Cooling & Ventilation for Greenhouses

Crop production throughout the summer can be difficult. The excess temperature in a greenhouse can lead to many problems. These accessories help to cool and ventilate your greenhouse so that you can create the perfect growing conditions even in the summer season. Ventilation decreases the temperature during sunny days and provides carbon dioxide, which is essential to the plants’ photosynthesis. A good air circulation is not just important in summer though. In winter, it prevents cold drafts on your plants and provides fresh air for growth. There are multiple options to provide the perfect ventilation.
