  2. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    The formulation of hydroponic solutions is an application of plant nutrition, with nutrient deficiency symptoms mirroring those found in traditional soil based agriculture. However, the underlying chemistry of hydroponic solutions can differ from soil chemistry in many significant ways. Important differences include:

  3. Ebb and flow hydroponics - Wikipedia

    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 ...

  4. Controlled-environment agriculture - Wikipedia

    en.wikipedia.org/wiki/Controlled-environment...

    In Asia, adoption of indoor agriculture has been driven by consumer demand for quality. [24] The Recirculating Farms Coalition is a US trade organization for hydroponic farmers. [25] A 2020 survey of indoor plant farming in the U.S. [26] found that indoor production was: 26% leafy greens, 20% herbs; 16% microgreens; 10% tomatoes; 28% other

  5. Vertical farming - Wikipedia

    en.wikipedia.org/wiki/Vertical_farming

    The term "vertical farming" was coined by Gilbert Ellis Bailey in 1915 in his book Vertical Farming.His use of the term differs from the current meaning—he wrote about farming with a special interest in soil origin, its nutrient content and the view of plant life as "vertical" life forms, specifically relating to their underground root structures. [16]

  6. Underground farming - Wikipedia

    en.wikipedia.org/wiki/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 ).

  7. Organic hydroponics - Wikipedia

    en.wikipedia.org/wiki/Organic_hydroponics

    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 ...

  8. Passive hydroponics - Wikipedia

    en.wikipedia.org/wiki/Passive_hydroponics

    Semi-Hydroponics (Semi-Hydro or S/H) was the first passive hydroponic technique utilized for orchids, originating in the early 1990s, using Lightweight Expanded Clay Aggregate (LECA) as a medium in solid-bottomed containers, into which one or two, small-diameter holes were placed in the sidewall, setting the depth of the internal reservoir.

  9. Aeroponics - Wikipedia

    en.wikipedia.org/wiki/Aeroponics

    Although initially developed for NASA, ODC is not limited to space applications. Soil and hydroponics growers can also incorporate ODC into their planting techniques, as it complies with USDA NOP standards for organic farming. One notable example of ODC's expansion in agriculture is its application in the cannabis industry. The ODC product line ...
