Aeroponics uses 98% less land and 95% less water than traditional farming methods. In aeroponics, plants can be grown very closely together with minimal risk of disease spread and without competing with each other for water and nutrients, many more plants per square foot can be sustained. Aeroponics is also easily adaptable to vertical setups, where multiple plant trays can be stacked up, multiplying the usable space well beyond the simple square footage of a room.
Aeroponics methods also use water with extreme efficiency. In traditional soil farming, rain or irrigation water falls indiscriminately over rows of crops. There may be too much or too little at any given time, but very soon the water has evaporated or flowed down the field into a nearby stream or ditch. In fact, irrigation systems that spray water long distances across fields can lose up to 35% of that volume simply due to wind and evaporation. In aeroponics, a fine mist of nutrient solution is provided at close intervals so that the plant is always able to absorb what it needs. In a well managed system, water waste is essentially zero.
