Regardless of the level of technology employed across their operations , there are a few key vertical farming techniques that are being adopted in an effort to solve one of the key problems facing modern agriculture : water wastage .
HYDROPONICS
The practice of growing plants without soil . Hydroponics uses a nutrient-rich liquid solution to submerge the roots of plants , which are placed in an inert medium ( gravel , sand , clay pellets ) for support . The method can drastically reduce water usage and increase yield .
AQUAPONICS
Adding an additional layer of sustainability to the hydroponic technique , aquaponics uses fish as the generators for the nitrate-rich plant food . Fish create ammonia-rich waste in their tank , the water from which is then pumped into an inert medium that contains plants . Bacteria in the bed turns
