History of marijuana strains

Zamal, a legendary cannabis strain from Reunion

Zamal, cannabis from Reunion Island

Also Cannabis or marijuana strains is a plant that currently can be found in all corners of the world. There is clear evidence that the cannabis plant originated in the Eastern/Central Asian regions. Then, it spread to the Middle East, and afterwards, to both the African and American continents. marijuana strains

Over the centuries, through traveling and commercial activities, humanity established cannabis cultivation in areas where it didn’t grow naturally. A perfect example of this expansion is Zamal, the strain that reached Reunion Island and acclimatized to the point of growing spontaneously as a pure landrace for over two centuries.

Cannabis in Afghanistan

Afghanistan is a landlocked country in central Asia, wedged between the western foothills of the Hindu Kush and the deserts of Iran, is a country with one of the greatest traditions of cannabis cultivation and, more specifically, of hashish production. Since it is believed that cannabis originated thousands of years ago on the slopes of the Himalayas (home of the largest mountains in the world), today it seems obvious that this was one of the first places where this plant was cultivated in a controlled manner, although even now there is still some confusion as to what kind of varieties have been traditionally grown in this area, as well as the “emergence” of the Afghan genotype, or in other words, what we now refer to as Afghan varieties.

What is clear is that Afghanistan is one of the cradles of cannabis and especially of hashish, with a tradition that today represents what would probably be the world’s oldest in terms of the development of hash. In addition, and according to the UNODC, in recent years Afghanistan has become the world’s largest producer of this resin concentrate, surpassing Morocco and seeing the cultivation of cannabis gradually displace that of another traditional crop in the Golden Triangle area, that of opium.

Origins of cannabis cultivation

Where did cannabis originate?

Mankind and cannabis have maintained a close relationship throughout the History. Although scientific and archaeological evidenceallows us to estimate the date and place where it originated, it is difficult to establish its exact place – and time – of origin.

Critical Mass by Mr. Nice, a legendary cannabis strain

Mr. Nice Seedbank, a project by Shantibaba, Nevil and Howard Marks

Almost 20 years have passed since Mr. Nice Seedbank was founded in 1998 by Scott Blakey, Nevil Shoenmakers and Howard Marks. Scott and Nevil, former partners of Arjan Roskam in the Green House Seed Company, decided to share their strains by creating a new seed company that quickly earned its place in the market and which got the name of the alias of the third partner, Howard Marks. At the time when feminized seeds were entering the market and demand was increasing every day (in countries like Spain and thanks to grow shops people were starting to grow their own pot), Shantibaba (Scott) and Nevil developed some of the most popular genetics of that time, like Black Widow (their own version of the White Widow), Neville’s Haze, La Niña or the renowned Critical Mass.

The origins of Haze

What?s the story of Haze?

Haze is, probably, the most grown and renowned 100% sativa hybrid throughout the world. Its origins date back to the early 1970’s in the region of Santa Cruz, California (USA).During this time, two brothers known as the “Haze Brothers” (R. Haze and J. Haze) cultivated and crossed different cannabis lines using seeds of the best imported sativa strains, most times offered by their friend and neighbor Sam “The Skunkman”.It all began with a hybrid between a landrace sativa from Mexico and another landrace from Colombia. One year later, the best females selected from this hybrid were crossed with a landrace strain from southern India. Finally, the female offspring of this new hybrid was crossed again with a landrace male from Thailand.

The Origins of Diesel

Origins of Diesel cannabis strains

In recent years, Diesel strains have become, by their own merits, one of the most popular cannabis genetics, seeked by growers and users both for its intense and special taste and for its strong effect, mainly caused by THC contents which can exceed 20% in most specimens. As it often happens in the world of cannabis, the exact origin of this genetics is uncertain, although one of the most commonly accepted theories tells us that it’d be directly related to the Chemdog and, later, also to the OG Kush marijuana.

Therefore, to clarify the origins of Diesel we need to know more about the mythical Chemdog strain – often called Chemdawg – and how it reached the East Coast of the United States.

The origins of Skunk

The Skunk gene pool


Skunk from Sensi Seeds

The Skunk is, doubtless, one of the most widely known and grown cannabis strains worldwide. The Skunk marijuana is a poly hybrid between two Sativa landraces – Colombian Gold and Acapulco Gold – and an Afghani Indica purebred.

This legendary cannabis strain was developed during the early 70’s in California by a group of growers and breeders known as Sacred Seeds, leaded by Sam Skunkman.

