Farmers in Ohio basically plow empty, undeveloped land, plant seeds, use pesticides sometimes, and nature does the rest. They don't even irrigate, rain comes down from the sky and waters the crops.

The purchase price of farmland in Ohio is about $5000-6000 per acre.

You're talking about building a skyscraper as if crop production can generate enough revenue to justify that expense and somehow compete with all the other farmers who are just using the land as the found it a couple hundred years ago.

The cost to build a parking garage space is $20,000-$30,000 - and parking garages are just a slab of concrete. You'd still have to add in the costs of irrigation and artificially light the crops.

And then, how do you efficiently harvest vertical farms? Farmers in Ohio drive a giant vehicle over the generally flat and square field. How are you harvesting a vertical farm without huge labor costs in comparison?

There's actually nothing "green" about this vertical farm idea when you think about the extra power, concrete, and construction material requirement needed to realize it.
