About Permanent Gas
Permanent Gas is a sativa-dominant hybrid created by crossing Permanent Marker (Seed Junky Genetics' 2023 Leafly Strain of the Year) with the legendary Sour Diesel. The strain perfectly balances old and new: Sour Diesel's electrifying, fuel-forward cerebral effects combine with Permanent Marker's deep musk, creamy sweetness, and signature 'permanent marker' chemical-candy aroma. The buds are dense and resin-rich with pale orange pistils and a healthy trichome coat. The aroma hits hard with piercing sour diesel fuel and grape bubblegum, transitioning into creamy sweetness, earthy pine, and a zesty spice on the finish. Effects begin with an instant cerebral lift and old-school sativa euphoria, followed by a gradual body relaxation that extends for hours without complete sedation. Permanent Gas typically tests between 25% and 28% THC with total cannabinoids exceeding 30%.
