During the execution of the search warrant, agents discovered elaborate hidden compartments in the house as well as a room that was concealed by a false wall, police said. The concealment of the compartments was complicated and required a combination of several steps to access, according to authorities.
Bartow-Cartersville Drug Task Force Commander Capt. Mark Mayton said agents were still assessing the value of the growing operation on Monday but he believed it to be at least $350,000 and was capable of producing millions of dollars worth of high-grade marijuana.
Police said the amount of growing equipment seized was "overwhelming" and had to be removed with a tractor-trailer.
Officials also seized a trafficking amount of methamphetamine, several vehicles, weapons and a "large amount" of cash, Mayton said.
Ricky Paul Holt, 53, Elaine Black Holt, 49, Kayla Renee Black, 19, and Christopher Dale Black, 22, were all arrested and charged. They are in jail pending a bond hearing.
Police said they do expect more arrests in the case.
