Unreferenced date January 2008 Image semi hydro33.jpg thumb 260px Cattleya transferred to passive hydroponics culture 5 weeks earlier. Rich development of surface roots. Passive hydroponics , semi hydroponics or passive subirrigation 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. See also Hydroponics Gardening Category Hydroponics sv Semi hydroponic f r odling av orkid er ... more details

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. In commercial agriculture, CEA can increase efficiency, reduce pests and diseases, and save resources.

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. 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 References Notes reflist Bibliography External links Category Hydroponics Category Cooling technology Category Building engineering Category Heating, ventilating, and air conditioning Category Mechanical engineering ... more details
