Thrips are small, slender insects that can pose a threat to cannabis plants by feeding on their leaves and stems. They are often identified by the silvery or bronze-colored patches they leave behind, making their presence noticeable in infested gardens or on plants. Thrips can be found in cultivation areas, often on the underside of leaves where they suck out plant juices, leaving visible damage.
