OG Kush is a household name, and its origins are as debated as its flavor is beloved. Some say it descends from Chemdawg, Lemon Thai and Pakistani Kush. Others say it began as a special Chemdawg cutting from the early 90s. Even the initials are argued over, though most people now agree that OG stands for Ocean Grown, a nod to its California coastal roots.
Royal Queen Seeds settled the question for its own version by working from that classic trio: Chemdawg, Lemon Thai and Pakistani Kush. The result is a stable feminized photoperiod with a 60% indica / 40% sativa split, high potency and a mouthwatering terpene profile. This O.G. Kush also earned 1st place at the Highlife Cannabis Cup.
In the grow room she stretches a little at the start of bloom, then fills out fast. Indoors she reaches 3 to 5 feet (90–150 cm) and yields 15 to 17 oz/m² (425–480 g/m²) after 50–60 days (about 7–8.5 weeks) of flowering. The buds are large, dense and lime green, covered in a thick layer of resin.
Outdoors she can tower at 6 to 7 feet (185–215 cm) and produce 18 to 19 oz/plant (510–540 g/plant). The data sheet points to short-summer climates, with harvest arriving in October.
The Unmistakable OG Flavor and High
Crack a jar of O.G. Kush and you will understand why people chase this aroma. The nose leads with sweet citrus and bright fruit, backed by fresh pine and a subtle fuel edge that hints at the Chemdawg in her bloodline. Royal Queen Seeds names myrcene, limonene and caryophyllene as the dominant terpenes behind that recognizable scent.
With THC up to 19%, the effect is strong and complex. Despite her indica-leaning genetics, the high opens with an uplifting, almost sativa-like mental lift, then spreads through the body for a calming, full-body feel. Mind and body get equal attention, and that balance is why so many experienced smokers rank OG Kush among their favorites.
It is like a sunset drive along the Pacific Coast Highway with the windows down: bright, breezy and unhurried, with a mellow glow that grows as the light fades.
Training O.G. Kush for Bigger Harvests
O.G. Kush responds very well to basic training. Topping early in veg pushes her to grow several main stems and more bud sites. Mainlining and low-stress training both help tame her bushy, dense canopy and keep it well aerated, which matters once those fat colas start stacking up. Give her a good carbon filter as well, because that citrus-fuel aroma travels.
