Built correctly, it uses the earth’s natural insulation to create a stable growing environment all year round. Key things to consider when building a Walipini greenhouse: ✔️ Location matters Choose a spot with maximum sun exposure and good natural drainage. ✔️ Depth is critical The structure must reach below the frost line to benefit from stable ground temperatures. ✔️ Strong retaining walls Soil pressure is constant. Walls must be properly supported with wood, stone, or concrete. ✔️ Correct roof structure The roof should have a straight ridge, not a rounded one, to properly support polycarbonate panels and snow load. ✔️ Quality glazing Use durable, UV-resistant polycarbonate to let light in while retaining heat. ✔️ Ventilation is essential Even underground, fresh air circulation prevents excess humidity and mold. ✔️ Drainage and moisture control Water must never accumulate inside — proper drainage is non-negotiable. ✔️ Simple, functional interior layout Raised beds, gravel paths, and easy access make maintenance easier long-term. A well-built Walipini greenhouse can grow food year-round using minimal energy — proof that smart design often beats expensive technology. | Plants and gardening | Facebook
