The various hydroponic media available, such as expanded clay and coconut husk, contain more air space than more traditional potting mixes, delivering increased oxygen to the roots, which is important in epiphytic plants such as orchids and bromeliads, whose roots are exposed to the air in nature. Additional advantages of passive hydroponics ...
Deep water culture has also been used by hobby growers. Net pots, plastic pots with netting to allow roots to grow through their surface, are filled with a hydroponic medium such as Hydroton or Rockwool to hold the base of the plant. In some cases net pots are not needed. For oxygenation of the hydroponic solution, an airstone is added.
Underground farming. Underground farming is the practice of cultivating food underground. Underground farming is usually done using hydroponics, aeroponics or air-dynaponics systems or container gardens. Light is generally provided by means of growth lamps [1] or daylighting systems (as light tubes). [2]
Gary Blake, who served for more than 23 years as a jet engine mechanic, uses his Air Force training as an instructor in Wind Energy Technology. "When teaching and demonstrating hydraulics, it is ...
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required.

Rich development of surface roots. The Kratky Method is a specialized passive hydroponic technique which involves plants suspended in net pots above a non-circulating water and nutrient reservoir. The various hydroponic media available contain more air space than more traditional potting mixes, delivering increased oxygen to the roots.
Vertical farming. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1] Some common choices of structures to house ...
Organic hydroponics is a hydroponics culture system based on organic agriculture concepts that does not use synthetic inputs such as fertilizers or pesticides. In organic hydroponics, nutrient solutions are derived from plant and animal material or naturally mined substances. [1] Most studies on the topic have focused on the use of organic ...
