To enable the transition of greenhouse horticulture to a sustainable future, it is essential that all stakeholders work together based on the same vision and principles. Plant Empowerment provides the foundation for this.

We are facing the enormous challenge of providing all stakeholders in the sector with the right knowledge and also organizing cooperation for the further development of this knowledge

Ambassadors play an essential role in Learning Communities in which growers are guided in their learning process, while at the same time researchers, teachers and students learn from practice.

It is, therefore, gratifying that a growing number of Ambassadors of our Academy, both in the Netherlands and internationally, promote and apply the principles of Plant Empowerment.

Wireless Value

Under the slogan, “We make measuring easy. Everywhere. “, Wireless Value continues to develop a robust wireless measuring system in greenhouses for Climate, Plant and Water. Because the sensors can be deployed anywhere, this offers the grower optimal ease of installation and flexibility. Gaining better insight into the plant and greenhouse balances for energy, water, and assimilation supports the grower in making daily decisions and makes it possible to optimize cultivation. Wireless Value thus contributes considerably to implementing the Plant Empowerment principles and the uniform measurement protocol according to Plant Empowerment Digital Growing.

Sigrow’s mission is “To save plants from bad microclimates”. Therefore, Sigrow designs and manufactures sensor systems for measuring the micro-climate and crops in greenhouses and vertical farms to provide reliable data and facilitate data-driven growing and AI applications. Sigrow’s sensor solutions focus on precise monitoring, visualising, and steering the plant light, air micro-climate, substrate and stomata conductance. This way, Sigrow supports growers in increasing their productivity, reducing energy costs, and minimising environmental impact. The data, visualised in dashboards, is increasingly more focussed on the application of ‘Plant Empowerment’ concepts and methods.

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.
