Trainwreck was a strain that I did a lot of searching for, myself. Back in the 90's, in Northern California, I used to get some of the best weed that I never knew the name of. Well, come to find out, after smelling bag after bag, I finally discovered that what I had back in the 90's was trainwreck. I went to a lot of dispensaries trying to figure out what it was.
Anyhow, that's my story. There are E32 cuts of it, Arcata, too. Allegedly, it was grown in Oregon and Humboldt County back in the 70's and 80's. I'm going to pick up an Arcata clone this week, come to think of it. Nothing really compares to the sweet, sunny orange smell of a classic trainwreck. You'll know if forever once you smell it.
Since 2009 I've figured out the answer to this question. Billgoat made it popular in Northern Humboldt. He did not originally create trainwreck as far as I know, but he did breed the two most popular types of trainwreck (e32 and the arcata cut).Hard to say who did that first or even who made the first popular trainwreck. Somewhere up in Humboldt or Mendo I suppose.
