“How does NASA grow plants suspended in the air?”

 

With the advent of hydroponics, the roots of plants have been liberated from the soil, allowing for far more sustainable agricultural systems to develop. One of these methods actually involves suspending the roots of the plant in the air and then filling the environment with a nutrient mist. Scientists have termed this process aeroponics, and allows for a higher density yield and allow for the roots to more efficiently absorb oxygen. However, one drawback is that this system must be constantly sprayed with a 35% hydrogen peroxide to prevent the spread of impinging fungi and bacteria. NASA uses aeroponic systems to grow food for astronauts on year long missions.
