  2. Root rot - Wikipedia

    en.wikipedia.org/wiki/Root_rot

    Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...

  3. Ebb and flow hydroponics - Wikipedia

    en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

    The high oxygen content of water filmed in this way suppresses most harmful lifeforms, keeping the root zones disease free. In other types of hydroponics this function must be performed by cooling the solution to protect it from pythium, a form of water mold responsible for a condition called "root rot", in which the outer cells of the roots ...

  4. Pythium - Wikipedia

    en.wikipedia.org/wiki/Pythium

    However, in hydroponic systems inside greenhouses, where extensive monocultures of plants are maintained in plant nutrient solution (containing nitrogen, potassium, phosphate, and micronutrients) that is continuously recirculated to the crop, Pythium spp. cause extensive and devastating root rot and is often difficult to prevent or control.

  5. Deep water culture - Wikipedia

    en.wikipedia.org/wiki/Deep_water_culture

    With proper management, a head of lettuce grown in ideal conditions in soil will grow as well as the same variety grown in a hydroponic system. [15] One advantage that DWC systems have over other forms of hydroponics is that plants may be re-spaced during the growth period, optimizing the growing area in regard to canopy cover and light-use. At ...

  6. 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.

  7. 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.

  8. Ultrasonic hydroponic fogger - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_hydroponic_fogger

    In a hydroponic system ultrasonic hydroponic foggers [1] 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 ...

  9. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems. [56] Rotary hydroponic systems should be avoided in most circumstances, mainly because of their experimental nature and their high costs for finding, buying, operating, and ...
