Benefits

The extra foot on our largest backyard greenhouse creates 314 square feet for growing. Many backyard gardens are smaller and won’t allow you to grow as much food. When designing your homestead or backyard garden, it’s important to maximize your growing space. Growing more food in a small area is beneficial because you make better use of the land you already have. This kit comes with versatile covering options allowing you to customize based on your growing conditions and preferences. In addition, DIY installation allows the homeowner to keep costs lower if they want to take on the assembly process. Should you desire, you can also hire a supervisor to manage your crew or hire KingDome to send a crew to do the work for you. Finally, the compact 20-foot diameter still works on many residential lots and creates enough growing space to support consistent harvests for a family of 3 or 4.

3 Reasons to Choose a Geodesic Dome Greenhouse

Should you wonder why you would pick a geodesic dome greenhouse versus a traditional greenhouse, there are actually many benefits:

• Load Distribution: They are comprised of interconnected triangles. When forces such as snow or wind push on the dome, they are distributed evenly through the arch. This allows the curved structure to support natural airflow and maximize light penetration from various angles throughout the day. This design tends to create more even growing conditions when compared to traditional rectangular-shaped greenhouses.
• Structural Efficiency: Because they use triangles in the design, you get structural strength and stability without unnecessary materials or complex designs.
• Space Optimization: Maximizes interior volume and headroom without increasing the overall footprint.

Growing

Because this greenhouse is ideal for those growing in their backyard, it can be used for backyard gardening, homesteading, and small household growing operations. This greenhouse will allow you to grow enough fresh produce to feed between 3 and 4 people. While not limited to these applications, they are perfect for those looking to grow their own food at home. Off-grid applications and education also work well with this kit (when coupled with proper site prep).

Installation & DIY Options

You have the option to assemble this KingDome greenhouse yourself. If you don’t want to DIY but still want control of the project, you can hire a supervisor to direct your crew. We can also send a crew to do the installation for you. Architectural drawings are available for this greenhouse should you require them for permitting (Additional Cost). Weather will play a factor in the installation of your covering. Please refer to our Installations page for current estimates and requirements.

Please note: If you plan to have this greenhouse shipped to you, you will need to purchase the 2×4×120 board used for the top of the door locally. (Our shipping crate is not long enough to accommodate that board.) This only applies to the 2V model.

Greenhouse Covering Options

Standard kit includes the industry-standard 12 mil interwoven reinforced polyethylene covering. Upgrade to a second layer of 12 mil IRP or upgrade to the hard-surfaced 3-5 mm Solexx polyethylene. Please visit the Options page for more information on each covering.

Who Should Consider Purchasing this Greenhouse Kit?

If you are a home gardener, homesteader, or small-scale grower looking for around 300 square feet of growing space, you should consider this greenhouse. It is also a great option if you would like to do the assembly yourself or want the option of professional installation.

How Do I Choose What Size Greenhouse I Need?

Ultimately, the size of your greenhouse will come down to how much space you have in your yard. How many people do you want to grow food for? What will you grow? Do you wish to DIY or have professionals install your greenhouse? All these questions should be considered when trying to figure out what size greenhouse will work best for you. This model is a great medium between a large footprint and growing capacity. If you find your needs may increase in the future, we have larger greenhouses available.
