Importance of ventilation

Greenhouse ventilation is useful not only to reduce the inside temperature, but also to decrease the air damp and keep constant the CO2 concentration.
An high greenhouse requires a smaller number of air replacements – comparing with a low greenhouse – to obtain the same airing effect.
