What is a shading agent?
Not many crops can bear full sun or high temperatures. This is where a shading agent 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
A shading agent 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; a shading agent improves the climate of 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 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 shading product which is wear-resistant. It is also possible to chalk (meaning: apply a shading agent) 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 a shading agent
Most growers choose to apply their shading agent 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 shading agent. Holes or stains let light through, meaning the crop is not protected entirely.
