How do i recognise RHP substrates?

Membership of the quality mark is always stated by RHP acknowledgement or by RHP-logo

On the packaging, the delivery note or on the invoice of the substrate, that is delivered with RHP certification, the membership of the quality mark is always stated. This occurs by RHP acknowledgement or by statement of the RHP-logo.


The certifications below are relevant for horticulture:

For the raw materials peat and compost and for end products, the field of application is also always stated. The RHP certification has six different fields of application:

  • RHP Horticulture (Horticulture)
  • RHP Mushrooms (Horticulture)
  • RHP Consumer (Consumer)
  • RAG Landscaping (Landscaping)
  • RAG Green Roof (Landscaping)
  • RAG Soil supply (Landscaping)


If no field of application is stated on the packaging, you can trust that the product complies with the standards for RHP Horticulture.
