One of the most popular strains on the market today is the Pineapple Express. While the Pineapple Express became immensely popular after the release of the movie by the same name, it’s been around for much longer than the movie. The exact origins are a bit hard to trace as there is no specific data on where it first appeared. It’s a Sativa-dominant strain from G13 Labs that was developed by crossing the Trainwreck and the Hawaiian weed. It is the right choice for connoisseurs who appreciate the strains with higher than average potency. THC content in this weed can reach 37%.
