CSI Humboldt Description

Genetics and Background

Humboldt Uppercut is a top-tier hybrid created through a collaboration between CSI and UnderRated. This cultivar brings together UnderRated’s U29 selection of CSI’s GSC x T-1000 with the iconic Purple Punch, resulting in a powerful and well-balanced genetic combination. By merging elite modern U.S. breeding lines, Humboldt Uppercut delivers consistency, vigor, and standout quality in every run. The carefully curated lineage ensures strong structure, impressive resin production, and a terpene profile that reflects the best traits of its parents.

Bud Structure and Visual Appeal

This strain forms dense, compact flowers with excellent weight and bag appeal. The buds showcase deep green tones accented by rich purple hues, while vivid orange pistils twist through the tightly stacked calyxes. A thick blanket of shimmering trichomes covers the surface, giving the flowers a frosted, almost crystalline finish. The heavy resin production not only enhances visual impact but also highlights the premium nature of this hybrid.

Aroma and Flavor

Humboldt Uppercut offers a layered terpene profile that combines sweetness, fruit, and earthy depth. On the palate, dessert-like cookie notes lead the way, complemented by ripe berry and grape nuances inherited from Purple Punch. Subtle earthy undertones add balance, creating a smooth and full-bodied flavor experience. The aroma mirrors the taste—sweet, fruity, and slightly pungent—filling the room with a rich blend of berries, doughy sweetness, and classic cookie funk.
