About us

Deep-rooted knowledge of crops combined with a professional vision on LED lighting. When two sustainable innovators join forces, a great initiative flourishes. Together we enlighten the work of growers.

Ledgnd: LED lighting for greenhouses

The company that looks for lighting solutions for all different kinds of crops. After all, every crop needs something different in order to grow optimally. Our expertise in both areas has made us a unique player with an extensive network in the greenhouse horticulture sector.

We grow light. You grow crops.


Why LED lighting in greenhouse horticulture?

It is clear that the greenhouse horticulture sector is leading the way in sustainability. The trend for all growers is to switch to an energy-neutral system. LED lighting in greenhouses is an important factor in this trend. Are you curious about how you can participate in this global trend towards sustainability? Begin your own success story and contact Ledgnd as a valuable discussion partner with technical know-how about LED lighting in the horticulture.


Optimal light for plants and crops

What do you want to achieve with your crop? And what is your future dream as a grower? Ledgnd looks futher and helps you to achieve your business goals. Our method allows us to be a trusted advisor for you as a grower. After all, we are growers ourselves and we look at lighting from a brand-independent perspective. A thorough investigation results in advice around greenhouse lighting that you can build on.


Whereas Matthea Rijneker focused on horticulture with Potted Plants, Richard van de Vrie of Luximprove specialized in professional lighting projects from a brand-independent perspective.

Ramón van de Vrie saw this as an opportunity to pursue his passion. As a Horticulture Lighting Researcher, he created the link between both worlds. And that is how Ledgnd saw the light of day.

Scientific Researcher

Fokke Buwalda

Fokke started his career as Scientific Researcher. First at PPO and later at Wageningen UR Greenhouse Horticulture. He has developed dynamic simulation models to gain insight into the crop as a system. However, the application of those simulation models in practice, was disappointing. At the end of 2013 he became the founder of B-Mex B.V. and started to be fully committed to developing online advisory services to make that valuable knowledge practically usable for entrepreneurs in the horticulture. A collaboration contract has been concluded with Wageningen UR, which gives B-Mex access to the latest scientific information. Fokke is involved within Ledgnd with the portal for crop registrations called MyLedgnd. In this portal, growers can monitor and analyse the results of LED on the crop. Fokke’s experience and expertise in various crops is of enormous value in the realization of successful LED projects.
Biosystem Engineer

Peter van Beveren

Peter studied Biosystems Engineering at Wageningen University. Since 2011 he has been working on a PhD research on energy management in greenhouse horticulture and since September 2020 also on the MyLedgnd portal. The modelling of the greenhouse climate and optimization play an important role in this. Peter has worked at B-Mex since 2015 and has been co-owner of B-Mex since 2017. At Ledgnd, Peter works on developing new applications and continuously improving the existing portal. In this portal, growers can monitor and analyse the results of LED on the crop. Peter supports growers to successfully switch to LED solutions. Peter’s knowledge of energy management and climate in the greenhouse are of great importance in this process.
Plant Scientist

Jeroen Boonekamp

Jeroen studied Plant Sciences at Wageningen University. During his studies, he specialized in modelling the effects of greenhouse climate on the plant growth. After his studies, Jeroen started working as a practical researcher. He soon came to the conclusion that there is a lag with models in cultivation. He has therefore been working for B-Mex since 2020 to implement crop models in the daily crop management, including within the MyLedgnd portal. In this portal, growers can monitor and analyse the results of LED on the crop. Jeroen will support growers to successfully switch to LED solutions. Jeroen's knowledge of the implementations of the models plays a major role in this.
