Yes, light deprivation is highly effective for flowering plants, as it allows growers to control the timing of the flowering process by manipulating light exposure. Many flowering plants are photoperiod-sensitive, meaning they rely on specific day-length cues to begin blooming.
By using light deprivation techniques, growers can simulate shorter days, typically reducing light exposure to around 12 hours or less, which mimics the natural conditions that trigger flowering. This controlled environment enables plants to bloom earlier or out of season, allowing for multiple flowering cycles in a year.
