The frequency of adjusting light cycles in a light deprivation greenhouse depends on the specific growth stage of the crop and its photoperiod requirements. For photoperiod-sensitive plants, the light cycle is typically adjusted as they transition from vegetative growth to flowering or fruiting.
Early in the growing cycle, many crops thrive with longer daylight hours, simulating summer conditions to promote vegetative growth. As the plants reach the stage where flowering or fruit production is desired, the light cycle is reduced to shorter day lengths, mimicking the transition to fall.
