The highest THC strains in the world

16 Nov 2018

What are the highest THC strains in the world?

We are often asked about what are the highest THC strains in our catalogue so thought it was high time we put an article together with some info on what THC is, how the strength has increased over the years and what strains have the highest levels of THC in the them

What is THC?

THC, also known as tetrahydrocannabinol, is the compound found in cannabis that has psychoactive properties and gives you the feeling of being high. According to the National Institute on Drug Abuse (NIDA), THC has an affect on things like thinking, memory, pleasure, movements, concentration, coordination, and sensory and time perception. For these reasons it is recommended that people should not drive or operate heavy machinery when under the influence of Marijuana. Aside from these physical and mental affects THC has been shown to offer many health benefits including helping people suffering from PTSD, eating disorders, anxiety, depression and anxiety. Back in the 60's when people tended to smoke 'grass' with pollinated flowers full of seeds THC levels were around 1%. With the advent of the creation of new hybrid cannabis strains in the 90's such as Skunk no.1 and Afghan Kush, THC levels jumped massively to around 10%. Then as cannabis laws relaxed around the world and breeders were able to experiment more freely in places like Holland, Spain and now the USA the boundaries of where THC levels can go have been pushed in the the high 20's and even over 30%!

Cannabis and its sub species

10 Sep 2012

what is cannabis? Cannabis  is a genus of flowering plants that includes three separate and distinct varieties, Cannabis sativa, Cannabis indica,and Cannabis ruderalis. These three sub species are indigenous to Central Asia, and South Asia. Cannabis has for 1000's of years been used for making hemp fibre, for food, for medicinal purposes, and as a recreational drug. Industrial hemp clothes and materials are made from Cannabis plants which have been selected to produce an massive amounts of fibere. To satisfy the UN Narcotics laws, industrial hemp varieties have been created which contain very low levels of THC (one of the psychoactive compounds that gives the "high" associated with smoking cannabis. The psychoactive product often called marijuana is the dried flowers of plants selectively bred and modified to produce high levels of THC and other psychoactive compounds such as CBD. Various extracts such as hashish and hash oil can also be produced from the plant.

cannabis sativa

Cannabis sativa is one of the subspecies of the cannabis genus. A Cannabis sativa plant can have a THC/CBD ratio 4-5 times that of Cannabis Indica, that is to say sativa strains have high levels of THC and in comparison low levels of CBD. The Plants are generally tall and slender characterised by narrow serrated leaves and loose spear-like flower clusters that can be extremely resinous. Sativa cannabis plants can often reach 2-3 metres in height and will have longer flowering times, taking between 10 and 14 weeks to reach full maturity. Sativas are well known for their cerebral high and primary effects that focus on the mind and emotions.

Cannabis Indica

Cannabis indica is a short and stocky genus of the cannabis genus which is thought to have originated in the Hindu kush mountain range of central Asia. Due to to the short harsh summers and variable weather cannabis indica strains have to finish fast often reaching maturity after 8 weeks of flowering and pack on huge flowers and buds which are covered in resin. Indica strains are much shorter and stockier than sativa strains generally being around 1 metre in height. Indica strains have a CBD/THC ratio that can be 4-5 times higher than sativa strains. This means that Indica strains have much higher levels of CBD than sativa strains. Indica strains are often used in the hindu kush region for the production of hashish and hash oils. Indica strains are well know for their medical benefits due to their narcotic and sedative effect.

Cannabis Ruderalis

Cannabis Ruderalis is a sub species of cannabis that originates from central Asia and is much shorter than cannabis sativa and cannabis indica. Ruderalis has developed in very harsh climates and begins flowering according to life cycle rather than photo period unlike the sativa and indica varieties. This means that  ruderalis plants will begin to flower after 3-4 weeks from germination unlike the sativa and indica sub specie which need to receive less than 12 hours of light per day to begin flowering. Because of these reasons Ruderalis has been described as 'auto flowering'. Ruderalis has very low levels of THC and CBD and has little recreational use but various breeders have crossed ruderalis with indica to create autoflowerinng strains with higher levels of THC and CBD while retaining the autoflowering trait.

