seeing as the term "pineapple express", AFAIK, was never used in conjunction to describe weed until after the movie came out, i don't trust it. just like i have an inherent mistrust in g13 labs because their name comes from a movie....
i do recognize this could just be for fun but even if thats so, it means that the genetics for that strain haven't been around very long and cant be all that stable. Thats kind of how i feel about the strain Mr. niceguy. Ive been sold it once and it blew my mind, but still, its named after a movie and hasn't been around long(granted half baked is kind of old i guess).
They might be good strains that they just jokingly gave names from stoner movies, but i personally would never do it as it leads to myths and urban legends regarding a situation s such that the movie was about that weed, even tho the weed is actually about the movie....
blah tldr pointless.
