Greenhouse Vent Openers
Growers Supply is your source for greenhouse vents! Greenhouse shutters, greenhouse vents and vent openers allow hot air to escape from a greenhouse while simultaneously allowing fresh air into the structure. This helps to not only keep temperatures moderate, but also provides a gentle breeze which helps promote good air circulation within the greenhouse. Automatic vent openers are a popular choice with many greenhouse growers because they are completely solar powered and do not require any electricity. When heat builds up within the cylinder mechanism the vent begins to open and later when the temperatures cool down the vent starts to close. This automatic process is ideal because gardeners do not have to worry about their plants overheating when they are not home to open the vent.
