I got the idea from watching the marijuana dispensaries start to pop up across the country and given my line of work in the data center business I had an 'A-Ha' moment.
Grow pot in old data centers
There is adequate power
Raised floors could support water lines for irrigation
The temp and humidity are already controlled so the infrsastructure is there
The facilities are secure
The biggest expense would probably be putting in the right kind of lights
Maybe someone already of this and I am half as smart as they are. Either that or I just figured out a way to make use of the Federal Consolidation of Data Centers without having big empty facilities mothballed.
