Understanding pH & Eh

Behind every resilient crop lies a delicate balance of energy, nutrients and natural defence mechanisms. In this free webinar, you’ll discover why the relationship between pH and Eh (redox potential) is one of the most important, yet least understood, foundations of plant health. Learn how understanding these natural processes can help you grow stronger, healthier and more resilient crops.

The science behind plant health

Plants don’t become resilient by chance. Every day they produce energy, transport nutrients and activate their own defence mechanisms. But are we creating the right conditions for them to do so?

During this webinar, Mark van der Werf will explain the fascinating relationship between pH and Eh in a simple and practical way. No complicated chemistry, but clear insights that help you better understand how plants function from the inside out.
