“A study in Proceedings of the National Academy of Sciences examines the efficiency of vertical farming methods to grow wheat. Wheat accounts for about 20% of the calories and proteins in a typical human diet. However, yields are variable and depend on several factors, including soil quality and weather.
Vertical farming is a relatively new and emerging practice that involves growing crops in vertically stacked layers, with tightly controlled environmental conditions to optimise plant growth, alongside soilless farming techniques such as hydroponics, aquaponics, and aeroponics. First proposed in 1999, the concept has since grown into a $2bn industry and is predicted to expand more than six-fold by 2026…”
