Autoflower vs Feminized Seeds – Demystifying the Cultivator’s Dilemma

The world of cannabis cultivation is a diverse and exciting one, filled with a multitude of options and choices for growers to make. Among these choices, the debate between autoflower and feminized seeds is one that has captured the attention of enthusiasts and horticulturists alike. In this blog post, we will delve deep into the complexities of these two types of seeds, exploring their differences, advantages, and how to choose the right one for your growing needs.

Autoflowering Seeds

Autoflowering seeds have taken the cannabis world by storm in recent years, and it’s easy to see why. These seeds are engineered to flower automatically, regardless of the light cycle. This means that you can enjoy multiple harvests per year, making them a favorite among outdoor growers. But what sets them apart from feminized seeds?

Genetic Background:

Autoflowering seeds typically have ruderalis genetics in their background. Ruderalis is a subspecies of cannabis that developed in regions with short summers and harsh climates. This genetic influence is responsible for the automatic flowering feature and the ability to withstand adverse conditions. The combination of ruderalis genetics with indica or sativa strains can lead to a wide range of flavor profiles and effects, providing growers with a rich palette of options.

Growth Patterns:

Autoflowering plants have a predefined life cycle, which generally lasts between 8 to 12 weeks. They tend to stay small in size, making them ideal for stealth or limited space cultivation. This compact size, coupled with their quick growth, means you can have multiple crops in a single growing season.

Light Sensitivity:

Autoflowers do not rely on light cycles to trigger flowering. They start flowering based on age or maturity, which usually occurs around the third or fourth week. This makes them highly suitable for regions with inconsistent or short daylight hours, as they are not dependent on specific light schedules.

Feminized Seeds

On the other hand, growing feminized cannabis seeds are the product of selective breeding to eliminate male chromosomes, ensuring that almost every plant grown from these seeds will be female. This is advantageous because only female plants produce the sought-after buds, making it a popular choice for indoor growers.

Genetic Purity:

Feminized seeds are bred from two female plants, ensuring that the resulting plants carry only female genetics. This guarantees a higher yield of resinous and potent flowers. The careful selection of parent plants in the breeding process can lead to specific desired characteristics, whether it’s a particular flavor, aroma, or THC content.

Photoperiod Dependence:

Unlike autoflowers, feminized seeds rely on changes in light cycles to transition from the vegetative stage to the flowering stage. This makes them well-suited for indoor environments where the light cycle is easily controlled. This light-dependent nature also allows growers to implement techniques like “scrogging” or “super cropping” for enhanced yields and plant control.

Time to Harvest:

Feminized plants can take longer to reach maturity compared to autoflowers, typically requiring 10-16 weeks from germination to harvest. However, they often produce larger yields. The extended growth period provides ample time for more significant bud development and can result in bigger, more robust colas.

Choosing the Right Seeds

Selecting the right type of cannabis seeds depends on various factors, including your growing environment, goals, and experience level.

If you’re a novice grower or have limited space, autoflowering seeds might be the better choice due to their shorter life cycle and compact size. They are forgiving and require less maintenance, making them a suitable option for those just starting in the world of cannabis cultivation.

Experienced growers with control over lighting conditions may prefer feminized seeds, as they can optimize the vegetative phase and potentially achieve higher yields. The ability to manipulate the light cycle and growth patterns allows for a more tailored approach to cultivation.

For those seeking frequent, smaller harvests throughout the year, autoflowers provide an attractive option. This is especially valuable for those who prefer a continuous supply of cannabis for personal or medicinal use.


In the autoflower vs feminized seeds debate, there is no clear winner. The choice between the two ultimately comes down to your personal preferences and growing conditions. Each type has its unique advantages and challenges, and the key is to align your choice with your specific goals and resources.

Autoflowering seeds bring rapid growth, adaptability to varying light conditions, and the possibility of multiple harvests. On the other hand, feminized seeds offer genetic purity, allowing for customization of flavors and effects, as well as the potential for larger yields.

Whether you opt for the automatic beauty of autoflowering seeds or the refined feminized strains, the world of cannabis cultivation offers endless opportunities for experimentation and growth. Happy growing!
