For many years, Dinafem Seeds was one of Spain’s best-known seedbanks and helped shape the development of feminized cannabis seeds in Europe. Founded in the Basque Country in 2005, the brand gained international recognition with strains such as Moby Dick, Critical+ and Critical Jack. After approximately 15 years, Dinafem’s previous business operations ended in 2020. Yet the story of its genetics continued: in 2021, Silent Seeds emerged as a new, independent seedbank founded by former Dinafem team members. Alongside selected classics, Silent Seeds develops new strains and collaborations. How did Dinafem’s success story begin, and what connection does it have to Silent Seeds today?

What was Dinafem Seeds?

Dinafem Seeds was one of Spain’s best-known cannabis seedbanks and one of the influential brands in the European seed market. Founded in the Basque Country in 2005, the company initially specialized in feminized cannabis seeds and steadily expanded its range over the following years. With well-known strains such as Moby Dick, Critical+ and Critical Jack, Dinafem reached an international customer base and established itself far beyond Spain.

Alongside classic photoperiod strains, Dinafem later developed and sold autoflowering cannabis genetics and CBD-focused lines. Its range included proprietary selections, further developments of established strain families and genetics with different breeding origins. Particularly during the 2000s and 2010s, Dinafem helped make feminized cannabis seeds accessible to a wider international market.

Dinafem’s founding and early years

The history of Dinafem Seeds officially began in 2005 in Spain’s Basque Country. The founding team had already spent considerable time working with cannabis genetics, plant breeding and the development of feminized cannabis seeds. The aim was to offer selected genetics in feminized form and build a proprietary range characterized by careful selection and the most consistent strain traits possible.

During its early years, Dinafem focused mainly on feminized versions of established cannabis lines. At the time, feminized seeds were becoming increasingly important in the European market. Dinafem embraced this development and gradually expanded its offering with its own crosses and selections. Strains such as Moby Dick and Critical+ became names closely associated with the Spanish seedbank.

Dinafem and the rise of Spanish seedbanks

During the 2000s, Spain became an important hub for the European cannabis seed industry. An active growshop scene, international breeder contacts and rising demand for feminized cannabis seeds created favorable conditions for new seedbanks. Alongside established Dutch suppliers, Spanish brands increasingly gained international visibility.

Dinafem was among the seedbanks that played a major role in this rise. The brand combined established genetic families with its own selections, continually expanded its range and reached customers in numerous countries through international distributors. Dinafem’s significance lay not in inventing feminized cannabis seeds, but in developing and popularizing them and establishing well-known strains within the European market.

Which cannabis strains made Dinafem famous?

Moby Dick and Critical+ are among the best-known strains in Dinafem’s history. Both names were associated with the Spanish seedbank for many years and contributed substantially to its international reputation. Moby Dick originated from a combination of White Widow and Haze genetics, while Critical+ drew on the established Critical family. Dinafem later added Critical Jack, a cross combining Critical and Jack Herer genetics.

The historic Dinafem catalog also included strains such as Original Amnesia, White Widow and OG Kush. It is important to distinguish between the original source of a cannabis genetic line and a seedbank’s own selection or further development. Some internationally familiar strain names existed long before they appeared in Dinafem’s range. A seedbank’s contribution may therefore involve developing new crosses as well as selecting, stabilizing and maintaining existing genetic lines.

Feminized seeds, autoflowers and CBD genetics

Feminized cannabis seeds were among Dinafem Seeds’ main priorities from the outset. These seeds are specifically developed to produce female plants with a high probability. Unlike regular cannabis seeds, which may produce both male and female plants, feminized seeds offered more predictable strain selection. Dinafem focused on selecting established genetic lines and helped further establish feminized strains in the European seed market.

As autoflowering cannabis strains became more important, Dinafem expanded its range to include autoflowering genetics. Unlike photoperiod plants, these begin flowering largely independently of daily light duration. In addition to new crosses, autoflowering versions of familiar strain families emerged. The seedbank thus responded to growing demand for different seed types and genetic traits.

During the 2010s, CBD-rich cannabis genetics also gained prominence. With its Dinamed line, Dinafem developed a dedicated range in which the targeted selection of specific cannabinoid profiles played an important role. Its expansion into autoflowering and CBD genetics shows how Dinafem evolved from a specialist in feminized seeds into an internationally known seedbank with diverse breeding priorities.

The end of Dinafem in 2020

After around 15 years, Dinafem Seeds’ previous business operations ended in 2020. This brought an important chapter of the Spanish cannabis seed industry to a close. Over the years, Dinafem had established an international presence with well-known strains such as Moby Dick, Critical+ and Critical Jack, alongside an extensive range of feminized, autoflowering and CBD-focused genetics. The brand disappeared from the market in its previous form, but many of its strain names and breeding lines remained widely recognized.

What remained of Dinafem’s genetic legacy?

