Cannabis/hemp seed germination percentage and rate across constant temperatures, including cultivar-specific cardinal temperature estimates and priming effects. Use study-specific values as examples, not universal species thresholds.
Visual lesson 07
Thermal limits & germination rate
Separate final germination percentage from the speed of germination, then use hemp seed studies to show how temperature can alter both while keeping published cardinal-temperature estimates specific to the tested cultivar, seed lot, and method.

PracticeCan you explain what the visual is showing?
Why should a Cannabis seed temperature study separate final germination percentage from germination rate?
