RHP certified substrates PROVIDE an optimal start of your crop
The RHP certificate increases 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 grower. All this may be expected from growing media with the RHP quality mark.
