Natural ventilation uses the opening sides, opening roofs and opening ends to allow natural airflow through the greenhouse and provide temperature control. Natural ventilation has the advantage of being less expensive.
Mechanical ventilation using extractors, fans and dampers is used mainly in the cold season when natural ventilation is not possible or as a complement to natural ventilation in the warm season. However, the operating costs are higher. To evaluate your needs in terms of ventilation, do not hesitate to consult one of our representatives.
