Vigor Index

Vigor Index is not a terpene but rather a breeding metric used to assess plant robustness, growth rate, and resilience during cultivation cycles. Breeders monitor vigor through observable traits like stem diameter, internode spacing, and recovery speed after stress. High vigor lines often correlate with desirable agronomic traits, though vigor alone does not predict cannabinoid or terpene profile quality. This metric is commonly tracked across seed generations to maintain consistent performance in breeding programs.

Breeders select for vigor to reduce crop loss, improve yield stability, and ensure reliable performance across varying environmental conditions. Vigor assessment helps identify parent plants worth preserving in active breeding libraries.
