Auto Alpujarreña Cannabis Seeds by Pyramid Seeds
Auto Alpujarreña is an autoflowering feminised cannabis seed that produces a compact, cold-resistant plant with 17% THC and a relaxing indica-dominant profile. Bred by Pyramid Seeds across multiple generations in the Alpujarras mountains of Granada, Spain, this strain shrugs off cold snaps and wind that would flatten flimsier genetics. If you want to buy a low-fuss autoflower that actually tastes good and finishes fast, she belongs on your shortlist.
Why Auto Alpujarreña Seeds Stand Out
Auto Alpujarreña was bred for mountain resilience first — speed and convenience came second. Pyramid Seeds grew generation after generation in the Alpujarras mountain range, that rugged terrain south of Granada where temperatures swing hard between day and night and the wind doesn't let up. The result is a plant with genuinely sturdy branches and a natural tolerance for cold that you won't find in your average auto.
At 40–100cm, she stays short. Really short, in some cases. That makes her a strong pick for balcony grows, small tents, or any situation where discretion matters. We've seen growers tuck autos like this behind tomato plants and nobody bats an eye. The compact structure also means she doesn't need much vertical space indoors — an 80x80 tent handles her easily with room to spare for a few companions.
The flavour profile is where she quietly impresses. Pyramid Seeds' Granada genetics bring a sweet, earthy aroma with enough complexity to keep things interesting. The smoke is smooth, the taste lingers, and at 17% THC, the effect is a proper indica wind-down — heavy relaxation without completely nailing you to the sofa. Good for an evening session, not so much for a productive afternoon.

Auto Alpujarreña Yield and Flowering Performance
Auto Alpujarreña yields up to 550g/m² indoors and around 100g per plant outdoors, with a 50–55 day flowering window that ranks among the shortest we carry. Those numbers are genuinely competitive for an auto this small — she sits in the same conversation as autos twice her height. The speed also opens up the possibility of squeezing in a second run if your growing season allows it.
From seed to harvest, you're looking at roughly 70–80 days total. For context, many popular autos take 75–90 days just to flower. If patience isn't your strong suit — and honestly, whose is it when there's a plant involved — this strain rewards you faster than most.
One honest limitation: the 40–100cm height range is wide. Under strong indoor lighting with good nutrition, she'll push towards that upper end. On a windowsill or in suboptimal conditions, she may stay closer to 40cm, and a 40cm auto won't yield anywhere near 550g/m². Environment matters more than genetics at that point. Give her decent light and she'll give you decent bud — it's a fair trade.
Growing Auto Alpujarreña — What to Expect
Growing Auto Alpujarreña is about as forgiving as cannabis cultivation gets. The autoflowering genetics mean no light-cycle management, the feminised seeds mean no males to cull, and the mountain-bred resilience means she handles temperature drops, gusty conditions, and the occasional beginner mistake without drama.
- Germinate your seeds using the paper towel method or directly in a small pot of lightly moistened soil. Taproots typically appear within 24–72 hours.
- Transplant seedlings into their final container early — autos don't love being moved once established. A 10–15 litre pot works well for this strain's compact root structure.
- Provide 18–20 hours of light per day indoors throughout the entire lifecycle. Outdoors, plant after the last frost, though this strain handles cooler nights better than most.
- Feed lightly during the vegetative stage. She's a small plant and doesn't need heavy nutrition — overfeeding is a more common mistake than underfeeding with compact autos.
- Switch to bloom nutrients when you see the first pistils, typically around week 3–4 from seed. The 50–55 day flowering clock starts here.
- Harvest when trichomes shift from clear to milky-white with some amber. Given the indica dominance, a slightly later harvest (more amber trichomes) will push the effect further towards deep relaxation.
Auto Alpujarreña vs Other Compact Autoflowers
Auto Alpujarreña outperforms most compact autos on cold resistance and flowering speed, while matching or exceeding them on indoor yield. If you're comparing within the Pyramid Seeds range, the closest competitor is Auto Tutankhamon — but that's a sativa-leaning AK-47 cross with higher THC and a completely different effect profile. Tutankhamon is the energetic one; this Granada-bred strain is the one that puts you in a hammock.
| Feature | Auto Alpujarreña | Typical Compact Auto |
|---|---|---|
| Flowering Time | 50–55 days | 60–70 days |
| Height | 40–100cm | 50–120cm |
| Cold Resistance | Excellent (mountain-bred) | Moderate |
| Indoor Yield | Up to 550g/m² | 350–450g/m² |
| THC | 17% | 15–20% |
| Dominant Effect | Deep relaxation, calming | Varies |
The cold resistance is the real differentiator. We'd pick this strain over most autos for northern European outdoor grows, balcony setups in exposed locations, or any situation where you can't fully control temperature. She was literally bred for it.
Growing indoors? Pair her with a compact grow tent and a basic LED setup — her short stature means you don't need tall equipment. A carbon filter is worth adding too, especially if you're going for the stealth angle. For outdoor grows, a few fabric pots and some quality soil mix will set you up nicely.

Who Should Buy Auto Alpujarreña Seeds
First-time growers should get Auto Alpujarreña as their starter strain — the combination of autoflowering genetics, feminised seeds, compact size, and mountain-bred toughness removes most of the variables that cause beginners trouble. You don't need a sophisticated setup. You don't need years of experience. You need a pot, some soil, light, and a bit of patience — though not much, given the 50–55 day flowering time.
She's also a solid pick for experienced growers running a Sea of Green setup. The short, uniform structure lends itself to packing multiple plants per square metre, and the fast turnaround means you can run several cycles per year indoors. At up to 550g/m², the maths works out well.
The one grower who might want to look elsewhere: anyone chasing maximum THC. At 17%, this strain delivers a satisfying, calming smoke, but she's not competing with 25%+ strains. That said, 17% with good terpenes and a clean indica effect often feels stronger than the numbers suggest. Potency isn't just about percentages — flavour and terpene profile shape the experience more than most people realise.
Frequently Asked Questions
How long does Auto Alpujarreña take from seed to harvest?
Roughly 70–80 days total. The flowering period is 50–55 days, with about 3–4 weeks of vegetative growth before that. She's one of the fastest autos we carry.
Can Auto Alpujarreña handle cold climates?
Yes — this is her strongest trait. Bred at high altitude in the mountains of Granada, she tolerates cold nights and temperature swings that would stress most autoflowers. She's a strong choice for northern European outdoor grows.
What yield can I expect outdoors?
Up to 100g per plant outdoors. Actual yield depends heavily on light exposure, soil quality, and container size. In a sunny, sheltered spot with a 15-litre pot, you'll get closer to that upper figure.
Is this strain suitable for stealth growing?
Absolutely. At 40–100cm, she stays compact enough to grow on a balcony, in a small cupboard, or tucked among other plants. The short flowering time also reduces the window of detection.
How does she compare to other Pyramid Seeds autoflowers?
She's the cold-weather specialist. Auto Tutankhamon from Pyramid Seeds offers higher THC and a more energetic effect, but lacks the mountain-bred resilience. This is the one you pick when conditions are tough and you want reliability over raw potency.
Do these seeds need a specific light cycle?
No. As an autoflower, she flowers based on age, not light schedule. Most growers run 18–20 hours of light throughout the full lifecycle for best results indoors. Outdoors, she'll flower regardless of day length.
What does the smoke taste like?
Sweet and earthy with a smooth, lingering finish. The Granada mountain genetics give her a distinctive flavour that's more complex than your average auto — think warm, slightly spiced sweetness rather than one-note fruit.
