Cultivar Size Class
Cultivar Size Class is a categorical system breeders use to describe the expected mature height and lateral spread of cannabis plants under standard growing conditions. Classifications typically range from compact/dwarf varieties (under 3 feet) to tall/vigorous plants (6+ feet), with medium categories in between. This trait is influenced by genetics, photoperiod sensitivity, and internode spacing patterns inherited from parent lines. Size class documentation helps growers select appropriate genetics for space constraints, training methods, and cultivation environments. Historical breeding records frequently note size class as a primary selection criterion alongside yield architecture and flowering time.

Breeders working in constrained environments (small indoor gardens, limited vertical space) often prioritize dwarf and compact cultivars, while outdoor and greenhouse programs may maintain tall or vigorous lines for canopy density and yield potential. Understanding size class inheritance patterns across hybrid generations helps predict offspring morphology.
