Light intensity is the amount of light energy delivered to plants, typically measured in micromoles per square meter per second (µmol/m²/s) or lux. In cannabis cultivation, adequate light intensity drives photosynthesis, influencing plant size, bud density, and cannabinoid production. Too little light can cause stretching and weak growth, while excessive light may lead to bleaching or stress. Adjusting fixture height and wattage helps maintain optimal intensity at each growth stage.
