Building a Solar-Heated Pit Greenhouse

A solar-heated pit greenhouse combines the energy-conserving features of the traditional pit greenhouse with newer techniques and materials used in standard heated greenhouses. The result is a simple, inexpensive structure that blends into its environment and needs little or no heat from any source other than the sun. Greg Stone's simple, illustrated, step-by-step instructions show you exactly how to design, site, and build your own solar-heated pit greenhouse from start to finish.
