Hi @sirtween,
Thanks for your comment, I confused that it was claimed by Serious crew but the actual comment was from a senior member in another forum. Hope this can be a good information to you.
However, around 2010 some growers said that they found Cherry pheno or similar thing from Nirvana’s Ak48. Some people assume that Ak48 is old Ak47 F2 or F3.
One Love
