An aeroponic root system comprises a plant cell having a first root chamber coupled to a second root chamber. A perforated divider may be disposed between the first root chamber and the second root chamber. In some examples, a fluid delivery system may convey water, nutrients, oxygen (e.g., purified oxygen gas), and/or carbon dioxide to the plant according to corresponding delivery schedules. For instance, water and oxygen may be conveyed into the first and second root chambers via a main supply line. Carbon dioxide may be conveyed to a base of the plant via a carbon dioxide delivery ring. In some instances, the delivery schedules may be determined by a type of the plant and/or a growth stage of the plant.
