Student Learning Outcomes -
  • Demonstrate skill required to maintain greenhouse and nursery facilities
  • Identify major types of growing structures and their respective roles in commercial plant production.
Description -
Commercial greenhouse management as related to the production of plants in California. Emphasis is on greenhouse operations. Class will focus on organization, management, and production practices used in large and small-scale commercial greenhouse plant production. Greenhouse operations and the utilization of technology will be emphasized through use of on-campus facilities and observation of off-site operations.

Course Objectives -
The student will be able to:
  1. organize, schedule, and implement skills and practices used in the production and merchandising of a greenhouse crop.
  2. demonstrate skills required to maintain greenhouse facilities.
  3. identify major types of growing structures and their respective roles in commercial plant production.
  4. determine the types of materials and environmental control systems required for the production of major greenhouse crops.
  5. demonstrate, through written examinations, the various aspects of greenhouse design, construction, and operation utilized in the green industry.
  6. demonstrate, through written examinations, the development and care of horticultural crops in a greenhouse environment.
  7. recognize the use of greenhouse operations in different cultures.
Special Facilities and/or Equipment -
Horticultural laboratory, greenhouse, lath house and related horticultural facilities and equipment. Students provide pruning shears with sheath, work boots, leather gloves and clothing for fieldwork.
