PLANT A SEED and grow your own, all year long...in an inexpensive underground greenhouse known as a walipini. A walipini can be built at a cost of $250 - $300... or upwards from there if you'd like. A much more affordable and effective alternative to glass greenhouses, the walipini (an Aymara Indian word for a "place of warmth"), is also known as a pit greenhouse. Walipinis take advantage of the earth's constant temperature. At about 6 ft. below the surface, the soil temperature remains between 50-60 degrees F year round. Use recycled windows or plastic for the roof. Learn more and find directions below. Let's take back control of our food!
