Complete Growing Dome kit with two polycarbonate glazing options:

Multi-wall (16mm) 22 ft.Classic Kit – ($38/sq. ft.) – $13,450
With 5-6 hours of sunlight per day, the twin-wall polycarbonate glazing keeps the Growing Dome 15-20 degrees F warmer than the outside temperatures while the Multi-wall stays 30 degrees F warmer. We recommend the twin-wall polycarbonate for locations in plant hardiness zone 8b or higher. You can use the USDA Plant Hardiness Zone Map to look up what zone you are in using your zip code.

This is what Growing Dome Owners are saying:“For me the Grow Dome in winter is my way to connect with the natural world, a place of solace where I can feel and smell the vibrancy of the living soil. To grow food in the winter is a way to enhance my appreciation for the environment.” EW – PA “Even though our plastic gutters had large holes in them from softball size hail, there was NO hail damage to our geodesic 22 foot Growing Dome greenhouse from Growing Spaces. We highly recommend the Growing Spaces to anyone interested in a solar greenhouse.” J E –WY “I celebrated the dome´s birthday yesterday Sunday 15 April 2012 with a glass of my favorite wine. It was the highlight of my life for the last 10 years.” UWS – OR
Windy Weather Package – $276
1. Do you live on a hilltop or ridge exposed to the prevailing wind?
2. Are there winds gusting to over 60 MPH in your location?
3. Do you live in a very windy area?
If you can answer “Yes” to any of these questions, then we highly recommend the Windy Weather Package for your 22 ft. Growing Dome greenhouse kit. This package for our small greenhouse adds sturdy Bayliss Hydraulicheck openers to all of the vents to prevent the openers and vents from being thrashed by strong winds.
Desert Heat Package – $500
1. Do you live in a desert or semi-desert climate (i.e. hot climate with low humidity)?
2. Do temperatures get above 95° F on a regular basis?
If you can answer “Yes” to any of these questions, then we highly recommend Desert Heat Package for your Growing Dome. This package for our small solar greenhouse kits adds a Solar Powered Cooling Fan for extra ventilation and cooling and utilizes the evaporative cooling effects of a full-surround Misting System that easily connects to your garden hose.
Solar Powered Waterfall – $290
The solar powered waterfall for the 15 ft. greenhouse kit provides aeration for the pond which the fish enjoy and helps to slow down algae formation. Even better, it creates a wonderful ambiance inside our year round greenhouses. View Growing Spaces video of our pond with a solar powered waterfall.
