Airponics was the cultivation of plants without soil by suspending them in an oxygen-rich environment and misting their roots with a nutrient solution.
The Kantare created an airponics bay aboard their stranded ship. It was discovered by Commander Tucker and Sub-Commander T'Pol when they followed a shadow. In this airponics bay, Tucker first met Liana. Later, Liana offered Tucker a fruit from their airponics, the lorella. (ENT: "Oasis")
Kes established an airponics bay on USS Voyager along with a hydroponics bay to cultivate their own food supply. (VOY: "Parallax", "Elogium", "Cold Fire")
In 2372, the yields from Voyager's airponics lab were coming out low. (VOY: "Deadlock")
In 2375, Ensign Doug Bronowski worked in Voyager's airponics bay. (VOY: "Someone to Watch Over Me")
The vegetables in the airponics bay were beamed off the ship when Voyager entered the Void in 2377. (VOY: "The Void")
