How Far Can Vertical Farming Go?
16th January 2023
While the technology shows much promise, the costs in both money and energy are still high. This means leafy salads, smaller vegetables and fruits such as tomatoes and strawberries – high value crops which grow quickly – are about the limit of what is currently available commercially from vertical farms.
But where exactly is the limit of what we can actually grow in a vertical farm? And if we did find a way to overcome the problems of cost and energy use, what would a world where all our food is grown in such farms look like? Could we ever move to completely soil-free farming?
