A potometer estimates water uptake, which is commonly used as an indirect measure of transpiration.
Scientific interpretation will appear after the trial.
Scientific note: Adjust environmental conditions and run the potometer model. Compare bubble movement over time.
Model ready. Choose a condition and run the model to see an observation.
