Hybrid THC 33.0%

Permanent Marker

One of the most potent modern hybrids available, combining Biscotti, Jealousy, and Sherb BX genetics into an ultra-resinous, gas-forward powerhouse.

About Permanent Marker

Permanent Marker was bred by Seed Junky Genetics, crossing Biscotti with a cross of Jealousy and Sherb BX (a Sherbet backcross). It represents the cutting edge of potency-focused modern breeding, regularly testing at THC levels between 28% and 33% in lab results, making it among the most potent strains commercially available. It has rapidly become one of the most hyped releases of the 2020s and commands premium prices at dispensaries.

The appearance lives up to the reputation: the buds are extraordinarily frosty, with a trichome density so extreme that the underlying plant material is barely visible beneath the thick, white-amber resin matrix. The colour is predominantly deep purple to near-black in phenotypes that express maximum anthocyanin production. The aroma is pungent and aggressive — sharp, diesel-forward fuel notes dominate, backed by a sweet, creamy cookie base and an herbal earthiness. The name references the strength of the aroma, which, like a permanent marker, is difficult to ignore and hard to remove.

Effects are overwhelming at standard doses for most users. Even experienced consumers with high tolerances report that Permanent Marker delivers a swift, heavy-hitting experience that demands respect. The initial euphoria is intense and immediate; the physical stone that follows is total and long-lasting. It is not a functional strain at any meaningful dose — it is intended for evening or night use by those seeking maximum potency for pain, insomnia, anxiety, or simply an extraordinary experience.

Growing is challenging. The plants are demanding in their requirements, producing extreme resin output that needs careful management. Flowering runs nine to ten weeks.
