Photoperiod

What Are Photoperiod Seeds?

Photoperiod seeds are a foundational category in cannabis cultivation, preferred by growers seeking control over flowering time, strain genetics, and yield outcomes. Photoperiod strains require a manual light cycle shift to transition from the vegetative to the flowering stage.

Photoperiod vs Autoflower Seeds

When it comes to photoperiod vs. autoflower, the big difference is how they handle light. Photoperiod seeds require you to switch the light cycle, like from 18 hours of light down to 12, to kick off flowering. Autoflowers don’t care about the light schedule — they just do their thing on their own. Some growers like photoperiod strains because they get more control over how big the plant gets and when it flowers. But if you’re looking for something low-maintenance and fast, autoflowers are way easier to manage.

When Do Photoperiod Plants Typically Flower?

Photoperiod seed to harvest time is a bit tricky to estimate exactly, but photoperiod plants usually start flowering when they get about 12 hours of darkness each night. Most growers make the switch from the veg stage to the flowering stage by adjusting their light cycle to 12 hours on and 12 hours off. Once that happens, you’ll start to see signs of flowering within a week or two. Indica strains tend to flower faster, sometimes finishing in around 8 weeks, while sativas can take 10 to 12 weeks or even longer. It all depends on the genetics, but the light schedule is what really kicks things off.
