Photoperiod cannabis refers to plants that begin flowering based on changes in light exposure rather than age.
WHAT ARE PHOTOPERIOD CANNABIS PLANTS?
Photoperiod plants rely on a specific light cycle to trigger flowering, typically when light exposure is reduced to around 12 hours on and 12 hours off. As long as they receive longer periods of light, they remain in the vegetative stage.
This is the traditional form of cannabis cultivation.
HOW IT’S USED
Photoperiod cannabis is commonly grown:
- Indoors with controlled light schedules
- Outdoors as daylight hours shorten naturally
- By growers who want control over plant size and timing
Growers can extend or shorten the vegetative stage by adjusting light cycles.
WHY IT MATTERS
Photoperiod plants:
- Allow more control over plant structure
- Can recover from stress more easily than autoflowers
- Are well-suited for training and cloning
- Often produce larger plants and yields
They offer flexibility but require stricter light control.
LIMITATIONS & NOTES
Photoperiod plants require consistent darkness during flowering. Light leaks or interruptions can cause stress, delayed flowering, or hermaphroditism. They also generally take longer to finish than autoflowers.
