The concept of soil-less gardening or hydroponics has been around for thousands of years. Consider the hanging gardens of Babylon, probably the earliest example of hydroponic gardening. In the 1970s, General Hydroponics (GH), the largest supplier of specialized chemical nutrients was born. NASA team up with GH and sent plants and nutrients to the international space station to study plant growth outside the earth's atmosphere, and how to best supply food and oxygen for future colonization missions in space. Dr. Franco Massantini pioneered the aeroponic method of hydroponic gardening. In the 1980s Dr. Hillel Soffer developed the aero-hydroponic method which helped transform the desert into an oasis of bounty. The Epcot Center at Disneyworld introduced "Living With The Land", a futuristic ride through hydroponic "gardens of tomorrow". Hydroponic gardening came of age in the 1990s when many more advances in soil-free growing were accomplished, including aeroponics and aquaponics. In aeroponics, a fine mist of nutrient solution is constantly sprayed onto roots for extremely vigorous growth. Aquaponics combines fish farming (aquaculture), and hydroponics by growing fish in a reservoir which in turn feed the plants with their excretions. Now, over a decade into the 21st century, there is concern over our food supply, our water supply and the diminished availability of land that can be used for agriculture. There will be incredible advances as hydroponic gardening continues to be an important consideration in agriculture. For a gardener, growing plants in a controlled setting is a blessing because it would mean better results, and may be even the best harvest ever!