When a seedbank closes, its genetics, selection experience and breeding knowledge do not necessarily disappear. Well-known Dinafem strains such as Moby Dick and Critical+ had secured an established place in the international cannabis scene over many years. Their names remained closely linked to the Spanish seedbank’s history even after 2020.

Another important part of that legacy was the knowledge of the people behind Dinafem. Years of experience selecting, crossing and developing cannabis genetics provided a foundation for new projects. While the original seedbank had ceased operations, former team members had new opportunities to build on familiar genetic families and pursue their own breeding ideas.

Silent Seeds: A new chapter from 2021

In 2021, Silent Seeds emerged as a new, independent Spanish seedbank, founded with the involvement of former Dinafem team members. The new brand built on years of cannabis breeding experience and combined selected classic genetic families with new crosses and modern breeding projects. This created a clear personal and breeding-related link between Dinafem’s history and the development of Silent Seeds.

Silent Seeds’ current range includes further developments of well-known strain families such as Moby Dick and Critical, as well as newer genetics and international collaborations. Its work with Sherbinskis in particular shows that Silent Seeds does not focus exclusively on former Dinafem classics but also pursues its own direction in modern cannabis breeding. An overview of available strains can be found in the Cannapot category Silent Seeds – Dinafem 2.0.

Silent Seeds and Dinafem 2.0: What is the connection?

Silent Seeds is often described as “Dinafem 2.0” because former Dinafem team members are involved in the new seedbank and selected well-known genetic lines are being continued. The term therefore mainly describes the personal connection and continuity of breeding expertise. Silent Seeds is nevertheless an independent brand that focuses not only on classic strain families but also on new crosses, its own selections and international collaborations.

For long-time Dinafem followers, the further development of familiar names is particularly interesting. Strains such as Moby Dick and Critical appear again in newer versions, linking the former seedbank’s history with Silent Seeds’ current range. At the same time, the new brand follows its own breeding direction. “Dinafem 2.0” is therefore an understandable description of this connection, but it does not mean that all current genetics are unchanged versions of historical Dinafem strains.

From Dinafem classics to modern Silent Seeds genetics

Silent Seeds’ current range combines familiar genetic families from Dinafem’s history with new crosses and international collaborations. While strains such as Moby Dick, Critical 2.0 and Critical Jack recall the former seedbank’s classic lines, newer developments such as Lemon Tree 2.0 and the Sherbinskis Selection reflect Silent Seeds’ independent direction. The following eight strains from the Cannapot range illustrate this development from established cannabis genetics to modern hybrid lines.

The overview highlights the diverse genetic roots of Silent Seeds’ current range. While Moby Dick, Critical and their variants connect to Dinafem’s earlier history, Lemon Tree 2.0 and the Sherbinskis selections represent newer developments. Historical strain versions and current developments can differ genetically despite similar names. The information for the specific version is therefore always essential when assessing a strain’s exact parentage.

How does Silent Seeds differ from Dinafem today?

While Dinafem became known primarily for feminized cannabis seeds and the development of internationally recognized strain families, Silent Seeds combines that breeding legacy with its own modern direction. The new seedbank draws on the experience of former Dinafem team members, continues selected classic genetics and simultaneously expands its range with new crosses and collaborations.

A particularly visible example is its collaboration with Sherbinskis, a brand from the California cannabis scene best known for its association with modern Gelato genetics. Such projects show that Silent Seeds does not focus exclusively on Dinafem’s past but brings together different breeding traditions. Historical continuity remains an important part of the brand’s identity, while new strain developments and international partnerships shape its current profile.

Historical timeline: From Dinafem to Silent Seeds

The development of Dinafem and Silent Seeds spans several decades of breeding experience. Key milestones can be traced from early work with feminized cannabis genetics through Dinafem’s international establishment to the founding of Silent Seeds. The following timeline summarizes the most important stages.

What was Dinafem’s significance for cannabis breeding?

Dinafem was among the seedbanks that played a decisive role in shaping the European market for feminized cannabis seeds during the 2000s and 2010s. The Spanish brand combined well-known cannabis genetics with its own selections, developed new crosses and brought strains such as Moby Dick, Critical+ and Critical Jack to international prominence. In doing so, Dinafem contributed to the growing importance of Spanish seedbanks within the European cannabis seed industry.

The continuous expansion of its breeding priorities was particularly notable. Feminized photoperiod strains were followed by autoflowering versions and later CBD-focused genetic lines such as Dinamed. This development reflected changes in a market where different cannabinoid profiles, genetic characteristics and new strain families were becoming increasingly important.

Dinafem’s legacy therefore consists of more than well-known strain names. Equally important are its experience in selection and breeding and the international reputation the brand built over many years. With the founding of Silent Seeds in 2021, a new project emerged that connects to parts of this history through former team members and selected classic genetic families while pursuing its own developments.
