlaan | Last update: 24-10-2020

Not many crops can bear full sun or high temperatures. This is where a greenhouse shading paint can offer protection. The crops in the greenhouse can be protected with a layer of chalk, to reflect light and heat in the summer. This prevents climate peaks within the greenhouse, protection the crop throughout the entire season. 


Improvement of the greenhouse's climate 

The greenhouse shading paint reflects light and lowers the temperature in the greenhouse. As a result, less evaporation within the crop occurs, preventing the plant from drying out and hanging loosely. It can be stated; the greenhouse shading paint improves the climate in the greenhouse. Eventually, this leads to less stress for the crop and a better result.



Preventing roof-ridge wear off

Signs of wear on the roof-ridge is very disadvantageous to the crop. Therefore, it should be minimized. The roof-ridge is very important in greenhouse shading, since this part of the greenhouse gets most of the sun, from morning till evening. Also, the roof-ridge is affected by rain, hail and wind. Therefore, it is crucial that the roof-ridge is covered properly. For this, you can use a high-quality greenhouse shading product which is wear-resistant. It is also possible to chalk (meaning: apply greenhouse shading paint) several times with a relatively cheaper product, which is less wear-resistant. It is recommended to always ask for advice when choosing a specific product.

Apply greenhouse shading paint

Most growers choose to apply their greenhouse shading paint mechanically by hiring a threshing contractor. This guarantees a correct application of the product, in the right quantity. It is also an option to apply this product manually. However, this brings along risks. The method of working is less precise, with the result of certain parts of the deck not being sufficiently covered. This could result in holes or stains in the layer of the greenhouse shading paint. Holes or stains let light through, meaning the crop is not protected entirely.
