The requirements 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 requirements will come into effect on 1 May 2026. What are the changes this year?
The most important changes decided by the Central Board of Experts can be found in the CCvD List of Resolutions. This list can be found at My RHP in the folder Documents for RHP certification. All changes are included in the updated RHP product certification scheme that has been published at My RHP on 30 January 2026. After publication, certified companies have 3 months - until 1 May 2026 - to implement the adjusted requirements in their business operations and quality management system.
