Height Expression
Height expression refers to the genetic and environmental factors that determine plant stature in cannabis cultivation. This trait encompasses the plant's vertical growth pattern, internode spacing, and overall structural development from seedling through flowering. Cannabis exhibits wide phenotypic variation in height, ranging from compact, bushy forms to tall, columnar structures—variation largely influenced by both genetic background and growing conditions. Understanding height expression is essential for indoor cultivation planning, outdoor spacing, and breeding programs targeting specific grow environments. Height traits are often polygenic, meaning multiple genes contribute to the final phenotype, and environmental factors like light intensity, photoperiod, and nutrient availability significantly modify genetic potential.

Breeders selectively work with height expression to develop cultivars suited to specific cultivation methods—compact varieties for constrained indoor spaces or tall-frame plants for outdoor production. Mapping height-related traits across lineages helps predictably guide F1 and F2 stability in new crosses.
