Abstract
A plant growth system for a microgravity environment includes a root chamber configured to prevent liquid from escaping from the root chamber in the microgravity environment and to enable recovery of liquid from within the root chamber. In some embodiments, the root chamber may be configured to provide water and/or nutrients to the plants, via ebb/flow and/or spray delivery. In some embodiments, the root chamber includes a main body and a root/shoot interface coupled to the main body. The root/shoot interface can be configured to hold a plant having a root system extending outward from one side of the root/shoot interface into the root chamber and a chute system extending outward from another side of the root/shoot interface outside of the root chamber. The root/shoot interface may be configured to provide water and/or nutrients to the plants.
