What are Autoflowering Cannabis Seeds? 

As the name suggests, autoflowering cannabis seeds automatically switch from vegetative state to flowering without the need to change its photoperiod or light cycles. Unlike the regular type of seeds, they flower based on their age and not due to the light exposure that you may put them through.  

They are fast-growing plants that come from the wild cannabis variety called Ruderalis. These plants only need around 7-12 weeks to be ready for harvest and can be kept short for easier growing. These type of seeds are also best to be used by novice breeders since they are pretty resilient to the common molds and mildew. The types of cannabis that usually have autoflowering seeds are known to have a higher CBD content than THC, making them ideal to grow for medical purposes 

Why choose Feminized Seeds? 

There are so many advantages of choosing feminized seeds as opposed to the regular ones. This is mainly to eliminate the likelihood of having to grow male plants that ultimately have to be thrown out since they don’t provide any buds to harvest. Another great advantage to these seeds is their lesser chance of growing hermaphroditic plants which are also next to useless come harvest. 

When choosing autoflowering feminized seeds, you’ll get the combination of the best of both worlds. You’ll have the advantages of not having to care or worry about having male plants and have the fast and easy cultivation that autoflowering seeds provide.  

 How to Grow Autoflowering Feminized Cannabis Seeds 

Even with the low maintenance of autoflowering seeds, there are still a few things that you will have to do in order to ensure that they grow to their maximum yielding potential. You will still need to figure out the best growing medium to place them on as well as the nutrients you’ll give them and the light exposure that you’ll put them through. 

The right type of soil for autoflowering strains 

There are many growing mediums out there for cannabis cultivation and most of them will do alright for your autoflowering seeds. However, the best type of medium for you to use is light soil with not that much nutrients than the normal potting soil that you can get in the store. This is to allow the plants to grow to their best potential and not get overfed in nutrients early on causing them to get nutrient burn.  

With the small stature of these plants, if you are up to it, you can also use hydroponics to grow them. It will require a bit more work on your part that autoflowering plants usually eliminate, but the quality of the cannabis buds you’ll be yielding through this method will be as outstanding as when you use light soil.  

The right nutrition for autoflowering strains 

Unlike conventional cannabis strains, autoflowering strains don’t really need as many nutrients to grow to its full potential. The best thing to remember when adding in nutrients to these plants is to do so sparingly.  

Once you’ve germinated the seeds, the seedlings won’t need anything else but water for the first 2 weeks. After that 14 day mark, you can start adding in a small amount of light grow nutrients to the plants. Remember that you should introduce these nutrients to the plants slowly and increasing bit by bit until you can stay consistent which is around their 6-week mark. Don’t forget to switch the fertilizers out for the best flowering ones when the buds start to bloom.  

The right light exposure for autoflowering strains 

Since autoflowering strains don’t rely on their photoperiod to flower, they can easily survive with as little as 5 hours of light exposure on a 24 hour day. However, this shouldn’t be so if you want to gain the cannabis plants maximum potency and yield potential.  

If you are growing indoors, the best light exposure for cultivation would be a 20-4 hour schedule that is kept consistent. Of course, you can also opt to go for 18-6 and 20-2 or even 24 hours consistent light exposure but the best practice is the 20-4. 

If you plan on growing outdoors, autoflowering strains are a great choice since there is minimal maintenance and can be grown short for privacy. You can start growing them even at springtime but are more recommended to be germinated and kept indoors under artificial light for at least 2 weeks. All you need is a warm and sunny environment and you’ll be able to harvest these plants with no problems.  

The right training techniques and pruning for autoflowering strains 

If you are asking how pruning and training techniques will affect your autoflower strains, then the answer is they’ll respond great! One of the best methods to use is low-stress training or LST. Early topping and pruning can also help boost your yields greatly. Another way to promote maximum yield potential is the Screen of Green Method. Although if you are going for a high volume cultivation, the Sea of Green is more recommended.  

If you plan to bend the plants to make flatter canopies, you won’t have to worry since this won’t stress out your plants too much to hurt your yield. If you are a beginner breeder, it is best not to experiment too much on pruning and trimming until you gain more experience to keep your plants happy and healthy.  

The right thing to do before harvesting autoflowering plants 

In about two weeks before your colas are ready to harvest, the most important thing you’ll have to do is to flush the plants out of their nutrients to have untainted buds. This is critical to be able to taste the full terpene profile of the cannabis that you are growing. This can be easily done with just plain water or a light flushing solution.  


With so many cannabis seeds out there, it is important to choose the right type of seeds that will best suit your breeding needs. Autoflowering feminized seeds are varieties that are fast and easy to grow and don’t have any male plants in them. How to grow autoflowering feminized cannabis seeds are as important to know as what they are. The light exposure, training techniques, and type of growing medium are all important if you want to be able to harvest the best yield possible.
