Without proper air circulation, mold and mildew can grow on the items you store or grow in a ShelterLogic shed, garage, or greenhouse.
To keep your shelter or greenhouse cool and dry, you should install a ventilation system. A ShelterLogic vent is engineered to open and close automatically based on the interior temperature of your shelter or greenhouse. A heat-sensitive metal spring begins to open the vent at 74 degrees Fahrenheit, and fully opens when the temperature reaches 104 Fahrenheit. As the interior temperature goes down, the vent starts to close.
These vents are easy to install in any Shelterlogic fabric greenhouse or storage building.
