34000m² - Fresia
Marcel Tesselaar, The Netherlands
Certhon has converted the existing nursery to the current needs of the grower: a 34,000 m² Freesia nursery where the soil temperature is controlled by the in-house developed Clima Terra system. In the greenhouse, the temperature is achieved by using aquifers and a hoistable grow tube and ground cooling system. The electro technical control of the soil temperature, heating and sources and a grow lighting system with various grow light levels are also realized by Certhon.
