Modern Breeding Techniques and the Evolution of Autoflowers


In the article “Modern Breeding Techniques and the Evolution of Autoflowers,” the focus is on the advancements in cannabis breeding that have led to the evolution of autoflower varieties. These strains, unlike traditional cannabis, do not rely on changes in lighting to trigger flowering. Instead, they flower based on time. The article explores how modern autoflowers have come a long way since their discovery nearly fifty years ago, and the role that breeding techniques have played in improving their quality and potency. While autoflowers may not always receive the same recognition as their photoperiod cousins, breeders are hopeful that their continued improvements will help change the narrative.

Modern Breeding Techniques and the Evolution of Autoflowers

Cannabis breeding has undergone a remarkable evolution in recent decades, thanks to modern breeding techniques. In the past, landrace varieties slowly spread across the world through smuggling routes. However, with advances in genetics, breeders are now constantly searching for the next big phenotype. One area of cannabis breeding that has seen significant development is autoflowers.

Cannabis Breeding Evolution

In the early days of cannabis breeding, landrace varieties were the norm. These varieties slowly made their way across the globe through the smuggling routes of the global cannabis flower trade. However, with advancements in genetics, breeders started to experiment with crossing different varieties to produce new and unique strains. This marked the beginning of the cannabis genetics renaissance of the late 1970s and early 1980s.

Autoflowers Defined

Autoflowers are a type of cannabis strain that does not rely on changes in light to trigger flowering. Unlike photoperiod-sensitive cannabis, which requires specific light cycles to induce flowering, autoflowers start to flower based on time. Most modern autoflowers are descendants of Cannabis ruderalis, a subspecies of cannabis that can be traced back to Central and Eastern Europe and Russia. These plants evolved to be less dependent on regular lighting intervals due to the harsh and unpredictable climate in their native regions.

Origins of Modern Autoflowers

The origins of modern autoflowers can be attributed to Canadian and Dutch breeders. These breeders, specifically Nevil Schoenmakers from Australia who emigrated to Holland, began experimenting with crossing C. ruderalis with indica and sativa varieties. Although they initially had limited success, autoflower strains eventually gained popularity in the Netherlands.

The Role of Dutch Breeders

Autoflower strains became prominent in the Netherlands due to the unique nuances of the underground Dutch cannabis culture. These strains offered growers the ability to cultivate outdoor crops that would finish early in September, beating the Northern European early spring cold. Over time, Dutch breeders perfected the breeding process for autoflowers, leading to the development of high-quality strains.

The Creation of Lowryder Strain

The next major milestone in the evolution of autoflowers came with the creation of the Lowryder strain by a breeder in the United States known as The Joint Doctor. This strain was a cross between Mexican C. ruderalis and Northern Lights from the Netherlands. Despite its low potency and short stature, the Lowryder strain gained interest from prominent growers, sparking further advancements in autoflower breeding.

Autoflower Advantages and Drawbacks

Autoflowers offer several advantages that have contributed to their popularity. One of the main advantages is their expedited growing season, as they can reach maturity from seed in as little as seven weeks. This quick turnaround time is unheard of for photoperiod strains. Autoflowers also tend to be short and stocky in stature, making them ideal for growers with limited space. These strains are also capable of withstanding the elements, which is a crucial factor for outdoor cultivation.

However, there are drawbacks to growing autoflowers. Smaller plant size often results in smaller yields compared to photoperiod strains. Additionally, autoflowers can only be grown from seed, which means that phenohunting and cloning are not possible. The inability to clone autoflowers restricts growers from keeping a particular strain as a mother plant for future cultivation.

Improvements in THC Levels

Historically, autoflowers had lower levels of THC compared to photoperiod strains. However, modern breeding techniques have led to significant improvements in autoflower genetics. This has resulted in higher levels of THC in autoflower strains, making them more desirable among cannabis consumers. The increased potency, coupled with the quick turnaround time, has driven the demand for autoflowers in the market.

Autoflowers in the Market

As the demand for autoflowers continues to grow, breeders and genetics companies have responded by introducing a wide range of autoflower-specific brands. These brands specialize in producing high-quality autoflower strains that offer unique flavor profiles and potent cannabinoid percentages. The market is now filled with various autoflower options, giving consumers a diverse selection to choose from.

The Potential of Autoflowers

Modern Breeding Techniques and the Evolution of Autoflowers

With the ongoing advancements in modern breeding techniques, the potential of autoflowers is vast. As more breeders experiment and refine their breeding processes, autoflowers are likely to become even more potent and offer a wider range of flavors and effects. Additionally, the ability of autoflowers to thrive in different growing conditions makes them a versatile choice for both outdoor and indoor cultivation.


The evolution of modern breeding techniques has played a significant role in the development of autoflowers. Through the efforts of Dutch breeders and advancements in genetics, autoflowers have evolved into high-quality strains that rival their photoperiod counterparts. The ability of autoflowers to flower based on time rather than changes in light has made them popular among growers for their quick turnaround and ease of cultivation. With ongoing improvements in THC levels and the increasing market demand, the potential of autoflowers in the cannabis industry is promising.
