Greenhouse ventilation Ventilation is one of the most important components in a successful greenhouse. If there is no proper ventilation, greenhouses and their plants become prone to a myriad of problems. Ventilation serves four major purposes within the greenhouse: •
Regulating the temperature
•
Ensurance of plenty of fresh air to photosynthesize
•
Good ventilation prevents pest infestations
•
Encouraging important pollination within the greenhouse
In greenhouses recirculation fans can be used in parallel or series ventilation.
