The Plant Empowerment book

The basic principles

Plant Empowerment has become the new standard cultivation method for the Dutch horticultural industry in recent years. For this reason, the authors ir. P.A.M Geelen, ir. J.O. Voogt and ing. P.A.M. van Weel decided to write a new and extended version of their successful Dutch book “De basis principes van Het Nieuwe Telen” in English. The theory and practical approach of Plant Empowerment is explained in the book (350 pages) “Plant Empowerment: the basic principles”.

Since 2007 he has owned the independent training and consultancy bureau His research into the relationships between plant balance and greenhouse climate from a physiological perspective significantly contributed to the development of the Basic Principles of Growing by Plant Empowerment.

ir. J.O. Voogt

Jan Voogt studied electronics and sensor technology at the Technical University, Delft, The Netherlands. During the past 40 years, he has been involved in the devolopment of greenhouse climate control systems at Hoogendoorn Growth Management and since 2000 he has also been working for His particular fields of interest are the physical backgrounds of plant behaviour and the interactions between macro and microclimate conditions in greenhouses. He believes that cultivation methods based on plant empowerment form the primary key to sustainable horticulture.

ing. P.A. van Weel

Peter van Weel had a rich 42-year career as a researcher at Wageningen University & Research developing various innovative systems that are common in today’s greenhouses, such as ebb and flood watering, roof cleaning, movable benches and aquaponics systems. Together with Jan Voogt, he developed the climate control strategy “Aircokas” based on monitoring stomatal behaviour and optimizing photosynthesis that is described in a patent and an ISHS publication (2008). After his retirement in 2016 , he started the private company Weel,Invent to develop integrated, robust, low-investment and uncomplicated production systems for greenhouse cultivation.
