light deprivation greenhouse Light deprivation is a useful growing technique often implemented to encourage or discourage flowering in plants outside their regular seasonal schedule. Using blackout tarps to simulate the seasons' changing, growers can take advantage of up to three harvests: early summer, late summer, and winter.

Growers accomplish this by controlling how much and how often plants receive light. Plants sense the amount of day and night hours using their circadian clock to determine whether they should be working on growing foliage, producing seed, or heading into dormancy.

Plants collect information from their environment, actually right from their leaves. They are sensitive to light, temperature, and length of daylight (the photoperiod). Plants are categorized by how they react to changes in the photoperiod. These plant reactions to the photoperiod are Short-Day plants, Long-Day plants, and Day-Neutral.

HOW DO LIGHT DEPRIVATION TECHNIQUES FORCE FLOWERING ON SHORT-DAY PLANTS?

Rather than producing more foliage and branches, asexual reproduction, plants rush to make flowers, a form of sexual reproduction, because their circadian clock believes it is later in the season. The reduced day length from the typical 18 hour day length of the spring signals to the plant that it is time to spread seed for survival. Plants also begin to release all of those starches they use when growing for foliage, along with hormones that signal the plant to start to form flowers and fruit as a form of self-preservation. Energy and sugars are put into the fruit and flowers to attract pollinators to fertilize and for animals to help spread the seed.
