OG Kush

OG Kush Auto Cannabis Seeds by Barney's Farm

OG Kush Auto is an autoflowering cannabis seed from Barney's Farm that crosses the legendary OG Kush with BF Super Auto #1 to deliver a fast, compact, and seriously rewarding grow. From germination to harvest in just 10 weeks, this strain produces dense, resinous buds with a complex earthy-citrus-skunk flavour profile and a THC content of 20–24%. If you want OG Kush genetics without the photoperiod fuss, this is the seed to grab.

Why OG Kush Auto Seeds Deserve a Spot in Your Grow

Barney's Farm bred OG Kush Auto specifically to make the OG Kush experience accessible without a complicated light schedule. The autoflowering genetics from BF Super Auto #1 mean this plant doesn't care about your light cycle — she'll flower on her own clock, roughly 10 weeks from the moment the seed cracks open. That's a full harvest cycle shorter than most photoperiod OG Kush cuts.

What you get at the end is worth the (minimal) effort. The buds carry that unmistakable OG Kush nose: a dense, earthy base layered with sour citrus and a lingering skunk finish. Crack a bud open and you'll notice the stickiness immediately — trichome coverage on a well-grown OG Kush Auto is genuinely impressive for an autoflower. The smoke leans towards a cerebral, upbeat effect at 20–24% THC. A couple of draws and you'll feel the mood shift — energising, clear-headed, the kind of effect that works just as well at a gathering as it does on a quiet afternoon.

The honest limitation? She tops out at around 120cm. That's actually a benefit if you're working with a tent or a small room — but if you're after towering outdoor plants that produce kilos, this isn't the strain for that job. What she lacks in height, she compensates for in density and speed.

How to Grow OG Kush Auto Seeds

One of the best autoflowering strains for first-time growers. Here's the rundown:

1. Germinate your seeds using the paper towel method or directly in a small pot of moist, lightly fertilised soil. Taproots typically appear within 24–72 hours.
2. Transplant seedlings into their final container early — autoflowers don't love being moved once they're established. An 11–15 litre pot works well for indoor grows. Fabric pots give better root aeration if you have the option.
3. Set your indoor lights to 18/6 or 20/4 for the entire lifecycle. OG Kush Auto doesn't need a light switch to trigger flowering — she'll do it herself around week 3–4.
4. Keep feeding light during the vegetative stretch. Autoflowers are sensitive to overfeeding, so start at half the recommended dose of your nutrients and increase gradually. She responds well to a balanced NPK ratio early on, shifting to higher phosphorus and potassium once flowers form.
5. Watch the height. At 120cm max, she's manageable, but if your tent is on the shorter side, a bit of low-stress training (LST) in weeks 2–3 will open up the canopy and boost light penetration to lower bud sites.
6. Harvest around week 10 from germination. Check trichomes with a jeweller's loupe — you're looking for mostly milky with a few amber heads for that cerebral, upbeat effect OG Kush Auto is known for.
7. Dry in a dark, ventilated space at around 18–20°C and 55–60% humidity for 7–10 days. Cure in glass jars for at least 2 weeks. The earthy-citrus-skunk flavour really comes alive after a proper cure.

What OG Kush Auto Smells and Tastes Like

This is where OG Kush Auto earns its name. The terpene profile is complex — a thick, earthy base that hits you first, followed by a sharp citrus tang and sour notes that linger on the palate. Underneath it all sits that classic skunk funk that OG Kush has been famous for since the '90s. It's not a one-dimensional flavour; each draw reveals a different layer. In a vaporiser at around 185–195°C, the citrus notes come forward more than in combustion, which tends to emphasise the earthy and skunky side.

The smell during the grow is noticeable from about week 5 onwards. Not overwhelming compared to some photoperiod OG cuts, but enough that indoor growers absolutely need a carbon filter. We've had customers tell us they could smell it through a closed door by week 7 — and that was with ventilation running.

OG Kush Auto Compared to Other Autoflowers

Barney's Farm has a solid autoflower catalogue, and OG Kush Auto sits comfortably in the middle-to-upper tier. Compared to something like a Gorilla Zkittlez Auto, OG Kush Auto leans more cerebral and energising rather than heavy and sedating. The yield potential of up to 500g/m² indoors is competitive — many autoflowers in this price range top out around 350–400g/m².

Against a photoperiod OG Kush, you're trading some of the raw potency ceiling and plant size for speed and simplicity. A photoperiod OG can push past 25% THC with expert growing, but it'll take 16–20 weeks and requires precise light management. OG Kush Auto gets you 20–24% THC in 10 weeks with zero light schedule changes. For most home growers, that trade-off is a no-brainer.