During the 80’s Sam Skunkman brought the Skunk to Europe (Netherlands) and sold some seeds under the name of Cultivator’s Choice. The remaining stock of seeds was then bought by Neville Shoenmakers, owner of The Seed Bank, later to become the Sensi Seed Bank.

Today, the Skunk#1 is considered a stable and homogeneous plant, what explains why it is so oftenly used to develop new hybrids such as Haze x Skunk or Seedsman’s Hawaïan SkunkContinue reading 

The origins of Northern Lights

The history of Northern Lights

The Northern Lights cannabis strain is, probably, one of the most renowned and appreciated Indicas around the world.


Nortthern Lights plant bred by Neville for Sensi Seeds

Somehow, in 1985 the 100% Indica Northern Lights arrived Europe – Netherlands – from the Pacific North West – ending up in Neville Schoenmaker‘s hands, owner of Holland’s first marijuana seedbank, known as The Seed Bank (later renamed Sensi Seeds by its new owner). It is told that all plants given to Neville were females, but The Seed Bank soon had Northern Lights seeds available in its catalog, so…how did Neville create his NL lines? Continue reading 

The origins of Blueberry

About the Blueberry cannabis strain


Blueberry cannabis plant in Jamaica (Photo:

The renowned Blueberry cannabis strain – and the Blue family created from it – was developed in the USA sometime during the 70’s by breeder DJ Short.

This genetics is a blend of different strains. Firstly, DJ Short was tasting some landrace Sativas from Colombia, Mexico, Thailand and Panama. Two very special plants stood out over the rest: a Highland Thai – also known as Juicy Fruit for its sweet and tropical flavour – and a Purple Thai from Oregon – hybrid between Highland Oaxaca Gold and Chocolate Thai.

Marijuana strains

On the other hand, he had a very special Afghani male from California that, while not havieng the exquisite features of his Sativas, was perfect to cross with them and achieve more easy to grow plants than those pure breds, allowing the grower to have more control.

After  a hard work of breeding, DJ Short finally developed his two best known strains:  the Flo and the Blueberry. The Flo is a hybrid between Purple Thai and the Afghani male, while the Bueberry ia a cross between the Flo and the Highland Thai “Juicy Fruit”. In this way, the Blueberry has genes from the two best Sativas that he found and also genes from the valued Afghani male. Continue reading 

  It has been surprising to see how quickly the best automatics have become so popular so we followed a Think Different grow review by European grower ‘Tang’ to find out more.

Think Different

Think Different from Dutch Passion

see Different from Dutch Passion

Think Different is a sativa variety based on genetics from an exceptional phenotype of AK47.

“This Think Different is the second biggest auto I’ve grown.  The biggest was Dutch Passion’s AutoXtreme but that had more than twice the light above her.  The Think Different was very low odour until the last few weeks when she smelt of citrus and fresh grass….lovely.  The next time I grow this strain I will make sure I have more light available. The dry yield on this Think Different was bang on 6oz at 168 grams. She was grown under 200W of LED, LED is the only indoor grow technology which allows me to maintain cool grow room temperatures in the hot summer months.  Its also less expensive to run than an HPS, which makes it worth the extra purchase cost”.

“. The nutrients were Sensi Grow and Sensi Bloom from Advanced Nutrients. Every day I gave her 20 hours of light and 4 hours of darkness, this was the same for 75 days from start to finish.   Autofem genetics can flower under 20 hours of daylight, this gives them bigger colas than a photoperiod variety can achieve in the same time.  My team Different grew like a normal cannabis seedling, automatics look and seem like traditional cannabis at first.  I saw the first female flowers after 25 days.  It is strange to see cannabis blooming under 20 hours of daily light, but somehow automatics manage it.  Under 20 hours of light it takes about another 40-50 days to finish, so in total from seed to harvest is about 70-75 days, 10-11weeks”.

“Automatics use the 20 hours of daily light to grow faster than they could under 12 hours of daily light.  Week by week you can see the difference, the roots grow quickly and the plant development is surprisingly fast.  Growth of the side branches is rapid, they search out the light and you can see the plant expand with vigour.  The resin production starts to gradually increase from day 40-50.  On Think Different the smell odour and aroma were not too intense, I would say for the last 2 weeks you need to pay attention to the carbon filter.  By the end the hairs were starting to turn orange and the blooms had finished growing.  Feeding is easy, just understand when your plant is ready for stronger feed and slowly increase the nutrient concentration.  Its just like feeding a photoperiod variety, follow the same rules”.

“I can see why this strain has become one of their (Dutch Passions) customer favourites.  The yields are well above average, it’s a killer smokeand it’s easy-to-grow.
