This is how they grow it in Tennessee.This grow was underneath a house in a 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. Inside the cave was living quarters and a secret escape hatch that led you through a tunnel that exited via another hydraulic door that opened up a rock on the outside. It was very elaborate.The set up allowed them to harvest every 60 days which resulted in multi-million dollar sales.

Whoa. Definitely a must see. [via Boing Boing]
