I don't think you understand how indoor vertical farming works. In 1/8 of an acre you can produce an entire acre of crops, utilizing upwards of 99% less resources.
To boot, you don't even need tractors to harvest. You can just pull the entire tray yourself once the NFT solution's drained from the channel.
I can take 1/8th of an acre of land, and produce a full acre of wheatgrass in two weeks and harvest it myself with no mechanical methods required in less than a couple of hours.
