    "problem_addressed": "Limited arable space, high water and nutrient consumption of traditional soil farming, and the need for high-density urban food production.",
    "concept_summary": "A modular aeroponic system that places seeds on a micro-fleece cloth within a growth chamber, supplies misted nutrient solution to the root zone, and controls temperature, humidity, CO_2 and light spectra. Chambers can be stacked or placed side-by-side to maximize space, and the system includes mechanisms for cleaning the cloth, monitoring plant growth, and adjusting fluid flow.",
