Greenhouse shade paint and diffuse coatings

A solution for every crop to maximize sunlight

Having the right climate in your greenhouse is critical. Not all crops can handle high temperatures and full sunlight. By reflecting or diffusing sunlight, you ensure a crop won’t be damaged by excessive light intensity. There are a variety of shading agents and diffuse coatings for your needs.

Wondering how greenhouse shade paint and diffuse coatings can benefit your crop?


Benefits of using diffuse coatings

  Eliminates shading formation
  High light transmission and light scattering
  Higher valuable photosynthetically active radiation (PAR)


Greenhouse shading agents offer reflection

As a grower, you want a stable climate in your greenhouse to create the perfect growing environment for cultivation. This means temperature peaks need to be reduced. Greenhouse glass paint, also called whitewash, will help create a stable greenhouse climate. Shading agents reduce greenhouse temperature by partially reflecting sunlight, which protects your crop from the heat of the summer sun.


Shading agents

As greenhouse construction has evolved, and spraying techniques have become more sophisticated, the demand for a more advanced chalking system has also increased. It needs to be easier, faster, safer, and more accurate. To meet this demand, two types of shading agents have emerged: liquid, and powder shading agents. Each one has unique advantages, depending on your needs. Liquid shading agents Q3 White and Q4 White are both calcium carbonate based chalk agents that provide a different layer of protection.

Two more products that provide stress reduction for plants are Q-Heat and D-Gree. Q-Heat is a screen material that reflects heat radiation away, which means a cooler greenhouse climate. D-Gree is a diffuse coating that provides maximum diffused light and maximum growth light (PAR) transmission. It contains specially developed pigments allowing for maximum growth light (PAR) ingress while reflecting thermal radiation.




Liquid shading agents

Q3-White and Q4-White are weatherproof and adjustable shading agents for creating the optimal greenhouse shading conditions.



Diffuse coatings

Diffuse light penetrates deeper into the crop. D-Gree and D-Fuse ensure a higher reception of light in the greenhouse, providing higher production and better quality.

Greenhouse diffuse coatings offer transmission

Unlike shading agents, diffuse coatings are designed to let as much light through as possible. Instead of reflection, diffuse coatings provide transmission. This means a higher amount light reception in the greenhouse, and better growth of crop. In floriculture, diffused lighting has proven to lead to higher growth, and in vegetable cultivation it has proven to increase production while improving crop quality.


Diffuse coatings

Diffuse light penetrates more homogeneously and deeper into the crop. Diffuse glass on greenhouses improves the light use efficiency of greenhouse crops, which increases yield and offers ideal conditions for cultivation.

If you choose a diffuse coating, there are many kinds of coatings to pick from. The one you should choose, will depend on the needs of your crop. The difference between various coatings is in the light diffusion and light transmission. 

Diffused glass has become increasingly popular, especially in vegetable cultivation, in recent years. The effect of both diffused glass and diffuse coating is the same: they create diffuse light in the greenhouse with a low to high degree of diffusion. The differences between diffuse glass and a diffuse coating affect price, flexibility and durability.





At the end of summer, when the temperature drops, it’s important to remove shade paint from the greenhouse roof so the crop can maximally benefit from natural grow light. Removit is specially developed to remove Hermadix shading agents. Our specialist offers tips on how to remove shading paint from the greenhouse.
