Feeding Intensity Scale

The Feeding Intensity Scale is a breeding classification system used to categorize cannabis cultivars by their nutrient uptake demands and fertilizer responsiveness. Strains vary widely in how much nitrogen, phosphorus, potassium, and micronutrients they require during vegetative and flowering stages. Low-intensity feeders thrive on minimal nutrient input, while high-intensity feeders show robust growth and yield potential when provided abundant nutrients. Breeders working in both indoor and outdoor environments often document feeding profiles as part of cultivar characterization. Understanding a strain's position on this scale helps guide cultivation protocols and soil composition decisions. This trait also influences cost-efficiency and scalability in production systems.

Breeders select for feeding intensity to match specific cultivation environments—low-intensity genetics suit organic or amended soil systems, while high-intensity selections drive performance in hydroponic and controlled-feed setups. Feed-responsive phenotypes are often prioritized in commercial breeding programs targeting yield optimization.
