Plant Metabolism

Plant Metabolism refers to the biochemical processes cannabis plants use to convert nutrients, light, and water into growth structures and secondary compounds like cannabinoids and terpenes. Understanding metabolic pathways—photosynthesis, nutrient uptake, and biosynthesis—is central to cannabis breeding and cultivation genetics. Different cultivars show variation in metabolic efficiency, affecting growth speed, yield potential, and the production of target compounds. Breeders select for traits like nutrient responsiveness, light-use efficiency, and metabolic robustness to optimize performance across growing environments. Metabolism also influences how plants respond to stress, which can trigger shifts in cannabinoid and terpene profiles. Knowledge of metabolic genetics helps explain phenotypic variation and informs decisions about cultivation inputs and timing.

Breeders work with metabolic traits to develop cultivars suited to specific growing systems—fast-finishing varieties for short seasons, nutrient-efficient plants for resource-limited environments, and high-yielding genetics optimized for light conversion. Selecting for metabolic resilience improves consistency across harvest cycles and growing conditions.
