The difference between hydroponics gardening and traditional soil gardening is that hydroponics uses no soil. Plants are suspended above a nutrient solution--water plus fertilizer--or anchored in some growing medium above the solution, allowing roots to feed from the liquid.
Hydroponics actually uses less water than soil gardening---up to 90 percent less--because hydroponic designs typically recycle the water.
Hydroponics gardening relies on fertilizer added to the water, because no soil is available to provide nutrients; therefore, hydroponics requires chemicals, while you can enrich soil with organic matter.
Hydroponic gardens rely on gardeners to control the amount of the nutrients, ensure the pH is correct and ensure the roots don't dry out. In short, hydroponic gardens need more attention than soil gardens.
Hydroponics can produce anything a soil garden can, but growers have to supply things that soil gardeners take for granted, like light and a growing medium to replace soil.
Soil gardeners must make do with whatever outdoor environment they have. Hydroponics frees gardeners to grow crops whether they live in the desert or tundra.
