  2. Ultrasonic hydroponic fogger - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_hydroponic_fogger

    In a hydroponic system ultrasonic hydroponic foggers are used to create a fine mist, the individual particle size of which is typically of about 5 μm in diameter. These fine particles are capable of carrying nutrients from the standing water of a reservoir to plant roots. Benefits include humidification and exponentially improved root exposure ...

  3. 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.

  4. 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]

  5. 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.

  6. Aquaponics - Wikipedia

    en.wikipedia.org/wiki/Aquaponics

    A media-based grow bed is a hydroponic system type that utilizes a trough filled with an inert material to assist plant roots and accommodate beneficial microbes. Water is usually delivered in a flooding and draining cycle (ebb and flow), delivering nutrients and oxygen to the plants.

  7. Controlled-environment agriculture - Wikipedia

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

    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 ...

  8. 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 ...

  9. Ebb and flow hydroponics - Wikipedia

    en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

    The hydroponic solution alternately floods the system and is allowed to ebb away. A root ball and the growing medium required to grow a single plant. The medium will be washed and sanitized before being re-used. Under this system, water-tight growing containers are filled with a inert growing medium.
