Greenhouse Ventilation
Greenhouse ventilation works together with shading, heating and damping-down to maintain greenhouse temperature and humidity. Ventilation is key in Alitex greenhouses. The unwritten rule is that a greenhouse should have ventilation equivalent to 17% of floor area.
Our greenhouse design uses vents in the roof and sides, which combined with steeply pitched roofs and low eaves, creates a chimney effect for optimum growing conditions.
While ventilation is unlikely to be an issue in winter, in summer an unmanaged greenhouse can quickly overheat, with disasterous consequences. On a hot summer’s day greenhouse ventilation on its own may not be much use – it can simply lower humidity, drying out and damaging your plants, and the outside temperature might be hotter than desired anyway. Under these circumstances greenhouse ventilation must be used in conjunction with shading to manage the greenhouse environment.
Ventilation is a vital factor in choosing the right greenhouse: a greenhouse without adequate ventilation is a waste of money. Even a small 7” by 11” greenhouse needs at least two large ventilation panels and even then, on some days, you might need to leave the door open.
Depending on your needs our designs can incorporate greenhouse ventilation systems ranging from simple, manual, glass vents to sophisticated climate control systems.
