  2. 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 ...

  3. 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]

  4. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Baked clay pellets are suitable for hydroponic systems in which all nutrients are carefully controlled in water solution. The clay pellets are inert, pH-neutral, and do not contain any nutrient value. The clay is formed into round pellets and fired in rotary kilns at 1,200 °C (2,190 °F). This causes the clay to expand, like popcorn, and ...

    en.wikipedia.org/wiki/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 water and solvent mineral ...

    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 ...

  7. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    The root, especially the root hair, a unique cell, is the essential organ for the uptake of nutrients. The structure and architecture of the root can alter the rate of nutrient uptake. Nutrient ions are transported to the center of the root, the stele, in order for the nutrients to reach the conducting tissues, xylem and phloem. [6]

    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.
