The development of modern American marijuana strains began in the United States during the 1960s and 1970s. It was during this time that Californian surfers, the hippie and underground movement, and American soldiers returning from their travels through Asia, Africa, and Latin America brought with them landrace genetics, also known as pure local cultivars. These original strains became the foundation for the development of modern hybrids, laying the groundwork for what we now know as USA strains.
The classic genetics and landraces collected from various regions of the world were hybridized, either intentionally or accidentally, giving rise to iconic American marijuana strains. These hybrids revolutionized global cannabis culture, positioning the United States as a benchmark in cannabis genetic innovation.
Kush
Kush strains have their roots in the Hindu Kush mountain range, a mountainous region spanning Afghanistan, northwest Pakistan, and northern India. These plants are characterized by their Indica structure, with strong stems, compact branches, and dense, resinous buds, making them ideal for short flowering cycles.
During the 1960s and 1970s, surfers, hippies, and American soldiers brought Kush seeds from Asia to the United States. This cultural and genetic exchange marked the beginning of the selection and hybridization of these strains on American soil, renowned for their potency and uniqueness.
One of the most iconic strains of the American Kush family is OG Kush, developed in California in the 1990s. With a lineage that combines Chem Dawg and a cross between Lemon Thai and Old World Paki Kush, OG Kush became one of the most sought-after strains on the market. Its name, "OG," stands for "Ocean Grown," a nod to its Californian origin.
San Fernando Lemon Kush® (SWS62) is an outstanding USA strain that inherited the intense lemon essence of the original OG Kush, alongside the magnificent Purple Punch OG® (SWS93) and Killer Kush Auto® (SWS56), both flavorful and aromatic strains with Kush genetics originating from the USA.
Kush Characteristics
- Lineage from the Kush Family: Afghani, Pakistani and North Indian
- Effects: Relaxation, euphoria, happiness, sleepiness
- Aromas: Sweet, fruity, woody, spicy, coffee, lemon, cypress
Skunk
Skunk is one of the most iconic and widely grown cannabis strains in the world. Developed in the early 1970s in California by the Sacred Seeds collective (of which Sam the Skunkman was a member), this strain is a polyhybrid that combines landrace Sativa genetics like Acapulco Gold and Colombian Gold with an Afghan Indica landrace.
In 1985, Sam the Skunkman brought Skunk #1 and other Californian genetics to Amsterdam, making it the first hybrid strain to be commercialized in the Netherlands. This transition marked a turning point in cannabis culture and established USA seeds as a global reference. Skunk #1’s traits, such as fast flowering, dense and compact buds, and high trichome production, made it ideal for hybridization and the genetic improvement of other strains.
Today, Skunk remains one of the most recognized USA strains, thanks to its ability to thrive in both indoor and outdoor grows, and for offering a perfect balance of potency, flavor, and yield.
Our renowned and award-winning Green Poison® (SWS14) and its sister strains Green Poison Auto (SWS30), Green Poison XL Auto (SWS71), Green Poison F1 Fast Version (SWS41) and Red Poison Auto (SWS39), are among our finest representatives of this legendary genetic family.

Haze
During the 1960s and 70s, the United States saw an influx of tropical Sativa strains from regions such as Southeast Asia, Colombia, and Mexico. These strains, known for their long flowering times, intense aromas, and stimulating effects, came to be generically referred to as Haze.
The Haze strain was developed in the mid-1970s in Corralitos, a small town in Santa Cruz County, California, by the famous “Haze brothers.” These breeders and collectors of cannabis genetics dedicated themselves to sourcing and crossing the best Sativas they could find, originating from countries like Mexico, Colombia, India, and Cambodia. From their work came Haze and Original Haze: strains that mainly incorporated Colombian and Mexican genetics and quickly became foundational pillars of modern USA strains.
In the same town, just a few streets away from the Haze brothers, lived Sam the Skunkman, a member of the Sacred Seeds collective. He received seeds from them and later brought these genetics to the Netherlands. Most of the Haze seeds and Haze hybrids we know today likely stem from Neville Schoenmakers, founder of the Dutch seed bank The Seed Bank of Holland, who specialized in refining and distributing these genetics worldwide. Both Sam and Neville played a crucial role in expanding USA seeds and establishing them as global benchmarks.
At Sweet Seeds®, we have a very special selection of Haze, our Sweet Amnesia Haze® (SWS72), released in 2018, which is also available in its autoflowering version, Sweet Amnesia Haze XL Auto® (SWS57).

