Aldo van Os is a fourth-generation grower and entrepreneur in greenhouse horticulture. For the first ten years of his career he grew crops using the conventional ways, switching to organic practices twenty years ago, constantly deepening and broadening his experience and knowledge of methods that do not rely on synthetic chemicals for either soil conditioning or pest control. Aldo’s sound approach gives his organic business a modern and solid commercial and technical foundation. With over 25 years of experience Aldo is now an international consultant and helps other growers transition from conventional to biological practices or simply improve the current organic growing practice. At this moment he is working on projects in Germany, the Netherlands, Canada, the US and Mexico.
