The Auto Vent Opener helps control temp & humidity, providing venting as needed. It opens when the air inside warms, then closes when it cools. Its metal cylinder filled with wax expands when heated, pushing a piston that raises the window. No electricity is required; install it on the roof vent window and it starts working. Compatible with all Rion greenhouses. Opens at 12-15 Celsius (53.6-59 F); easy to install.


  • Opens roof vent automatically as temperature warms for air circulation and heat relief,
    closes when the temperature cools.
  • Solar powered, heat activated – start opening point: 12°-15° C
  • Mechanic system – no electricity is needed.
  • Suitable for all Palram–Canopia greenhouses with roof vents.
  • Easy to install.
  • For Rion by Palram-Canopia Greenhouses (Ecogrow, Grand Gardener and Prestige) only.
