Hydroponic gardening is an interesting method of growing plants that produce eatable food.

Hydroponics or hydroculture is a method of growing plants using mineral nutrient  solutions instead of soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlit, gravel or Rock wool. A variety of techniques exist.Refer to this BOOK for good instruction on how to build a system.  Researchers discovered in the 1800s that plants absorb essential mineral nutrients as inorganic  ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics, but some will do better than others. It is also very easy to do; the activity is often undertaken by very young children with such plants as watercress. Hydroponics is also a standard technique in biology research and teaching and a popular hobby.

 The earliest published work on growing terrestrial plants without soil was the 1627 book, Sylva Sylvarum by Sir Francis Bacon, although Bacon died in 1626. Water culture became a popular research technique. It was found that plants in less-pure water sources grew better than plants in distilled water. Mineral nutrient solutions for soilless culture of plants were first perfected in the 1860s. Growth of terrestrial plants without soil in mineral nutrient solutions was called solution culture. It quickly became a standard research and teaching technique and is still widely used today. Solution culture is now considered a type of hydroponics where there is no inert medium.

 It is worth noting that one of the early successes of hydroponics occurred on Wake Island, a rocky atoll in the Pacific Ocean used as a refueling stop for Pan American Airlines. Hydroponics was used there in the 1930s to grow vegetables for the passengers. Hydroponics was a necessity on Wake Island because there was no soil, and it was prohibitively expensive to airlift in fresh vegetables. In the 1960s, Allen Cooper of England developed the Nutrient Film Technique. The Land Pavilion at Walt Disney World's EPCOT Center opened in 1982 and prominently features a variety of hydroponic techniques. In recent decades, NASA  has done extensive hydroponic research for their Controlled Ecological  Life Support Systems.

Hydroponic gardening is an excellent process for confined areas where soil is not readily available. Basement or other sutable location will suffice.Hyproponic gardening can also be done out doors Hydroponic procedures are very simple to follow and produce wonderful results. The necessary equipment is readily available on the market through the internet.  Some special note has to be considered for the plants need to be supported with some sort of structure so the roots are exposed to the nutrient solution.  Hydroponic system needs to have a proper light source. Hydroponic Gardening can be done using organic techniques avoiding comercial pesticide and strong syntheic fertilizer. What you feed your plants determines how well your plant will grow. Nutrients and growth enhancers are available in liquid or powder form.  Hydroponic Gardening requires a degree of atmosphere control and water management. This is not to complicated when you simply think of a hot house growing environment.
