BVB Substrates is RHP certified. RHP has been the European centre of knowledge for growing media (both for professional growers and retail) since 1963. RHP certified substrates provide an optimal start of growth. The quality mark you ensures 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 cultivation. 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.


Our production sites in Grubbenvorst and De Lier are ISO 9001:2015 certified. ISO is the international standard for quality management. In order to be certified to ISO, a company must follow the requirements set forth in the ISO Standard. A company, for example, needs to have its quality policy ready and it has to be known throughout all levels of the company. Next to that an ISO certified organisation has to strive for high customer satisfaction levels and have clear processes. This ensures the customer of the best quality in product and service.
