Lol how can you tell what strain a bud is by just looking at it? You cant...just know that it's either trainwreck or it's not. If it gets you fuckin' blew then what the hell are you worrying for? The only time I'd be suspicious about a strains name is if some one is using that to try to boost the price, other than that what ever...as long as I get high in the zone I'm cool.
