Photoperiod dependent cannabis varieties are those that require a change in the amount of light they receive to enter their flowering cycle and produce buds.
Cannabis plants typically require a 12h light and 12h darkness period to enter the flowering cycle. If the plant receives more than 12h of light, it remains in the vegetative cycle and does not start producing buds.
These strains are popular among cannabis cultivators due to their ability to produce higher-yielding cultivation than auto-flowering seeds, although the growing cycle is longer. The plants tend to acquire a larger size.
The photoperiod dependent seeds were the only seeds available on the market until the emergence of the auto-flowering seeds. Generally, cultivators choose photoperiod dependent strains because they offer greater control over the growth cycle and a higher potential yield.
There are both feminised and regular photoperiod dependent cannabis seeds.
