Before we dig much deeper into high THC pot seeds, we need to take a look at the primary strains of cannabis. This centuries-old herb is divided into three basic classifications: cannabis Sativa, Indica, and Ruderalis. Sativa and Indica are the ones you hear the most about, and they’re the ones growers and consumers are most interested in for their many benefits.
Cannabis Sativa stands out for several reasons. This strain originated in tropical regions near the equator, so it’s accustomed to long hours of strong sunlight and equal hours of darkness. It also craves ample heat and humidity.
Those equatorial origins have caused strains in the Sativa family to adapt their appearances accordingly. In their native regions, the light cycle doesn’t change much throughout the year, so they have longer growing cycles than other strains.
Having 12 hours of sunlight each day gives them plenty of time to draw in UV light to foster the photosynthesis process. Nights are equally lengthy in those tropical areas, so Sativas have grown accustomed to 12-hour periods of darkness as well. After the sun goes down, Sativas use the darkness as a resting period during which they use the nutrients and sunlight they take in during the day to create food.
Since Sativa strains have so much time to take advantage of nature, they naturally grow tall and streamlined. In fact, they can grow to 10 feet tall or more. Their leaves are typically slim, and their buds are wispy and loosely packed. You could easily get lost in a field of Sativa, but it’s difficult to hide when grown outdoors. Purebred Sativas aren’t necessarily the best varieties to grow indoors because of their inherent height.
In terms of cannabinoids, Sativas usually have higher levels of THC than other strains. High THC 420 seeds are bound to have at least some Sativa DNA in their gene pool. Of course, not all Sativas are considered high-THC strains. Some only contain minimal amounts of this compound.
Members of the cannabis Indica family hail from mountainous regions and more moderate climates rather than tropical areas. They enjoy heat and light, but they also need cooler nights. In light of their origins, they seek out a more varied light cycle.
In areas where Indica grows naturally, the growing season starts out with long days and shorter nights. This is the pattern Indicas need during their vegetative states. During the natural transition from summer to fall, though, days become shorter and nights grow longer. At that point, the cycle converts to 12 hours of daylight followed by 12 hours of darkness. This shift signals Indicas to begin their flowering phases.
Considering their innate genes and customary growth cycles, Indicas don’t get quite as tall as Sativas. They usually grow no more than four feet tall at maximum, and their buds are shorter and denser than those of Sativas. Indicas can more easily be hidden in an outdoor garden because of their small stature. They’re more suitable for indoor growing as well.
Indica strains have diverse THC levels. Some have higher amounts of this psychoactive compound whereas others contain greater concentrations of CBD. In some cases, they have almost equally balanced amounts of both compounds.
Unlike Sativa and Indica strains, Ruderalis was never carefully cultivated during its early days. It sprouted naturally in various areas and developed its own unique set of traits. For the most part, Ruderalis grows in harsher climates where other strains probably wouldn’t thrive.
Ruderalis grows in parts of Russia, Asia, and Europe. It flourishes in regions with cooler temperatures, shorter days, and brief growing seasons. In those areas, it doesn’t have the benefit of long periods with plenty of sunshine as other strains do.
Because of its heritage, it adapted in the best way it knew how. It began flowering based on its age rather than the light cycle. This makes it an autoflowering strain as opposed to a photoperiodic one like Sativa and Indica.
Those growing conditions caused Ruderalis to evolve into a much smaller plant than its relatives. In most cases, it grows to no more than two and a half feet tall. It’s also much more tolerant of less-than-ideal growing environments and more resilient to pathogens.
Its small size and hearty nature make Ruderalis a nice option for indoor growers and those who are new to cannabis cultivation. Having said that, it’s not one of the most potent THC strains. In fact, Ruderalis usually has little THC if any at all. Though it contains some CBD, its concentrations aren’t as high as those of other strains.
Now that we have the three basic cannabis strains under our belts, we can venture outside the box. High THC marijuana seeds as well as other varieties aren’t all purely Indica, Sativa, or Ruderals. For quite some time, breeders have been experimenting with combining the genetics of various strains to create entirely new ones.
Hybrids are made by crossbreeding different strains of marijuana. Breeders consider the genetic traits, effects, and other strong suits of different strains. Then, they bring together the ones with the most desirable characteristics to develop even better alternatives. At this point, nearly 800 strains have been developed, and more are continually being added to the mix.
Crossbreeding cannabis involves allowing male plants from one strain to pollinate female plants of another. The resulting offspring carry the genes of the two parent plants. Of course, the world of botanical reproduction isn’t exactly straightforward.
Some offspring of the hybridization process exhibit all the traits breeders are looking for while others don’t. In certain isolated incidents, some offspring actually exceed breeders’ expectations, and those become the focus of further attention. In most cases, though, the progeny that don’t carry over the desired genes are simply scrapped.
Hybrids that make the cut are crossbred with each other to stabilize their genes and ensure the chosen traits and effects are passed along to future generations. Some are crossbred with additional strains to create even greater diversity.
