The Plant Empowerment Academy is a project of the Plant Empowerment Authors. The Academy is independent. Products and activities are not sponsored by commercial parties.
For the practical application, we are open to collaboration, because suppliers play an essential role in Learning Communities in which growers are guided in their learning process, while at the same time consultants and product developers receive valuable feedback from the other participants.

We are pleased that several supplier partnerships are already active:

Plant Empowerment implementation partners

This is a group of internationally operating commercial companies that want to contribute to making greenhouse horticulture worldwide more sustainable. They are inspired by the principles of Plant Empowerment as a common basis for their services and the application of their products in practice. More about these companies, their solutions and the experiences of growers with these can be found on the website:


In addition, there is a group of six commercial companies that have organized themselves under the name of SIGS partners. All six partners work together as a multidisciplinary team to provide advice and guidance to growers who value extra support when adopting the Plant Empowerment philosophy.  More about these SIGS partners can be found on this website:

The book

“Plant Empowerment the basic principles”

Plant Empowerment is an integrated approach to the cultivation process that is based on the natural vigor of plants and uses physiological and physical principles instead of green fingers and feeling. Moreover, Plant Empowerment is universally applicable for all crops, all occurring climate zones, and various types of greenhouses.

The authors of “Plant Empowerment the basic principles”, ir. P.A.M. Geelen, ir. J.O. Voogt and ing. P.A. van Weel have given a powerful innovative impulse to the worldwide pursuit of sustainable and profitable greenhouse horticulture.

Since its introduction in 2018, Plant Empowerment has enjoyed increasing international interest from growers, researchers, consultants, knowledge institutions, and policymakers. The book, which is available in Dutch, English, and Spanish, has already sold many thousands of copies in more than thirty countries.
