This stuff is amazing and I love the initiative - but can these farms produce the amount a store needs? I always think about how cool it would be to have a salad restaurant where the walls were all vertical farming walls and all the seating had little vertical farms around them. Much like when you go to five-guys you see bags of potatoes everywhere. I figured the reason it didn't exist yet was the fact that vertical farms couldn't support a restaurant's needs.
