It is possible to farm it in 100% seawater and directly connect its cultivation system to an aquaculture system for a wide range of fish species. [2] Common ice plant is known to accumulate high levels of heavy metals when grown in soil. This new system enables the farming of safe-to-eat organic ice plant by removing it from this environment.

Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma , but floating leaves and finely dissected leaves are also common.
This algae, also known as Red grass plant, has been available in the aquarium trade for a long time. Since it originates from deep water, it remains easy to care for, even without strong lighting. The algae radiates outward as it grows and will form dense fronds under good water quality and moderate lighting. [179] 5 in (12.7 cm) [179]
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.
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55] Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems.
