50′ x 100′ Long Dome Tunnel Greenhouse – Commercial Growing
It’s KingDome’s largest model: the 50′ x 100′ Long Dome Tunnel. Priced at $78,000, this stretched out geodesic greenhouse covers approximately 5,000 square feet of growing floor area, created by connecting two large domed ends with a tunnel-style mid-section. These systems enter commercial growing territory: vegetable farms, plant nurseries, educational facilities, and hobbyists ready to outgrow their backyard domes. While the footprint suggests a traditional gutter-connected series, the shell uses geodesic architecture rather than hoops or trusses. KingDome provides financing through Acorn, and offers owner, supervised, or full crew installation.
What exactly is the 50′ x 100′ Long Dome Tunnel?
At nearly 5,000 square feet, the 50′ x 100′ model stretches the geodesic concept into long tunnel territory. Rather than a circular floor plan, this system provides growers with a 50-foot by 100-foot indoor space with curved-end walls. Kits include framing, accessories, KingDome’s standard covering and door system (see company Options page), and ship crated from Missouri.

Features & Benefits of the 50′ x 100′ Long Dome Tunnel Greenhouse
Find more details on specific features below:
- Commercial Growing Space: At 5,000 square feet of growing room, the Long Dome Tunnel has plenty of space for a small market garden or commercial plant nursery.
- Minimal Frame Obstructions: Geodesic design results in an obstruction-free growing area with plenty of vertical headroom. The tall sides curve gently skyward rather than creating flat-wall vantage points.
- Multiple Building Options: Kit buyers can select an installation plan that includes an owner/build crew, KingDome supervised installation, or KingDome full crew installation.
- Financial Assistance: Acorn pre-approval is quick, and allows buyers to select an affordable payment plan.
Why buy a Geodesic Growing Space?
Energy efficiency, longevity, durability, and labor savings begin to enter the equation around this price point. Large geodesic domes use architectural efficiencies to save on initial cost and long-term operating expenses. By breaking the frame into small triangles, a geodesic shell can distribute loads throughout the entire building. Rounded walls also shed wind and snow better than most buildings. Additionally, sphere-shaped buildings enclose volume with less material than boxy structures. As a result, big domes maintain internal temperatures better than comparably sized rectangles. Since they don’t have center posts growing overshadowed, geodesic tunnels have plenty of vertical space and uniform light distribution.

Why choose geodesic when looking at greenhouses?Â
This size greenhouse starts to get expensive. Geodesic designs use architectural efficiencies to help offset the initial investment costs. Triangulated frames spread structural stress out through the building, and wind and weather flow around rather than against geodesic surfaces. You also don’t have to heat or cool as much empty space. Fewer seams mean less air infiltration and tiny gaps for insects to enter. Don’t forget that laminated dome kits resist deformation from snow loads and stay cool in the summer while offering taller crop headroom.
Available Sizes of Dome Tunnels
KingDome currently offers two styles of long tunnels:
- 50′ x 100′ Long Dome ($78,000): ~5,000 square feet, designed around commercial production.
- 25′ x 50′ Long Dome Tunnel ($22,500): ~1,250 square feet growing area for homesteads/small farms.
(Their domes come in sizes from 10′ to 60′ in diameter as well.)
Growing With a 50′ x 100′ Geodesic Greenhouse
Website descriptions list KingDome geodesic greenhouses as suitable for home, garden, farm, off-grid, commercial, and industrial applications. The long tunnel configuration works well for growing vegetables at high density, starting plants for nurseries, community and educational gardens, and commercial demonstration greenhouses.
People Ask For 50′ x 100′ Long Dome Tunnel
Do I have to install it myself?
No. While installation is not included in the price, you can elect to install the greenhouse yourself. If you choose not to DIY your greenhouse the alternative is to work with a KingDome install supervisor who coordinates a local crew. KingDome can also send a full crew if scheduling allows.
Can I apply for financing?
Yes. Financing through Acorn is possible and quick to pre-qualify for.
How big is it?
Around 5,000 square feet of growing space.
How much does it cost?
The $78,000 price is for the kit only. Delivery, assembly, and options like door style will cost extra.
