  2. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [53] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...

  3. Deep water culture - Wikipedia

    en.wikipedia.org/wiki/Deep_water_culture

    An example of deep water culture in lettuce production. Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than ...

  4. Aquaponics - Wikipedia

    en.wikipedia.org/wiki/Aquaponics

    Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. [1][2] Plants are grown in hydroponics systems, with their roots immersed in ...

  5. Kratky method - Wikipedia

    en.wikipedia.org/wiki/Kratky_method

    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. [2]

  6. Vertical farming - Wikipedia

    en.wikipedia.org/wiki/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 vertical farming ...

  7. Ebb and flow hydroponics - Wikipedia

    en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

    Ebb and flow hydroponics. Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition to the plants but which anchors the roots and functions as a temporary reserve of ...
