my favorite sativa but bc of the taste. Cinderella 99, Willy Wonder, Willy Wonka, Cinderella Dream, Casey Jones are all equally potent in my opinion, but PExpress has them beat on taste. I've tried strains from CO and Seattle. where the CO buds were small and tight and bright green (popcorn buds), the Seattle strain is big fat red haired dark and light green monster nug. it is what a sativa should be. it's an intense quick hitting heady high (no couch potato) that is uplifting and euphoric. taste ranges from fruity, pineapple of course, earthy, with hints of pine or wood. helps motivate. gives you a serious appetite. introspective and creative. my.fav.sativa. you will not be disappointed.
