THC Academy course
Seed, Germination & Establishment
Follow the seed from anatomy and water uptake through radicle emergence, cotyledon transition, and common establishment failures.
Course outcomes
What you should be able to do
- Identify major seed structures and connect them to germination.
- Distinguish imbibition, radicle emergence, cotyledon opening, and first true-leaf development.
- Separate seed viability questions from environmental establishment failures.
- Record germination as a repeatable batch process rather than a memory-based result.
