A man was found to be maintaining a cannabis farm with a crop worth more than £180,000 at a disused shop in a Monmouthshire town centre.
Artan Dedia, 36, pleaded guilty to the production of cannabis when he appeared at Merthyr Crown Court on Wednesday 22 January.
Gwent Police officers seized 652 cannabis plants, worth at least £182,560, after raiding the building on High Street, Chepstow, in November last year.
During the warrant, officers discovered the large-scale cannabis factory was spread across eight rooms and five floors, including the attic, and dismantled hydroponic equipment used to grow the class B drug.
Dedia, 36, was sentenced to 12 months imprisonment.
