The uk cheese which is only available in clone form is what everyone wants.
Quite some time back in the uk there was a group of people that grew out some skunk#1 there was one pheno that was totally different and had a totally unique taste and high.
It was cloned heavily and was passed around as a free clone, anyone that wanted it should have been able to get a cutting.
Big buddha got a cutting and back crossed it 5 times with an afghani which diluted the strain from what it was, its still good but its not the same as uk cheese.
Blue cheese is a cross between the back cross and blueberry.
Greenhouse seeds have just released a feminized version although it is from a cut of the back cross and not the uk cheese.
