    en.wikipedia.org/wiki/Water_chiller

    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 ...

    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.

    Detail of an ebb-and-flow system, nutrient-rich water is pumped through the hoses connecting the containers. Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition ...

    en.wikipedia.org/wiki/Hydroponics

    Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [51] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...
