The problem with that whole thing is Kenny Powers aka "pieguy420" is a liar, a thief, and an in general shit talker. He claims to have "created" girl scout cookies and cherry pie with his "secret" selections. Word of mouth says that he stole it and what he thought were the parents from another grower that was holding out on the parents and mix. Something like what happened to Adam Dunn with bubblegum. I'm just repeating what I have heard and my general first impression of "pieguy420". Supposedly there is no cherry pie in GSC, but they share the F1 Durban dad.
Supposedly Cherry Pie = Grandaddy Purp x F1 Durban (that is Durban x F1) F1 being an unknown) then supposedly the Girl Scout Cookies are = Triangle Kush x F1 Durban
Fire Alien Kush is from OG Raskal (fire OG x (Las Vegas Purple Kush x (Chem D x Alien Technologies)))
