The various hydroponic media available, such as expanded clay and coconut husk, contain more air space than more traditional potting mixes, delivering increased oxygen to the roots, which is important in epiphytic plants such as orchids and bromeliads, whose roots are exposed to the air in nature. Additional advantages of passive hydroponics ...
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. [1]
Underground farming. Underground farming is the practice of cultivating food underground. Underground farming is usually done using hydroponics, aeroponics or air-dynaponics systems or container gardens. Light is generally provided by means of growth lamps [1] or daylighting systems (as light tubes). [2]
Vertical farming. 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] Some common choices of structures to house ...
Hydroponics is an alternative to agriculture that creates the ideal environment for optimal growth without using a dormant medium. This innovative farming technique produces higher crop yields without compromising soil health. The most significant drawback of this sustainable farming technique is the cost associated with development. [178]
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. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with ...
