A greenhouse coating that gives light a new meaning

PAR+ coating

Giving crops the vitamins they need

Our expertise in the field of coatings for glass has led to the development of luminescent coatings that convert harmful UV light into photosynthetic active radiation, otherwise known as PAR light. We call this coating PAR+. This convergence allows for a 7% increase in crop growth for fruit vegetables grown in greenhouses, without the use of additional artificial lighting.


Control the last variable

Our luminescent and anti-reflective coating converts ultraviolet light into additional PAR light with a relative boost in the blue spectrum of 400 - 550 nm, resulting in 7% more functional light for crop growth. 1% more PAR light allows for 1% more crop growth of fruit vegetables like tomatoes, strawberries and bell peppers without the need for artificial lighting using unnecessary energy.


PAR for two crop types

For fruit vegetables, 1% of increase in PAR = 1% of increase in crop yield. For potted plants and bedding plants, the relative increase in the blue spectrum reduces stretching, effectively making PAR+ a sustainable alternative to hormonal stretch retardants. Next to this, PAR+ inherently makes the light diffuse, another proven process of boosting crop yield.
