OG Kush Auto seeds are a hybrid autoflowering cross of OG Kush and ruderalis that delivers 17–24% THC in 8–10 weeks from seed to harvest, no light cycle switching required. You get the same citrus-diesel terpene profile and dense, resin-caked buds that made OG Kush a West Coast staple — just without the photoperiod fuss. Set your lights to 18/6 or 20/4 on day one and leave them there. The ruderalis genetics push the plant into flower automatically based on age, not light hours, so you skip the blackout curtains, the timers, and the anxious "did I light-leak?" checks at 3 AM.
Your pack size should match your grow space and experience level, not your ambition. OG Kush Auto seeds come in 1, 3, 5, and 10 seed options — here's how to pick.
| Pack Size | Best For | Typical Setup |
|---|---|---|
| 1 seed | Test run or single-plant windowsill grow | One pot, minimal gear |
| 3 seeds | Small tent or balcony grow, first-timers wanting a safety margin | 60x60 cm tent or 3 pots outdoors |
| 5 seeds | Standard indoor run with room for phenotype selection | 80x80 or 100x100 cm tent |
| 10 seeds | Dedicated growers running multiple cycles or filling a larger space | 120x120 cm tent or full outdoor plot |
Our honest take: the 3-pack is the best starting point for most growers. It gives you enough plants to compare phenotypes without committing to a full tent. If you already know you love OG Kush and want to run a proper canopy, the 10-pack saves you per seed and lets you pick the best performers.

Running OG Kush Auto indoors? Pair these seeds with a complete grow tent kit — tent, lighting, ventilation, and carbon filter in one box. A carbon filter isn't optional with this strain; the diesel terps announce themselves loudly once flowering kicks in around week 4. If you're growing in soil, grab a quality organic soil mix to keep things simple and let the genetics do the talking.
Standard photoperiod OG Kush is a brilliant strain that demands a lot from its grower. You're looking at 12+ weeks, precise 12/12 light switching to trigger flowering, blackout curtains if there's even a pinhole of light leak, and the constant paranoia that your timer glitched at 2 AM. For experienced growers running a dialled-in setup, that's fine. For everyone else, it's a lot of variables that can go sideways.
OG Kush Auto seeds strip out those variables. The ruderalis genetics mean the plant flowers based on age — not photoperiod — so you set your lights once and forget about them. That 8–10 week seed-to-harvest window means you can run 4–5 cycles per year indoors, compared to 2–3 with a photoperiod version. And the yield ceiling of up to 400 g/m² indoors is genuinely impressive for an autoflower. We've seen growers hit 350 g/m² on their first run with nothing more than decent light, consistent watering, and a quality soil mix.
The one honest limitation: autoflowers don't respond well to heavy training techniques like mainlining or aggressive topping. You can do light LST (low-stress training) to open up the canopy, but there's no vegetative extension period to recover from stress. If you top too late, you lose yield instead of gaining it. Stick to gentle bending and leaf tucking, and you'll get the best results from these genetics. Compared to something like Northern Lights Auto — which is more forgiving of beginner mistakes but caps out at lower THC — OG Kush Auto rewards a slightly more attentive grower with noticeably stronger, more flavourful buds.
These seeds don't need a complicated setup, but a few things done right from the start make a real difference to your final harvest.
The terpene profile on OG Kush Auto is unmistakable — and it's one of the main reasons this strain has stayed relevant for decades. Crack open a cured jar and you get hit with sharp citrus peel first, like someone zested a lemon directly into diesel fuel. Underneath that is a layer of earthy pine, almost like walking through a forest after rain, but with a chemical edge that's distinctly OG Kush.
On the inhale, the diesel comes through strongest. On the exhale, the citrus sweetens and the pine rounds things out. It's not subtle — your carbon filter earns its keep with this strain. Interestingly, research published in Frontiers in Psychiatry found that inhalation of a vaporised terpene blend from the OG Kush cannabis strain increased prosocial behaviour in animal models, suggesting the terpene combination itself may have notable effects beyond just flavour (PMC10311644, 2023).
