GEODESIC DOME STRUCTURE
Structural units of the geodesic Dome consist of Douglas Fir lumber, treated with an eco-friendly organic Wood Treatment, ready to fasten to strong aluminum connecting hubs. Our greenhouse kits come pre-cut, pre-drilled, and color coded. If you are semi-handy with a hammer, circular saw, and electric drill, you can choose to assemble sizes 22 feet diameter and under of dome yourself.
The geodesic dome structural members are warranted for 10 years.
The Dome wall is built from Douglas lumber studs, covered with Douglas siding, insulated with organic insulation (wood and hump fibers), and lined with galvanized metal flashing on the inside. Enjoy raised bed gardening in our garden greenhouses with the 24 inches (60cm) high foundation wall that comes with your kit. Each section of foundation wall comes pre-assembled and the number of sections of foundation wall depends on the diameter of the dome ordered.
There are 2 options :
Our greenhouses feature high quality polycarbonate glazing that is a clear translucent covering that allows 62% to 81% light transmission. Polycarbonate is a 16 mm glazing 5 wall, with R value of 3,0 This greenhouse covering resists breakdown by ultraviolet light and harsh weather impacts, like hail. The greenhouse polycarbonate glazing has a life expectancy of 15 to 30 years and comes with a 10-year warranty by the manufacturer against yellowing and hail damage.

The greenhouse polycarbonate glazing has a life expectancy of 15 to 30 years and comes with a 10-year warranty by the manufacturer against yellowing and hail damage.
THE FOLLOWING FEATURES ARE INCLUDED WITH THE GREENHOUSE DOME KIT
North wall insulation:
With our passive solar greenhouse kits, Reflectix® custom-cut insulation panels are provided to cover the northern 2/5ths of the Greenhouse Dome, acting as a blanket to cut down heat loss in the winter months and shading the above ground pond like an umbrella would during summer months. This keeps the Dome greenhouses warmer in the winter and cooler during summer. The reflective surface increases the available light inside the Domes.
Automatic greenhouse vent openers open and close the vents which prevent the geodesic greenhouses from overheating in summer. These openers are adjustable and work by the natural heating and cooling of a tube of compressed wax. The 26 feet Dome (7,9 m) comes with one thermostatically controlled, solar powered, 12V cooling vent fan. The larger Dome greenhouses 33 and 42 feet (10m et 12,5m) come standard with 240V cooling fans which require an electrical power supply.
Central air system:
In the central air system (also known as an undersoil heating and cooling system), a small fan draws air through pipes buried in the raised beds; making the air circulate from under the soil to inside of the dome. In winter, when the sun shines, your soil is being heated by the air coming from the dome, while in Summer fan brings fresh air from under the soil to inside the dome. The passive solar greenhouse kit contains the fan, distribution box, a solar panel to power the fan, and the pipes to be buried in the soil. The length of the pipes provided depends on the size of the dome ordered.
Above ground pond:
above ground pond: The main thermal mass of the passive solar Dome greenhouses is a large elliptical shaped above ground pond for the 15 feet (4,5m.) to 26 feet (7,9m.) Domes. Round ponds are standard for the two larger Dome greenhouses. Pre-drilled brackets, hardware, a pond liner sheet metal and lumber are provided in our geodesic greenhouse kits. The pond in the year-round greenhouse can be used as a water garden to grow aquatic plants and fish and is a critical feature of the Growing Dome’s passive solar design.
