West Coast O.G. Auto

West Coast O.G. Auto Feminised Cannabis Seeds

West Coast O.G. Auto is a feminised autoflowering cannabis seed from FastBuds that packs genuine OG Kush genetics into a compact, fast-finishing plant. Built from selected West Coast lineages — the same Californian and Oregonian gene pool responsible for some of the most sought-after Indica flower on the planet — this auto stays under 100cm, finishes in 8–9 weeks from seed, and delivers up to 500–650g/m² indoors. If you want heavy Kush resin production without a separate veg and flower light schedule, this is the seed to drop.

Why West Coast O.G. Auto Seeds Deserve a Spot in Your Grow Room

OG Kush has a reputation that borders on mythical — and sure, some of it is hype. But the core of it holds up: properly grown and cured OG Kush produces a narcotic, deep-body Indica effect that genuine Kush lovers rate above almost everything else. FastBuds took selected West Coast OG Kush mother plants and crossed them with proven autoflowering genetics to create a strain that genuinely competes with photoperiod Kush varieties on potency and flavour, while shaving weeks off the total grow cycle.

The result is a plant that tops out around 100cm, produces homogeneous and compact phenotypes, and coats its buds in millions of trichomes during the final week of flowering. Those trichomes start white and fluffy, then turn amber — giving the finished buds an almost sandy, crystalline appearance that tells you the resin glands are packed. At 21% THC, this isn't a mild smoke. The effect leans heavily Indica: deep physical relaxation, couch-lock territory, with earthy pine flavours on the exhale.

One honest note: autoflowers are never quite as forgiving on yield as photoperiods if you make mistakes early. A stunted auto can't recover the same way a photoperiod plant can — you can't just extend veg time. So get your environment dialled in from day one. That said, West Coast O.G. Auto is a genuinely easy-going plant. FastBuds designed it to handle a reasonable range of conditions, and it responds well to both novice and experienced growers. We'd call it one of the best autoflowering Kush seeds for growers who want maximum resin with minimum fuss.

Growing West Coast O.G. Auto: Yield, Height, and What to Expect

West Coast O.G. Auto stays compact — 100cm maximum — which makes it a strong fit for tents where headroom is limited. In an 80x80cm or 100x100cm tent under a decent LED, you can comfortably fit 4–9 plants and aim for that 500–650g/m² ceiling. The plants grow with a classic Kush structure: tight internodes, thick stems, and dense lateral branching that fills out nicely without much training.

Outdoor growers can expect 70–300g per individual plant, depending on technique, climate, and container size. That's a wide range, and it's worth understanding why: an auto in a 7-litre pot on a balcony in northern Europe is a very different animal to one in a 30-litre fabric pot in southern Spain with 14 hours of direct sun. The genetics can deliver — you just need to give them room.

For indoor growers chasing maximum yield, low-stress training (LST) works well with this strain. Gently bend the main stem during the first 2–3 weeks to open up the canopy and expose lower bud sites to light. SCROG nets also work, though with an 8–9 week total lifecycle you need to get the net in place early. Avoid topping unless you're experienced with autos — the recovery window is tight, and a stressed auto won't bounce back the way a photoperiod will.

Flavour, Aroma, and the Final Week of Flowering

The terpene profile on West Coast O.G. Auto is textbook OG Kush: earthy, with a dominant pine tree note that comes through on both the inhale and exhale. There's a subtle herbal sweetness underneath — not fruity, not candy, just a clean, resinous Kush flavour that coats the palate. If you've ever cracked open a jar of well-cured OG and caught that sharp pine-and-earth hit, you know exactly what to expect here.

The final week of flowering is where this strain really shows off. The buds develop a thick, fluffy white coating of trichomes that gradually shifts to amber. It's one of those visual cues that tells you the plant is finishing properly — and it's genuinely impressive to watch. The resin production at 21% THC is heavy enough that trimming becomes a sticky affair. Keep a pair of scissors and some isopropyl alcohol handy.

One thing we've noticed with Kush autos in general: they benefit enormously from a proper dry and cure. Rush the drying process and you'll lose a lot of that pine complexity. Aim for 10–14 days drying at around 60% humidity and 18–20°C, then cure in glass jars for at least 2 weeks. The difference is night and day.

How to Grow West Coast O.G. Auto Seeds

1. Germinate seeds using the paper towel method or directly in a small pot of moist, light soil mix. Taproots typically emerge within 24–72 hours.
2. Plant the germinated seed 1–1.5cm deep in its final container — transplanting autos is risky because any root stress costs you growing time you can't get back. We'd go straight into an 11–15 litre fabric pot for indoor grows.
3. Provide 18–20 hours of light per day from seedling stage through harvest. Autoflowers don't need a light cycle change, which is one of their biggest advantages. A good full-spectrum LED at around 200–400W actual draw covers a 100x100cm canopy nicely.
4. Keep humidity at 65–70% during the seedling phase, dropping to 50–55% during flowering. Temperature should sit between 20–26°C. West Coast O.G. Auto is a sturdy plant, but it performs best when conditions are consistent.
5. Start with light feeding — autos are sensitive to overfeeding in the first two weeks. Increase nutrient concentration gradually as the plant enters pre-flower around week 3. A standard cannabis-specific nutrient line at 50–75% of the recommended photoperiod dose works well for most autos.
6. Apply low-stress training (LST) from week 2–3 if you want to maximise yield. Bend the main stem gently and secure it with plant ties. Avoid high-stress techniques like topping unless you have auto-specific experience.
7. Watch for the trichome colour shift in the final week. When most trichomes have turned milky white with some amber, it's harvest time. This typically falls at the 8–9 week mark from seed.
8. Dry slowly in a dark, ventilated space at 18–20°C and 60% humidity for 10–14 days. Cure in sealed glass jars, burping daily for the first week, then every few days for at least 2 more weeks.

West Coast O.G. Auto vs Other FastBuds Autoflowering Strains

FastBuds has a solid lineup of autoflowering genetics, so it's worth knowing where West Coast O.G. Auto sits. Compared to something like Gorilla Glue Auto (also from FastBuds), West Coast O.G. leans more heavily into that classic Kush structure and flavour — earthy pine rather than diesel and chocolate. The Gorilla Glue may edge it on raw THC percentage in some phenotypes, but West Coast O.G. delivers a more traditional, narcotic Indica effect that Kush purists prefer.

Against photoperiod OG Kush seeds, the trade-off is straightforward: you sacrifice some potential yield ceiling and the ability to control veg time, but you gain a dramatically shorter total cycle and the simplicity of not managing light schedules. For growers running multiple cycles per year, or those with limited space, the auto version makes practical sense without giving up much on flavour or potency.
