Katsu – OG #18 S1 [FEM]

OG #18, also known as “Private Reserve” OG, is one of the most respected and decorated phenotypes to emerge from the legendary OG Kush lineage. Its story is one of legacy, selection, and the relentless pursuit of perfection by some of the most influential breeders in the modern cannabis scene.

The story of OG #18 begins with DNA Genetics, the iconic seed company founded by Don and Aaron in Amsterdam in the early 2000s. They were among the first to bring elite Californian genetics to Europe, and their work helped elevate West Coast cannabis strains on a global scale.

Among the standout cuts they worked with was a particularly unique expression of OG Kush. After running an extensive pheno hunt through a pool of OG Kush seeds, they identified a special plant—phenotype #18—that stood out for its stronger yield, more pungent fuel-forward aroma, and heavier resin production compared to other OGs.

This plant didn’t just meet expectations—it redefined them.

The “#18” simply refers to the pheno number in the original hunt. It wasn’t some calculated marketing name—it was #18 in the lineup of OG seedlings, and it crushed the rest. Sometimes the best names are born out of raw selection, and the name stuck. Over time, “OG #18” became a mark of connoisseur status and breeder precision. It told the world: this isn’t just any OG Kush cut.

OG #18 wasn’t just a cult favorite—it became a champion. It has won numerous High Times Cannabis Cups, including:

• 1st Place Indica Cup, HTCC Amsterdam 2009
• 2nd Place Indica Cup, HTCC Amsterdam 2007
• 1st Place Europe Champions Cup 2010

Its consistency, potency, and rich flavor profile made it a standout not just in competitions but in grow rooms and dispensaries worldwide. Its diesel-fuel-meets-kush terp profile, thick structure, and knockout potency made it a go-to for both extract artists and flower purists.

In online forums and grow diaries, OG #18 consistently earns high marks for:

• Rock-solid structure (a bit more squat and Indica-leaning than traditional OGs)
• Insane resin production (often noted as “hashy” or “greasy” buds)
• Deep couchlock body effect with euphoric uplift (ideal for evening use)

While OG Kush clones have been traded and renamed endlessly in the U.S., OG #18 remained a staple of DNA Genetics’ feminized lineup, maintaining its reputation among elite OGs. In Europe, it served as many smokers’ first real taste of OG Kush. In the U.S., especially during the early 2010s, it earned legendary status among homegrowers looking for a true-to-form OG that didn’t stretch like crazy or yield tiny buds.

Over time, OG #18 has become a building block in many modern hybrid lines. Its heavy resin output and indica-heavy structure make it a breeding favorite, and its role in cannabis history is firmly cemented.
