Light deprivation techniques affect plant growth by manipulating the light cycle to simulate shorter days, which influences a plant's natural response to changes in daylight. By controlling the amount of light plants receive, growers can induce flowering or fruiting earlier than in natural conditions, regardless of the season.
This is particularly useful for plants that are photoperiod-sensitive, meaning they respond to specific lengths of light and dark periods to trigger growth phases like flowering. Light deprivation can accelerate a plant’s life cycle, allowing multiple harvests in a year.
