Low-stress training is the highest-return technique in growing: zero cost, no recovery time, and yield gains of 40 %+ over an untrained plant under the same light. You're not cutting anything — you're bending the plant flat so every bud site becomes a top.
Why it works: apical dominance
Cannabis pours energy into whatever tip sits highest, hormonally suppressing everything below it. Bend that main tip horizontal and the suppression signal collapses — every side branch responds as if it were the main cola. One plant becomes a dozen tops of equal rank.
