What if the secret to stronger plants isn’t another product, but a process you understand? Behind every resilient crop lies a delicate balance of energy, nutrients and natural defence mechanisms. In this free webinar on June 30, 2026 (3.30pm CEST), you’ll discover why the relationship between pH and Eh (redox potential) forms the foundation of plant health and why understanding these principles can completely change the way you look at your crop.

Understanding pH & Eh

The science behind plant health
Plants don’t become resilient by chance. Every day, they produce energy, transport nutrients and activate their own natural defence mechanisms. The question is: are we creating the right conditions for them to do so?
In this free webinar, Mark van der Werf will explain one of the most fascinating concepts behind the Plant Empowerment philosophy: the relationship between pH and Eh (redox potential).
Although these terms may sound scientific, the principle behind them is surprisingly simple. Once you understand how these processes work together, you’ll gain a completely new perspective on plant health and resilience.
