Petra van de Vrie
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 My Ledgnd. 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.

Matthea Rijneker
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 My Ledgnd 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.

Joris Elstgeest
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 in his opinion 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 Ledgnd 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.
