Police in Rotherham uncovered two sophisticated cannabis farms hidden behind fake walls and a disguised loft hatch during simultaneous raids on Goosebutt Court, Parkgate.
Officers seized 170 plants worth an estimated £170,000, along with 600 seedlings.
Hidden compartments, including a concealed basement entrance and a loft hatch covered by a false ceiling, were used to disguise the operation.
Three men, aged 51, 30, and 23, were arrested on suspicion of cannabis production.
