Works on all Grandio Greenhouse roof vents.
This automatic vent opener gives you hands-free temperature control by automatically opening your roof vent when the greenhouse warms up and gently closing it as temperatures drop. No electricity or manual adjustments needed — just reliable, set-it-and-forget-it ventilation.
How it works: The opener contains a metal cylinder filled with a special mineral that expands when heated, pushing a piston to open the vent. As the temperature cools, the mineral contracts and a built-in spring smoothly closes the vent. This gradual operation provides exactly the right amount of airflow to prevent overheating while protecting your plants from sudden temperature swings.
