Green Poison by Sweet Seeds
Sweet Seeds brought this one out of Spain back around 2009, and it's been an absolute staple in European gardens ever since. They kept the exact genetics closely guarded for a long time, just saying it came from elite clones in their private vault, but anyone who has run it can tell you it's a heavy Skunk and Early Skunk cross. It's built a whole family of fast-flowering and auto variants, but the original photoperiod is where the real magic happens.
If you're growing in a humid climate, you have to watch out. The plants get incredibly dense and bushy, packing tight internodes that can be a magnet for botrytis if your airflow isn't dialed in. But the tradeoff is worth it because this thing flowers ridiculously fast—sometimes finishing indoors in barely 7 weeks. Outdoors, you can chop it by mid-September, beating the worst of the autumn rains. You'll pull down some serious weight, often hitting 600 grams per square meter inside.
The nose on Green Poison is something else entirely. You get this intense, sweet fruitiness up front that slams into a heavy Skunk funk. But the real old-school heads will tell you about the savory undertones—there are distinct hints of walnut, arugula, and sharp spices hiding in the background. When you smoke it, the high kicks off with a creative, euphoric buzz right in the head, but don't let it fool you. Give it twenty minutes and it melts into a heavy, couch-locking body stone that's perfect for killing insomnia and muscle spasms.

Growing Green Poison: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Mostly Indica 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.
