Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil is dry. Avoid overwatering, which can lead to root rot. Ensure good drainage.
Reduce watering frequency during the dormant period for indoor plants, allowing the soil to dry out more between waterings.
Prune to shape the plant, remove lower branches to improve airflow, and encourage bushier growth by 'topping' young plants.
Pinching off the top growth stimulates the development of multiple main stems, increasing potential yields. Remove dead or diseased foliage promptly.
Typically propagated from cuttings taken from healthy, vigorous mother plants. Cuttings should be 10-15 cm long, with lower leaves removed, and placed in a rooting medium. Rooting hormones can aid in faster development.
Maintain high humidity and indirect light for cuttings.
Repot young plants as they outgrow their containers, usually every 2-4 weeks during the vegetative stage. Choose pots that are progressively larger. Ensure the new pot has adequate drainage holes.
Repotting is less common for mature flowering plants.

11 known issues from plant disease data
Gray mold on Hemp causes buds and leaves to develop soft brown rot with fuzzy growth, leading to collapse and poor flower quality.
Powdery mildew on Hemp covers leaves with a white dusty coating, causing yellowing, curling, and reduced plant growth and vigor.
Fusarium wilt on Hemp causes lower leaves to yellow and wilt as stems lose water flow, leading to stunting, collapse, and plant death.
Pythium root rot on Hemp causes roots to turn brown and mushy, leaving plants wilted, stunted, and weak even in moist growing media.
Damping-off on Hemp kills seedlings by causing thin water-soaked stems at the base, so young plants topple, shrivel, and die quickly.
Septoria leaf spot on Hemp causes many small brown leaf spots with yellowing, leading to early leaf drop and weakened plant growth.
