Unlocking the Secrets of Underground Greenhouses
Are you looking to maximize garden productivity all year? Underground greenhouses, or walipinis, offer a practical solution. By harnessing the earth's natural insulation, they create stable temperatures for growing in almost any climate. Any size of our greenhouses work for this style.
Why Choose a Walipini Greenhouse?
Energy Efficiency: Walipinis require minimal artificial heating and cooling due to the soil’s insulating effect.
Year-Round Growing: Perfect for regions with cold winters, walipinis help gardeners maintain ideal temperatures throughout the seasons.
Water Efficiency: Paired with water tanks or rainwater collection systems, they make sustainable gardening possible, even in drier climates.
Location: If you have a hill that your greenhouse can be built into, we highly recommend a walipini style. Any amount of depth into the earth is beneficial, though 4-5ft is standard.
Cedar Built Greenhouses' Even-Span Roof: Why It's Ideal for Walipinis
Choosing the right roof style is essential, and Cedar Built's even-span roof offers several advantages over traditional slanted or arched designs:
Optimal Light Distribution: Sunlight reaches all corners of your greenhouse, ensuring even plant growth. Simple slanted roof designs must be placed perfectly to get the right amount of sunlight.
Structural Integrity: The even-span roof is highly durable, designed to withstand weather extremes—from snow in winter to intense summer heat. See our client’s experiences with our extremely weather resistant design here.
Key Elements for a Successful Underground Greenhouse
Orientation for Sunlight: In the Northern Hemisphere, a south-facing orientation provides maximum sunlight, essential for year-round growth; though we recommend tracking the sun during it’s lowest point during the winter solstice for the most accurate placement of your greenhouse. Ensure the light will hit the masonry blocks.
Temperature Control and Insulation: Our double-pane polycarbonate panels further enhances thermal efficiency.
Ventilation Systems: Walipinis can become humid and overly warm, similar to root cellars, without adequate ventilation. Our even-span roofs are designed with customizable venting options, including roof windows and solar fans, helping regulate temperature and humidity. These features can be lifesavers on warm days or in high humidity. Explore our greenhouse options for more details.
Water Conservation: Add water tanks or rainwater collection systems for eco-friendly irrigation. The straight eave walls of our greenhouses make it easy to attach a gutter.
