The Greenhouse design

The unique greenhouse design combination of these seven features makes the Growing Dome® the most advanced greenhouse kit design in the world

1. High Quality Glazing

The high quality POLYCARBONATE GLAZING is a clear, rigid translucent covering that allows 65% to 85% light transmission. It resists breakdown by ultraviolet light and harsh weather impacts, like hail. Life expectancy is over 20 years and both glazing densities 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!

The 8mm double wall glazing STANDARD carries an R value of 1.8, whereas the 16mm 5 wall or PREMIUM glazing is rated R 3.2 and is recommended for domes above 7000 feet altitude.

2. North Wall Insulation

This helps keep the Dome cozy during the long winter nights and reflects light evenly onto the plants for maximum growth. Provides shade in the summer and in combination with the water tank, helps prevent overheating, a unique greenhouse design feature.

3. Automatic Opening Window Vents design of greenhouse window opener

Solar powered actuators open the upper and lower vents at a preset temperature. Hot air escapes from the top of the Dome, creating a "chimney" effect, drawing in cold air through the lower vents, which prevents overheating. The window vents close automatically, freeing you to go on vacation without worry. The larger domes have solar powered or 110V cooling fans that are thermostatically controlled.

4. Water Tank

This unusual greenhouse design feature, a large water tank acts as the "Power Pack" of the Dome. The water mass keeps the Dome warm in the winter and cool in the summer creating optimum environment for year 'round growth. Can be used as a beautiful space for aquatic plants and for growing fish.

5. Undersoil Heating System

A solar panel produces electricity to power a fan which blows hot air through pipes buried in the raised soil beds. Every day when the sun shines, your soil is being heated. It also helps coll the greenhouse in the summer. 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 Dome sits on a foundation wall which raises the Dome up above the snow. This wall is insulated to prevent the soil in the growing beds from freezing.The wall is lined with sheet metal on the inside and has a bottom plate of pressure treated lumber for added longevity. Redwood or recycled plastic lumber options are available, also a termite proof wall.

7. Perimeter Insulation

Prevents frost from penetrating under the wall of the Dome. The entire soil mass maintains an even temperature, despite outside fluctuations. Most greenhouse designs omit this invaluable feature.
