Geodesic Dome Greenhouse Kits – Technology Improvements

Growing Spaces® is an innovative, sustainable greenhouse manufacturer. We value excellence and continue to develop any and all aspects of the geodesic Growing Dome® kit and its accessories. This makes the Growing Dome one of the premier greenhouse kits on the market today.

We have made numerous improvements to to our geodesic greenhouses over the 25 years we’ve been in business. These advancements have increased the longevity, efficiency, ease of use, and look of our Growing Dome design. Some of these upgrades are included in the Growing Dome greenhouse kit, and some have an upgrade fee. The Growing Dome greenhouse has stood its ground for 25 years!

Cost Effective Twin-Wall Polycarbonate Glazing Returns (released 2013)

In early 2012, we adopted the multi-wall greenhouse polycarbonate glazing as our main solar greenhouse covering because this option is what the majority of our customers were purchasing. What happened was our twin-wall polycarbonate glazing became close to invisible to the buyer, and customers in more mild climates or on a tighter budget were missing this valuable product. We brought the twin-wall polycarbonate glazing back to the fore in the fall of 2013 to offer more pricing options for our customers. Learn more about pricing of twin-wall versus multi-wall polycarbonate glazing.

Stronger Greenhouse Vent Openers (released 2013)

For years we have used the ultra-strong Bayliss Hydraulicheck solar greenhouse vent openers on our larger vents to help protect against wind damage, and we’ve found these custom-made openers to be far superior than what was available at the time. For especially windy areas and the vents on our largest two geodesic Growing Dome sizes we would place two Bayliss vent openers on each vent, and we found this to be a helpful option for many customers. Then we discovered a new product called the Gigavent Opener, that does the same work as two Bayliss openers, plus it opens the vents wider which allows for better airflow and cooling in the summer.

Snowshed Entryway Saves on Shoveling and Protects Your Head (released 2013)

We are the first geodesic greenhouse kit manufacturer to develop and offer the snowshed entryway. With the improved snowshed entryway, the snow that slides off the top of the Growing Dome is redirected out and away from the front of the greenhouse door eliminating the problem of a large pile of snow in front of your door. This roof also protects you from the danger of falling snow and ice as you come in and out of your solar greenhouse. Read more about our Greenhouse Door Snowshed Entryway

Safer Pro-Wood Bottom Plate (released 2013)

All Growing Spaces Growing Dome greenhouse kits come standard with a Pro-Wood treated Bottom Plate. Pro-wood is a much safer alternative to traditional pressure treated lumber and meets new building code standards. Here is more information from the manufacturer of Pro-Wood:
“Clean, odorless, non-staining and non-irritating, ProWood MCA (micronized copper azole) treated lumber is safe for humans, animals and the environment. The process we use to treat has gained Environmentally Preferable Product (EPP) status as certified by Scientific Certification Systems (SCS), a third-party certification services and standards development company. The preservative in ProWood MCA treated lumber has earned NAHB’s Green Approved Product certification (pdf – 633 KB) and the GREENGUARD Children & Schools Certification.”

For those of you concerned about any kind of wood treatment, we do have the option to go with a redwood bottom plate for your geodesic greenhouse instead. There are two important things to consider. If you live in an area with high humidity and/or termites, you will need to go with the Pro-wood bottom plate because it is more resistant to decay and termite damage than redwood. Also, if you are obtaining a building permit, you will likely need the Pro-Wood bottom plate to match the local building codes for your solar greenhouse.

Durable Smart Siding for the Foundation Wall (released 2012)

The 24″ foundation wall of our Growing Dome green houses are now all covered with Smart Siding. This superior product doesn’t chip or scratch. It is easier to drill than the HardiePanel cement board siding we used previously that required a special masonry bit. Smart Siding also helps protect against fungal decay and termites.

New Weather Packages (released 2012)

For years we interviewed hundreds of customers extensively to determine the weather conditions at their specific location and suggest which greenhouse vent openers, solar cooling fan options, and other add-ons were the best. After installing these options we tracked closely the performance of each add-on. Twenty-three years of experience doing this culminated in this year’s release of “Weather Packages”. Now with a few simple questions we can choose a package containing a prescribed number of solar greenhouse vent openers, solar cooling fans, etc. to match a given location. Learn more about Weather Packages by reading more on the details pages of each given size of Growing Dome greenhouse.

Shade Cloth Included in the Greenhouse Kit (released 2012)

The ability of our solar greenhouses to stay cool in the summer, while remaining off-grid, is increased automatically by the simple addition of a shade cloth. In the past, customers who didn’t purchase the shade cloth with their kit inevitably came back at the start of summer to order one. We decided the best thing to do was to include the shade cloth in the kit because we understand the value of this product in making summer gardening better. Currently, we are the only greenhouse manufacturer to include this in our kits. Read more about greenhouse shade cloths.

Eco-Friendly Lifetime Wood Treatment (released 2010)

Now, eco-friendly Lifetime Wood Treatment is used to treat the struts of our geodesic Growing Dome greenhouse kits. With Lifetime Wood Treatment, only one application is needed, ever! This treatment is completely safe, harmless, and contains no solvents or VOC’s (volatile organic compounds). Lifetime Wood Treatement is 100% water based, 100% non toxic, and non-flammable!

Less Maintenance with Metal Glazing Strips Upgrade (release 2008)

Our custom designed aluminum trim strips are applied to the outside seams of the Growing Dome solar greenhouse and eliminate the need to re-tape your greenhouse in 7-10 years. Rather than using the clear aircraft tape that comes standard with the Growing Dome greenhouse kit to seal the seams between the polycarbonate glazing panels, the Metal Glazing Strips Upgrade includes a long lasting tape covered by custom built aluminum strips to seal the seams. After 10+ years of use on our Growing Dome solar greenhouse kits we have found this upgrade provides a longer lasting, lower maintenance option for sealing. Inquire at 800-753-9333 for prices on maintenance kits for existing geodesic Growing Domes.

Multi-Wall and Twin-Wall Polycarbonate Options

Our Growing Dome solar greenhouse polycarbonate glazing is made in the USA! The multi-wall (16mm) polycarbonate glazing is standard and replaces the triple-wall and multi-wall polycarbonate glazing we offered in years past. Light transmission in to our geodesic greenhouses is diffused by the polycarbonate glazing and allows about 62% light transmission which people and plants love. For those that live in milder climates (hardiness zones 8b and higher) or for those whom price is a concern, we also offer a twin-wall (8mm) polycarbonate glazing. This has a 81% light transmission.
