Often, when it’s time to buy cannabis seeds, the beginner grower can quickly become confused by some of the acronyms that are written next to the name of the variety. Simply by learning some basic concepts you’ll be able to make the correct choice between seeds with the same name, but different acronym.
Each variety expresses its genetic code (genotype) with a certain growth and flowering pattern (phenotype), so that pure varieties – with a purest genotype – show great uniformity, with just a few slight differences between phenotypes. We can expect very little variation between landrace specimens of the same variety, giving plants with very similar growth, organoleptic and psychoactive traits. Good examples of these varieties can be Hindu Kush (Sensi Seeds), Colombia Punto Rojo (Cannabiogen) or China Yunnan (Ace Seeds).
BX or Backcross
This technique is also used to replicate clones in seed form. It is done by choosing a male parent to cross with the clone only, backcrossing it as many times as needed to get an offspring as similar as possible to the original clone. The Apollo 13Bx (TGA Subcool) is an excellent example of this technique.
Also known as landraces or purebreds, pure cannabis varieties have been the basis of cannabis breeding over the past decades. These species are endemic to a geographical area, where they have developed without having been crossed (hybridised) with other varieties. There are a large number of landraces from all around the planet, belonging to any of the three families of cannabis, C. sativa, C. indica and C. afghanica. Nepal is a good example; in this country different pure cannabis varieties (mostly narrow-leaved mixed use varieties) are grown and you can easily see the differences between genotypes based on the height above sea level at which they are cultivated.
If we make a cross between two different landrace or IBL lines (parental A and B) with different genotypes, the resulting offspring will be the F1 hybrid, the first filial generation from the cross of the phenotype #1 (Parent A) with the phenotype #2 (Parent B). Commonly in this kind of crosses we will observe a very uniform offspring, depending on how stable the parents are, of course. The F1 hybrid between two pure varieties or IBL’s will show the so-called hybrid vigour – also known as heterosis or outbreeding enhancement – introducing new genes that will produce “better” specimens.
Many of the seeds that we can find in shops are polyhybrids, crosses between different hybrids. The offspring of such crosses are in many cases quite unstable, producing plants with very different traits. Keep in mind that in these cases, the genetic mix is very varied, so we can not expect polyhybrid offspring to be as homogenous as an F1 hybrid. It’s easy to imagine how complex it can be to stabilise a cross, since we are mixing different genes from different varieties, which makes the selection and stabilisation process of the different traits a very hard work. The vast majority of hybrids on the market are in fact polyhybrids, like the White Russian (Serious Seeds) or Fruity Jack / Jack el Frutero (Philosopher Seeds).
The term “hash plant” was originally used to define very resinous plants used in some parts of Asia for the production of hashish. Later, already in the 80’s, a variety created on the west coast of the USA was called this way, which was brought to Holland as a clone together with other great genetics thanks to the breeder Nevil. Now you have it available in different seed banks, all quite similar, although for quality/price ratio we stick to those of PEV Bank.

The Paki caused a sensation in the late 70’s and early 80’s and, as everything good comes back, it became trendy again a little more than a decade ago. It is one of the most colorful indica landraces in the world, since it acquires very striking purple shades, which are transferred even in the extractions. The Old Paki Kush is part of the polyhybrid ancestors of Gorilla Glue, OG Kush, Sour Diesel or Cookies among others, as it is one of the parents of the great Chemdog.
