Train Wreck Feminized Seeds

Train Wreck, also spelled Trainwreck, is a sativa-dominant feminized strain, 90% sativa and 10% indica, with a sweet lemon and spicy pine aroma. It is a three-way landrace cross of Mexican and Thai sativas with Afghani indica, and Leafly describes its effects as hitting like a freight train. Expect THC of up to about 19%. It is rated easy to grow and flowers in about 8 to 10 weeks.

History & lineage

Train Wreck is a Northern California strain with a hazy past. The usual story places it in Arcata, in Humboldt County, at some point during the 1970s: Leafly passes on a story that growers grew it among a train wreck in Arcata, and Humboldt Seed Organisation’s description also gives it an origin in Arcata. The name comes with a legend. As Cannigma tells it, a couple of brothers harvested their crops early because a train wreck had happened nearby and they didn’t want the emergency crew to stumble on their plants. One seed company’s history of the strain calls that story an unsubstantiated legend.

The genetics are less disputed. Leafly says Mexican and Thai sativas were bred with Afghani indicas to produce this Northern California staple, and the feminized line sold today is listed as a cross of Mexican, Thai and Afghan landraces.

Aroma & flavour

Expect citrus and pine up front, with herbal and mint undertones; Leafly describes a sweet lemon and spicy pine aroma. For Train Wreck as a strain, Leafly users most often report earthy, pine and pungent flavours, followed by lemon and citrus. Leafly’s lab data lists terpinolene as its most abundant terpene, followed by myrcene and pinene. Terpinolene is not a common lead terpene, and our guide to cannabis terpenes covers what it brings.

Effects, as users report them

These are Leafly users’ reports for Train Wreck as a strain, most common first, with energetic next; the feminized line’s own listing gives creative, euphoric and uplifting. Leafly describes effects that hit like a freight train, and the fast onset can catch inexperienced users off guard. Dry mouth and dry eyes are the downsides reported most, and smaller numbers of users report dizziness, paranoia or anxiety. Leafly’s strain data puts its THC at about 17%. Effects vary with the person and the dose, so if you are new to cannabis, start with a small amount.

Growing Train Wreck

Train Wreck is a feminized photoperiod plant: it stays in vegetative growth until the light drops to 12 hours a day indoors, or until the days shorten outdoors. Leafly’s grow notes say indoor gardens are ready after about 8 weeks, and the feminized line is listed at 9 to 10 weeks of flowering, so plan on 8 to 10. Outdoors in the Northern Hemisphere the harvest typically comes at the end of October, while Leafly notes that its flowers tend to finish early outdoors. Our seed-to-harvest timeline shows how that fits a full grow.

Leafly rates it easy to grow, with a high yield. It is a moderately tall plant, reaching roughly 100–150 cm (3.3–4.9 ft) indoors and up to about 200 cm (6.6 ft) outdoors, so leave room for the stretch. It responds well to topping (see topping vs fimming), and Leafly lists it as a medium to heavy feeder. Expect indoor yields around 550–600 g/m² (about 1.8–2.0 oz/ft²) and 600–700 g (about 21–25 oz) per plant outdoors. It suits climates with long summers. Near the end, use the trichomes to judge when to harvest.
