The light deprivation system uses blackout materials to control the exposure to light and darkness, simulating seasonal changes. The automated manipulation of light and darkness prompts plants to flower as instructed, reducing maturation time and enabling year-round cultivation and multiple harvests.Plants that typically thrive in the fall have been shown to respond well to limited light conditions in greenhouses. Licensed cannabis growers have found that a light deprivation greenhouse is the fastest way to achieve multiple harvests. Some of the most famous plants that thrive in reduced light conditions include asters, Christmas cactus, cosmos, mums, poinsettias, and zinnias.
