Hydroponic?

Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk. (Wikopedia)

Advantages of hydroponic gardening are:

• • No soil is needed

  • The water stays in the system and can be reused - thus, lower water costs

  • It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs

  • No nutrition pollution is released into the environment because of the controlled system

  • Stable and high yields

  • Pests and diseases are easier to get rid of than in soil because of the container's mobility

Today, hydroponics is an established branch of agronomy. Rapid progress and results obtained in various countries have proved it to be thoroughly practical and to have very definite advantages over conventional methods of horticulture.
