OG Kush

OG Kush Feminized Cannabis Seeds by Royal Queen Seeds

OG Kush is a feminized cannabis seed strain from Royal Queen Seeds that delivers a heavy, Indica-dominant stone backed by legendary West Coast genetics. Born from a cross of Chemdawg, Lemon Thai, and Pakistani Kush — three cultivars that read like a hall of fame — this seed produces compact plants that stay under 1 metre tall and finish flowering in roughly 8 weeks. With THC levels that can push past 20%, it's built for growers who want potency without babysitting a towering plant. Royal Queen Seeds took the original Californian cut and refined it with Dutch breeding expertise, and the result is a seed that performs reliably indoors with yields of 50–70g per plant.

Why OG Kush Seeds Deserve a Spot in Your Grow Room

OG Kush earns its reputation through genetics, not hype. The Chemdawg backbone gives it that unmistakable fuel-forward, almost chemical bite on the nose — the kind of smell that hits you the moment you open the jar. Lemon Thai adds a citrus brightness that lifts the aroma, while Pakistani Kush anchors the whole thing with earthy, spicy depth. When you crack a dried bud between your fingers, you get that sticky, resinous coating that tells you the trichome production has done its job. The smoke is dense and layered: pine and lemon on the inhale, a diesel funk on the exhale that lingers in the room.

From a growing perspective, the compact size is the real selling point. At under 1 metre, these plants fit comfortably in an 80x80 or 100x100 tent without needing aggressive training. The 8-week flowering period is quick enough to run multiple cycles per year, and yields of 50–70g per plant are respectable for something this short. The honest limitation: 50–70g per plant isn't going to win any yield competitions. If you're chasing weight above all else, something like Royal Queen Seeds' Critical or a dedicated Big Bud cross will outproduce OG Kush. But what you lose in volume, you gain in potency and flavour. It's a trade-off we'd make every time.

The 75/25 Indica-to-Sativa split means the effect profile leans heavily toward a physical stone with a slight cerebral lift from that Sativa quarter. According to a study published in Frontiers in Pharmacology, OG Kush terpene profiles have been examined in the context of anxiety-related research, though results varied by concentration (PMC10311644). And according to research published in Complementary Therapies in Clinical Practice, a case study documented a patient's use of OG Kush-derived cannabis oil in a medical context (PMC7086060). We mention this for context — these are seeds, not medicine, but it's worth knowing the strain has shown up in clinical literature.

How to Grow OG Kush Feminized Seeds

1. Germination: Soak seeds in a glass of room-temperature water for 12–24 hours until they sink, then transfer to damp paper towels in a warm, dark spot (20–25°C). Taproots typically emerge within 24–72 hours.
2. Seedling stage: Plant the germinated seed taproot-down in a small pot with light, airy soil or coco coir. Keep humidity around 65–70% and light intensity low — a propagator helps here. Water sparingly; seedlings drown easily.
3. Vegetative growth: Once the plant has 3–4 sets of true leaves, move it under 18/6 lighting. OG Kush stays compact, so you won't need heavy topping, but a light LST (low-stress training) to open up the canopy will improve light penetration and airflow. Feed with a balanced grow nutrient at half strength initially.
4. Flip to flower: Switch to a 12/12 light cycle when plants reach roughly 30–40cm. They'll stretch a bit during the first two weeks of flower but shouldn't exceed 1 metre. Increase phosphorus and potassium in your feed, reduce nitrogen.
5. Flowering and harvest: Expect dense, resinous buds to develop over approximately 8 weeks. Watch the trichomes with a jeweller's loupe — harvest when most are milky with a few turning amber for that heavier stone. The fuel-and-pine smell will be intense during the final weeks, so make sure your carbon filter is running properly.
6. Drying and curing: Hang whole branches in a dark room at 18–20°C with 55–60% humidity for 7–10 days. Trim and jar when stems snap rather than bend. Cure in sealed glass jars for at least 2 weeks, burping daily for the first week. Patience here is what separates good bud from great bud.

OG Kush Compared to Similar Strains

OG Kush sits between White Widow and Northern Lights in terms of growing difficulty. Northern Lights is the most forgiving — it practically grows itself and finishes fastest. White Widow gives you a more balanced Indica/Sativa effect but takes an extra week. OG Kush is the one to pick if flavour complexity and raw potency are your priorities. That Chemdawg lineage gives it a terpene profile that neither of the other two can match.
