  • Techniques for producing autoflower seeds include both self-pollination and cross-pollination.

Understanding Autoflowering Cannabis Seeds

If you’re new to the world of growing cannabis, you may be unfamiliar with the concept of autoflowering cannabis seeds. Unlike photoperiod cannabis seeds, autoflower seeds are genetically engineered to flower automatically after a short vegetative period. This unique trait makes them a popular choice for growers looking for a quick turnaround time and smaller plants.

Autoflowering cannabis seeds are the result of cross-breeding various cannabis plants, including ruderalis, an indigenous strain from Russia. These plants are adapted to survive in harsh climates with limited sunlight, so they’ve evolved to flower automatically in just a few weeks.

One of the biggest advantages of growing autoflowering strains is their short life cycle. In just 60-90 days, you can harvest a crop of small, but potent, buds. This makes them an ideal choice for growers who want to produce multiple harvests per year and don’t have the space or resources for larger plants.

Another advantage of autoflowering cannabis seeds is their ability to flower in any light cycle. Unlike regular cannabis plants, which require specific light and dark periods to flower, autoflowering strains will begin to flower regardless of their light cycle. This means you can grow them indoors or outdoors without having to worry about light leaks or light schedules.

Autoflowering strains also tend to be more resistant to pests and diseases than regular cannabis plants. This is because they’re bred to be hardy and resilient, making them a great choice for outdoor gardens where pests and disease can be a major issue.

Understanding Autoflowering Cannabis Seeds

Autoflowering cannabis seeds are different from photoperiod cannabis seeds in several ways. One of the most notable differences is their life cycle. While photoperiod cannabis plants require a specific light cycle to initiate flowering, autoflowering strains will begin to flower after a certain amount of time, regardless of light conditions.

Another difference is their size. Autoflowering strains tend to be smaller than other cannabis plants, making them a great choice for growers with limited space. They’re also easier to manage and less conspicuous, making them a great choice for discreet growing operations.

Finally, autoflowering strains tend to mature faster than photoperiod cannabis plants. This means you can harvest multiple crops per year, making them a great choice for growers who want to produce a lot of cannabis in a short amount of time.

Benefits of Breeding Autoflower Strains

One of the biggest advantages of breeding autoflower strains is the ability to create unique genetics tailored to your specific needs. By selecting parent plants with desirable traits, you can create a strain that is high-yielding, disease-resistant, and has a unique flavor and aroma profile.

In addition to creating a personalized strain, breeding autoflower seeds also allows for greater control over the growing process. By selecting for certain traits, such as faster flowering times or increased potency, you can create plants that are better suited for your growing environment.

Another benefit of breeding autoflower strains is the potential for higher yield and potency. By selecting the best traits from the parent plants, you can create a strain with strong genetics that produces more buds and has a higher THC content.

It is important to note that breeding autoflower strains requires some knowledge and experience in cannabis cultivation. However, with the right resources and guidance, anyone can successfully breed autoflower seeds and create their own unique strain.

Breeding Autoflower Strains

Understanding Autoflower Cross-Pollination

Autoflower cannabis plants are unique in that they automatically flower without requiring any changes in the light cycle. This characteristic makes them a popular choice for growers as they are easy and quick to cultivate. However, when it comes to breeding, autoflower plants require special attention to ensure genetic purity.

Autoflower cross-pollination is a common issue when trying to maintain genetic purity. Cross-pollination occurs when pollen from one plant fertilizes the female flowers of another plant. This results in a hybrid offspring with genetics from both parent plants. While this may be desirable in some cases, it can be detrimental when trying to maintain genetic purity.

If you’re planning on breeding autoflower strains, it’s important to isolate plants to prevent accidental cross-pollination. One way to ensure genetic purity is to grow your plants indoors in a controlled environment. This allows you to control the pollination and avoid any unwanted cross-pollination.

You can also physically isolate plants by using barriers such as walls or plastic sheets. Be sure to cover the plants completely, including the top and sides, to prevent any accidental cross-pollination. Another option is to stagger the planting times to allow for proper isolation of each plant.

Tip Be sure to label each plant to keep track of parentage and to avoid any confusion during the pollination process.

By taking these precautions, you can ensure that your autoflower strains remain genetically pure, allowing for consistent and predictable plant traits. It may require some extra effort, but the end result will be well worth it.

Techniques for Producing Autoflower Seeds

There are several techniques to produce autoflower seeds, including self-pollination and cross-pollination. The most common and easiest technique is self-pollination, which involves pollinating a female autoflower plant with male pollen that comes from the same plant. This technique ensures genetic stability and purity but only produces a small number of seeds.

Cross-pollination, on the other hand, involves pollinating a female plant with male pollen from a different plant. This technique can produce a larger quantity of seeds, but it also carries a higher risk of genetic variation and instability. It’s important to choose pollen from a healthy and genetically stable male plant to prevent unwanted traits from being passed on to the offspring.

To maximize seed production, it’s crucial to use the right environmental conditions. The temperature and humidity should be kept within a specific range, and the plants should be exposed to adequate light to promote growth and development.

Producing autoflower seeds requires attention to environmental conditions and choosing the right pollination technique.

DIY Autoflower Seed Making

In addition to buying autoflower seeds from reputable seed banks such as Seeds Here Now, you may also choose to make your own autoflower seeds at home. This can be a cost-effective way to expand your breeding program and create unique genetics. Here are the steps involved in DIY autoflower seed making:

Selecting Parent Plants

Before you begin, you must select the parent plants that will be used for breeding. Choose plants with desirable traits and good genetics to ensure that you produce high-quality seeds. Remember that autoflower crosses may not always exhibit the same traits as their parents, so be prepared for some variability.

Creating the Breeding Environment

Once you have selected your parent plants, you will need to create the ideal breeding environment. Separate the male and female plants to avoid accidental pollination, and carefully monitor the plants for optimal growth conditions. You may want to consider using a grow tent or other enclosed space to maintain control over the environment.


When it comes time to pollinate, there are two options: self-pollination or cross-pollination. For self-pollination, simply collect pollen from the male flowers and brush it onto the female flowers. Cross-pollination requires a bit more effort; you will need to collect pollen from a separate male plant and transfer it to the female plant’s flowers. Remember to only pollinate the female plants that you wish to produce seeds from.

Harvesting and Storing Seeds

After pollination, the female plants will begin to produce seeds. Allow the seeds to fully mature and dry on the plant before harvesting. Once harvested, store the seeds in a cool, dry place to maintain viability.

Making your own autoflower seeds can be a rewarding and cost-effective way to expand your breeding program. Just remember to carefully select your parent plants, create the ideal breeding environment, and monitor the plants throughout the process.
