More than 200 cannabis plants have been found at a city centre home.
Officers raided an address in Ruttington Lane, Canterbury, and discovered the huge cultivation operation.
Two rooms were being used to dry a large quantity of cannabis bud, with a further 224 plants in the early stages of growth.
They were removed from the property following the raid last Monday.
No arrests have been made and officers are keen to hear from anyone who has witnessed suspicious activity in the area.
