In an aquaponics system fish effectively fertilize the plants, this creates a closed looped system where very little waste is generated and inputs are minimized. Aquaponics provides the advantage of being able to harvest and sell multiple crops. Contradictory views exist on the suitability and safety of RAS effluents to sustain plant growth ...
Research concerning aquaponics has focused mainly on technical facets, with a limited number of studies addressing its economic viability, particularly in commercial contexts. While aquaponics is generally deemed profitable and sustainable, the calculation of costs and the comparison of systems are rendered complex due to diverse site ...
Comprehensive instrumentation and sensor controls are required to monitor this equipment and the underlying water conditions such as temperature, dissolved oxygen, and pH. Development of recirculating aquaculture systems is still underway in 2017, and engineering advances are needed to make the systems economically viable for culturing most ...
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.

Lettuce grown in indoor vertical farming system. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1]
The most important factor to consider when selecting a site for a raceway farm is the water supply. Water sources for raceway aquaculture operations are usually streams, springs, reservoirs or deep wells.
An example of deep water culture in lettuce production. Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water.
Plants commonly grown hydroponically include tomatoes, peppers, cucumbers, strawberries, lettuces, and cannabis, usually for commercial use, as well as Arabidopsis thaliana, which serves as a model organism in plant science and genetics. [8] Hydroponics offers many advantages, notably a decrease in water usage in agriculture.
