Which different diffuse coatings are available?

Diffuse coatings are developed for crops that require a lot of light, but could still use some protection from warmth and direct sunlight. However, within this group there are small differences in needs of sunlight and warmth. Certain crops, like chrysanthemums or gerberas can use some light, but not as much as other crops, like bell peppers and cucumbers. Therefore, various diffuse coatings, which differ in terms of light diffusion (Haze) and light transmission are used.

Please note: diffuse coatings have a different function than chalk shading agents

Optimal circumstances

By “playing” with the amount of light diffusion (the so-called Haze factor), an optimal ratio between the use of light and crop protection is created. The diffusion of light affects the light transmission. Less light transmission is a result of a high Haze factor, while a high degree of light transmission equals a small degree of light diffusion. 


The high light transmission and high Haze factor of D-Fuse should make it possible to handle crops that are highly resistant to irradiance. D-Fuse only shades 2 to 3% of the growing light and has a high Haze factor with light diffusion of 86%.


D-Fuse Extra

D-Fuse Extra is meant for crops that can use a lot of light, but need a little more protection from the sun. That is why the Haze factor in this product is higher than in D-Fuse, namely 95%. This provides better protection against radiation, because a higher Haze factor leads to better spreading of the light and heat over a larger surface. The light transmittance is set to offer more protection to the crops: 9 to 11% of the light is shaded.


Within the group of sun and light-loving crops, there are species that require a lot of light, but are clearly more sensitive to warmth and radiation than others. An amaryllis or rose, for example, is more likely to be affected by stress caused by heat, than other floricultural crops.  Some soft fruits and herbs also require a lot of light, but need extra protection from heat and radiation than other crops. In this case D-Gree is a good solution. This diffuse coating contains pigments that allow grow light as much as possible and, at the same time reflect heat radiation, or the near infra red light (NIR). With the shading of 15-20% PAR light, 46% NIR light and a Haze factor of 93% D-GREE provides a much cooler climate in the greenhouse.

However, not only crops that need the extra protection benefit from D-Gree. Greenhouses that have to deal with a lot of heat also benefit from this diffuse coating. These include greenhouses without a screen or atomization, greenhouses in warmer climates, lower greenhouses or greenhouses that get a lot of sun due to their location. D-Gree was developed to meet these needs for both plants and greenhouses. 

Simple removal

As much as these three products differ in a number of aspects, they also have three important similarities: one dosage, a long lifespan and a high degree of light diffusion. At the end of the season all three products are easily removed with a remover.
