All Gas OG is the strain that used to circulate around Humboldt under the name Asphalt Plant, and the old nickname still fits. Everything about it runs oversized: broad fan leaves, a wide and heavy frame, fat colas, and a high that lands with real weight. This Indica-dominant feminized photoperiod with an average of around 21% THC is built for growers who want volume and smokers who want the day to end on the couch.
Humboldt Seed Company bred All Gas OG from two of its own OG workhorses, Humboldt Venom OG and Humboldt OG, then backcrossed the line to Bx5 so the traits hold from seed to seed. Expect dense, bright green buds stacked tightly along the branches and a moderate-to-heavy harvest that the breeder files under huge producer.
In a 55-day bloom the plant goes from leafy bush to a garden of hard, sticky nugs, and the room starts to smell like a skunk wandered through a pine forest carrying a bag of oranges. If gas-forward OG genetics with serious yield are on the shopping list, these seeds belong near the top of it.
Lineage and Breeding: Venom OG Meets Humboldt OG
The cross pairs Humboldt Venom OG with Humboldt OG, two lines that carry the classic Northern California OG backbone: resin-coated calyxes, pungent fuel, and a sturdy, productive frame. Rather than releasing a loose F1, Humboldt Seed Company ran the selection through five backcross generations. A Bx5 line like this tends to show less phenotype scatter, which matters when you are filling a tent or a field and want the plants to finish together.
The Asphalt Plant nickname came from growers who noticed how the strain dominated the garden and how hard the smoke hit. The name changed, the genetics did not.
Aroma, Flavor and Effect
Break a cured bud open and skunk comes first, loud and slightly sour. Under it sits a resinous pine note and a squeeze of orange peel that brightens the whole profile. On the exhale the gas comes through, the heavy fuel character that gave the strain its current name. Picture striking a match at a roadside gas station surrounded by pine trees while someone peels an orange next to you.
The effect is anything but subtle. Humboldt Seed Company calls it intensely relaxing, and the description is accurate: the first wave settles behind the eyes, then rolls down through the shoulders until the body feels like it is sinking into a deep leather armchair. Plans get canceled. This is an evening strain for experienced consumers who respect a high-octane OG and have nowhere to be.
Growing All Gas OG Indoors and Outdoors
Indoors, give All Gas OG more room than you think it needs. The plant spreads wide and builds a dense canopy, so topping once or twice in veg and opening the interior with light defoliation keeps airflow moving around those compact buds. A SCROG net helps spread the branches evenly. Bloom runs about 55 days, or roughly eight weeks, which is quick for a plant with this much mass.
Outdoors in a Mediterranean-style climate the strain turns into a monster. Plant it in large containers or native soil, stake or trellis the main branches early, and expect harvest between September 25 and October 10. That window lets most northern growers finish before the heaviest fall rains.

FAQ
Is All Gas OG Indica or Sativa?
All Gas OG is Indica dominant. Its Humboldt Venom OG and Humboldt OG parents give it a wide, heavy frame and a deeply relaxing, body-centered effect.
Is All Gas OG the same as Asphalt Plant?
Yes. Humboldt Seed Company originally released this line as Asphalt Plant and later renamed it All Gas OG. The genetics are the same Venom OG x Humboldt OG cross, now stabilized to Bx5.
How strong is All Gas OG?
Humboldt Seed Company lists an average of about 21% THC, with plants testing above 20%. Combined with its heavy OG character, it is a potent strain suited to experienced consumers.
How long does All Gas OG take to flower?
Indoors, flowering takes about 55 days, roughly eight weeks. Outdoors, the breeder places harvest between September 25 and October 10.
What does All Gas OG smell and taste like?
Expect loud skunk up front, resinous pine and orange peel in the middle, and a heavy gas note on the exhale. The aroma is pungent, so plan on good carbon filtration indoors.
How much does All Gas OG yield?
Humboldt Seed Company describes it as a huge, moderate-to-heavy producer. The breeder does not publish numbers, but large plants grown outdoors in full sun can fill a lot of jars.
