Cannabis gas exchange, photosynthesis, transpiration, stomatal conductance, PPFD, temperature, and carbon-dioxide response under measured conditions.
Visual lesson 01
Light distribution
Map high- and low-light zones across the canopy and connect PPFD distribution to leaf position and canopy architecture.
Interactive academic visual
Canopy light distribution
Map PPFD spatially instead of relying on one center readingLight source
Fixture geometry, optics, mounting height and dimming determine the incident light field before the canopy modifies it.
Knowledge check
PracticeCan you explain what the visual is showing?
Why can PPFD differ within the same canopy?
