What Are Autoflower Seeds?

Autoflower seeds are a type of cannabis genetics that automatically transition from the vegetative stage to the flowering stage without the need for a change in light cycles.

Among marijuana growers, they’re considered more simple to grow and harvest than feminized marijuana seeds, as they have been bred to flower based on their age and do not demand light cycle changes. 

This makes them ideal for growers who want a quick turnaround and multiple harvests in a year.

What Makes Autoflower Seeds Unique?

Here, we discuss a few factors that make autoflower seeds unique.

Faster Harvests

Autoflowering plants typically go from seed to harvest in just 8 to 10 weeks, unlike photoperiod strains that can take up to 16 weeks to fully flower.

Because of its quick development, gardeners can harvest numerous times a year and can try out new strains and growing methods.

Smaller Size and Discrete Growth

Autoflower marijuana seeds tend to stay small and bushy, making them ideal for indoor cultivation or areas with limited space. The plants are easy to transport and care for.

Their discrete nature also makes them suitable for stealthy outdoor grows as well, as they can easily blend in with other plants or landscapes.

Suitable for Various Environments

Autoflower seeds have been specially bred to thrive in various environments, making them versatile and adaptable. 

Autoflowering strains are resistant to a wide range of environmental factors, regardless of whether they are grown outdoors, in a greenhouse, or under regulated indoor circumstances. 

So, no matter if you’re from the east coast, west coast, the south or the north, autoflower seeds can thrive in various environments.

The Process of Growing Autoflower Seeds

Many Cannabis seed banks provide you with a guide on how to germinate marijuana seeds properly and we advise following it.

Early Growth Stage

Autoflower plants focus on developing a strong root system and building a sturdy stem when they’re in early stages of growing. 

Ensure that they’re getting enough light, nutrients, and are being watered properly to allow a significant boost in their growth.

Vegetative Phase

Unlike photoperiod strains, autoflower seeds do not have a distinct vegetative phase. Instead, they transition directly from the early growth stage to flowering.

Flowering Stage

The flowering stage, which lasts for 6 to 8 weeks, is when autoflower plants start to produce buds.

During this period, make sure to monitor the plants closely and adjust the nutrient levels accordingly. 


Once the buds have reached their peak maturity, it’s time to harvest your autoflower plants. Look into the growing guides provided by your preferred seed bank and follow the instructions regarding harvesting and drying.
