These pictures are from a marijuana crop hidden in Tennessee. This grow was underneath a house in a secret cave. The entrance was through a secret hydraulic door in the garage that led to a concrete ramp that went about 50 yards into the ground leading to a cave. Inside the cave was living quarters and a secret escape hatch that led through a tunnel that exited via another hydraulic door that opened up a rock on the outside of the house. It is extremely elaborate set up that allowed them to harvest every 60 days, resulting in multi-million dollar sales.

Just imagine if these guys had put half as much effort into doing something legitimate!
