A soil-less method of growing plants that uses nutrient solutions such as sand, gravel, and liquids to encourage a more efficient growth of plants than soil would. Growth occurs under human-controlled conditions which serve to minimise the space occupied by growing plants and its large root structures which is typical of soil-grown plants. Other benefits of this process may include:

• More flexible growth
  Plants may be grown all-year-round and are not bound to solely indoor or outdoor conditions – which, greatly benefits Bahrain given its desert-like environment and lack of rain that would usually limit the time frame under which certain crops may be grown. In fact, Bahrain’s arid environment encourages growth under hydroponic conditions
• Growth may be regulated and controlled
  The growing condition of the crops may be maintained or adjusted to the right level – as required by its environment
• Conserves more water than traditional plant growing
  The water is concentrated on one small area, providing a more focussed supply of nutrients needed for growth
• Eliminates soil borne pests providing healthier crops
  Since soil is excluded from this method of plant growth, there is a decreased need for pesticides
• Eliminates the need for plant fertilisers and thus leading to long term growth
