Using Biological Clocks to Improve Indoor Plant Growing Systems

AI simplified

Abstract

Controlled environment agriculture (CEA) allows horticultural production all year round by precisely controlling environmental inputs.

  • Light and temperature are essential in regulating the circadian clock, aligning plant processes with day-night cycles.
  • Dynamic adjustments of light intensity and temperature may enhance plant growth and metabolism in CEA systems.
  • Shifting from natural to controlled environmental regimes can extend beyond typical day-night cycles.
  • Integrating chronobiology with horticultural practices could optimize crop performance in CEA.
  • Research priorities are needed to improve diurnal environmental management strategies in CEA.
