What are growing media?

A range of growing media are available in as many product specifications. For some cultures, a raw material is used as a pure substrate and for other cultures a substrate mixture is used that is made up of, for example, peat and one or more other raw materials such as coir, wood fiber or rice hulls.

Distinctive RHP quality

With the RHP quality mark you increase the security that the substrate complies with the quality requirements concerning for instance water uptake, air content, pH, EC and nutrients. It also offers more security that the substrate is pure and clean and that it can be used without risks for the culture. The RHP quality mark monitors the quality of growing media in the chain, from raw materials production until processing and delivery at the company of the user.