The effect is a balanced combination of physical relaxation and mental alertness. You feel the body settle first — shoulders drop, jaw unclenches — and then a clear-headed talkativeness comes in. It's not a couch-lock strain at the lower end of the THC range (17–18%), though at 22–24% it can tip towards heavier relaxation, especially with more amber trichomes at harvest.
We've been shipping cannabis seeds from Amsterdam since 1999, and OG Kush in some form has been in the catalogue for most of that time. The autoflowering version outsells the photoperiod version roughly 3 to 1 these days, and the reason is simple: most home growers don't have a dedicated flower room with light-sealed timers. They've got a tent in the spare bedroom and they want results without a degree in horticulture.
The most common mistake we see? Overfeeding. OG Kush Auto doesn't need heavy nutrient schedules. New growers see the "up to 400 g/m²" figure and assume they need to push the plant hard with nutrients to get there. In reality, the yield ceiling is mostly about light quality, pot size, and not stressing the plant. A well-lit 80x80 tent with four OG Kush Autos in 15-litre pots, fed at moderate levels, will outperform a single overfed plant in a 7-litre pot every time.
One thing worth knowing: new users report sufficient effects at 5–10 mg of inhaled THC, while experienced consumers may take 15–30 mg per session. With OG Kush Auto testing at 17–24% THC, a single 0.3g joint could deliver anywhere from 51–72 mg of THC before combustion losses. Start with 1–3 inhalations if you're new to this strain and wait 15 minutes before deciding you need more. Effects typically last 2–3 hours.
It's a hybrid with indica-dominant structure — compact, bushy plants with dense buds — but the effects lean balanced. You get physical relaxation from the indica side and mental clarity from the sativa genetics. The ruderalis component doesn't noticeably affect the indica/sativa balance; it just handles the autoflowering trigger.
Up to 400 g/m² under good light in an 18/6 or 20/4 schedule. Realistically, first-time growers average 250–350 g/m². Yield depends mostly on light intensity, pot size (11–15 litres recommended), and not overfeeding. Four plants in an 80x80 cm tent is the sweet spot.
No. Set your lights to 18/6 or 20/4 on day one and leave them there for the entire grow. The ruderalis genetics trigger flowering automatically based on the plant's age, not light hours. That's the whole point of autoflowering seeds — no photoperiod management needed.
Yes, and it does well on a sunny balcony or in a garden that gets 6+ hours of direct sunlight. The compact size (typically 60–100 cm) makes it discreet. Outdoor yields are generally lower than indoor — expect 50–150g per plant depending on sun exposure and climate. The 8–10 week cycle means you can run two outdoor crops in a single summer in southern Europe.
Speed and simplicity. Photoperiod OG Kush needs 12+ weeks and a strict 12/12 light flip to flower. OG Kush Auto finishes in 8–10 weeks total with no light change. The trade-off is that autos can't be kept in vegetative state indefinitely, so you can't clone them or extend veg for a bigger plant. THC range and terpene profile are comparable.
The dense, heavily resinous bud structure makes it a solid choice for extraction. The trichome coverage is generous, and the citrus-diesel terpene profile carries through well into concentrates. Harvest when trichomes are mostly milky for the best terpene preservation in rosin or dry sift.
You can, but proceed with caution. Topping must happen early — before the 3rd node, ideally in week 2–3 — because autoflowers have a fixed vegetative period and no time to recover from late stress. Light LST (bending and tying) is safer and more forgiving. If you're not confident with your timing, skip the topping and stick to LST only.
Cannabis may increase side effects such as dizziness and drowsiness when combined with melatonin or gabapentin. If you use any sedating medication or supplement, be aware that the relaxing effects of a 17–24% THC strain can compound with those substances. Start low and pay attention to how you feel.
