Amnesia Haze Automatic Royal Queen Seeds – Fast Autoflowering Sativa Hybrid with Uplifting High & Citrus Aroma

Amnesia Haze Automatic Royal Queen Seeds delivers the iconic sativa buzz in a fast, low-maintenance autoflowering package—ready in just 10–12 weeks with euphoric highs and a zesty, earthy aroma that fills the room.

Still stuck with slow-growing photoperiods that demand months of attention? You’re not alone. Most growers only use one strain type, locking themselves into long cycles, complex light schedules, and endless waiting. That limits your freedom, takes up space, and delays the fun.

Sticking to just one growing style means missing out. You end up with more gear, higher electricity bills, and less room to experiment. Worse, you might never discover how a fast, reliable auto can fit perfectly into your life—whether you're a beginner or just want a no-fuss harvest.

Amnesia Haze Automatic changes the game. It brings the legendary sativa energy of the original Amnesia into a compact, fast-maturing plant that thrives both indoors and outdoors. With minimal effort, you get big yields, a clear-headed high, and the freedom to grow more, faster, and smarter—no light timers, no stress.

Indoor Powerhouse: Big Yields in Tight Spaces

When you grow Amnesia Haze Automatic indoors, you’re getting a vigorous sativa that doesn’t need a palace. It reaches 0.80–1.10 m (2.62–3.61 ft), making it perfect for SOG or SCROG setups under 600W HPS or full-spectrum LEDs. With dense, foxtail-like colas and up to 400 g/m² (11.34 oz/ft²), this auto fills your space with resin-rich buds in just 80–85 days from seed.

The spicy-citrus aroma blooms during late flowering, so run a carbon filter if discretion’s key. Keep temps at 22–26 °C in veg and 20–25 °C in bloom, with humidity at 50–60% early on, dropping to 40–50% near harvest. For strong roots from the start, consider Root Stimulator de B.A.C to boost early development.

Outdoor Freedom: Discreet, Resilient & Ready Fast

Outdoors, Amnesia Haze Automatic thrives in warm, sunny climates—think Mediterranean or long-summer regions. It grows up to 1.20 m (3.94 ft) and produces up to 180 g/plant (6.35 oz/plant), especially when planted in well-draining soil with plenty of sunlight. Its sativa structure and open branching allow for excellent airflow, reducing mold risk.

Thanks to its Ruderalis genes, it’s more resistant to temperature swings and light stress than most sativas. Plant it in a 20L pot or directly in the ground, and let nature do the rest. For extra protection against pests and fungi, Bio Protect offers organic defense without harsh chemicals.

• If you value control and privacy, go indoor
• If you love natural light and low effort, go outdoor

Frequently Asked Questions

Can I grow Amnesia Haze Automatic outdoors in a cold climate?

Yes, but it thrives best in warm, sunny areas. If you’re in a cooler zone, grow it in a greenhouse or during the hottest months for best results.

Does this strain need a lot of nutrients?

No—Haze varieties are sensitive. Start low and go slow. Overfeeding can cause nutrient burn and reduce yields.

Can I use LST or pruning on this autoflower?

LST is fine, but avoid topping, FIM, or aggressive pruning. Autoflowers have a fixed timeline and won’t recover from heavy stress.

How tall does Amnesia Haze Automatic get?

Indoors: 0.80–1.10 m (2.62–3.61 ft). Outdoors: up to 1.20 m (3.94 ft), depending on conditions.

What does it taste and smell like?

Expect a spicy, citrusy aroma with earthy and herbal notes. The flavor is sweet and peppery, with a smooth, musky finish.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of Hazes in my time, but the Amnesia Haze Automatic from Royal Queen Seeds stands out for its balance of speed and quality. I ran three plants under a 600W LED in 20L pots, using a soil mix with perlite and a bit of coco. I started with Root Stimulator de B.A.C and saw strong root development by week two.

I used LST early to control stretch and opened up the canopy—no topping, just gentle bending. The plants grew fast, with that classic sativa vigor. I switched to bloom nutrients as pistils appeared and added P-Boost at peak flowering. The buds got dense and white with trichomes.

After 83 days, I harvested 380 g/m²—dry, cured, and absolutely fragrant. The high is clean, uplifting, and perfect for daytime creativity. If you want the real Amnesia experience without the 20-week wait, this auto is your best bet. I’d recommend it to any grower who values quality, speed, and reliability.
