A cannabis producing company that makes CDB oil has bought the closed local mall in the city that I’m from and is going to use it to grow pot and make the oil there.
Yeah, pot growers have been doing “indoor farming” and going “vertical” for a long time, out of necessity to hide from the DEA.
However, their crops fetch a premium that can offset the costs of electricity for lights and AC, etc.
I’m not sure growing tomatoes or something would be cost efficient enough to get past the advantage regular farming has of free rain and free sunlight.
