Green Poison Auto

Green Poison Auto Cannabis Seeds

Green Poison Auto is an indica-dominant autoflowering cannabis seed bred by crossing the original Green Poison with ruderalis genetics, delivering a fast-finishing plant with thick, resinous buds and a terpene profile that leans heavily into sweet, earthy, and fruity territory. At 70% indica and 30% sativa, this Spanish-bred hybrid wraps you in a mellow body effect with just enough creative headroom to keep things interesting. Flowering wraps up in about 8 weeks from seed — no light schedule fiddling, no photoperiod stress.

Why Green Poison Auto Deserves a Spot in Your Grow

The appeal of Green Poison Auto comes down to three things: speed, flavour, and forgiveness. Eight weeks from germination to harvest means you can fit multiple cycles into a single season, or just get from seed to jar before impatience sets in. We've stocked plenty of autoflowering strains over the years, and this one consistently delivers dense, frosty buds without demanding expert-level attention.

The yield ceiling of 500g/m² indoors is genuinely impressive for an auto. You won't hit that number under a desk lamp, obviously — proper lighting, good airflow, and a sensible feeding schedule get you there. Outdoors, expect up to 150g per plant, which is solid for a plant that rarely pushes past a metre tall. The compact size makes it a natural fit for balcony grows, small greenhouses, or discreet garden corners.

One honest limitation: because the ruderalis genetics lock in the autoflowering trait, you can't keep a mother plant or take clones in the traditional sense. Every run starts from seed. That's the trade-off for not having to manage light cycles — and for most growers, it's a trade worth making. If you want a photoperiod version with more control over veg time, look at the original Green Poison feminised seeds instead.

Flavour and Aroma Profile of Green Poison Auto

Green Poison Auto's terpene profile is dominated by myrcene at roughly 30%, backed by caryophyllene at 20% and pinene at 15%. In practice, that translates to a thick, sugary sweetness on the inhale — think overripe fruit with a candy-shop edge — followed by earthy, slightly spicy undertones and a pine finish that lingers. There's a faint diesel note buried in there too, and depending on the phenotype, some growers pick up a mild cheese funk during late flower.

The aroma during the grow is noticeable. By week 5 or 6, the terpenes are loud enough that a carbon filter isn't optional if you're growing indoors. The cured bud smells like a sweet fruit bowl left in a cedar box — dense, layered, and hard to mistake for anything else. If you've grown classic Skunk-lineage strains before, this carries that familiar pungency but with a sweeter, more complex finish.

How to Grow Green Poison Auto

1. Germinate your seeds using the paper towel method or directly in a small pot of moist, light soil. Keep the temperature between 22–26°C and the medium damp but not waterlogged. Taproots typically appear within 24–72 hours.
2. Transplant seedlings into their final container early — autos don't recover well from transplant shock, so moving them once (or starting in the final pot) saves stress. A 10–15 litre pot works well for most setups.
3. Provide 18–20 hours of light per day throughout the entire lifecycle. Autoflowers don't need a 12/12 flip, and the extra light hours translate directly into bigger yields. LED or HPS both work; just keep the canopy temperature under control.
4. Feed lightly during the first two weeks — around EC 0.5 with a CalMag supplement in the water is a solid baseline. Once you see the first pre-flowers, gradually increase nutrients, switching to a bloom formula when bud sites appear.
5. Watch for the stretch between weeks 3 and 5. Green Poison Auto can reach 60–100 cm, and some low-stress training (LST) during early veg opens up the canopy for better light penetration. Avoid topping — most autos respond better to gentle bending than having their main cola removed.
6. Flush with plain water for the final 7–10 days before harvest. Check trichomes with a loupe: milky white with 10–20% amber is the sweet spot for this strain's mellow, indica-leaning effect.
7. Dry in a dark, ventilated space at 18–22°C and 55–60% humidity for 7–10 days. Cure in glass jars for at least two weeks — the sweet terpene profile deepens noticeably with proper curing.

Green Poison Auto vs. Other Fast-Flowering Autos

Stacking Green Poison Auto against other popular autoflowering strains in the catalogue helps narrow down what suits your setup and taste.

Green Poison Auto sits in a sweet spot: faster than Northern Lights Auto, more flavour complexity than Critical Auto, and a yield that competes with both. If you want the heaviest possible body stone, Northern Lights wins. If you want to harvest as fast as physically possible, Critical Auto shaves off a week. But for the best balance of speed, taste, and potency, Green Poison Auto is the one we'd pick.
