Cannabis responses to contrasting daily light integrals and short-term PPFD, including photosynthetic acclimation and water-use responses; supports separating DLI from instantaneous PPFD.
Visual lesson 09
Light acclimation & canopy position
Compare leaves developed under different local photon environments to show how photosynthetic traits can acclimate across canopy positions, while avoiding the assumption that one leaf response directly predicts whole-plant yield or flower quality.
