2. 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 ...

3. Hydroponics - Wikipedia

   en.wikipedia.org/wiki/Hydroponics

   The biggest advantage of top-fed deep water culture over standard deep water culture is increased growth during the first few weeks. [citation needed] With deep water culture, there is a time when the roots have not reached the water yet. With top-fed deep water culture, the roots get easy access to water from the beginning and will grow to the ...

4. Kratky method - Wikipedia

   en.wikipedia.org/wiki/Kratky_method

   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 ...

5. Aquaponics - Wikipedia

   en.wikipedia.org/wiki/Aquaponics

   The Deep Water Culture (DWC) system consists of substantial troughs containing perforated floating rafts, into which net plant pots are placed. Within the DWC system, these plant pots are typically filled with media, such as rockwool, coco, or pumice, that serve to support the roots, which are subsequently and continuously submerged within the ...

6. Nutrient film technique - Wikipedia

   en.wikipedia.org/wiki/Nutrient_film_technique

   Plants placed into nutrient-rich water channels in an NFT system. A home-built NFT hydroponic system. Nutrient film technique ( NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known ...

7. Historical hydroculture - Wikipedia

   en.wikipedia.org/wiki/Historical_hydroculture

   Historical hydroculture. This is a history of notable hydroculture phenomena. Ancient hydroculture proposed sites and modern revolutionary works are mentioned. Included in this history are all forms of aquatic and semi-aquatic based horticulture that focus on flora: aquatic gardening, semi-aquatic crop farming, hydroponics, aquaponics, passive ...

8. Aquaculture - Wikipedia

   en.wikipedia.org/wiki/Aquaculture

   t. e. Aquaculture (less commonly spelled aquiculture[ 1] ), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus ). Aquaculture involves cultivating freshwater, brackish water, and saltwater populations ...

9. Integrated Aqua-Vegeculture System - Wikipedia

   en.wikipedia.org/wiki/Integrated_Aqua-Vege...

   In a comparative trial with Deep Water Culture (DWC), the economic feasibility analysis indicated that the Integrated Aqua-Vegeculture System (iAVs) produced more crops with a wider variety at almost 20% less capital expenditure and operational expenditure costs. Sand beds are able to grow a greater variety of plants than the DWC system.
