The climate inside the greenhouse is very important. Not all crops can withstand high temperatures and full sunlight. Shading and diffuse coatings are the solution to this problem. By reflecting or diffusing sunlight, they ensure that the crop is not damaged by excessive light intensity. There are several types of shading agents and diffusion coatings, each with a different effect. Find the right shade or diffuse coating for your crop.

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

Diffuse light penetrates deeper into the crop. This ensures a higher reception of light, providing higher production and better quality.

Shadefix is a whitewash in powder form, which protects the crop from light irradiation, and are frequently used in regions with dry climates.

Shading paint help crops to protect them from full sun of high temperatures. During a warm period, greenhouse roofs are applied with shading paint, also known as chalk. The paint causes the light to be reflected, reducing the temperature in the greenhouse. In this way you always maintain an consistent temperature into the greenhouse and protect the crop from light damage. Royal Brinkman offers different greenhouse shading agents. Our specialists explain in the article what a shading agent is and how to use it. 

''It's important that we can do the whole season with one layer of shade paint. Removing it at the end of the season shouldn't cause any problems either. Q4 White meets those conditions very well."

In contrast to reflecting light with shading, some crops are more light demanding  and therefore they need a higher light transmission. Diffuse coatings are designed to maximize light transmission rather than reflection. This results in increased light penetration into the greenhouse, which promotes better plant and fruit growth. In floriculture, diffused light has been shown to increase growth, while in vegetable production, it increases production and improves crop quality. 

What are the benefits? Diffuse light penetrates crops more evenly and deeply. The application of diffuse coatings in greenhouses is a technique used to improve the light efficiency of crops, thereby increasing yields and creating optimal conditions for growing tomatoes and peppers. If you prefer diffuse coatings, there are several options available, each designed to meet specific crop requirements. These coatings vary in their level of light diffusion and transmission. See the article "Which types of diffuse coatings are available?" to explore the options.

"The light penetration was better and the crop was significantly less stressed. As a result, it remains active longer and you get more production. We are very satisfied with this diffuse coating."

What is the difference between powder and liquid shading agents? 
The main difference between liquid and powder agents is their composition and form. Liquid shading is easier to mix and dose with water before applying. On top of that, liquid shadings are more weather-resistant. In dry climates, powder agents will fullfill your needs. When only a short period of shading is necessary, poweder agents could be an option. Our specialists have written an article in which they tell you all about the differences and effects of liquid and powder shading.

How to remove of greenhouse shading?
It is important to remove the shade paint from the greenhouse roof at the end of the summer. This will allow the plant to take full advantage of natural growing light. To remove shading paint from your greenhouse roof, we recommend the use Removit, developed by Hermadix,. This cleaner is used to remove greenhouse paints such as Q3 and Q4 and the diffusion coatings D-Fuse and D-Gree. Our specialist will give you some tips on how to remove shading paint from your greenhouse.

How much shading does my crop need?
Crops respond uniquely to different light and climate conditions. Light-demanding crops such as roses, tomatoes, peppers and cucumbers thrive in full sunlight but require protection from excessive radiation. Conversely, shade-loving plants, including many potted plants and orchids, benefit from significant shade. Contact our specialists for custom advice. 
 
What is the best shade percentage for a greenhouse?
The optimum shade percentage for the greenhouse is 65% as this provides longer lasting protection. Q4 White has a life span of 8-25 weeks depending on dosage. You can increase the percentage of white by adding more product for increased shade. However, some crops are sensitive to excessive greenhouse shading paint that exceeds the 65% percentage. Q3 can be used for higher shading percentages, but is less weather resistant and more suitable for short term shading. In contrast, Q4 White is highly weather resistant and therefore more suitable for longer periods or seasons.
