Be patient, especially when your question is unclear.
What do you mean by selfed? They cloned an og? Caused an og to herm and then crossed the female pollen with the original female? Just crossed a og male with an og female?
Say I buy 50 OG seeds. Even if it is a stable strain each of the 50 plants will be slightly different. Say I pick out my two favorite and cross them - the end result will again all be different from each other but more similar to the two parents than the other 48 original plants. Now say I do this a bunch more...they are all still OG but they are slightly different than the original 50 seeds I purchased. To differentiate this a number is placed after the "og" name.
You can name anything btw. Guess what Larry Og is...It's just OG. Happened that one certain plant was a bit better so someone named it - genetically its just one more OG, its brothers and sisters were og, og, og, og, but that one plant happened to get a name. Crazy how caught up people get on names.
