Growth Stage Profiles

Growth stage profiles describe how terpene composition shifts across cannabis plant development—from seedling through vegetative, flowering, and maturation phases. Different terpenes accumulate at different rates; some early-stage dominants (like pinene) may decline as late-stage terpenes (like myrcene and caryophyllene) increase. Understanding these temporal patterns helps breeders predict final chemotypes and optimize harvest timing for desired aromatic outcomes. Lineage records frequently show that terpene ratios stabilize only in late flowering, making mid-flower sampling unreliable for strain identification. Environmental factors—light, temperature, nutrients—significantly influence the speed and magnitude of these shifts across all strains.

Breeders use growth stage profiling to identify stable vs. unstable lineages and to select parents whose terpene trajectories produce consistent final profiles across generations. Tracking terpene shifts also informs cultivation decisions and helps distinguish phenotypes within heterozygous crosses.
