About 'The Forest Garden Greenhouse- How to Design and Manage an Indoor Permaculture Oasis'

In this groundbreaking book, Jerome Osentowski, one of North America’s most accomplished permaculture designers, shows how to bring a forest garden indoors, even on unlikely terrain and in cold climates, using near-net-zero technology. The Forest Garden Greenhouse advocates a unique approach to indoor agriculture using permaculture design concepts that take season extension into new and important territory, whether you’re growing food or medicinals for your family or commercially.

Mr. Osentowski farms at 7200 feet on a steep, rocky hillside in Colorado. At this mountaintop site, he has been designing and building revolutionary greenhouses that utilize passive and active solar heat storage technologies via what they call the “climate battery.” This cutting-edge, subterranean air-circulation system pushes hot, moist, ambient air from the greenhouse during the day through a network of buried perforated tubes, storing heat and humidity in the soil, to be retrieved again during cold nights. This remarkable technology creates tropical and Mediterranean climates at high altitudes and in cold climates (and everywhere else). In addition to learning how to create their own climate battery, readers will receive in-depth information about: the fundamentals of design and construction of greenhouses of various sizes; capturing energy and ventilation; bed layout and soil building techniques; the secrets of successful companion planting; the use of microclimates within and around the greenhouse, and more.

About Jerome Osentowski
Mark Shepard

A forager and permaculturist with roots in rural Nebraska, Jerome Osentowski lives in a passive solar home he built at 7,200 feet above Colorado’s Roaring Fork Valley. Director and founder of Central Rocky Mountain Permaculture Institute and a permaculture designer for thirty years, he has built five greenhouses for himself and scores of others for private clients and public schools in the Rockies and beyond. He makes his living from an intensively cultivated one acre of indoor and outdoor forest garden and plant nursery, which he uses as a backdrop for intensive permaculture and greenhouse design courses. Among his accomplishments is hosting the longest-running Permaculture Design Course in the world, now at twenty-nine years running. Jerome and Michael have also been instrumental in identifying, conserving, and propagating heritage fruit trees that have survived and borne crops for over a century in the harsh environment of the Roaring Fork Valley. Jerome’s explorations of sustainable systems and his travels for development projects have taken him to Baja, Nicaragua, Patagonia, Finland, Australia, and the Caribbean.
