Vertical Growth Regulators
Vertical Growth Regulators (VGRs) refer to genetic traits and plant structures that breeders select for to control height and node spacing in cannabis cultivars. These traits influence internode length—the distance between branching points—and overall plant architecture during vegetative growth. Lineage records frequently report that cultivars from Short Bus, Afgani, and other compact-plant lineages carry strong vertical regulation genetics. Selection for VGRs is particularly relevant in controlled-environment breeding, where space constraints and canopy uniformity are production priorities. Understanding these structural traits helps breeders predict plant form across generations and optimize cultivation protocols.

Breeders working with VGRs strategically cross compact or bushy phenotypes with taller cultivars to achieve desired plant heights and branching patterns for specific grow environments. VGR selection is foundational in stabilizing F1 hybrids and creating photoperiod-dependent lines suited to indoor or outdoor production systems.
