Feeding Demand Genetics

Feeding Demand Genetics refers to the inherited traits that determine how intensively a cannabis plant utilizes nitrogen, phosphorus, potassium, and micronutrients during growth and flowering. These characteristics vary across cultivars and lineages, influencing nutrient uptake rates, deficiency tolerance, and responsiveness to fertilizer regimens. Breeders document feeding demand as a key cultivation variable, with some lines showing "heavy feeder" profiles while others demonstrate efficient nutrient conversion on minimal inputs. Understanding feeding demand helps growers match cultivar selection to their growing medium, water quality, and nutrient availability. This trait is particularly relevant in soil-based, hydroponic, and organic cultivation contexts where nutrient schedules must align with plant genetics.

Breeders select for feeding demand traits to create cultivars suited to specific agricultural systems and grower skill levels. Lines developed for commercial hydroponics often carry heavy-feeding genetics, while cultivars bred for outdoor or low-input environments typically show more nutrient-efficient phenotypes.
