Cannabis achene and embryo microstructure, cotyledons, radicle position, storage organelles, reserve mobilization, and structural changes during germination.
Visual lesson 05
Germination failure patterns
Compare stalled seeds, damping-off risk, shell retention, excessive moisture, and temperature-related delays without assuming one cause from appearance alone.
Interactive academic visual
Germination failure patterns
Compare patterns and conditions without diagnosing from appearance aloneStalled
A hydrated seed can fail to progress for many reasons, including low viability or unsuitable environmental conditions; timing alone does not identify the cause.

PracticeCan you explain what the visual is showing?
Why is a single stalled seed not enough to identify the cause of germination failure?
