25′ x 50′ Long Dome Tunnel

KingDome 25′ x 50′ Long Dome Tunnel Greenhouse

Looking for an extra-long greenhouse? The KingDome 25′ x 50′ Long Dome Tunnel moves the geodesic dome form into another direction. Two domed ends meet in a stretched-out tunnel configuration. The unique footprint creates 1,250 square feet of interior growing space with an orderly rectangular layout more akin to hoop houses or gutter-connected ranges, while maintaining the triangular framework and structural benefits of a geodesic greenhouse. Priced at $22,500, this greenhouse model from KingDome is ideal for serious hobbyists and homesteaders as well as small farms and commercial growers that require elongated space for planting rows, raised bed gardens, or working aisles instead of rounded floor plans. Financing options are available through Acorn. Kits can be installed by yourself, with supervisor assistance, or with an entire professional crew from KingDome.

What Is the 25′ x 50′ Long Dome Tunnel?

The 25′ x 50′ Long Dome Tunnel is just what it sounds like: a cross between a geodesic greenhouse and a traditional tunnel-style hoop house. Dome-shaped structures cap both ends of this stretched-out tunnel, lending their slightly rounded footprint to a frame based on connecting rows of triangles. Built on wood framing with triangular supports and covering options similar to KingDome’s standard domes, this hybrid gives growers the ease of mapping out beds and aisles in straight rows inside a geodesic tunnel.

Specifications

• Dimensions: 25 Feet Wide x 50 Feet Long
• Floor Area: 1,250 Square Feet of growing space
• Structure: Elongated Dome Tunnel (triangular geodesic frames with a tunnel center)
• Estimated Retail Price: $22,500

Feature Highlights

• Elongated Dome-Tunnel Design: Instead of an expansive circle, this greenhouse stretches two geodesic frames into a tunnel-style center. The resulting row-friendly footprint works well next to property lines, buildings, and existing gardens or fields.
• 1,250 Square Feet Growing Space: Individual crop rows, garden beds, equipment working aisles, or tables and benches for starting plants can all fit comfortably inside.
• Geodesic Frame Design: Constructed with treated wood struts and foundational supports, standard and upgraded heavy-duty connectors are available.
• Covering Options: Choose from standard 12 mil interwoven reinforced polyethylene covering materials, add a supplemental layer to increase insulation, or select a rigid 3–5 mm dual-layer polyethylene covering called Solexx.
• Door Options: Like all KingDome models, this greenhouse offers multiple entry options. Select from a frequency entry door, a 36×80 nine-lite door, a 60×80 French door, or even a 96×84 garage-style door for larger equipment.
• Venting: Standard vents are included in every kit. Additional vent options can be found on KingDome’s Options page.

Benefits of the 25′ x 50′ Long Dome Tunnel

Like all dome-style greenhouses, geodesic engineering offers many benefits. Triangulated framework divides the supporting frame into hundreds of small triangles. Structural stress is evenly distributed through the frame, freeing growers to make use of the entire footprint. Rounded frames also resist large-scale environmental forces better than boxed shapes. Wind and heavy snow both slide easily off of a dome’s surface. Growers enjoy a pillar-free interior with high ceilings and lots of headroom. Combined with polycarbonate glazing options, sunny but uniform conditions are ideal for growing crops.

How Does a Long Dome Tunnel Compare to Other Greenhouse Styles?

A geodesic dome maximizes enclosed space and resists structural loads more effectively than boxed greenhouses. With the added bonus of tunnel-style row layout, the elongated design of KingDome’s Long Dome Tunnel could be exactly what you’re looking for.
