ReduFuse or ReduFuse IR?

A few years ago Mardenkro introduced ReduFuse. It is a coating that diffuses sunlight while hardly reducing light transmission. It is used mostly in the summer months for vegetable and flower crops that normally are not, or very minimally, screened. It’s clear from the graph below that light transmission across the entire spectrum remains virtually the same.

ReduFuse is not a shading product so it’s less commonly used for crops that require shading. These include sun loving pot plants, different types of cut flowers, and vegetable crops in warm countries. Diffuse light certainly has advantages for these crops, which can be read about, for example, in the article “Pot plants benefit from diffuse light”. ReduFuse alone is therefore not sufficient for these crops and they will still require additional shading. Therefore Mardenkro developed a coating that diffuses the light and at the same time screens out part of the infrared light. This coating, just like ReduFuse, has a high haze factor of at least 70%. Light transmission is slightly lower than that of ReduFuse in both the visible light spectrum and that of PAR light. ReduFuse IR is therefore less suitable when it’s important to maximise the amount of light in the greenhouse. By applying the ReduFuse IR coating it’s possible to benefit from diffuse light during the whole summer and there’s less need to screen the crop with a shade cloth.
