Skywalker Auto Cannabis Seeds by Greenhouse Seeds
Skywalker Auto is an autoflowering cannabis seed from Greenhouse Seeds that crosses Skywalker OG with Gelato #41 Auto — two heavyweight USA genetics packed into a compact, 9-week seed-to-harvest plant. With 25% THC potential and a 50% indica genetic profile, she delivers dense, purple-tinged buds dripping with earthy-woody terpenes. If you want elite genetics without the fuss of photoperiod growing, this is the seed to drop.
Choose Your Pack Size
Skywalker Auto seeds come in three pack sizes — pick the one that suits your grow plan:
| Pack | Seeds | Best For |
|---|---|---|
| 3 seeds | 3 | First-time growers or a single-plant test run. Enough for one cycle with a spare if germination goes sideways. |
| 5 seeds | 5 | A proper personal grow. Fill a 60x60 or 80x80 tent comfortably with a Sea of Green setup. |
| 10 seeds | 10 | Serious growers who want to pheno-hunt or run a full SOG canopy. Best value per seed. |
We'd go with the 5-pack if you're growing indoors in a small tent. Ten seeds makes sense if you're running SOG and want a uniform canopy — with autos, every seed counts since you can't clone them.
Why Skywalker Auto Seeds Deserve a Spot in Your Grow Room
Greenhouse Seeds has been breeding award-winning cannabis genetics since the early '90s, and Skywalker Auto shows they know how to translate photoperiod power into autoflowering convenience. The parent genetics tell the story: Skywalker OG brings that classic OG Kush earthiness and structural density, while Gelato #41 Auto contributes the tight calyx stacking, purple colouring, and that extra layer of complexity in the terpene profile.
What makes this one stand out from the dozens of autos we carry? Three things. First, the THC ceiling — 25% is genuinely high for an autoflowering variety. Most autos top out around 18-20%, so Skywalker Auto is playing in a different league. Second, the flavour profile is properly layered. During flower, you'll smell earth, pine, and citrus. After a decent cure — give her at least two weeks in jars — the aroma deepens into something woody and herbal that smells more like a craft dispensary strain than a quick auto. Third, she stays compact at 90-110 cm, which means you're not fighting height issues in a tent.
The honest limitation? Yield. At up to 180 g per plant, Skywalker Auto isn't going to bury you in bud the way a photoperiod Skywalker OG might. That's the trade-off with any auto — you're swapping maximum yield for speed and simplicity. If you're after sheer weight, a photoperiod strain in a bigger tent with longer veg time will always win. But if you want top-shelf smoke in 9 weeks flat, with minimal effort and no light schedule management, Skywalker Auto delivers where it matters.

Running Skywalker Auto in a tent? Pair her with a complete grow kit — tent, light, ventilation, and carbon filter sorted in one go. Her compact 90-110 cm height makes her a natural fit for an 80x80 grow tent. And since she'll be putting out some serious terps during flower, a decent carbon filter isn't optional — your neighbours will thank you.
Growing Skywalker Auto Seeds: What to Expect
We've seen plenty of growers overthink autoflowers. Skywalker Auto is genuinely straightforward, but there are a few things worth knowing before you pop your seeds.
Her 90-110 cm height makes her one of the more manageable autos in the Greenhouse Seeds lineup. In a 60x60 tent, you can comfortably fit 2-3 plants. In an 80x80, go for 4 in a SOG arrangement and you'll maximise your canopy coverage. She responds well to light stress training (LST) in the first few weeks — just bend and tie, don't top her. Topping autos is a gamble because they can't recover veg time, and with only 9 weeks total, you don't want to set her back.
The buds themselves are a proper sight. Expect thick, dense nugs with bright green calyxes stacked tight, covered in deep purple sugar leaves once night temperatures drop below 15-18°C during late flower. If you're growing indoors, you can encourage that purple by dropping your lights-off temperature in the final two weeks. It's cosmetic, not chemical — but it looks stunning in a jar.
Outdoors, her compact size and autoflowering nature make her solid for balcony or guerrilla grows. She doesn't need a specific light cycle to flip, so you can plant her from late spring through midsummer and she'll do her thing regardless. Just make sure she gets at least 15-18 hours of direct light daily for the best results.
How to Grow Skywalker Auto Seeds
- Germinate your Skywalker Auto seeds using the paper towel method — place seeds between two damp (not soaking) paper towels on a plate, cover with a second plate, and keep at 22-25°C. Taproots should appear within 24-72 hours.
- Plant the germinated seed taproot-down into its final pot. Use 11-15 litre fabric pots with a light, airy growing medium — autos don't like transplanting, so start in the final container from day one.
