All Gas OG Auto, the strain once sold as Asphalt Plant, is built on size. Big plant, big leaves, big nugs, and a heavy, intensely relaxing high that lands like a snakebite. Humboldt Seed Company rates it a huge producer, and the autoflower version keeps that trait while finishing in 80-100 days from seed.
The buds come in dense and bright green, loaded with the skunky gas that made the photoperiod version popular. THC averages 21%, which is plenty for an evening strain designed to slow everything down.
For autoflower growers who usually trade yield for speed, All Gas OG Auto is a strong argument that a fast plant can still fill the jar.
All Gas OG Auto Genetics and Breeding
The auto parentals are All Gas OG x Asphalt OG x Chunkadelic Auto. The photoperiod All Gas OG and Asphalt OG lines supply the fuel terpenes and the oversized structure, while Chunkadelic Auto, another Humboldt Seed Company auto, carries in the automatic flowering trait and its chunky bud formation.
The breeder lists the current seed lots as Bx5, meaning the line has been backcrossed five times toward the target type. That work shows in the consistency of the gas profile and in the indica growth pattern from plant to plant.
Aroma, Flavor, and Effect
Crack a nug and the first thing out is skunk, thick and sharp. Pine follows with a resinous green edge, and a streak of orange peel lifts the back end of the aroma. The smoke carries the classic gas profile on the palate, with the citrus showing up mostly on the exhale.
The effect is described by the breeder as intensely relaxing. It settles quickly into the body, loosens the shoulders, and quiets the mind without much of a cerebral run-up. This is a late-day strain: put on a movie, keep snacks nearby, and do not plan anything complicated afterward.
Growing All Gas OG Auto Indoors and Outdoors
Autoflowers need no light switch, so run 18/6 or 20/4 for the full cycle and expect harvest 80-100 days after germination. All Gas OG Auto is one of the larger autos in the Humboldt Seed Company catalog, so give it a roomy final container from day one and leave enough vertical space for a sizeable plant.
Low-stress training during the first three to four weeks opens the canopy and helps the dense colas get light all the way down. Outdoors, plant after the last frost in full sun; the generous cycle length rewards rich, well-aerated soil. Because the buds pack tight, keep humidity in check during late flower and thin inner fan leaves if airflow is poor.
