Gardaí in Monaghan have discovered a cannabis grow house in the Ballybay area this morning.
Around 100 cannabis plants were found in a wooded area in Larragh.
It is believed the drugs are worth around €50,000.
The scene is currently preserved for a technical exam.
No one has been arrested in connection with the find.
It follows the discovery of a "substantial" grow house in Co Waterford yesterday during which more than 1,000 cannabis plants at various stages of growth with an estimated value of €800,000 were seized.
