The OG #18 made the keeper list, then started collecting hardware. DNA Genetics’ Reserva Privada label selected plant #18 from its feminized OG Kush seeds and re-feminized it into a standalone line. The breeder prized its sharper sour flavor and improved yield. Same OG roots, extra bite.
Its awards include third place for indica at the 2007 High Times Cannabis Cup, second in the same category in 2009, and first for hydro at Spannabis in 2011. The OG #18 also contributed its genetics to Holy Grail Kush, keeping the trophy cabinet in the family.
Sour fuel dominates the aroma, with lemony Kush and earthy musk underneath. The flavor carries diesel and tart citrus into a hashy finish. DNA compares its fuel-heavy character to Chemdog, while the dense, hard flowers come coated in crystals. Private Reserve keeps very little of that smell private.
Smokers put relaxation, tingles, and sleepiness high on the list of OG #18 effects, often alongside a contented, euphoric head change. Some find room for music or quiet concentration; others report settling in for the night. Reserved seating sounds about right.
The OG #18 seeds are offered as feminized photoperiod seeds, with DNA listing the genetics as OG Kush S1. Indoor flowering takes approximately nine weeks, and the breeder lists yields of 500–600 grams per square meter.
DNA describes the selection as producing at least a third more than its original OG Kush offering. Seed-grown plants can still vary, so those figures are targets rather than guaranteed harvests.
Dense flowers and substantial resin production make airflow and humidity management worth close attention during bloom. Allow room for individual plants to develop, support branches as needed, and plan odor control around that persistent sour-fuel aroma. This reserve announces itself.
