"True Blueberry" is the sixth or seventh filial generation of "Blueberry" according to the seedfinder.
If I were to break Dj shorts genetics down, I would divide it between his Purple Thai Afghani and his Highland Thai Afghani. His (Purple Thai Afghani is Oaxacan Gold x Chocolate Thai x Afghani) and commonly referred to as the "Floral line" and then there is this (Highland Thai x Afghani) Male that come around once in a while and has it's way with the women of the floral line.
If the F2 of the "Floral Line" is "Floral Line" then the F3 is Temple Flo and the F4 is where the "Blue Berry Sativa" is located and commercially "F-13" is the F5 of the Purple-Thai-Afghani and "Flo" is also a commercially available F6 of the floral Line.
F2=Floral Line
F3=Temple Flo
F4=BlueBerry Sativa
F5=F13
F6=Flo
Blueberry is the result of the F1 Highland Thai Afghani male f**king and the F3 Temple Flo (Purple Thai Afghani).
True Blueberry is the result of those babies having babies and those babies having babies for 4-5 more generations....
F1= Blueberry Line
F2= Blueberry
F3=(What you get from Dutch Passion?)
F4= not available commercially
