6 places where soil-less farming is revolutionizing how we grow food

If it seems like “hydroponic systems” are everywhere, that’s because they are. These are then absorbed, along with water, through a plant’s roots. Some systems even feed nutrients to plants through the air! From water-less deserts to the sun-less underground, soil-less farming is offering new possibilities to feed an increasingly urban, growing global population in a more Earth-friendly way. The mushrooms grow in a special medium and, through their respiration, provide valuable CO2 for the plants to thrive.
