Description

The Vego Auto Vent Openers take temperature control off your to-do list. They mount to your greenhouse roof vents and open automatically when it gets warm inside — then close again when the temperature drops — without any electricity, batteries, or input from you.

Each opener uses a temperature-sensitive hydraulic cylinder that activates between 60 and 77°F. Dual springs push the vent open up to 18 inches for steady airflow on hot days, then pull it shut to hold warmth when it cools. The frame is powder-coated aluminum with stainless steel springs, so it holds up to greenhouse humidity over time.

Comes as a pack of two, so you can outfit two roof vents at once.
