A high-quality substrate is the basis of a successful culture. Growers must be able to be 100 percent confident that growing media, such as potting soil or mineral wool, meet the highest requirements. As the knowledge centre for substrates, RHP is an internationally active organisation that has played an essential role in this for years. We are working at the highest level to improve the quality of growing media. Valuable knowledge is developed through innovative research. Transferring this knowledge to the affiliated substrate producers worldwide is an interesting and challenging process every day. Knowledge, commitment and enthusiasm are paramount for the employees. For a new colleague in an experienced team, this is a special opportunity!