- Keep your light cycle at 18/6 or 20/4 from seedling through harvest. Skywalker Auto doesn't need a 12/12 flip. More light hours means more photosynthesis and denser buds.
- Feed lightly during the first two weeks — seedlings don't need much. From week 3, introduce a mild vegetative nutrient schedule. Switch to bloom nutrients once you see the first pre-flowers, usually around week 3-4.
- Apply gentle LST from week 2-3 by bending the main stem away from centre and securing it with plant ties. Open up the canopy to let light reach lower bud sites. Avoid topping or heavy defoliation — she only has 9 weeks, and recovery time costs yield.
- Monitor humidity closely during flower. Skywalker Auto produces dense buds that are susceptible to mould if humidity climbs above 50% in the final weeks. Good airflow and extraction are critical.
- Flush with plain water for the final 7-10 days before harvest. Watch the trichomes with a jeweller's loupe — harvest when roughly 70% are milky with 20-30% amber for the full-bodied effect this strain is known for.
- Dry in a dark room at 18-20°C and 55-60% humidity for 7-10 days, then cure in glass jars for at least 14 days. The woody, herbal terpene profile of Skywalker Auto really opens up after a proper cure — don't rush this step.
Skywalker Auto Terpene Profile and Aroma
This is where Skywalker Auto genuinely impresses for an autoflower. During the flowering phase, she fills the room with a layered scent — earthy base notes, a sharp pine middle, and a citrus brightness on top. It's not a one-note smell. If you've grown OG Kush-family strains before, you'll recognise that deep, almost damp-earth funk underneath everything.
Once dried and cured, the profile shifts. The citrus recedes and a woody, herbal character takes over. The smoke itself is thick and smooth — not harsh, not wispy. On the exhale, there's a refreshing earthy-citrus quality that lingers. It's the kind of flavour that makes you pause and actually taste it rather than just inhale and move on. Compared to something like a straight Gelato auto, Skywalker Auto leans more savoury than sweet — think forest floor rather than dessert counter.
Skywalker Auto Effects: What Smokers Report
With up to 25% THC and a 50% indica genetic backbone, Skywalker Auto delivers effects that start in the head and settle into the body. Users report a smooth mental lift that comes on within minutes — clear-headed and focused rather than foggy. That initial cerebral phase gradually gives way to a relaxing physical sensation that eases tension in the shoulders, back, and legs without pinning you to the sofa.
It's the kind of effect profile that works for a quiet evening rather than a full knockout. You can still hold a conversation, watch a film, or potter about the kitchen. The indica side keeps things grounded without the heavy sedation you'd get from a pure indica. If you're comparing to other autos in the Greenhouse Seeds catalogue, Skywalker Auto sits between a daytime sativa-leaning hybrid and a full couch-lock indica — right in that productive-relaxation sweet spot.
Frequently Asked Questions
How long does Skywalker Auto take from seed to harvest?
Approximately 9 weeks from germination to harvest. That's the full cycle — no separate veg and flower phases to manage. She'll start showing pre-flowers around week 3-4 automatically.
What yield can I expect from Skywalker Auto?
Up to 180 grams per plant under optimal conditions. In a SOG setup with 4 plants in an 80x80 tent, you're looking at a potential total of around 500-700 grams depending on your light, nutrients, and experience level.
Can I top Skywalker Auto plants?
We wouldn't recommend it. Autoflowers have a fixed life cycle and can't recover lost vegetative time. Topping can stunt growth and reduce final yield. Stick with LST — bending and tying — to open up the canopy without stressing the plant.
Is Skywalker Auto suitable for outdoor growing?
Yes. Her compact 90-110 cm height and autoflowering nature make her well-suited for balcony grows, small gardens, or guerrilla setups. She doesn't depend on a specific light cycle, so you can plant from late spring through midsummer in most European climates.
What's the difference between Skywalker Auto and photoperiod Skywalker OG?
Skywalker Auto finishes in 9 weeks total and doesn't need a 12/12 light flip. The trade-off is yield — photoperiod Skywalker OG can produce significantly more per plant with extended veg time. Potency and terpene profile are comparable, though the auto leans slightly lighter in overall intensity.
How tall does Skywalker Auto grow?
Between 90 and 110 cm in most conditions. She's compact enough for a 60x60 tent but will fill out nicely in an 80x80 with LST applied. Outdoor plants in direct sun may push toward the upper end of that range.
Does Skywalker Auto turn purple?
Yes — the Gelato #41 genetics contribute deep purple sugar leaves, especially when night temperatures drop below 15-18°C during late flower. Indoors, you can encourage this by lowering your lights-off temperature in the final two weeks.
