Example of a small hydroponic system for cannabis cultivation. Hydroponic cultivation generally occurs in greenhouses or indoors, although there is no practical obstacle to growing outdoors. In general, it consists of a non-soil medium exposed to a nutrient and water flow. These two cannabis plants are being grown in a DWC (deep water culture ...
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.

Inside an ebb-and-flow hydroponic system employing individual buckets connected by fill/drain hoses. The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. As a result of his work, water culture became a popular research ...
[it] markets itself [to them] using language that's in line with the free-spirited, artisanal cannabis farmer." [3] The business made its first cannabis-related investment in April 2015, when it bought General Hydroponics, a 35-year old liquid nutrient maker, called by High Times "the standard for hydroponic growers".

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 to the plants but which anchors the roots and functions as a temporary reserve of water and solvent mineral ...

And much of the soil resides in a planter in the backyard, next to her son’s favorite hammock chair. “Every time that rose bush blooms, you watch it with such anticipation,” Muckenhoupt said ...
Researchers have utilized aeroponics to study the impact of gas composition in the root zone on plant performance. Soffer and Burger (1988) conducted a study on the effects of dissolved oxygen concentrations in a system they termed "aero-hydroponics," which involved a 3-tier hydro and aero system with distinct zones within the root area.
