HARTSVILLE, Tenn. (AP) -- It's not to the Batcave -- but the pot cave.

Tennessee drug investigators say they've busted a pot growing operation in the Hartsville area that looks like something out of a Hollywood action movie.

According to prosecutors, the cave beneath a stylish A-frame home was equipped with sophisticated gear for lighting, irrigation and even humidity control.

The cave was reached by secret entrances from the house or through a tunnel big enough for a car.

Police say the underground pot farm could produce 100 pounds of high-quality weed every couple of months.

Tennessee authorities report arresting three suspects.
