Course: Greenhouse Plant Production and Management (18052-III) > Section: Operating Plant Production Facilities

Comparison should include

- factors that influence lighting selection
- photoperiodism needs
- types of systems
  - incandescent
  - light-emitting diode (LED)
  - high-intensity discharge (HID) (e.g., metal halide, high-pressure sodium)

Process/Skill Questions:

- How does light affect photoperiodism?
- How can flowering be manipulated by lighting?
- How does light color, intensity, and duration affect plant growth?
- When is one type of lighting system preferable over another?
