34000m² - Fresia

Marcel Tesselaar, The Netherlands

A Freesia nursery of 34,000 m2 where the soil temperature is controlled by the in-house developed Clima Terra system. In the greenhouse, the temperature is achieved by using aquifers. The electro technical control of the soil temperature, heating and sources is also realized by Certhon.

We have realized:

• The already existing nursery is converted to current needs;
• Hoistable grow tube heating and ground cooling;
• An aquifer consisting of 3 well pump installations with a total capacity of 260 m3, by which the heat pump can add cold;
• CO2 dosing installation system;
• A grow lighting system with various grow light levels (68 en 132µmol /m²/sec);
• Clima Terra provides the optimal soil temperature with a total of 60 soil sensors and valve groups.
