High Stress Training
High Stress Training (HST) refers to cultivation techniques that intentionally subject cannabis plants to physical stress—such as bending, breaking, or removing branches—to manipulate growth patterns. Unlike Low Stress Training (LST), which uses gentle, non-damaging methods, HST creates small wounds or breaks that trigger compensatory growth responses. Common HST methods include topping, fimming, and super cropping. Breeders and cultivators employ these techniques to increase canopy spread, improve light penetration, and potentially increase yield in controlled environments. HST requires careful timing and plant health assessment, as improper execution or application during vulnerable growth stages can reduce vigor or introduce stress-related vulnerabilities.

Breeders evaluating strain resilience often use HST protocols to assess plant recovery capacity and structural integrity under stress. Genetic lines showing robust regrowth and rapid wound closure are frequently selected for breeding programs targeting durability and production efficiency in intensive cultivation systems.
