Alpujarreña Auto by Pyramid Seeds – Fast-Flowering Indica Dominant Strain with Sweet Aroma & 18% THC

Alpujarreña Auto by Pyramid Seeds is a tough, fast-flowering autoflowering strain with a sweet aroma, 18% THC, and impressive resilience—perfect for stress-free growing in any environment.

Struggling with harsh climates or short seasons?

Many growers lose crops to cold snaps, mold, or unpredictable weather—especially when growing photoperiod strains that need long, stable summers. If you're in a region with short summers or erratic conditions, timing your harvest can feel like gambling.

What if your plant could handle the cold and still deliver top-shelf bud?

Imagine a strain so tough it thrives above 1,000 meters in the Sierra Nevada, where nights are freezing and winds are fierce. Now imagine it flowers automatically, no light cycle changes needed, and finishes in under 11 weeks. That’s not fantasy—that’s Alpujarreña Auto.

How to grow Alpujarreña Auto like a pro (in 5 simple steps)

3. Keep light at 18/6 or 20/4 all cycle – no changes needed, just consistency
4. Monitor pH: 6.0–6.5 in soil, 5.8–6.2 in hydro/coco – stability prevents stress

Frequently Asked Questions

Is Alpujarreña Auto good for beginners?

Absolutely. It’s one of the easiest autoflowers to grow—resilient, forgiving, and low-maintenance. Just provide light, water, and a decent pot, and it’ll reward you.

Can I grow it outdoors in cold climates?

Yes. It’s specifically bred for high altitudes and cold conditions. As long as you plant it during peak sunlight, it’ll thrive even in northern Europe or mountainous regions.

Does it need pruning or training?

Minimal. A light topping or LST is fine early on, but avoid aggressive pruning—autoflowers don’t recover well. Let it grow naturally for best results.

What’s the flavor and effect like?

Sweet and earthy with a smooth smoke. The 18% THC delivers a calming, full-body relaxation—perfect for unwinding at night without heavy sedation.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Alpujarreña Auto on my rooftop in Barcelona during a surprisingly cold spring. Most of my other plants struggled, but this one just kept pushing—thick, bushy, and covered in resin by week 8. I didn’t touch it with scissors, just a little LST to open the canopy. Harvested at 54 days, and after a 3-week cure, the buds were dense, frosty, and smelled like sweet mountain air. The high is deep but not couch-locking—great for chilling after work. It’s now a staple in my seasonal rotation, especially for stealth grows or quick turnarounds. If you want a strain that just works, this is it.
