Hydroponics

Hydroponics is a method of plant cultivation without the use of soil.

Instead, plants are grown by providing the roots with only the necessary mineral nutrients and water.

Plants may be grown in this "nutrient solution" alone or in conjunction with a variety of inert growing media.

The advantages of hydroponic growing are numerous.

Larger and more stable yields, lower water consumption, and reduced pollution from fertilizer runoff, are just a few.  Hydroponics also provides the opportunity for plant cultivation in environments where in-ground agriculture or gardening is simply not possible.
