  2. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Hydroponics is a method for growing plants in a water-nutrient solution without using nutrient-rich soil or substrates. Researchers and home gardeners can grow their plants in a controlled environment. The most common artificial nutrient solution is the Hoagland solution, developed by D. R. Hoagland

  3. Ebb and flow hydroponics - Wikipedia

    en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

    Detail of an ebb-and-flow system, nutrient-rich water is pumped through the hoses connecting the containers. 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 ...

  4. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Hydroponic cultures lead to highest biomass and protein production compared to other growth substrates, of plants cultivated in the same environmental conditions and supplied with equal amounts of nutrients. [11] Hydroponics is not only used on earth, but has also proven itself in plant production experiments in earth orbit. [12]

  5. Hoagland solution - Wikipedia

    en.wikipedia.org/wiki/Hoagland_solution

    The Hoagland solution is a hydroponic nutrient solution that was newly developed by Hoagland and Snyder in 1933, [1] modified by Hoagland and Arnon in 1938, [2] and revised by Arnon in 1950. [3] It is one of the most popular standard solution compositions for growing plants , in the scientific world at least, with more than 20,000 citations ...

    CEA technologies include hydroponics, aeroponics, aquaculture, and aquaponics. [2] Different techniques are available for growing food in controlled environment agriculture. Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment ...

  7. 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]

  8. 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 as channels.

  9. Deep water culture - Wikipedia

    en.wikipedia.org/wiki/Deep_water_culture

    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 one foot deep filled with a nutrient-rich solution with ...
