Manipulate light to affect plant growth.

Definition

Manipulation should include
  • measuring light
  • differentiating among color, intensity, and duration
  • interpreting daily light integral (DLI) measurements
  • defining light saturation and light compensation
  • acclimatizing plants
  • describing how photoperiodism affects growth
  • exploring the use of time clock devices set for night-interruption and day-extension lighting
  • exploring the use of black cloth for night extension.

Process/Skill Questions

  • How can a grower regulate light intensity and duration?
  • What types of plants must be acclimatized?
  • How is the use of LED light changing plant growth?
