Lst Low Stress Training

Low Stress Training (LST) is a cultivation technique where growers gently bend and secure plant stems to create a more horizontal canopy structure rather than the natural vertical growth pattern. This method differs from high-stress techniques like topping or pruning, as it avoids removing plant material and relies instead on mechanical manipulation using ties, clips, or weights. LST is commonly applied during vegetative growth to redistribute auxin hormones and encourage lateral branching. The approach aims to create an even canopy with multiple main colas rather than a single apical (top) flower site. Breeders and cultivators often categorize strains by their structural response to LST—some genetics naturally accommodate horizontal training more readily than others depending on stem flexibility and branching architecture.

Breeders working in commercial and home cultivation settings select for plant structures with flexible stems and responsive branching patterns that work well under LST protocols. Lineage records frequently report how certain cultivars display superior lateral growth and structural compliance when trained horizontally, making these genetics valuable for optimization-focused breeding programs.
