The Mulanje Gold landrace traits are doing a great job of dominating all of the recessive genes.
However, I can tell you which ones are TGA crosses by the smell. Cherry Diesel!
The Plushberry crosses smell like froot loops. Sweet lemon-lime berry.
The Mulanje crosses have the Old Spice/Basil herbal incense smell.
The Scott's OG crosses all have a coffee/cocoa skunk smell.
The Blue Dream crosses all have the blueberry smell.
The LA Cons are hard to describe. They can be piney, cheesey, skunky, coffee...
I frankly can't remember what the Quantum Kush smelled like.
The Paki Punch was old school incense hash smell.
