Pros & Cons Of Autoflowering Seeds

Autoflowering seeds have gained a lot of popularity in recent years. These types of seeds are known for their ability to flower automatically, regardless of the photoperiod. This means that you can grow them indoors or outdoors, and they will flower without any effort on your part. However, as with anything in life, there are both pros and cons to using auto-flowering seeds. In this article, we will explore these pros and cons in more detail to help you decide if they are right for your needs. 

What are Auto Flowering Seeds? 

Before we dive into the pros and cons of autoflowering seeds, let’s first discuss what they are. As mentioned earlier, auto-flowering seeds are a type of cannabis seed that flowers automatically. This means that they do not require a change in the light cycle to trigger flowering. Traditional photoperiod cannabis plants require a change in the light cycle to switch from vegetative growth to the flowering stage. 

Autoflowering seeds were first created by crossing traditional photoperiod cannabis plants with a wild strain of cannabis known as Cannabis ruderalis. Cannabis ruderalis is a strain of cannabis that grows in the wild and is known for its ability to flower automatically. By crossing traditional photoperiod cannabis plants with Cannabis ruderalis, breeders were able to create a new type of cannabis seed that flowers automatically. 

Pros of Auto Flowering Seeds 

Quick Harvest Time 

One of the biggest advantages of auto-flowering seeds is their quick harvest time. Autoflowering plants have a much shorter life cycle than traditional photoperiod plants. They typically take between 8-10 weeks from seed to harvest, compared to 12-14 weeks for traditional photoperiod plants. This means that you can harvest your plants much quicker, allowing you to enjoy your harvest sooner. 

Small Size 

Autoflowering plants are typically much smaller than traditional photoperiod plants. This makes them ideal for those who have limited space or who want to grow their plants discreetly. Autoflowering plants are also easier to manage due to their smaller size, making them a good option for beginners. 

Continuous Harvest

Because auto flowering plants have a shorter life cycle, you can harvest them multiple times throughout the year. This allows you to have a continuous supply of cannabis without having to wait for a long time between harvests. 

Cons of Autoflowering Seeds 

Lower THC Levels 

One of the biggest drawbacks of autoflowering seeds is that they tend to have lower THC levels than traditional photoperiod plants. This is because auto-flowering plants have a shorter life cycle, which means that they have less time to produce THC. However, this can be offset by growing high-THC auto flowering strains. 

Expensive Seeds 

Autoflowering seeds tend to be more expensive than traditional seeds due to their specialized breeding process. This means that you may need to spend more money upfront to get started.

Limited Yield 

Autoflowering plants tend to have a smaller yield than traditional photoperiod plants. This is because they are smaller in size and have a shorter life cycle. However, this can be offset by growing multiple plants at once or using techniques such as low-stress training to increase yield. 

Limited Control 

Autoflowering plants have a predetermined life cycle, which means that you have limited control over their growth. This can make it more difficult to achieve the desired plant structure or yield. 


Autoflowering seeds have both pros and cons. They offer a quick harvest time, small size, and continuous harvest, but they also tend to have lower THC levels, limited yield, and limited control over growth. Ultimately, the decision to use autoflowering seeds will depend on your personal preferences and growing goals. However, with the right techniques and strains, autoflowering seeds can produce high-quality cannabis that is just as potent as traditional photoperiod plants. 

If you’re still not convinced about the benefits of auto flowering cannabis seeds, you can always opt for feminised seeds. While auto flowering seeds offer the advantage of a faster growth cycle and ease of cultivation, feminized seeds provide the assurance of producingexclusively female plants, ensuring higher yields of potent buds. With a wide range of strains available in both auto flowering and feminized seeds, it’s worth considering your growing preferences and needs to choose the right seeds for your unique situation.
