FAQs Sigma automatic ventilation window

The Sungrow Ventilation Windows will only be compatible with Sungrow Greenhouse models.

The Sungrow Ventilation Window is exactly 3 ft wide by 1.4 ft tall (91.4 cm by 42.6 cm).

The roof ventilation windows are made of the same material as your Planta Greenhouse: shatter-resistant polycarbonate and strong, galvanized steel.

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 plants that will be grown inside the greenhouse.
