Cannabis worth an estimated £250,000 has been found in Nottingham after police raids on two houses.
Officers found 600 plants at the two houses in Albert Grove on Tuesday following a tip-off that cannabis was being grown at the properties.
The electricity supply to the houses had also been tampered with to provide light for the plants, police said.
Hung Van Tran, 40 and of no fixed abode, was arrested and charged with the production of cannabis.
Mr Van Tran appeared before Nottingham Magistrates on Tuesday and was remanded in custody.
Pc Kirstie Packwood, beat manager for the Lenton triangle, said: "We have been investigating the growing of cannabis in the Lenton area for some time and today's raids at two addresses were the culmination of that investigation.
"It is a large amount of cannabis to find and we are delighted to have discovered the plants before they ended up being sold on the streets of Nottingham.
"We estimate they are worth in the region of £250,000. They will now be destroyed," she said.