Northern Lights
Northern Lights is one of the most iconic and recognized Indica strains of all time. According to cannabis expert Jorge Cervantes, this legendary strain was developed in the United States in the late 1970s by a grower known as “The Indian,” who preserved 11 numbered female clones, from #1 to #11. Among them, Northern Lights #5 stood out as the most valuable and widely used, becoming the foundation for many modern cannabis genetics.
In 1985, these 11 clones were brought to the Netherlands by Nevil Schoenmakers, founder of The Seed Bank of Holland, the first Dutch seed bank. There, Northern Lights was crossed with other genetics, such as Haze, giving rise to legendary hybrids like Northern Lights #5 x Haze. Although the original Northern Lights genetics may have been diluted through countless crosses, its legacy lives on in many of today’s American and Dutch cannabis strains.
Northern Lights Main Characteristics
Northern Lights is known for producing robust, bushy plants with abundant side branches and large, dense, resinous buds. These traits made it a perfect choice for hybridization, especially for strains suited to indoor growing. Its main features include:
- Fast flowering: With a flowering period of no more than two months, it’s ideal for growers seeking quick results.
- Short internodal distance: Promotes compact growth.
- High trichome production: Results in potent, resin-heavy buds.
Thanks to these characteristics, Northern Lights contributed to the development of legendary hybrids like Super Silver Haze, Sour Diesel, and Shiva Skunk, cementing its place as one of the most influential USA strains in cannabis history.
Northern Lights Characteristics
- Lineage from the Northern Lights Family: Afghani, Thai
- Effects: Relaxing, sense of well-being
- Aromas: Woody, earthy, sweet, spicy
- Flowering: Usually features a flowering stage of no more than two months
Northern Lights is not only a cornerstone of American cannabis genetics but also a lasting icon in global cannabis culture. Its genetics remain a benchmark for breeders and growers seeking high-yielding strains with deeply relaxing effects.
Chem Dawg, Diesel, and OG Kush
Chem Dawg, Diesel, and OG Kush are among the most influential and recognized genetics in cannabis history. These USA seeds, primarily developed in the United States during the 1990s, have given rise to an extensive family of hybrids that have taken the global market by storm thanks to their potency, aroma, and versatility.
The Origin of Chem Dawg
The Chem Dawg lineage traces back to a small garden in Colorado, where a grower nicknamed "The Old Man" spent years crossing the best plants from his harvest to develop this iconic strain. It is believed that its ancestors included Indica genetics such as Kush or Northern Lights, crossed with Mexican or Thai Sativas. In the early 1990s, this genetic line made its way to Massachusetts, where a few seeds recovered from a package of Chem Dawg cannabis were germinated. One of these seeds produced the original elite clone that would become the foundation of the Diesel family.
The Diesel Family Evolution
On the East Coast, growers began crossing Chem Dawg with local genetics like Massachusetts Super Skunk and Sensi Northern Lights, leading to hybrids such as Original Diesel and later Sour Diesel, the result of accidental pollination. Sour Diesel quickly gained fame for its powerful aroma and energizing effects.
Meanwhile, on the West Coast, a Chem Dawg cutting made its way to California, where growers like “Putz” crossed it with strains such as Lemon Thai and Old World Paki Kush, giving rise to the legendary OG Kush. Known for its versatility and balanced effects, OG Kush went on to become the base for hybrids like Bubba Kush and Purple Kush, which remain cornerstones among modern USA strains.
Impact in Europe
By the late 1990s, Diesel genetics made their way across the Atlantic and reached the hands of the Dutch seed bank Soma Seeds. There, hybrids such as New York City Diesel (NYC Diesel) were created, blending Sour Diesel with Afghan and Hawaiian strains. These new hybrids not only conquered Europe but also played a key role in inspiring the development of countless new genetics worldwide.

Blueberry
Blueberry is one of the most iconic Indica strains in the world of cannabis, renowned for its sweet, fruity flavor, vibrant blue and reddish hues, and powerful relaxing yet euphoric effects. This American-born strain gained international acclaim in 2000 when it was awarded Best Indica at the High Times Cannabis Cup, solidifying its status as one of the most cherished genetics on the planet.
Origin and Development of Blueberry
Blueberry was created and developed in the United States during the 1980s and 1990s by legendary Canadian breeder DJ Short. A passionate grower with a background in biology and psychology, DJ Short combined exotic cannabis genetics with careful selection to shape what would become the Blueberry strain and the wider Blue Family.
To develop Blueberry, DJ Short worked with a selection of pure Sativas from Colombia, Panama, Mexico, and Thailand, as well as Afghani Indicas developed in California and Oregon. The key genetics involved in its creation include:
- Highland Thai (Juicy Fruit Thai): A pure Thai Sativa known for its fruity aroma.
- Purple Thai: A hybrid between Chocolate Thai and Highland Oaxaca Gold (H.O.G.), a Mexican Sativa.
- Afghani Indica: Contributed its compact structure and deeply relaxing effects.
Due to legal restrictions in the United States, DJ Short moved to Europe in the 1990s, bringing his seeds with him. In the Netherlands, a country renowned for its tolerant cannabis laws, he continued refining Blueberry, which quickly gained popularity across Europe and worldwide.
Strains from our catalog containing Blueberry genetics include Cream Caramel® (SWS04), Cream Caramel Auto® (SWS22), Cream Caramel F1 Fast Version® (SWS40), Black Cream Auto® (SWS37) and Cream Mandarine Auto® (SWS22).