Gender (sex) of cannabis plants

10 Sep 2012

Cannabis plants are either male or female. The male plants produce pollen which pollinates the flowers of the female plant, which once pollenised, produce seeds. If the female plant isn't pollenized (if there are no male plants nearby producing pollen), the flower/buds continue to develop and produce THC. Female plants which are not pollenized are referred to as sensemilla (without seeds). If a female cannabis plant is not pollenised it puts more effort into producing buds and excess resin. cannabis plant gender More in-depth information on the gender of marijuana plants Female Pistils - notice the sac and the feathery frond-like structure. Usually after five days to two weeks you will begin to see a pair of tubular nodes. Hopefully they will have white hairs protruding from them as this denotes a female plant. These little hairs are known as pistils and they are the first sign your plant is flowering. Female Cannabis – The female cannabis plant, unlike the male, is grown to produce marijuana. Premium marijuana is produced in seedless form by eliminating all pollen sources from the growing environment. Seed production reduces the value of marijuana dramatically by lowering the yield and potency of the flowers. The female flowers appear as two long white, yellow, or pink pistils protruding from the fold of a very thin membranous calyx. The calyx is covered with resin exuding glandular trichomes (hairs). Pistillate flowers are borne in pairs at the nodes one on each side of the petiole behind the stipule of bracts which conceal the flowers. The females are recognized by the enlargement of a symmetrical tubular calyx (floral sheath). They are easier to recognize at a young age than male primordia. The first female calyxes tend to lack paired pistils (pollen-catching appendages) though initial male flowers often mature and shed viable pollen. In some individuals, especially hybrids, small non-flowering limbs will form at the nodes and are often confused with male primordia. The female plants tend to be shorter and have more branches than the male.  

G13 – the cannabis legend

10 Sep 2012

G-13 is an extremely strong (i.e. very mind altering) strain of cannabis that is the subject of many urban legends Fact: This strain (originally a single clone) was probably of Afghani origin, and provided a very potent smoke. Fiction: According to one fanciful account, the CIA, FBI, and other agencies procured the best strains of marijuana from breeders all over the world. At an installation at the University of Mississippi, they bred many new hybrids. Putting these together, they created a strain that was more powerfully intoxicating than any of the original hybrids. Fact: Although Cannabis researchers at "Ole Miss" assembled a world class Cannabis collection during the late 1960s and early 1970s, there is no evidence that these researchers were ever involved in breeding high quality marijuana. The standard drug strain that is available to qualified researchers in the U.S.A. was originally from Mexico. Fiction: Apocryphally, G-13 contains 28% THC by weight, about double the average percentage in most high-grade sinsemilla grown commercially. It has been claimed that some strains of marijuana grown in Amsterdam have met or surpassed this percentage, but accurate, verified results have not been produced. Also, no other species of the plant seems to have quite the consistancy of such high THC content. Fact: Cannabis researchers identify G-13 as an Afghani "indica" (or 'Afghanica') cultivar, high in THC (though not as high as the 'apocryphal' estimate above). Reports of THC/cannabinoid content exceeding 20% are invariably from sellers of Cannabis or Cannabis seeds, or from anti-Cannabis crusaders. Reliable testing has placed the most potent examples of Cannabis plant matter ever tested at around 18% or 19% (based on Dutch government testing of medicinal grade Cannabis) Unsubstantiated Rumors: Allegedly, a single cutting of this potent strain was "liberated" from the government facility in Mississippi. Other rumors say G-13 was developed by the university of Washington Cannabis testing facility for medical testing during the 1970s, but this too has not been verified. In the early 90's, the name G-13 was said to have come from the number of [backcross] generations it took to produce an almost perfect plant - however, this view has absolutely no basis in reality. The name G-13 is was derived from the term Government Marijuana, the 13 used as M is the thirteenth letter of the alphabet. The most common story about the naming of G-13 is that it was stolen from 'grow-room 13' and simply retained its lab ID code. Another fantasy-based rumour is that the name 'G-13' derives from the 'genotype' having been created to express 'the 13 most desirable qualities'. Again, this is just idle (and poorly thought out) rumour. Some seed banks (which are very unlikely to have genetic material from the original clone) describe this strain as the highest THC content ever. Other seed banks that are known to have actually worked with the clone since the mid-Eighties describe it as one of the strongest "indicas" ever discovered. G-13 in the Movies G-13 x White Widow hybrid The G-13 strain was featured in the film American Beauty. In the film, a young dealer named Ricky Fitts (Wes Bentley) hands a bag of what looks to be about an eighth (1/8 of an ounce, commonly 3.5 grams) to Lester Burnham (Kevin Spacey) and says, "This shit is top of the line. It's called G-13. It's genetically engineered by the U.S. Government. It's extremely potent, but a completely mellow high. No paranoia." He then charges him $2,000. This line is likely responsible for a boost in the strain's popularity. However, the actual dollar value of G-13 (non hybrid) ranges from $20.00-$25.00 for a single gram, equalling about $60.00-$85.00 for an eighth of an ounce. The High G13 gives a high unlike any other cannabis strain available. The onset is almost immediate, with noticeable effects occurring within the first five minutes. Most users who have never had the chance to indulge in this strain are awe-struck when they first experience it. While most cannabis strains will have a "peak," in which the high starts to wear off, this does not occur with G-13 (in a manner of speaking). Some people have described G-13 to be "an elevator that never reaches the top floor," meaning the high keeps going up, and up, and up and does not stop. Many users also report a great euphoria as well. Some of our strains with G13 in the genetic makeup:
