Vigor Vigor Class

Vigor class refers to a plant's growth rate, resilience, and biomass production characteristics—traits breeders assess during development cycles. Strong vigor is commonly associated with faster vegetative growth, robust root development, and efficient nutrient uptake. This classification helps breeders identify genetics suitable for cultivation in varied environments and stress conditions. Vigor is often scored on relative scales across phenotypes within a strain family, rather than as a terpene per se, but is frequently tracked alongside chemical profiles. Understanding vigor markers supports breeding decisions for both commercial and preservation programs.

Breeders prioritize vigor assessment when selecting parent plants, as high-vigor traits can improve yield potential, disease resistance, and adaptability to different growing systems. Vigor data collected across multiple generations helps establish stable cultivars with predictable growth characteristics.
