Permanent Marker × Sour Diesel — sativa-lean fuel cross on Leafly's 2026 list.
Permanent Gas crosses Permanent Marker — itself a Doja Pak 2024 standout — with Sour Diesel, building a sativa-leaning hybrid that lands on Leafly's 2026 hot-strain ranking. The sativa lean carries the diesel punch from the Sour D side over the candy-vapor finish from the Marker. Both parents already live in this corpus, which makes the family tree clean.

Aromatic chemistry
The Permanent Marker parent carries that pencil-and-marker volatile-organic note — pull it forward and the Sour Diesel side adds fuel on top. The combination is genuinely solvent-bright on the open of the jar.
Permanent Marker came from Doja Pak; Permanent Gas is the downstream cross. Specific breeder attribution for the Gas cross varies — multiple growers picked up the Marker pheno and crossed it locally, so several near-identical Gas crosses circulate.
Permanent Gas keeps Sour Diesel's head-up energy but adds the Marker's candy-vapor finish on the exhale. Smell is louder than straight Sour D; effect runs in the same energy lane.
Sativa-leaning, so daytime. Regulars who already reach for Sour Diesel and Jack Herer rotate Permanent Gas in when they want a 2026-vintage version of the same energy.
