THC Academy course
Branching, Training & Canopy Architecture
Connect node anatomy and apical dominance to topping, low-stress training, mainlining, and screen-based canopy organization.
Course outcomes
What you should be able to do
- Locate nodes, internodes, axillary buds, and active shoot tips.
- Explain apical dominance and why branch responses differ after training.
- Compare topping, directional training, mainlining, and screen-based canopy organization.
- Evaluate training by canopy structure, light distribution, recovery, and plant condition instead of unsupported yield claims.
