Basic infos

R-KIEM Seeds Description

G.O.S. S1 (feminized) by R-Kiem Seeds is a photoperiod strain created through self-pollination of a carefully selected elite clone from the original G.O.S Regular (Ghost OG x Purple Punch 2.0). With approximately 70% indica dominance and THC levels ranging from 25% to 30%, it combines premium genetics with exceptional stability, achieved through the precise fixation of the S1 process.

Elite genetics refined with precision

The foundational cross, Ghost OG x Purple Punch 2.0, unites two highly regarded lineages. Ghost OG contributes classic Kush traits such as a compact structure, heavy resin production, and a deep, physical effect. Purple Punch 2.0—derived from Larry OG and Grandaddy Purple, both strongly indica-leaning varieties—adds a sweet, fruity aromatic layer that defines the strain’s sensory identity. Through S1 stabilization of an elite clone, this profile is reproduced with high consistency, resulting in a uniform and reliable feminized line with stable expression.

Indoor and outdoor cultivation: strong structure and generous yields

Indoors, G.O.S. S1 completes flowering in around 9 weeks (approximately 63 days), producing yields in the range of 550–650 g/m² under optimal conditions. Plants grow with a compact, well-branched structure and short internodal spacing, forming dense, weighty buds. The favorable calyx-to-leaf ratio simplifies post-harvest work, while the abundant trichome coverage makes it especially well suited for high-quality resin extraction. Overall difficulty is moderate, making it suitable for both experienced growers and those looking for a dependable feminized strain without excessive complexity.

Outdoors, harvest typically takes place in mid-October. Its sturdy structure supports heavy buds effectively, requiring only minimal staking and allowing for relatively straightforward cultivation in outdoor environments.

Aromas, flavors, and effects

The aroma and flavor profile is led by tart blueberry and sweet grape notes, layered with hints of ripe fruit candy. Beneath this fruity sweetness lies a strong earthy Kush backbone inherited from Ghost OG, rounded out by subtle menthol accents that add freshness and depth. The result is a balanced, multi-layered profile combining Purple Punch sweetness with OG-driven earthiness.

The effects align closely with its indica-dominant genetics: a powerful, long-lasting experience that begins with a strong cerebral onset before transitioning into deep physical relaxation. Best suited for evening use and downtime, it is not intended for active or highly demanding moments, but rather for rest and unwinding at the end of the day.
