Green Poison XL Auto is a third-generation Autoflowering strain selected over multiple generations from taller Green Poison Auto plants. The result reaches 80–125 cm (31.5–49.2 in), around 25% taller than its predecessor, with increased flower and resin production.
Sweet Seeds developed this XL version through recurrent selection of taller Green Poison Auto individuals.
Its 8-week cycle from germination keeps things moving fast. Indoor production can reach 450–600 g/m² (1.48–1.97 oz/ft²), while outdoor plants can produce 60–250 g (2.1–8.8 oz) each.
We really like this strain because it does not trade speed for personality. You get bold effects, an expressive aroma, and a memorable flavor from a taller automatic plant with serious production potential.
Effects
With 15–20% THC, the effect leans toward relaxation and happiness while also stimulating appetite.
The sensation can feel like your shoulders sinking into an old armchair while your mind quietly turns the lights down. The mood stays warm and easy rather than frantic.
We think Green Poison XL Auto makes particular sense for consumers who value a relaxed experience with a comfortable emotional tone and noticeable appetite stimulation.
Flavor
Green Poison XL Auto starts sweet and fruity, but it refuses to stay simple. A familiar Skunk background pushes through, followed by touches of arugula and walnut.
Its flavor moves like a fruit cart rolling through a smoky backstreet, then crashes into a sack of fresh walnuts. Sweetness comes first, while earthier and savory details linger afterward.
The fruity sweetness keeps things approachable, while Skunk, arugula, and walnut notes add depth. We think that contrast gives Green Poison XL Auto a more distinctive personality than automatic strains built around simple sweetness.
