We designed an interdisciplinary project-based learning course in hydroponics for undergraduate non-science major students. Students worked in teams to design, build, and maintain plants in various types of hydroponic systems over the semester. In three semesters of teaching the course, students consistently demonstrated knowledge of course material and became confident in growing plants by hydroponic methods. Students reported the project-based, team-based, and mini-lecture aspects of the course increased their learning and motivation in the course.
