All the trainwreck I have tried has been pretty consistent over the last 25 years that I have smoked it... I guess it's where you live...
I definitely would not trust a Greenhouse version of anything.... as said before they try to imitate version... There are plenty of strains that made it to Amsterdam in clone form (Indiana Bubblegum for example) but Greenhouse sure didn't get any.
Best pheno I tried was called Wayne's Trek on the Train wreck..
I went to Humboldt state for a year (circa 1987) and I'm sure that I wasn't even smoking the best stuff available cause I was just a college punk... But Trainwreck and Golfball Skunk were the weed du jour so I became intimate with those flavors.. Ironic that the golfball skunk became extinct and the trainwreck is at the bottom of the list with regard to my favorite strains..
@SurfD I would be happy to sample your stock to let you know if it's the real deal
@PunaBud I have found so many strains out here that people claim are one thing.. and they turn out to be something completely different... For example all the God's Gift that I have been encountering the last year around North Shore was not Og x Mendo Purps (or OG x GDP) like I have encountered in California.. Also the AK47 and White Widow out here are nothing like I remember from my early adventures with ganja..
I really think a lot of dealers/Growers out here will throw names on stuff they get just to get more interest... Most people are clueless.....
I know most of the folks on this board know what they are growing because lots of you are going out and getting the seeds from the original breeders...
