there's no being familiar with a certain strain anymore, every seed bank has a strain from a different breeder, and not a single fucking one of them are the same as another...i have 3 different versions of gorilla glue 4, one from the vault, one from Pev, and one from seedsman(where they have 3 strains called gorilla glue that look nothing alike at all)....and they look, smell, grow nothing alike....
