I saw this discussion that happened in Chicago during the James Beard Awards. Thought you might be interested too.
Interestingly, vertical farming was big in Chicago. Farmed Here started up inside the city. But, local regulations and all the hoops the Illinois and Chicago city government forced them to jump through made it impossible to make a profit here. Too bad. They merged. Looking back on it they said they’d setup outside the city if they did it here again.
