Urban gardening - Gardening without a garden and without soil! This handbook shows you how to grow vegetables even where real soil is either nonexistent or only available in small quantities. Innovative and easily implementable cultivation methods and systems, developed from hydroponics, permaculture, and organic farming, enable soil-less cultivation on balconies, terraces, or rooftops. Many graphics and images illustrate how cultivation and irrigation systems work. This way, you can grow and harvest vegetables in the city while conserving resources and saving space.
