Training & Plant Architecture
Testing Training Methods with Controlled Comparisons
Training claims are best tested with comparable plants, a defined untreated or standard-practice control, replication, consistent environment, and measurements selected before the trial begins.
Key concepts
- One impressive plant does not establish a treatment effect
- Training method and vegetative duration can be confounded
- Plant density and cultivar can change the response
- A useful trial defines the outcome before seeing the result
What to measure or observe
- Choose one training variable to compare
- Use comparable starting plants
- Replicate each treatment
- Measure canopy area, light distribution, labor, recovery, yield, and quality consistently
Common mistakes
- Giving the trained plant more vegetative time than the control
- Comparing different cultivars
- Selecting the best plant from one group and average plant from another
- Ignoring added labor and recovery time
