Cannabis leaf gas exchange under varying PPFD, temperature, and CO2; supports coupled response teaching while keeping experimental genotype and chamber conditions explicit.
Visual lesson 10
Coupled environmental limits
Explore how light, CO2, temperature, VPD, airflow, and root-zone supply can constrain one another so increasing one resource does not guarantee a proportional response when another process becomes limiting.
