Adequate oxygen (O 2) availability in the rhizosphere (root zone) is essential for promoting healthy plant growth. In aeroponics, where plants are grown in an environment of air and micro-droplets of water, almost any plant can thrive and reach maturity with an abundant supply of oxygen, water, and nutrients.
The water is released over the plant's roots and then runs back into the reservoir below in a constantly recirculating system. As with deep water culture, there is an airstone in the reservoir that pumps air into the water via a hose from outside the reservoir. The airstone helps add oxygen to the water.
The Lunar greenhouse is an underground farm made by Phil Sadles and Gene Giacomelli of the University of Arizona's Controlled Environment Agriculture Center (CEAC) [4] [5] The urine and exhaled air of the astronauts is reused in the system by the plants.

“Xeric air plants typically grow in drier climates,” says Raffaele Di Lallo, plant expert at Ohio Tropics and author of Houseplant Warrior: 7 Keys to Unlocking the Mystery of Houseplant Care ...
Air plants are growing rapidly in popularity as a low maintenance household plant. Due to their minimal root system and other adaptations, they generally do not require frequent watering, no more than four times a week, allowing the plant to completely dry before watering again.
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]
