Passive hydroponics , semi hydroponics or passive subirrigation , also sometimes referred to as hydroculture ref http hydro culture.net ref is a method of growing plants without soil , peat moss , or bark . Instead an inert porous medium transports water and fertilizer to the root s by capillary action . Water and fertilizer are held in a reservoir and conducted to the roots as necessary, reducing labor and providing a constant supply of water to the roots. In the simplest method, the pot sits in a shallow solution of fertilizer and water or on a capillary mat saturated with nutrient solution. Since Planned maintenance routine maintenance is much simplified, passive hydroponics can reduce the labor required to maintain a large collection of plants. The various hydroponic media available contain more air space than more traditional potting mixes, delivering increased oxygen to the roots. Allowing air to reach the roots is particularly important in preventing root rot in Epiphyte epiphytic plants such as Orchidaceae orchids and Bromeliaceae bromeliads , whose roots are exposed to the air in nature. Passive hydroponics also may add additional ambient humidity through evaporation. It is important in passive subirrigation to wash out the system from time to time to remove salt accumulation. Plants that require drying between waterings or a dry dormant period may fail to thrive under the constant moisture of passive hydroponics. Media Many media are available for passive hydroponics, but the most common are expanded clay pellets, coconut husk chips, perlite , vermiculite , Diatomaceous earth diatomite , charcoal , and rockwool . These are frequently used in combination. References references See also Hydroculture Hydroponics Gardening Category Hydroculture sv Semi hydroponic f r odling av orkid er ... more details
merge to Hydroponics date November 2011 Organic hydroponics uses organic fertilizer . Conventional hydroponics cannot use organic fertilizer because organic compounds contained in hydroponic solution inhibit the growth of the crop roots, so it uses only inorganic fertilizer. In organic hydroponics, organic fertilizer is degraded into inorganic nutrients by microorganisms in the hydroponic solution via ammonification and nitrification. The microorganisms are cultured with a method of multiple parallel mineralization . The culture solution can be used as the hydroponic solution. Practical method of organic hydroponics is developed in National Agriculture and Food Research Organization NARO , in Japan, in 2005 ref 1 ref . History of organic hydroponics Studies for establishing organic hydroponics have been conducted for long time. Kennedy Space Center had studied organic hydroponics for crop production in space ref 2 ref . It was necessary to develop the method to generate nitrate from organic fertilizer via ammonification and nitrification, because most of crops are nitrate phylic but not ammonium philic. It is easy to generate ammonium from organic fertilizer by saprophytic microorganisms. However it was difficult to degrade organic fertilizer to nitrate efficiently because the growth of nitrifying bacteria, such as the obligate chemolithoautotrophs Nitrosomonas spp. and Nitrospira spp., is particularly inhibited by the presence of organic compounds Jensen 1950 Quastel and Scholefield 1951 Rittenberg 1969 Smith and Hoare 1977 Krummel and Harms 1982 Takahashi et al. 1992 Stutte 1996 Xu et al. 2000 Tomiyama et al. 2001 .

Unreferenced date November 2006 Controlled environment agriculture CEA is any agricultural technology that enables the grower to manipulate a crop s environment to the desired conditions. CEA technologies include greenhouses greenhouse , hydroponics , aquaculture , and aquaponics . Controlled variables include temperature, humidity, pH, and nutrient analysis. In research, CEA is useful for isolating specific environmental variables for closer study. For example, researchers may study photosynthesis by comparing a crop from a greenhouse with special pane tinting with one that is not tinted. The advantage is that all other factors can be kept constant, reducing the incidence of another influence on the experiment. A February 2011 article in the magazine, Science Illustrated states, In commercial agriculture, CEA can increase efficiency, reduce pests and diseases, and save resources.... Replicating a conventional farm with computers and LED lights is expensive but proves cost efficient in the long run by producing up to 20 times as much high end, pesticidee free produce as a similar size plot of soil. Fourteen thousand square feet of closely monitored plants produce 15 million seedlings annually at the solar powered factory. Such factories will be necessary to meet urban China s rising demand for quality fruits and vegetables.

Notability date July 2008 An ultrasonic hydroponic fogger not to be confused with an aeroponic mister is a device that emits nutrient fog in a hydroponic system or terrarium to increase humidity. ref George F Van Patten. Hydroponic Basics. ref It usually sits below water level, and fills the root zone with fog, raising humidity in the rooting medium. Water particles are 5 15 micrometre s in size. The hanging roots absorb the water nutrient combination for accelerated growth in hydroponically grown plants. When combined together, turns a hydroponic system into an aeroponic hybrid system. An ultrasonic fogger is not an aeroponic mister. These are often confused. While foggers ultrasonically create fog also used in hydroponics to raise humidity , the aeroponic mister atomizes water into a nutrient rich mist by either dripping the water on to a spinning plate or a by using special gardening tip on a pvc tube. The mist is 100 oxygen rich along with the benefits of maintaining 100 humidity, providing the entire plant system with an aerated hence aero ponic root medium. This technique speeds growth significantly. It also assists with nutrient absorption. bi .dcj References Reflist Category Hydroponics agriculture stub ... more details
A water chiller ref George F Van Patten. Hydroponic Basics. ref is a mechanical device used to facilitate heat exchange from water to a refrigerant in a closed loop system. The refrigerant is then pumped to a location where the waste heat is transferred to the atmosphere . In hydroponics , pumps, lights and ambient heat can warm the reservoir water temperatures, leading to plant root and health problems. For ideal plant health, a chiller can be used to lower the water temperature below ambient level 68 F 20 C is a good temperature for most plants. This results in healthy root production and efficient absorption of nutrients. In air conditioning , chilled water is often used to cool a building s air and equipment, especially in situations where many individual rooms must be controlled separately, such as a hotel. A chiller lowers water temperature to between 40 and 45 F before the water is pumped to the location to be cooled. ref name HOW http home.howstuffworks.com ac4.htm How Stuff Works How Air Conditioners Work Chilled water and Cooling tower AC Units ref See also Gardening Notes reflist Category Hydroponics Category Cooling technology Category Heating, ventilating, and air conditioning Category Mechanical engineering de Kaltwassersatz ... more details
