Ventilator

Definition - What does Ventilator mean?

A ventilator in a greenhouse is a panel that is used to provide ventilation. It typically has hinges that allow it be opened and closed either naturally or mechanically.

Adequate ventilation is one of the most important aspects of growing crops within the confines of a greenhouse. A ventilator helps to regulate the greenhouse or grow room temperature, humidity, airflow, and oxygen. It also offers fresh air to the plants residing within the greenhouse, which helps prevent pest infestations and plant diseases such as fungal infections from occurring.

MaximumYield explains Ventilator

Ventilators should be located in the roof and the base of the greenhouse. Roof vents often feature solar openers that allow them to be opened and closed. A large vent in the roof lets excessive heat escape the greenhouse. Vents located near the base of the greenhouse provide cross ventilation.

Ideally, the ventilators should function by allowing air to flow through the vents near the base of the greenhouse. The air then blows across the plants, then the heated air rises and escapes through the vent in the roof of the greenhouse. Ventilators can be either natural or mechanical.

Natural ventilators rely on the wind and airflow to open and close, whereas mechanical ventilators operate by solar or electrical power such as fans to create air flow.
