Cannabis gas exchange, photosynthesis, transpiration, stomatal conductance, PPFD, temperature, and carbon-dioxide response under measured conditions.
Visual lesson 04
Airflow & boundary layer
Visualize air movement around leaves and the still-air boundary layer that influences heat and vapor exchange.
Interactive academic visual
Airflow & boundary layer
Air movement changes the still-air layer around leaves and therefore heat and vapor exchangeLeaf surface
A leaf exchanges heat, water vapor and gases with the surrounding air across its surface and stomatal pores.
Knowledge check
PracticeCan you explain what the visual is showing?
How does stronger air movement around a leaf generally affect the still-air boundary layer?
