Greenhouse Management Online

Greenhouse Management Online Training

— Offered by Dale Bumpers College of Agricultural, Food, and Life Sciences and the Department of Horticulture —

Grow your career with our online, non-credit course for industry professionals.

Growing plants in controlled environments such as greenhouses and indoor vertical farming operations is becoming increasingly important for production of high-value food, pharmaceutical, and ornamental crops. This course begins with an overview of the controlled environment (CE) industry and a review of the principles of horticulture. You will then learn key fundamentals of greenhouse and CE management, including fertilizer nutrients and irrigation, soilless growing substrates, water quality, plant height control, supplemental and photoperiodic lighting, pests, and crop scheduling. Participants will also learn about cutting-edge CE technologies for greenhouse structures and design, heating and cooling systems, fertilization/irrigation equipment, electric lighting, environmental control computers, hydroponics, robotics and automation.
