What Is an Autoflower Seed?
Autoflower seeds are a specific type of seed option for marijuana cultivation that offers several unique benefits that set them apart from traditional cannabis plants.
Autoflower seeds are the result of crossbreeding Indica dominant strains or Sativa varieties with Cannabis Ruderalis, a naturally occurring cannabis subtype found in Siberia and Northern Europe.
One of the most crucial features of autoflower seeds is the fact that they enter the flowering stage without making any changes to light cycles.
This is unlike feminized or photoperiod strains, where changes to the light cycle need to be made for the plants to move from the vegetative stage to the flowering stage.
From an autoflower seed, you can get both male and female plants, while feminized seeds and photoperiod strains grow only into female plants.
What is the Difference Between Regular, Autoflowering, and Feminized Seeds?
Regular cannabis seeds that grow into female and male plants fall into the category of the most natural traditional cannabis strains. These photoperiod strains are created through the pollination between female and male plants.
When it comes to cultivating regular marijuana seeds, there is a 50/50 chance of getting female and male plants, and they are favored for their genetic purity simply because they have not been treated or modified in any way.
However, indoor growers need to rely on changing light schedules to make them move from the vegetative to flowering stages.
Autoflower seed varieties are truly a game-changer. More specifically, autoflowering cannabis strains transition to the flowering stage automatically and do not require specific changes made in a light cycle.
Autoflowering seeds can grow into both female and male plants, and they typically produce plants of smaller size, which is why they are the preferred choice of experienced indoor growers.
Feminized seeds always produce female plants, and they are known for having a bushier form, making them more suitable for outdoor growing. This leads to a much higher-yielding crop than auto-flowering crops, as there are no male cannabis plants to use up resources.

Why Buy Autoflower Seeds?
Let’s take a closer look at what makes autoflower seeds distinct from other types of cannabis and why they are a better choice for cultivators.
Ruderalis Genetics
Autoflowering cannabis seeds are created by crossing Indica and Sativa strains with Ruderalis, a Cannabis subtype.
When these cannabis strains were introduced in the early 2000s, they were known for their low THC levels. However, as improvements were made over the years to cultivation techniques, their potency has significantly improved.
Compact Size and Discreet Growth
Autoflower weed plants are compact, and they are a practical choice for many growers with limited space. This smaller size is perfect for cultivators who wish to keep their crops away from prying eyes.
Faster Harvests
One key advantage to autoflower varieties is their quick growing cycle. Autoflower seeds typically progress from seed to harvest within a short lifespan of roughly 9 weeks to 10 weeks, depending on environmental factors like humidity levels and light exposure.
Low Light Dependency
Unlike other types, autoflowering cannabis plants do not need a specific light cycle to reach the flowering stage.
Regardless of how much light they receive, they produce flowers at a certain set storage of growth. This greatly simplifies the growth process, especially if you do not have the right equipment for ideal lighting conditions.
Adaptability to Various Environments
These seeds thrive in diverse indoor and outdoor growing conditions, and they are generally considered hardy and adaptable. Their low-maintenance nature makes them a game changer for beginners in the world of weed cultivation.
Multiple Harvests Per Season
Another standout feature of autoflowering cannabis seeds is their capability to provide perpetual harvests. Because their flowering is tied to maturity rather than external factors like the light cycle, you can expect multiple successful harvests in a single season.
On average, most autoflower plants allow for two harvests per year, while certain strains may offer even more. This combination of efficiency and impressive yields makes them a rewarding option for growers.
Why is It Better to Buy Autoflower Seeds Online?
If you are wondering about who should choose an online seed bank instead of your local one, we have compiled a few good reasons.
When you buy online, you gain access to a broader range of high quality autoflower seeds to grow top quality cannabis. These are almost certainly more diverse than local options.
Online sites also feature more detailed product descriptions to help you choose the best autoflower seeds. Vendors that offer autoflower seeds Canada make it easier to compare prices and reviews to help you make more informed decisions.

How to Grow Autoflower Seeds?
Autoflowering seeds flower independently, but there are still a few crucial cultivation steps you need to be aware of. By avoiding the most common mistakes made by newbies, you will be able to produce healthy plants and a successful yield.
Germination Process
To germinate autoflower seeds, you need to soak them in lukewarm water for 12 to 24 hours to soften the shell and support the seedling stage. Next, transfer them between moist paper towels in a warm, dark location.
Sprouting will typically occur within two to seven days. When a small root appears, you can plant the seedlings into a more permanent growing medium like high-quality soil or coco coir.
Soil and Nutrient Requirements
Autoflower plants grow well in a soil mix that is light, and well draining, with the right amount and type of nutrients. These plants need fewer nutrients than other varieties, so avoid over-fertilizing.
Use milder organic nutrients and gradually increase amounts to support nutrient uptake as plants mature. Ensuring the right nutrients and environment will maximize the yield and quality of your harvests.
Light and Watering Schedule
Autoflower plants can flower without any changes to the light cycle, and they flourish under consistent light conditions. You should water the plants carefully by allowing only the top layer of soil to dry out between waterings to prevent root rot.
For healthy growth, it is also important to monitor humidity levels and provide proper care throughout the plant’s life cycle.
Pest and Disease Management
While autoflowers are hardy and resilient, they can still encounter problems like pests or diseases. To avoid this, you should carry out regular inspections. You can also apply neem oil to deter pests and ensure good ventilation to stop the growth of mold.
Harvesting Tips
Autoflower plants reach the flowering stage relatively quickly, typically within 9 weeks to 10 weeks, depending on the growing conditions. You should keep an eye out for signs that your plant is ready to harvest. These include darkened pistils and cloudy trichomes.
For a successful harvest, cut at the base, trim the leaves, and dry the buds in a dark, ventilated space for about seven days.
Choosing the Best Autoflower Seed Bank
With so many options available, selecting the right seed bank can feel overwhelming. We have made the process of choosing easier by outlining several factors that you need to check out to make the best choice.
Reputation of the Seed Bank
Start by assessing the reputation of the seed bank. Look for one known for providing high quality autoflower seeds and top-quality cannabis products. They should offer proper germination guarantees and reliable refund policies.
Variety of Strains
Any good seed bank should offer a diverse selection of cannabis strains, including feminized, regular, and autoflowering cannabis seeds. This variety allows you to choose autoflowering seeds that match your preferences and goals.
Customer Service
Customer support also plays a critical role when choosing a seed bank. Look for companies with multiple communication channels, knowledgeable staff to assist with inquiries and 24-hour support.
Return Policy
Finally, review the return policy. A reliable seed bank should offer full refunds for damaged shipments and provide germination guarantees.
This ensures the best conditions for your plants during each cultivation stage and helps you obtain the best autoflower seeds for successful growth.
