18-Foot Growing Dome

Growing Domes offer many advantages over the conventional box-shape and traditional greenhouses. Made from high-quality materials including eco-friendly 16mm polycarbonate panels, each component of your dome is precisely measured and cut for one of our six sizes. As striking as they appear, the true beauty of these domes is in their innovative design and expert engineering!

High wind stability: Dome geometry and reinforced framing resist lateral loads and turbulent gusts. Able to withstand gale-force winds, and known to endure even against certain hurricane storm conditions.

Snow‑load capable: Triangulated structure transfers weight efficiently to ground, protecting the shell and doorway.

Hail‑resistant skin: 16 mm multi‑wall panels cushion impact and maintain light diffusion if scuffed.

Passive thermal control: High-volume air circulation and solar gain help maintain stable interior conditions during cold snaps or power outages.

UNDERSOIL UNIT

The Undersoil Ventilation System (UVS) utilizes the consistent temperature of the soil, taps into the thermal mass, stores, and releases that thermal energy into the dome.

SOLAR-POWERED FAN SYSTEM

The UVS utilizes an open-loop system, circulating air with two fans at 75 CFM (cubic feet per minute) powered by an external solar panel.

REFLECTIVE INSULATION

The North wall insulation covers about 1/3 of the polycarbonate glazing panels on the inside of the Growing Dome® all year long. The insulation reflects light and radiant energy away from the greenhouse, which provides shade for the Above Ground Pond in the summer, keeping the greenhouse cool. In the winter months, the insulation reflects the light and radiant energy from the sun towards the above-ground pond, keeping the water in the pond and the ambient air temperature in the greenhouse warm.

ALUMINUM SHADE CLOTH

The aluminum shade cloth reduces the amount of sunlight and heat transmitted into the greenhouse. Most Growing Dome owners put it up between April – June and take it down between September – October. The shade cloth reduces the amount of summer sun rays by 50% without depriving the plants of too much light.

ALUMINUM BRACKETS AND HARDWARE

• All Growing Domes come with a full hardware kit for installation

• Marine-grade, and corrosion-resistant

DRIP EDGE FLASHING

• Protects the 24″ all-weather wood foundation wall from water damage, rot, and mildew

Each dome sits on a 24” all-weather foundation wall made of wood composite siding, insulated with R-10 insulation, and lined with galvanized metal flashing. It can be primed and custom-painted for a unique, one-of-a-kind look.

The foundational wall is anchored to one of three foundation options: gravel ring, concrete pier, or insulated concrete forms (ICF).

During the installation process, Growing Dome panels are closed with a sealing tape, and each precisely cut panel creates a closed shell around the dome.

One of the final steps in your kit's assembly is applying a thick tape provided to you across the seams of the exterior panels. This adhesive is the same material used in the aerospace industry to provide an airtight seal to aircraft.
