As a yield-boosting method, training plants allows cannabis growers to make the most of their available space and light. This training technique involves gently bending and tying down cannabis plant branches and stems. Cannabis normally grows one large main stem that develops one large, elongated cola. This exists alongside other, smaller side-branches with smaller buds. With plant training, the goal is to break this apical dominance, instead flattening out the canopy to grow at the same height.
