Vertical farming refers to a type of indoor agriculture wherein the plants are grown in vertical layers. They could also be piled horizontally or in three-dimensional contours. Some of the plants produced through vertical farming include leafy greens, vining plants, and herbs. The majority of this conventionally grown produce is sprayed with pesticides and fungicides. Moreover, they are farmed with extreme hygiene, are pesticide-free, and delivered for direct retail within hours of harvest.
