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.
We strongly recommend installing an even amount of roof ventilation windows so that you can place at least one on each side of the greenhouse.
Yes, Roof Ventilation windows work as an add-on and can be installed only once the greenhouse installation is complete.
