HP13 S1
Also known as: Hash Plant 13 S1, Hashplant 13 S1
HP13 S1 Strain Overview
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.

HP13 S1 Strain Growing Information
HP13 S1 is well-suited for both indoor and outdoor cultivation with a flowering time of 8-10 weeks (approximately 63 days). The strain demonstrates resilience and hardiness, making it suitable for novice to experienced growers. Indoor cultivation responds well to training techniques like low-stress training (LST) for optimized yields, while outdoor growers can take advantage of robust growth in favorable climates. Plants exhibit sturdy growth with dense bud development and require consistent temperature control (70-75°F), slightly acidic pH (6.0-6.5), and humidity levels of 50-60% during flowering to prevent mold. Regular pruning enhances airflow and reduces pest risks. The strain benefits from organic soil amendments and produces dense, resinous buds with superior quality.
