Posion Kush by Pure Michigan Genetics
Long before the modern hype market took over, Pure Michigan Genetics was quietly dropping serious heat in the Midwest, and their Posion Kush (often spelled Poison Kush) was an absolute foundational staple. As a cross between a classic Durban Poison mother and an OG Burmese male, this sativa-dominant hybrid was a workhorse for old-school growers who frequented ICMag and early THCFarmer boards. Released strictly as regular seeds back in the day, it was the kind of plant you popped when you wanted a heavy yield without sacrificing that loud, old-world terpene profile.
Cultivating Posion Kush requires a bit of space and some serious canopy management. Thanks to that Durban influence, she exhibits wild sativa vigor and will stretch hard if you don't stay on top of your training. But if you give her the root space and dial in the environment, she stacks massive, spear-like colas that absolutely reek of sweet anise, sharp pine, and a greasy Kush earthiness. Growers always praised how well she handled stress and how easily she rooted clones, making her an ideal mother plant to keep in the veg tent for years.
What makes this strain truly legendary, though, is its legacy as breeding stock. Pure Michigan Genetics used Posion Kush to create a massive chunk of their catalog. Whether it was the infamous Death By Kush, Cyanide Kush, or the legendary 517 Headband, the Posion Kush male passed on that unmistakable yield and complex flavor to everything it touched. It’s a piece of Midwestern cannabis history that reminds us of a time when breeders were focused on stability, loud terps, and plants that actually thrived in the garden instead of just looking pretty in a photograph.

Growing Posion Kush: what to expect
As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with 517 Durban Poison or Burmese Kush 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.
