This Halls Automatic Louvre Vent Opener will automatically open your louvre vents to allow cool air in to moderate the temperature inside your greenhouse, preventing excess humidity.

The autovent’s cylinder is filled with wax that liquefies as it heats up, automatically opening your louvre window vent and then closing it as the temperature drops later in the day.
