Sister Glue is an extremely potent strain. Its THC levels average from 26% to 28%, which place it at a level above most recreational buds in the market today. Apart from its potency, its main selling point is its combination of effects. Its onset starts with a light euphoric rush that intensifies into a relaxing buzz. From head to toe, it envelops users in a stress-crushing high that turns one’s day around from bad to good.

In creating the strain, its breeders took Chem’s Sister, Chocolate Diesel, and Sour Dubb in a three-way cross. The first two influenced its offspring’s potency and subtle cerebral stimulation. Meanwhile, the third herb contributed to its impressive trichome production, sweet terpene profile, and tranquilizing body buzz.
