I don't see a big difference between growing grass and growing marijuana, similarly corn. At least if it's grown outdoors without the help of artificial lighting. Have a look at the key crop: https://wiki.openstreetmap.org/wiki/Key:crop Well, besides that it is quite rare, mostly illegal with the exception of some fields operated for the pharmaceutical industry (the high THC concentration one). Then there's also kind of a comeback of hemp for fibre production (low THC concentration, legal in the EU). Vertical farming sounds interesting, but isn't something I've yet seen in the real. There have been some projects in Europe as well, but AFAIK have not been realized, see e.g. this one by dutch architects MVRDV: https://www.mvrdv.nl/projects/181-pig-city#/archive http://www.alternet.org/story/135410/high_rise_farms_the_new_model_for_sustainable_cities cheers, Martin
