HP13 S1

HP13 S1 is a indica cannabis strain with up to 22.0% THC, known for its relaxed effects and earthy and hash flavor profile.

HP13 S1 is a predominantly indica strain developed by CSI Humboldt through self-pollination (S1) of the legendary HP13 (Hash Plant 13) clone. This strain represents a direct descendant of the original heirloom HP13 clone that gained fame in New York City cannabis circles during the 1990s. The original HP13 lineage traces back to Afghan landrace genetics brought to America during the hippie hashish trail era of the 1970s, making HP13 S1 a preservation of this historic genetic line.

The strain displays classic indica characteristics with dense, compact buds featuring deep green hues accented by purple highlights and bright orange pistils. The flowers are heavily coated in glistening trichomes, giving them a frosty crystalline appearance that signals high resin production. HP13 S1 is known for its complex flavor profile combining earthy, hash-like tastes with layers of pine, spice, black pepper, and fresh herbs. The aroma is equally distinctive, blending sharp pine, deep spice, and subtle herbal undertones.

CSI Humboldt's meticulous breeding approach has ensured genetic stability and consistent cannabinoid levels across grows, making HP13 S1 popular among both novice and experienced cultivators. The strain maintains the authenticity of the original HP13 genetics while offering the convenience of feminized seeds, eliminating the need to identify and remove male plants during cultivation.
