An indoor-growing operation found in a Franklin County house led to the seizure of 39 pounds of processed marijuana and the arrests of a father and son, Sheriff Pat Melton said Monday.

The basement operation was discovered Sunday after a deputy responded to a call about a reckless driver near Creekside Lane southwest of Frankfort. A vehicle matching the description was found parked at 200 Creekside Lane. A strong odor of marijuana was coming from the house as the deputy approached, according to a news release.

That led to the discovery of marijuana grown hydroponically and 31 marijuana plants, Melton said.

"He had four high-pressure sodium light bulbs hooked up," Melton said. "It's not typical of what you see every day."

Kevin L. Barnett, 38, is charged with cultivating marijuana and trafficking in more than five pounds of marijuana over. His son, William N. Barnett, 18, was charged with cultivating marijuana.

Both were being held in the Franklin County jail.
