Growing Media Quality Standards

The Responsible Sourcing Scheme (RSS) assesses the environmental and social impacts associated with sourcing growing media ingredients. Product quality and performance are also important considerations when selecting growing media.

The Growing Media Association (GMA) is finalising its quality standards for growing media, providing guidance for manufacturers and information for growers and retailers.

Further information coming soon

The GMA quality standards are undergoing final revisions. Further information and links to the completed standards will be added to this page once available.

Please check back for updates.
