Autoflowering vs photoperiod cannabis seeds

Autoflowering vs. photoperiodische Cannabissamen

As you move into the world of cannabis cultivation, you will discover two primary types of seeds: autoflowering and photoperiod (Full Season & Fast Flowering seeds). Choosing between these seeds can have a significant impact on your growing cycle, your harvest, and your overall growing experience. In this article, we'll explore the differences between autoflowering and traditional photoperiod seeds and help you make the best choice for your growing conditions.

Autoflowering seeds: speed and simplicity

Autoflowering cannabis seeds are known for their ability to flower regardless of lighting conditions. They come from Cannabis Ruderalis, a species that can adapt to extreme climates and lack of light. Here are the main features of autoflowering seeds:

1. Independent Flowering : They flower automatically after a set time, mostly after 2-4 weeks of growth, without the need for any change in light cycle.

2. Fast Harvest : Autoflowering plants are typically ready from seed to harvest in 8-10 weeks.

3. Compact size : Ideal for small growing spaces as they rarely reach heights over 1-1.5 meters.

4. Hardiness : They are often more resilient to environmental stresses, pests and diseases.

Photoperiod seeds: flexibility and potential

Photoperiod cannabis seeds, on the other hand, are the traditional seeds that flower depending on the lighting conditions. They require specific light cycles – typically 12 hours of light and 12 hours of darkness – to enter the flowering phase. Their main advantages are:

1. Higher Yields : With proper care and under optimal conditions, they tend to produce larger harvests than autoflowering plants.

2. Adjustable growing season : The growing season can be extended to increase plant size and therefore yield.

3. Diverse Strain Selection : There is a wider selection of photoperiod seeds, allowing for more variety in flavor, potency and effects.

Main differences at a glance

1. Light Requirements: Autoflowering seeds do not require changes in the light cycle to flower, while photoperiod seeds require a fixed light schedule.

2. Growing and flowering time : Autoflowering seeds result in plants that flower and are ready to harvest more quickly, while photoperiod seeds have a longer growing and flowering time.

3. Size and Yield : Autoflowering plants stay smaller, which can result in lower yields. Photoperiod plants can grow larger and more productive with appropriate care.

4. Growing Environment : Autoflowering plants do well in smaller, more controlled environments, while photoperiod plants require more space and more precise light control.


Choosing between autoflowering and photoperiod seeds depends on your personal preferences, your growing environment, and your goals as a grower. Autoflowering seeds offer a quick and easy way to grow cannabis, while photoperiod seeds offer a longer growing season and potentially higher yields. No matter which seeds you choose, an informed decision will surely lead to success in your cultivation.
