Cannabis gas exchange, photosynthesis, transpiration, stomatal conductance, PPFD, temperature, and carbon-dioxide response under measured conditions.
Visual lesson 05
Root-zone interaction
Overlay media moisture, oxygen, pH, EC, root temperature, and atmospheric demand to show why plant response depends on the whole system.
Interactive academic visual
Root-zone interaction
Moisture, oxygen, pH, EC, temperature and atmospheric demand operate as one systemMoisture
Water content controls supply while also affecting gas-filled pore space and root-zone oxygen diffusion.
