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.

Weather Packages

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.

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.

Owner Supplied Items

The Growing Dome® is purchased as a greenhouse kit ready for assembly by owner, contractor, or Growing Spaces crew (33′ kits require at least a Growing Spaces Certified Supervisor and the 42′ kit requires a Certified Supervisor plus one Growing Spaces crew member).

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.

See our Shipping page for more information on how to receive a quote. Local sales taxes do apply for customer pick-up.


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.
