26 ft Growing Dome® Classic Kit

Our 26 ft. greenhouse kit includes


Complete Growing Dome kit with two polycarbonate glazing options:

Twin-wall (8mm) 26 ft.ClassicKit – ($30/sq. ft.) – $16,750

Multi-wall (16mm) 26 ft.Classic Kit – ($33/sq. ft.) – $18,250

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. (NOTE: 18 ft. greenhouse kits are produced with tip-taped triangles to serve our mission of being a low waste manufacturer.

Weather Packages

Desert Heat Package – $550

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.

System Upgrades

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.

Solar Attic Fan – $650

Replace the two top vents with one solar attic fan. Ideal for windy locations. The attic fan will also provide more ventilation than the standard top vents. 

Owner Supplied Items

The Growing Dome® is purchased as a greenhouse kit ready for assembly.

However, since a few items are bulky and costly to ship, and available at your local building supply store, they are not included in the greenhouse kit. Doing this lowers the overall cost for the Growing Dome owner.

See the Technical Specifications page for more information on Owner Supplied Items.


Growing Spaces delivers and/or ships within the United States and also ships Internationally.

Shipping / delivery, crating, and handling charges are not included in the price of the Growing Dome kit.

You may install the Growing Dome yourself (26′ Dome and smaller), hire a Growing Spaces Installation Supervisor to direct your crew, or you may choose to have our Full Crew install your Growing Dome kit.

To provide a seamless installation for the larger domes, 33′ kits require at least a Growing Spaces Certified Supervisor and the 42′ kit requires a Certified Supervisor plus one Growing Spaces crew member).

On a regular basis people consistently report how helpful it is to have someone trained and skilled at the build.
