Green Poison Auto by Sweet Seeds
Man, if you've been messing around with autos over the last decade, you've probably crossed paths with Green Poison Auto from the Spanish crew at Sweet Seeds. This 3rd-generation auto is built off a cross between their Big Devil #2 and an elite cut of the original Green Poison. But they didn't just smash them together and call it a day. The breeders backcrossed the hybrid twice to the original Green Poison mother to lock down that signature sweet stink and heavy resin production. It's one of those rare autos that genuinely captures the soul of its photoperiod parent without losing its speed.
In the dirt, this thing is an absolute workhorse. You're looking at a stupid-fast 8-week turnaround from seed to harvest, which makes it perfect for running quick cycles. Most of the time, you'll see a squat, indica-dominant structure that just piles on thick, sticky colas. But if you pop enough beans, you'll occasionally find a more vigorous, branchy phenotype that wants to stretch out and show off that old-school Green Poison vigor. It's notoriously easy to grow, taking heavy feeding without throwing a fit, and if you dial in your environment, pulling 500 grams per square meter indoors is completely doable.
When it comes to the smoke, Green Poison Auto doesn't mess around. The jar appeal is ridiculous, reeking of intensely sweet, overripe fruit backed up by a dirty skunk funk and hints of old cheese. And yeah, it hits just as heavy as it smells. This is not your morning wake-and-bake material. It delivers a fast-acting, physically crushing stone that'll glue you to the couch and eventually put you to sleep. It's exactly the kind of heavy-duty nighttime meds that real growers look for, proving why this genetic line remains an absolute staple in the autoflower scene.

Growing Green Poison Auto: what to expect
Because Green Poison Auto is an autoflower it runs on age, not photoperiod: keep it under 18–20 hours of light from sprout to harvest, start in its final pot, and go easy on training after week 3 — autos never pause to recover. Growers familiar with Green Poison or Green Poison will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
