About the workshop

Water and oxygen are essential for the plant and its roots, but when are both optimally present? What is the course of its contents in the root environment? By combining analyses and measurements – that you can do yourself – in the culture, it becomes clear how it works and how you can optimise this yourself.

What can you expect?

The latest results of the collective research are presented and cross connections with existing knowledge of water and air are discussed. After this workshop you are entirely up to date in the field of water contents, water uptake and air.


During this workshop you will get answers to the following questions:

  • Which processes concerning water happen in the root environment?
  • Which measurements and analyses give insight to these processes?
  • How can these processes be influenced?
  • Which analyses make the relation between quality of the substrate and the culture measurable?
  • What are the effects of various irrigation strategies and irrigation systems?
  • What is the best way to measure with water contents sensors?

For whom?
This free workshop is meant for advisers that provide growers with substrates advice. The only requirement is that your company is a member of RHP. The workshop is organised at Stichting RHP, Galgeweg 38, 2691 MG ’s–Gravenzande, with the exception of the in-company workshops.
