Roof venting is still considered the best of greenhouse ventilation systems.

Natural ventilation or curtain ventilation uses a series of roof and sidewall vents.
Individually controlled roof vents in the greenhouse allow the intake of cool air to be a gentle flow to bench level not a strong force that suddenly lowers the temperature.
Access to the greenhouse is comfortable through a wide double door and the roof vent allows you to regulate temperatures humidity and airflow.
A roof vent serves as an escape route but it also provides a source of cool air intake.
