Training Techniques

Training Techniques refers to horticultural methods breeders and cultivators apply to cannabis plants during vegetative growth to influence plant architecture, canopy structure, and ultimately cannabinoid/terpene expression. Common approaches include topping, low-stress training (LST), and defoliation—each affecting how a plant allocates resources and develops lateral branching. These methods do not alter terpene profiles directly but can influence secondary metabolite concentration by modifying light exposure, nutrient distribution, and stress responses during development. Breeders studying terpene stability across phenotypes often employ consistent training protocols to isolate genetic vs. environmental factors. Understanding training's role in cultivation consistency is essential for producing reproducible batches within a strain family.

Breeders use standardized training protocols during phenotype evaluation to ensure fair comparison of genetic traits and terpene expression between candidate plants. Consistent training also helps identify which genetic lines produce desired terpene profiles under realistic cultivation conditions.
