Photoperiod

Photoperiod cannabis seeds produce plants that rely on changes in the light cycle to move from vegetative growth into flowering. Outdoors, this usually happens naturally as the days shorten towards the end of summer. Indoors, growers can control the switch by adjusting the light schedule. This gives cultivators more control over plant size, training time, and when flowering begins.

At Seedsman, the Photoperiod category features a wide range of cannabis genetics from established breeders, including feminised and regular seed options. Photoperiod strains are popular with growers who want greater flexibility, larger plant potential, and more time to shape plants before bloom. They are especially valued for training techniques, mother plant selection, cloning, full-season outdoor growing, and high-yield potential.
