Side Ventilation Windows

Can I add windows for my greenhouse later?

Roof ventilation windows work as an add-on and can be installed only once the greenhouse installation is complete. Windows can be added later as well.

How do the automatic side ventilation windows work?

Our Automatic Side Ventilation Windows do not require batteries or electricity. A heat-activated mechanism opens and closes the window once a specific temperature is reached.

How many side ventilation windows are recommended for the greenhouse?

It is strongly recommended to go with an even amount of roof ventilation windows. This is so you can place at least one on either side of the greenhouse. The amount of windows required depends on the greenhouse size, the climate you are in, and the types of crops that will be grown inside the greenhouse.

What are the opening and maximum opening temperatures for the Automatic Side Vents?
