Sometimes we are overwhelmed with the responsibility of managing everything in our lives. Greenhouse temperatures are no exception. An extra automated lower vent can be added to our 18′ dome for extra ventilation and peace of mind.
The sturdy Bayliss Hydraulicheck solar greenhouse vent openers are custom made in the UK for Growing Spaces, and are not available in retail stores. The Bayliss openers are perfect for our small to mid-sized greenhouse vents. The lower vents on the 18' and 26' Growing Domes are controlled by these openers. This solar greenhouse accessory offers a “hydraulicheck” feature that prevents the vent from being jerked open by strong winds. The solar greenhouse vent openers can be exposed to prevailing winds in excess of 60 mph. The Bayliss opens between 55-65 degrees Fahrenheit. Maximum opening distance of 12 inches.
