Permanent Marker (SeedJunky) strain review — aroma, flavour and effect.
Mr.GramGram · 12 June 2026 · 6 min read
Permanent Marker is one of the most talked-about SeedJunky releases of recent years. I ran a full cycle with it from original seed, so what follows is my own growing and tasting experience rather than a retelling of other people’s reviews.
Origin, and why the version matters.
Permanent Marker first appeared in June 2022 as packaged flower, a collaboration between SeedJunky and Doja Pak. Seeds only became available in 2023 and only as S1 (feminised). That detail matters: a “Permanent Marker from another company” is almost certainly a fake or an S2. Genetically it is a triple hybrid — Biscotti × Jealousy with a triple backcross to Sunset Sherbet.
The plant and the grow.
Before flowering the strain gives away nothing exotic — unlike Fruit Gum or Agent Orange, whose fruity aroma is already noticeable in veg. But by mid-flower the exclusivity of the aroma builds rapidly. A distinctive trait: flowers and leaves are dark, and below +25 °C they begin to blacken.
Aroma, flavour and effect.
The aroma is complex and reads more as dessert-and-pastry than fruity, with a clear gassy note; the resemblance to an actual marker pen is there but distant. The flavour is hard to break down into a single tone. In terms of effect it belongs to the potent category — close to our own 50 Dragons, but less sedating.
Questions and answers.
What is the genetic background of Permanent Marker?
A triple hybrid: Biscotti × Jealousy with a triple backcross to Sunset Sherbet.
Why do Permanent Marker leaves turn black?
It is a trait of the strain: below +25 °C the dark pigment expresses more strongly. In a warmer regime the colouring stays lighter.
What does Permanent Marker smell like?
A complex dessert-and-pastry aroma with a clear gassy note; the resemblance to a marker pen is distant.
