Independent & Objective

About HortiQ

HortiQ was established in 2009 to provide guarantees for greenhouse horticulture entrepreneurs and investors that greenhouse construction, heating and irrigation systems are constructed and installed according to objective and verifiable quality standards. 


Our HortiQ team of professionals works hard towards quality improvements within the (greenhouse) horticulture sector. They make quality assessment transparent and visible to enable clear and transparent assessment of quality, processes, services and/or products within horticulture technology. HortiQ does not provide the certification itself. Reviews and assessments are carried out by independent certification institute, KIWA.
