Can you explain these BX nametags to me? I dont understand this one. I saw Gelato BX or something the other day and was confused
From this page:
It is not rare to see novice growers wondering what IBL, BX or S1 mean. While they may seem useless, these acronyms give plenty of information when we know their meaning. In this post we tell you some basic concepts of cannabis genetics so you can fine-tune your choice when purchasing seeds.

BX or Backcross
Backcrossing is a common technique used by breeders to fix certain traits. This is done by crossing one of the progeny (F1, F2…) with one of the original parents (recurrent parent) which has the desired trait. To have an even more stable expression of the desirable trait, you can cross the BX1 again with the recurrent parent to have a BX2 (squaring) and so on with BX3 (cubing), BX4, BX5…
Backcrossing
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.

S1, feminised cannabis seeds
The acronym S1 refers to the first filial generation produced as a result of
crossing the plant with itself. This is achieved by a range of techniques aimed at reversing the sex of the selected female plant, getting it to produce male pollen and using it to pollinate itself. If it’s done properly, we get
feminised offspring with the same genotype of the parent used.
As always in genetics, the more stable the parent is, the more stable the offspring will be. This technique can also be used as a regular backcross, selecting and fixing traits but starting with just one parent. Thus, we can find S2 or S3 seeds, which have been backcrossed again with the original parent. Examples of S1 are
Tropimango (Philosopher Seeds),
S.A.D. (Sweet Seeds) or
Trainweck (Greenhouse).
