This download contains a PDF of the first 25 pages of Mike Oehler's The Earth Sheltered Solar Greenhouse Book.
The Earth-Sheltered Solar Greenhouse Book teaches you how to design and build a greenhouse that is six times more effective than the common greenhouse.
Most greenhouses rise up into the air where they lose heat at night and in the winter from four sides and the roof, while gaining heat from just the earthen floor.
The greenhouses described in this book overcome this problem; and the book explains how to build an earth sheltered greenhouse, using Mike Oehler's PSP building system, which will allow one to grow vegetables year round without supplemental heat.
