Why do vertical farms use less water than greenhouses?
I can see why they'd use less water than outdoor farming - the water is lost to the atmosphere. But surely whatever mechanism a vertical farm uses for collecting and recycling water, a greenhouse could use too? Surely vertical farms are the same plants and growing methods in a greenhouse, but stacked?
