How much ventilation does a small Greenhouse need?

Ventilation is crucial to controlling the temperature and managing humidity levels inside your small Greenhouse. By having a good amount of Greenhouse ventilation, you provide your plants with the nourishment they require to survive.


The easiest way to ventilate small or mini Greenhouses is by having roof or side vents that provide regular cooling air changes throughout. This is known as natural ventilation.


Mechanical ventilation involves using fans or other devices to ensure the air is kept circulating throughout your Greenhouse.


The standard rule is, for every 50 sq ft of floor area, you should aim to have ten sq ft of ventilation for your small or mini Greenhouse, whatever your method of choice.
