In order to avoid excessive humidity, keep the temperature steady, encourage pollination and protect the plants from the effects of the weather, regular ventilation of the greenhouse is required.
The ventilation system of a greenhouse provides fresh air to the plants (CO2), helps to control temperature and humidity, and reduces the likelihood of disease.
Most greenhouse kits will come with roof vents already as part of the structure. They are simply vents at the ridge that will open and close either manually or automatically. The purpose of the roof vents is to allow warm air to escape. We all learned in school that warm air rises, so just open your roof vent and get rid of the unwanted heat. Roof vents should be closed in the winter when you want to keep your heat in the greenhouse.
