An Award-Winning Classic
OG Kush is a genuine champion with a competition record to match its fame, taking Spannabis wins in both 2010 and 2011 and a Cannabis Cup win in 2014. Wins spread across several years and events speak to how consistent and high-quality the genetics really are, which is exactly what you want from a foundational strain.
For a grower, that track record is a useful signal: it points to stable genetics and a reliable finish. You can find it alongside our other award-winning cannabis seeds if you want more proven performers in the same mould.
Climate and Where to Grow It
OG Kush is well suited to a temperate climate with plenty of light and good airflow. It is a productive, adaptable plant that performs both outdoors in a mild season and in a controlled indoor tent, reaching a medium-tall 1.5 m with a noticeable sativa-driven stretch early in bloom, so plan for some height.
Outdoors it finishes around October, with a single plant bringing in a high 350–450 g in a good spot. Indoors it produces an impressive 450–600 g/m². Keep humidity in check as the dense, resinous buds fill in, since tight OG flowers in a warm, humid room are worth protecting from mould and bud rot in the final weeks.
Indoors, aim for daytime temperatures around 68–78°F (20–26°C) and keep steady airflow through the canopy. OG Kush is a little more demanding than some hardier indicas, so good environmental control and support for the stretchy branches go a long way toward a clean, heavy harvest.
Working with Regular Seeds
OG Kush comes here as regular seeds, which means each plant can grow into either a male or a female. That is different from feminized seeds, so part of the grow is identifying the sex early in flowering and removing the males if your goal is a harvest of smokable, seedless buds.
For most growers that means watching the pre-flowers closely once you flip the lights, then culling the males before they release pollen. For breeders, though, regular seeds are a real advantage: keeping healthy males lets you preserve and work with this foundational Lemon Thai, Pakistan and Chemdawg line, which is why regular OG Kush is so prized.
Flowering and Feeding
As a photoperiod plant, OG Kush flowers on a light change rather than on age. Grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 cycle to trigger flowering. Bloom runs about 8–10 weeks, filling in dense, resinous, diesel-scented buds through the second half.
OG Kush tends to prefer a leaner feed than many hungry hybrids, so keep nutrients moderate rather than heavy. Start low, build up as the plant asks for more, and taper off for a plain-water flush in the final week or two so the pungent diesel and lemon flavour comes through clean. The EC guide below is a solid starting point.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the dense buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Harvest, Drying and Curing
Harvest when most trichomes have turned milky-cloudy with a few amber heads, which gives the fullest expression of OG Kush’s balanced, uplifting character. Run a short plain-water flush in the last week or two before you cut, which keeps the smoke smooth and lets the diesel-lemon flavour shine at its best.
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks, which deepens the pungent aroma and smooths the smoke.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. OG Kush is a frosty, resin-rich plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of pungent, diesel-lemon concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
OG Kush has the classic profile that defined a category: pungent diesel and fuel with a bright lemon-citrus lift and a fruity edge. It is a sharp, unmistakable taste rather than a sweet or mild one, and it is a big part of why the strain became so iconic.
It carries a broad, complex terpene stack, and the ones that shape the flavour stand out clearly. Limonene and citral drive the bright lemon; caryophyllene and humulene bring the pungent diesel; and terpinolene with myrcene round it out with a fruity depth. A supporting cast of cedrene, pinene, terpineol, borneol, linalool and more fills in the aromatic corners.
Effects and Best Use
With its near-even genetics, OG Kush is reported as creative, energetic and uplifted, a bright, functional lift balanced by a relaxed body base. That mix is a big part of its lasting appeal, making it a versatile strain that works through the day and in social settings rather than only at night.
At a medium 15–20% THC it is potent but approachable, which suits both newer users and anyone who prefers a balanced, manageable high. That character, the high yield, the competition pedigree and the unmistakable diesel-lemon flavour are exactly why OG Kush remains one of the most sought-after strains in the world.
Common Problems and Pro Tips
The first thing to plan for with OG Kush Regular is the regular seeds themselves: because plants can be male or female, your main job early in bloom is to check pre-flowers and pull the males before any pollen is released, unless you are deliberately breeding. Isolating a chosen male well away from your flowering females keeps a seedless crop clean while still letting you work with this legendary line.
OG Kush also has a reputation for being a little fussier than the hardiest indicas. Its dense buds and sativa stretch make it more prone to powdery mildew and bud rot in humid rooms, and it dislikes heavy feeding, which can show up as nutrient burn on the leaf tips. Keep humidity moderate, run steady airflow, feed leaner than you would a hungry hybrid, and stake or net the stretchy branches so the heavy colas stay supported.
As a pro tip, lean into training: topping or a little low-stress training early tames the stretch and spreads the canopy, which both controls height and opens the plant up for better airflow and light. Watch the trichomes closely as finish approaches rather than relying on the calendar, and give it that clean plain-water flush in the final weeks so the famous diesel-lemon flavour comes through at its sharpest.
FAQ
Are OG Kush Regular seeds feminized?
No. OG Kush Regular comes as regular seeds, so each plant can grow male or female. For a harvest of seedless buds, identify the sex early in flowering and remove the males before they pollinate. If you plan to breed, those males let you preserve this foundational Lemon Thai, Pakistan and Chemdawg line.
What awards has OG Kush won?
OG Kush has a strong competition record, taking Spannabis wins in 2010 and 2011 and a Cannabis Cup win in 2014. That track record across several years points to stable, high-quality genetics that finish consistently, which is reassuring whether you are a first-time or experienced grower.
How long does OG Kush take to flower?
About 8–10 weeks once you switch to a 12/12 light cycle, with outdoor plants finishing around October. It is a photoperiod strain, so it blooms on the light change rather than on age, filling in dense, resinous, diesel-scented buds through the second half of flowering.
Is OG Kush indica or sativa?
OG Kush is indica-leaning, at roughly 60% indica and 40% sativa, which gives it a relaxed body base lifted by a bright, energetic head high. That near-even balance is a big part of its appeal, making it an uplifting, creative strain that stays functional rather than purely heavy.
What does OG Kush taste like?
Expect the classic OG profile of diesel and fuel with a bright lemon-citrus lift and a fruity edge. Limonene and citral drive the lemon, caryophyllene and humulene bring the pungent diesel, and terpinolene with myrcene round it out with a fruity depth, exactly as its legendary reputation promises.
How much does OG Kush Regular yield?
It is a high-yielding classic, giving around 450–600 g/m² indoors and 350–450 g per plant outdoors in a good spot. OG Kush packs dense, resinous buds onto a manageable frame, so keep the canopy open and support the heavier colas to get the most from its generous output.
