Created by a team of 8 engineers as part of our senior design capstone project. This is an open-source, semi-autonomous, DIY aeroponic plant-growing system, which enables users to build their own system and closely monitor growing conditions from their smartphone. This system uses a plant growing method called aeroponics, originally developed through NASA-sponsored research in the late 1990s to enable plants to grow onboard the ISS using no soil and very little water. In an aeroponic system, roots are suspended mid-air inside a chamber and are watered frequently with a fog-like mist and dissolved nutrients. This maximizes the plant's access to air, water, and other nutrients. Compared to traditional soil-based farming, aeroponic systems tend to grow plants many times faster than traditional farming and require less than 10% of the water. Aeroponics is one of many vertical farming technologies being developed to address some of the issues created by traditional farming methods, such as water scarcity, chemical runoff, topsoil degradation, long-distance transportation, and ecosystem disruption.
