Federal and state drug charges are pending against two men after Izard County authorities raided property near Oxford Sept. 4.
A sophisticated marijuana growing operation, which included automatic watering systems and environmental controls, was discovered inside a building by law officers, said Izard County Sheriff Tate Lawrence.
Charges are expected to be filed against Stanley Sand, 50, who owns the property, and Roy Leonard Glisson, 49, who lives in one of the buildings that was raided.
"This is definitely the most sophisticated indoor grow operation I've seen," Lawrence said.
About 300 "grow stations" containing marijuana plants were found by officers, Lawrence said. He said the operation could have produced "hundreds of thousands of dollars worth of marijuana a year."
Two other structures on the same property had components to make more grow stations, but they were not in operation, the sheriff said.
Glisson lived in one of these structures with his mother, according to officials.
Plants, quantities of marijuana and other drug paraphernalia were taken from the site, according to the Izard County Sheriff's Department.
The Drug Enforcement Administration is aware of the bust and federal charges are likely, Lawrence said. He said charges against other individuals connected to the case may also be filed.
Jimmy Carter, an investigator with the 16th Judicial District Drug Task Force, assisted in the raid, Lawrence said.
It was unknown as of press time if Sand and Glisson were in custody.
