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.
Primary visual specification
Interactive coupled-environment limitation network
Create an academically accurate interactive coupled-environment limitation network for the Coupled environmental limits lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.
