  2. 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]

  3. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    The free and open source tools HydroBuddy [90] and HydroCal [91] have been created by professional chemists to help any hydroponics grower prepare their own nutrient solutions. The first program is available for Windows, Mac and Linux while the second one can be used through a simple JavaScript interface.

  4. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Hypoxia can affect the nutrient uptake of a plant because, without oxygen present, respiration becomes inhibited within the root cells. The nutrient film technique is a hydroponic technique in which the roots are not fully submerged. Incomplete submergence allows for adequate aeration of the roots, while a "film" thin layer of nutrient-rich ...

  5. 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 ...

    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.

  8. Justicia gendarussa - Wikipedia

    en.wikipedia.org/wiki/Justicia_gendarussa

    The hydroponic system is an alternative cultivation method for large-scale production. Explants of the J. gendarussa are placed in thermocole sheets and then put into water. The water contains a nutrient solution.

  9. 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.
