What has changed in the RHP product certification scheme?

31 january 2025

The standards of the RHP quality mark for raw materials and growing media are updated annually. This is partly done based on developments in the sector. Therefore, every year changes to the content of the RHP product certification scheme are introduced. The new standards will come into effect on 1 May 2025. What are the changes this year?

A list of the changes 

The most important changes decided by the Central Board of Experts are listed below. These changes will be included in the updated RHP product certification scheme that will be published at My RHP on 31 January 2025. After publication, certified companies have 3 months - until 1 May 2025 - to implement the adjusted requirements in their business operations and quality management system.
