Note: Because the Growing Dome has much structural integrity, typically you can save the cost of pouring a concrete foundation. Also, Growing Domes are designed to be solar powered and operate off the grid, so you don't have to bring underground utilities into the greenhouse, thus reducing installation costs.
As you can see the Growing Dome offers more features than all the other greenhouses. It is also less expensive. It's the only greenhouse designed for year round energy efficient growing. So it's not just less expensive up front, it's less expensive to grow in year after year. How can we do this?
Our vision and commitment is to make the Growing Dome as affordable as possible. We use a combination of energy efficient materials, intelligent purchasing, low margins and overhead to make this the best greenhouse value for your money in the U.S. today.
We also did some research to find out how productive the Growing Dome is and how long it will take to pay for itself. With average gardening skills and productivity, the Growing Dome can produce 2.5 pounds of fresh food per square foot every year, offsetting the value of fresh organic produce against the initial cost of the Growing Dome.
The Growing Dome can return your
investment in full every 3 to 5 years.

Over its lifetime, you can realize your investment 5 times over, assuming proper care of the Growing Dome in the 15-20 year expected lifespan. The Growing Dome might well be the best investment you could ever make in terms of health, fresh produce, and value for your dollar.
