Cultivation Technique Low Stress Training

Low Stress Training (LST) refers to a set of cultivation techniques that gently manipulate plant structure without causing significant plant damage. Common methods include bending stems, tying branches, and adjusting canopy position to expose lower growth nodes to light. These techniques are distinct from high-stress methods and are often employed by breeders and cultivators working to maximize canopy uniformity and light penetration. LST is frequently applied to both photoperiod and autoflowering varieties, though timing and application vary by genetics and cultivation environment. Lineage records and breeding notes often reference LST-responsiveness as a desirable trait in cultivar development, particularly for indoor and controlled-environment production.

Breeders select for LST-friendly morphology—including flexible stems, lateral branch vigor, and responsive growth patterns—when developing cultivars suited to high-density or controlled canopy systems. Genetics with naturally bushy structure and strong apical dominance recovery are commonly prioritized in breeding programs targeting growers who employ these techniques.
