RHP has developed a unique system for quality control throughout the whole production chain of substrates. RHP certified companies have set up their production processes in accordance with the RHP standards. Substrates with the RHP Horticulture quality mark offer the highest possible quality and safety and thereby guarantee an optimal start of the culture.
RHP substrates are free of contamination with heavy metals, radioactivity, weeds seeds, insects, plant and human pathogens, according to the RHP standard. The quality mark ensures that the substrate complies with the quality requirements for water uptake, air content, pH, EC and nutrients. The chemical and physical specifications have to be predefined, ensuring that each substrate delivery is consistent in properties.
