About this strain
This new strain from Humboldt Seed Company sets the bar high for unique terpene profiles. The product of a vast 2017 phenotype hunt in Humboldt County, Pineapple Upside Down Cake smells exactly like its name. The effect is immediately rewarding, uplifting, and spiritual. The Trainwreck sativa brings a sharp loudness and the indica balances its energetic effect. Said to lift spirits, Pineapple Upside Down Cake really takes the cake when it comes to new and exciting strains.
