PREROLLS - HYBRID - 10x0.5G Blueberry Yum Yum comes from the classic old-school cultivar BC Blueberry OG. This deeply purple hued flower is densely caked with trichomes and smells like a freshly harvested blueberry. Adding Cake to the mix creates a unique blend of smooth creamy smoke, synonymous to Cake strain, and sweet characteristics known to the Blueberry lineage.
