In a word no. I spent twenty years as a fertilizer agronomist and I'm very familiar with the costs of producing a crop.

The numbers simply do not work. Even when they tried in Detroit and got buildings for five cents on the dollar they couldn't make it work.

The investors funding these enterprises do not understand agricultural economics. I keep investigating these stories looking for some kind of 'breakthrough tech' that would dramatically reduce costs or increase yields. I've been tracking these vertical greenhouses for fifteen years, they open and a couple of years later they're gone.

I think what could change things for produce is solar cells and electric trucks. It would isolate producers transportation costs from oil prices and lower the cost of getting produce to the cities. I know technology is quickly improving in both battery technology and solar cells.
