Gardai in Leitrim discovered what has been described as a 'sophisticated' cannabis grow house over the weekend.
Officers from the regional drugs unit searched a home and discovered a number of plants.
No arrests have been made and investigations are ongoing.
The most senior Garda in the north-west has admitted there is a worrying trend of drug grow houses being discovered in County Leitrim.
Chief Superintendent Aidan Glacken also revealed there is a worrying rise in the number of people being detected driving while under the influence of cannabis or cocaine.
The Final Joint Policing Committee meeting of the year in Leitrim heard while drink driving incidents had decreased in the last 12 months, people in charge of vehicles driving under the influence of illegal drugs was increasing.
Chief Superintendent Aidan Glacken claimed that the detection of cannabis and cocaine in drivers was becoming more common, with 18 people arrested for drug driving this year in Leitrim - and some of whom were operating HGVs at the time of their arrest.
The Garda chief also suggested that a number of people 'outside of the jurisdiction' were involved in the operation of grow houses in the county.
Six have now been detected so far this year - while a total of eight were reported between 2017, 2018 and 2019 combined.
He claimed that houses in isolated areas are often used by criminals and that they use vulnerable people to be gardeners for the drugs
Over 3300 garda patrols have taken place this year and over 1600 checkpoints which is a large increase on previous years' figures - which the Garda chief suggested was linked to Covid enforcement.]
