Iron Horse is a Greenpoint Seeds hybrid with Kush in its pedigree and enough chemical funk to announce its arrival. Crossing Kosher Kush with Stardawg, it brings an OG-related California cut together with the pungent Chem family. The name has horsepower, and the nose supplies the fumes.
Sour lemon, fuel, and a sharp cleaning-solution note lead the aroma, with fresh soil, pine, skunk, and rubber adding depth. Some expressions bring softer vanilla and soapy notes underneath that bite. The flavor settles into earthy Kush, pine, and fuel, while sticky, resin-heavy flowers give the cross plenty of visual appeal. This is pungency with a citrus edge.
Heads in the know clock a fast, hard-hitting high that pairs euphoria with a restful finish. Smokers describe feeling lifted mentally while the body settles into a more comfortable, relaxed state. That combination gives Iron Horse some initial momentum, but the physical side can pull the session toward taking it easy. An upbeat headspace doesn’t make this one a lightweight.
Greenpoint released Iron Horse as regular photoperiod seeds, producing both male and female plants. Flowering takes approximately 60–70 days. It is suited to indoor and outdoor cultivation, with temperate conditions listed for outdoor gardens.
Plants finish medium to tall and can produce substantial, heavily resinous flowers. Yield potential is described as high, without a verified numerical estimate. Greenpoint’s original specifications rate the cultivar as advanced, despite some growers finding it straightforward to cultivate and clone.
