The hydrophonics system is a key part of vertical farming. VFarm specifically uses the Nutrient Film Technique (NFT) where plants are grown in a soilless solution that is recycled from a reservoir. This provides hydration (water), oxygen and nutrients, which are normally found in soil, and are required for roots. Since in vertical farms the roots are uncovered and exposed to more oxygen, the crops will be able to grow at a faster rate.
