Which of the following pests is commonly known to affect cannabis plants?

Spider mites are commonly known to affect cannabis plants due to their ability to thrive in the relatively warm and dry environments that are often found in indoor cultivation settings. These pests feed on the plant's sap, which can lead to significant damage, manifested through discoloration and stippling of leaves, ultimately weakening the plant and reducing its overall yield.

Spider mites reproduce rapidly, and populations can explode quickly if not managed effectively. Their presence can be identified by examining foliage for fine webs and small specks, which are indicative of their feeding activity. Additionally, their ability to adapt to various environmental conditions makes them a persistent threat in cannabis cultivation.

While other pests like whiteflies, fungus gnats, and mealybugs can also affect cannabis plants, spider mites are notably one of the most challenging and impactful pests in this specific context. This is why the identification of spider mites as a significant pest in cannabis cultivation is essential for growers looking to maintain healthy plants and optimize their yields.
