Auto Blueberry Ghost OG is an autoflowering cannabis seed from Original Sensible Seeds that races from germination to harvest in 70–75 days while keeping its parent's fruity berry punch intact. Bred by fusing a select Auto OG Kush with the original photoperiod Blueberry Ghost OG, this hybrid packs 18% THC into a compact plant that won't eat your whole grow space. Good for first-time growers who want genuine OG flavour without the faff of flipping light cycles.
Why Auto Blueberry Ghost OG earns a spot in the tent
Original Sensible's photoperiod Blueberry Ghost OG has been their flagship for years — frosty, fruity, genuinely potent. The problem: not everyone wants to mess with 12/12 light schedules, light leaks, or a 9-week flowering stretch. This auto version solves that. You plant the seed, give it 18–20 hours of light from day one to harvest, and 70–75 days later you're cutting buds. No pre-veg planning, no flip, no second-guessing.
The Blueberry Ghost OG lineage brings OG Kush structure crossed with a blueberry-leaning phenotype — think dense, resinous nugs with that unmistakable berry-on-earth profile. The Auto OG Kush infusion keeps the terpene expression largely intact while handing over the autoflowering genetics. You lose a bit of size versus the photoperiod mother, but you gain speed and simplicity.
She stays short and bushy, which is honest gold if you're growing in a 60x60 tent, a cupboard, or outdoors where a towering plant draws the wrong kind of attention. Natural resistance to mould and common pests is decent — not bulletproof, but forgiving enough that a first-time grower with a half-decent setup should pull a harvest.
Seed pack variant guide
Azarius stocks this strain in a single pack size:
- 3 seeds (SKU CSOS0044) — the standard Original Sensible pack. Good for a first run in a small tent, or to test the phenotype before committing a full cycle. With autos you don't get to clone a keeper, so each seed is one shot at harvest.

How Auto Blueberry Ghost OG stacks up against alternatives
Direct answer: if you want OG Kush flavour in an autoflower, this is the shorter, faster option versus the photoperiod parent — at the cost of some yield and peak THC.
| Strain | Type | Time to harvest | THC | Best for |
|---|---|---|---|---|
| Auto Blueberry Ghost OG | Auto | 70–75 days | 18% | Fast, stealthy, beginner-friendly OG |
| Blueberry Ghost OG (photoperiod) | Fem photo | 9 weeks flower + veg | Up to 22% | Max potency and yield, experienced growers |
| Standard Auto OG Kush | Auto | ~70 days | ~16–18% | Classic OG nose without the berry |
How to grow Auto Blueberry Ghost OG
- Germinate between damp paper towels or in a glass of lukewarm water for 24–48 hours until the taproot shows.
- Transfer directly to the final pot — autos hate transplant shock. 11–15L airpots work well for the compact size.
- Run 18–20 hours of light per day from day one. No light flip needed.
- Feed light during the first 2–3 weeks. Autos are smaller eaters than photos — overfeeding is the number one rookie mistake.
- Low-stress training (LST) is fine from week 2–3; avoid heavy topping, she doesn't have time to recover.
- Flowering kicks in automatically around week 4–5. Switch to bloom nutrients.
- Watch trichomes from week 9. Harvest when most are cloudy with a sprinkle of amber — 70–75 days from germination.
- Dry slowly at 18–20°C and 55–60% humidity for 10–14 days, then cure in jars for at least 2 weeks to let the blueberry terps really come forward.
Flavour and effect — what to expect from the finished product
Light up cured Auto Blueberry Ghost OG and you get a berry-forward inhale with a sour edge, grounded by that earthy OG Kush base on the exhale. It's not a one-note blueberry candy profile — there's depth, some pine, a hint of kush funk underneath. Proper cure makes a noticeable difference; rushed jars taste flat.
The 18% THC sits in "respectable but not overwhelming" territory. A couple of hits and you're into an uplifting, clear-headed onset that shifts after 30–45 minutes into a heavier body relaxation. It's balanced enough to smoke during the day without being glued to the sofa, but relaxing enough in the tail that it works for an evening as well. Honest limitation: if you're chasing 25%+ THC trophy weed, this isn't it. If you're chasing a plant that actually tastes of something, it is.
Pairs well with an 80x80 grow tent and a basic LED setup — autos don't need a massive footprint, and the Mars Hydro or Lumatek panels we stock will finish her comfortably. Grab a pH meter and some quality autoflower-specific nutrients to keep feeding dialled in.
Frequently Asked Questions
Is Auto Blueberry Ghost OG suitable for first-time growers?
Yes. The autoflower genetics remove the light-cycle juggling that trips up beginners, and the plant has decent natural resistance to common mould and pest issues. As long as you don't overfeed and you respect the 70–75 day timeline, it's one of the more forgiving hybrids on the shelf.
Can I grow Auto Blueberry Ghost OG indoors or outdoors?
Both. Indoors she yields up to 450 g/m² under good light. Outdoors she hits up to 150g per plant and stays compact enough for stealth or balcony grows. Autos let you squeeze 2–3 outdoor cycles into a single European summer.
How much THC does Auto Blueberry Ghost OG contain?
18% THC according to Original Sensible Seeds. That's lower than the photoperiod parent (which can hit 22%), but still firmly in the potent category. Expect a balanced uplift-then-relax effect rather than a flattening couchlock.
Why choose the auto version over the photoperiod Blueberry Ghost OG?
Speed and simplicity. Seed to harvest in 70–75 days versus veg plus 9 weeks flowering on the photo. No light-cycle flip, smaller plant, easier to hide. You trade some yield and peak THC for a faster, lower-hassle grow.
What does Auto Blueberry Ghost OG taste like?
Berry-forward with sour and earthy undertones — the blueberry is present but not candy-sweet, grounded by the OG Kush backbone. A proper 2-week cure in jars brings the terpenes forward significantly. Rushed weed tastes flat.
How many seeds come in a pack?
3 feminised autoflowering seeds per pack (SKU CSOS0044). Since autos can't be cloned productively, each seed is one full grow cycle.
