Breeders do not agree on where this one came from. The Seedsman line crosses Purple Alaskan with Kush and a Brazilian sativa; others trace it to Northern Lights and Afghani. Every version lands in the same place, so the disagreement matters less than it sounds.
Is Alaskan Purple indica or sativa?
Indica-leaning, whichever lineage you believe.
Purple colouring is common in this one, but colour comes from how the grower finished the plant as much as from genetics, so do not buy on the photo alone.
