If you've ever tried hydroponic, you quickly realize that soil is amazing technology. Indoor ag is yet another utopian fantasy.

  Plenty of people are proving that wrong, with certain crops. I visited with some friends a couple of years ago who had leased a paddock to a pair of humans who used it to build a hydroponic green house. They produced leafy greens for the local restaurant market and in the first part year had more cash flow than the whole farm around them. They were working very hard but were poised to make a lot of money. They were using the sun for energy input - I fail to see how indoor agriculture under lights can be profitable except for the most valuable of crops

    It seems like vertical and hydroponics are great for leafy green cash crops and spices, but don't work well to produce cereals, soy, or pulses, which are materially where all of the calories come from.
