Master grower

Master grower is the senior cultivation role at a commercial cannabis facility — often also titled Director of Cultivation or Cultivation Manager — with end-to-end responsibility for the cultivation program: strain and genetics library management, integrated pest management, nutrient and irrigation regimens, environmental controls (HVAC, lighting, CO₂, VPD), crop scheduling, SOPs, track-and-trace compliance, team management, yield forecasting, and increasingly P&L accountability. Industry guidance (Ryan Douglas, former Tweed master grower) recommends hiring commercial horticulture veterans rather than cannabis-only hobbyists, since most concepts transfer from ornamental or edible crop production. Salary ranges span $120,000–$150,000 typically, with top-tier commercial growers earning $250,000–$300,000; Glassdoor reports a median near $155,000. A March 2026 MJBizDaily feature described master growers as "the hardest job in cannabis, and the most lucrative" amid price compression, with operators competing for a small pool of leaders who balance biology, compliance, and financial performance. Many require a bachelor's in horticulture, plant science, or agronomy, plus state key-employee licensing. → See also: Head grower, Cultivator, Compliance
