I grew GG4 from fastbuds as a test to see if auto's are any better now than they used to be, they have gotten somewhat better but honestly fastbuds GG4 is not GG4 at all, i have a clone of GG4 and been growing in for quite some time, they aren't remotely close in any area , smells , flavors, bud structure, high , all completely different. Fastbuds is just cashing in on hype of other strains names i highly doubt GG4 was used in this cross and if it was their ruderalis male has stomped all over it.
