Yes what they are calling paki purple chitral is the PCK. Green Bodhi got it from bodhi who got it from cannabiogen. Blackbird preservations and a few others offer it now also. Ace and cannabiogen used the same stock originally. The paki purple chitral has been selected for the purple color but honestly the strain has been stabilized as a predominantly purple line for quite some time. I’ve grown the cannabiogen version in the past and am growing the beans from ace atm, there virtually identical so far.
