The Countries Renowned for Their Cannabis-Growing Expertise

Cannabis isn’t grown the same way everywhere. Climate, traditions and techniques shape distinctive styles. From California to the Moroccan mountains, some countries have developed genuine expertise. Here are the regions that have shaped the history and evolution of cannabis cultivation.

Key takeaways

• Some countries have become global benchmarks thanks to their climate and their expertise in growing cannabis.
• Local varieties, known as “landraces”, have had a strong influence on modern genetics.
• Growing techniques and regional traditions explain the diversity of aromatic profiles and effects.

California and North America: constant innovation

California, the birthplace of modern cannabis culture

California is often regarded as the epicentre of contemporary cannabis. As early as the 1960s and 70s, a genuine culture grew up around the plant in the region, and it is this very spirit that we try to share with you through Cali Weed.

Passionate growers began selecting the best genetics, experimenting with new methods and sharing their knowledge. This movement gave rise to varieties that have since become legendary and laid the foundations of modern cultivation.

Even today, California remains a benchmark for flower quality and innovation.

The United States and Canada: technological mastery

In North America, cannabis cultivation relies heavily on technology. Growers use controlled environments: LED lighting, precise humidity management, CO2 control and optimised growing media. This approach makes it possible to recreate ideal conditions all year round and achieve highly consistent quality.

Canada, particularly since legalisation, has developed large-scale growing facilities where every parameter is closely monitored.

The influence of breeders and genetic selection

Much of North America’s expertise is built on genetic selection.

Breeders cross different varieties to create new aromatic profiles and improve certain characteristics such as yield, resilience or cannabinoid content. This ongoing research has led to an immense diversity of varieties.

Today, a large share of the genetics grown around the world can be traced back to these breeding programmes.

Europe and the Mediterranean: an ancient tradition

Morocco, a global benchmark for resin

Morocco is one of the countries best known for its cannabis resin production.

In the Rif region, cannabis cultivation is deeply rooted in local tradition. For generations, growers there have produced a resin renowned throughout the world.

The traditional method relies on dry-sieving dried flowers. This technique collects the trichomes, the tiny resin glands rich in cannabinoids and terpenes. The result is pollen or hash and CBD resins with very distinctive aromas.

The Netherlands and the coffeeshop revolution

The Netherlands played a major role in spreading cannabis culture across Europe. In the 1980s and 90s, Amsterdam’s coffeeshops became a meeting point for enthusiasts from all over the world. This environment encouraged the emergence of many breeders and seed banks.

Dutch growers helped stabilise certain varieties and develop hybrids that have become essentials.

Even though local production remains limited, the Netherlands’ influence on global cannabis genetics is immense.

Switzerland and the rise of CBD

More recently, Switzerland has established itself as a major player in the CBD market.

Thanks to more flexible regulations, many Swiss producers have developed crops specialising in cannabidiol-rich hemp. The country has stood out for its strongly quality-focused approach, including controlled indoor cultivation, precise genetic selection and rigorous traceability.

These high standards have helped position Switzerland as a benchmark in the European CBD market.

Historic cannabis regions: a unique heritage

Afghanistan and traditional hash making

Afghanistan is famous for its cannabis varieties adapted to dry, mountainous climates. These plants naturally produce very abundant resin, ideal for making hash.

The traditional method involves collecting the resin directly from the flowers or sieving the dried plants to recover the trichomes. Afghan hash is often recognisable by its dense texture and deep aromas, sometimes spicy or earthy.

This tradition has influenced resin production in many other regions.

Jamaica and outdoor cultivation

Jamaica is another iconic region for cannabis cultivation. Here, the plant is mostly grown outdoors, in a tropical climate that encourages vigorous growth.

Jamaican cultivation is also closely tied to a cultural and spiritual dimension.

The varieties grown on the island are often prized for their intense aromatic profiles and highly expressive character.

Thailand and tropical varieties

Thailand also has a long history with cannabis. For decades, certain Thai varieties were highly sought after for their distinctive profile: tall, slender growth, exotic aromas and effects reputed to be energising.

These tropical plants were often used in breeding programmes to enrich cannabis’s genetic diversity.

Today, the country is seeing renewed interest in cannabis cultivation, with a new generation of growers rediscovering this botanical heritage.
