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. [2]
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 ...
Containerized transplants or plugs allow separately grown plants to be transplanted with the roots and soil intact. Typically grown in peat pots (a pot made of compressed peat ), soil blocks (compressed blocks of soil), paper pots or multiple-cell containers such as plastic packs (four to twelve cells) or larger plug trays made of plastic or ...
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.
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .
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 ...
Close up of a Cannabis plant. Cannabis (/ˈkænəbɪs/) is commonly known as marijuana or hemp and has two known strains: Cannabis sativa and Cannabis indica, both of which produce chemicals to deter herbivory. The chemical composition includes specialized terpenes and cannabinoids, mainly tetrahydrocannabinol (THC), and cannabidiol (CBD ...
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
