Growth Stretch Ratio
Growth Stretch Ratio refers to the relationship between vegetative expansion and flowering-phase vertical extension in cannabis cultivars. Plants exhibiting low stretch ratios remain relatively compact during flower, while high-stretch varieties can double or triple in height once flowering begins. Breeders track this trait because it directly impacts canopy management, yield structure, and cultivation space requirements. Lineage records frequently report stretch behavior as a heritable characteristic—offspring often mirror parental phenotypes in this regard. Understanding a strain family's typical stretch ratio is essential for selecting genetics suited to specific grow environments, whether constrained indoor rooms or open outdoor plots.

Breeders working in confined spaces prioritize low-stretch cultivars to maximize canopy density and reduce vertical demand. Conversely, breeders developing outdoor or high-ceiling genetics may select for moderate stretch to increase internode spacing and air circulation, reducing pest and mold pressure.
