OG Kush

OG Kush by Humboldt Seeds — the legendary West Coast strain, feminized

OG Kush by Humboldt Seeds is a feminized cannabis seed of the fabled California cultivar that built the reputation of modern West Coast genetics. This is the one veteran growers keep coming back to — piney, lemony, heavy-hitting, and with a backstory mysterious enough to keep cannabis nerds arguing at dinner parties for years. Humboldt Seeds' version is a clean, stable expression of that classic OG profile, packaged in feminized form so every seed you pop gives you a bud-producing plant.

Why OG Kush earned its spot in the cannabis hall of fame

OG Kush is the cultivar that basically defined the 1990s California cannabis scene and spawned half the menu at every dispensary since. Whether the "OG" stands for Original Gangster or Ocean Grown is still debated at grow-forum level — most old-school Californians go with Ocean Grown, a nod to its coastal roots. What's not debated: the genetics are rumoured to be a three-way between ChemDawg, Lemon Thai and Pakistani Kush, and the result has been copied, crossed and renamed more times than we can count.

Humboldt Seeds, based in the heart of Northern California's Emerald Triangle, know this plant better than almost anyone. Their feminized OG Kush keeps the classic terpene profile — sharp pine, fresh lemon, a bit of earthy fuel in the background — and the dense, frosty bud structure that made the original famous. It's the kind of strain that gets recognisable fingerprints: once you've smelled proper OG, you don't mistake it for anything else.

A quick honest note: OG Kush is not the easiest plant in the world to grow. She likes her nutrients dialled in, prefers warm and dry, and won't forgive you if you overwater. If this is your first ever grow, a Critical or a Northern Light is a gentler starting point. Come back to OG once you've got one cycle under your belt — she rewards experience.

OG Kush specifications and grow profile

Here's what you're working with. Humboldt's OG Kush is a mostly-indica hybrid that stays medium-sized indoors and can stretch a bit more outside if the climate plays along.

Flavour and aroma — why people chase this strain

OG Kush's terpene fingerprint is the whole reason this cultivar became legendary. Myrcene brings the earthy, slightly musky backbone and limonene delivers that sharp lemon-pine top note you can smell the moment you open the jar. There's usually a hint of fuel or diesel underneath — classic OG funk that separates the real deal from the copycats.

On the smoke or vape, expect a thick, coating mouthfeel with pine resin up front, citrus pith in the middle, and a slightly peppery finish. It lingers. If you've been running fruit-forward strains for a while, OG Kush is a proper reset — it tastes like cannabis the way people used to describe it before every terp became "grape-gas-candy-zkittle."

Effects and what to expect

OG Kush is potent. This isn't a beginner's evening cultivar — it's a heavy-handed indica-leaning hybrid that hits in the head first and settles into the body. Research on cannabis chemotypes and their effects suggests that myrcene-dominant varieties tend to produce more sedative, physically relaxing profiles, while limonene contributes mood-lifting characteristics (Russo, Taming THC, 2011, PMC3165946).

According to WebMD's overview of cannabis strains, research suggests cannabis has been used by some people to manage chronic non-cancer pain and reduce reliance on over-the-counter pain medication. According to a 2020 review on cannabinoids and terpenes (Tomko et al., PMC7409346), clinical data have been compiled on cannabis-based treatments across a variety of conditions — though none of this is a guarantee of individual experience, and OG Kush in particular is known for being strong enough to catch experienced smokers off guard.

Common observed side effects with high-THC cultivars include dry mouth, dry eyes, and occasional dizziness or increased anxiety at higher doses. Start low, wait, and see how you respond — especially with a strain this potent.

How to grow OG Kush from Humboldt Seeds

1. Germinate your seeds in damp kitchen paper or a germination cube at 22–25 °C. Expect tap roots within 24–72 hours.
2. Transplant into a light, airy soil or coco mix. Avoid heavy feeding in the first two weeks — OG Kush is sensitive to nutrient burn early on.
3. Veg for 3–5 weeks under an 18/6 light schedule. Top once or twice to encourage lateral growth — she responds well to LST and ScrOG.
4. Flip to 12/12 when plants are around 30–40 cm tall. Expect a stretch of roughly 50–80% during the first three weeks of flower.
5. Feed moderate P and K through flower, keep humidity at 40–50% to avoid bud rot on the dense colas, and watch for powdery mildew — OG can be susceptible.
6. Flush during the last 10–14 days. Harvest at 8–9 weeks when trichomes are mostly cloudy with a few amber.
7. Dry slowly at 18–20 °C and 55–60% humidity for 10–14 days, then cure in jars for at least 3 weeks. The terpene profile sharpens noticeably after a proper cure.

Honest limitations — what OG Kush isn't

OG Kush is not a stealth grow. The smell in flower is loud, and without a carbon filter running 24/7 in late flower, your whole building will know. She's also not the highest yielder on the shelf — if kilograms are your main goal, a Critical or a big Sativa will outperform her. And she can be picky about humidity: dense buds + humid tent = rot risk.

What you're buying OG Kush for is flavour, potency, and pedigree. If those are your priorities, nothing else quite scratches the same itch.
