Officers carried out a warrant at the house, on Albany Road, at around 2.30pm on Tuesday, February 8.
Once inside the property, detectives found the cannabis farm stretched over five rooms and 196 plants were seized.

A 33-year-old man was arrested at the property on suspicion of cannabis cultivation and abstracting electricity and questioned by police in custody.
Detectives recovered all of the plants in the property and made the house safe.

Community Policing Sergeant Anna Matthews said: "Thanks to our officers, a large cannabis farm is no longer putting our community at risk of fire and flood, as well as violence and criminal exploitation.
“No law abiding person wants to live next-door to such death-traps and we do all we can to make the streets safer.
"Keep your eyes, ears and noses open to the signs that cannabis is being grown where you live and work and we will keep taking action. All information helps the work we do, so make us aware and we'll be there."
In a later statement, a spokeswoman for the force added: "We have now charged 33-year-old Lumir Muja, of no fixed address with cannabis production in relation to the below.
"He has been remanded in custody and appeared in court this morning, Wednesday 9 February."
