The design of our Growing Dome®, the most energy efficient greenhouse kit available, creates a solar powered greenhouse that allows for indoor gardening year round.
The greenhouse design creates a unique indoor growing environment for organic gardening. This is a greenhouse designed for both tropical and hardy plants. The geodesic dome greenhouse garden structure is made from polycarbonate glazing panels, is suitable for indoor gardening, and makes year round organic gardening possible in harsh climates.
The unique greenhouse design combination of these key features makes the Growing Dome® the most advanced greenhouse kit design in the world
1. High Quality Polycarbonate Glazing Panels
The high quality polycarbonate glazing panels are clear, rigid translucent covering that allows 62% light transmission. The 16mm, 5-wall polycarbonate glazing is rated R 3.0 and is rated as one of the premier greenhouse coverings available. It resists breakdown by ultraviolet light and harsh weather impacts, like hail. The life expectancy is over 20 years and the glazing panels come with a 10 year warranty by the manufacturer against yellowing and hail damage. You and your plants will love the soft diffused light inside!
2. North Wall Insulation (Reflectix)
The North Wall Insulation (also called "Reflectix") helps keep the Growing Dome cozy during the long winter nights and reflects light evenly onto the plants for maximum growth. It provides shade in the summer and, in combination with the water tank, helps prevent overheating. This is a unique greenhouse design feature. The outer surface of the triangles is white to help reflect excess heat in the summer.
3. Automatic Opening Window Vents
The automatic vent openers are heat activated and require no electricity to operate. The upper and lower vents open and close at an adjustable preset temperature due to the expansion and contraction of beeswax in a piston. Cooling of the Growing Dome is then achieved as hot air escapes from the top vents and cold air is drawn in through the lower vents. This creates a "chimney" effect and prevents overheating. The window vents open and close automatically, freeing you to go on vacation without worry.
4. Water Tank
This unusual greenhouse design feature, a large water tank, acts as the "Power Pack" of the Growing Dome. The water mass keeps the Growing Dome warm in the winter and cool in the summer creating optimum environment for year 'round growth. Can be used as a beautiful space both for aquatic plants and fish.

5. Undersoil Heating & Cooling System
A solar panel produces electricity to power a fan which blows the air in the dome through pipes buried in the perimeter raised soil beds. The air nearest to the intake, near the water tank, is warm in the winter and cool in the summer, so you are effectively heating or cooling your soil depending on the time of year. This system also helps circulate air through the Growing Dome and even out the overall temperature. This is a unique greenhouse design feature that makes year 'round growing a reality. Raised bed gardening is simple and easy on the back!
6. Insulated Foundation Wall
The Growing Dome sits on a 24" foundation wall which raises the Growing Dome up above the snow and gives increased headroom. This wall is insulated to prevent the soil in the growing beds from losing heat on a cold winter night.The wall is lined with sheet metal on the inside and has a bottom plate of ProWood treated or redwood lumber for added longevity.
7. Perimeter Insulation
A skirt of 2" blueboard insulation buried around the perimeter of the Growing Dome prevents frost from penetrating under the wall of the Growing Dome. The entire soil mass maintains an even temperature, despite outside fluctuations. Most greenhouse designs omit this invaluable feature.
