High-rise veg at a high cost

Every drop of water and nutrient will be recycled within these vertical greenhouses, with light and temperature optimised for plant development.

Farming goes urban on a big scale in the city of Linköping in Sweden, where the world’s first vertical greenhouse is being built.

It will use excess heating and carbon dioxide from nearby industries, and costs and environmental damage involved in transportation will be cut by delivering the leafy produce directly to the end users in urban areas. Funding comes from the Swedish government, among others.
