In 2017 the Advanced Plant Habitat was designed for ISS, which was a nearly self-sustaining plant growth system for that space station in low Earth orbit.[31] The system is installed in parallel with another plant grown system aboard the station, VEGGIE, and a major difference with that system is that APH is designed to need less upkeep by humans.[31] APH is supported by the Plant Habitat Avionics Real-Time Manager.[31] Some plants that were to be tested in APH include Dwarf Wheat and Arabidopsis..[31] In December 2017 hundreds of seeds were delivered to ISS for growth in the VEGGIE system.[32]
