Last Spring the Dutch grower association Rainbow acquired an existing poly greenhouse in northern Tunisia that is suitable for the production of young plants. The plan to grow peppers abroad in the winter months took Rainbow to many different places around the world. However, the final choice was made to 'hibernate' in Tunisia. Formerly, the company was producing young plants in the greenhouse, which was not suitable to grow vegetables in. It was decided to strip the greenhouse with the help of the company's local employees.

Van der Hoeven was then asked to create a specification for the construction of a suitable technical heating and water system. The greenhouse was already equipped with a boiler and there were preparations for a CO2 installation because the young plants had been heated with pipe heating. The company was already equipped with a climate control computer and a water unit, with which the mother plants were watered using drippers. Van der Hoeven developed a complete specification with assembly drawings. Employees from Rainbow started looking for materials for the heating system in Tunisia. 

Parts that were not available in Tunisia were delivered via Van der Hoeven. At the moment, the plants are cultivated in the Tunisian greenhouse with substrate mats on the floor. The groundwork was completed by another Dutch company. The technical heating and water system was built on- site by a local contractor, which was overseen by their own staff. Meanwhile, in week 36, the first plants were planted in North Africa and we can look back on a successful renovation.
