Give seedlings a quality, well-draining medium such as coco coir, peat, or a blend with perlite. Keep conditions steady, provide suitable nutrients as plants develop, and avoid overwatering. Indoors, an 18/6 or 20/4 light schedule supports vigorous growth.
Plants can reach about 1.5 m and develop a strong central stem with sturdy side branches. Choose a sunny outdoor site or a well-equipped indoor space with good airflow. Keep daytime temperatures around 68–80°F and adjust humidity downward as flowering progresses.
