Amnesia Auto Nirvana – Sativa-Dominant Autoflower with Citrus Punch & 16–20% THC

Amnesia Auto Nirvana is a sativa-dominant autoflowering strain from Nirvana Seeds that delivers a long-lasting, euphoric high and explosive citrus terpene profile in just 11–13 weeks from seed to harvest, making it a top choice for sativa lovers who want speed and power without compromise.

Are you tired of waiting months for a proper sativa buzz, only to end up with weak flavors and underwhelming effects? You’re not alone. Most autoflowers sacrifice potency and aroma for speed — leaving you with a forgettable smoke that doesn’t match the legendary haze experience.

That wait-and-disappointment cycle kills the vibe before you even light up. You invest time, space, and energy only to get flat-tasting buds and a short-lived high that doesn’t keep you creative or focused. And if you’re growing in a tight space or a less-than-ideal climate, the stress of mold or stretching plants adds even more pressure. The result? Frustration, wasted effort, and a stash that doesn’t inspire.

Amnesia Auto Nirvana flips the script. With genetics rooted in the world-famous Amnesia Haze and stabilized by robust Ruderalis, this autoflower gives you the full cerebral rollercoaster — fast. You get massive yields, tropical-citrus terpenes, and a THC range of 16–20%, all in a compact, resilient plant that thrives indoors or outdoors. No more compromises. Just pure, potent, uplifting energy on your schedule.

More Discretion, Fewer Worries

Even with its sativa structure, Amnesia Auto Nirvana stays manageable at 1.20–1.50 m (3.94–4.92 ft), making it ideal for balconies, small grow tents, or discreet outdoor setups. Its rapid 11–13 week cycle means less time exposed and fewer chances for unwanted attention. The sharp citrus and earthy aroma is noticeable but not overwhelming — especially when grown with proper ventilation. Pair it with a carbon filter from our grow shop and you’ve got a stealthy sativa machine that flies under the radar.

Stages and Monitoring of Amnesia Auto Nirvana

Get the most out of your Amnesia Auto grow with this concise, phase-by-phase guide — designed for speed, yield, and flavor.

Quick overview: Sativa-dominant autoflower from Nirvana Seeds, 11–13 week cycle, medium difficulty, ideal for sunny or warm climates and SOG setups.

Safe start: Germinate in a warm, dark, moist environment. For faster rooting and stronger seedlings, Root It 150ml boosts early development and reduces transplant shock.

• Soak seeds in water or use paper towel method at 22–25 °C
• Transplant when taproot is ~1 cm long
• Use small pots or starter cubes to minimize stress
• Keep humidity high (60–70%) and light gentle
• Apply mild nutrients only after first true leaves appear

Stable seedling: Focus on root health and steady growth. Avoid overwatering and ensure good airflow.

• Water when topsoil feels dry
• Use a fan for gentle airflow to strengthen stems
• Begin light feeding with nitrogen-rich formula
• Consider mycorrhizae to enhance nutrient uptake
• Transplant to final 18–27 L pot by week 2–3

Directed growth: Support stretch and structure. This strain grows fast — stay ahead with proper spacing and support.

• Use LST to control height and expose more bud sites
• Train early, before pre-flower stretch begins
• Provide strong, even light coverage (LED or HPS)
• Feed progressively — increase nutrients as plant grows
• Monitor pH and EC to avoid nutrient lockout

Efficient flowering: Maximize resin and density. This is where Amnesia Auto shines — keep conditions stable and support heavy colas.

• Expect flowering to begin automatically around week 4
• Reduce humidity to 40–50% to prevent mold
• Use a trellis or stakes for branch support
• Boost with bloom stimulants like Top Candy during peak flowering
• Watch trichomes — harvest when mostly milky for maximum euphoria

Harvest, drying and curing: Lock in flavor and potency. Patience here pays off.

• Flush 7–10 days before harvest with plain water
• Cut branches and hang upside down in dark, 18–22 °C space
• Keep humidity at 50–60% during drying (5–7 days)
• Cure in jars for 2–4 weeks, opening daily for first week
• Enjoy smooth, terpene-rich smoke with long-lasting effects

Yes, it’s a heavy feeder. Gradually increase nutrients during growth, but avoid overfeeding — especially in coco or hydro setups.

Is Amnesia Auto good for beginners?

It’s medium difficulty due to its sativa stretch and feeding needs, but very rewarding. Best for growers with some experience or those ready to learn.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of hazes in my time, but Amnesia Auto Nirvana stands out because it delivers that classic Amsterdam coffee shop high — fast. I ran it in a 1.2 m x 1.2 m tent under a 600W LED, with five plants in 20L pots. I used LST from day one to keep them wide and even. By week 4, they started flowering and shot up fast — one hit 1.45 m! I staked them early and used a SCROG net to hold the weight. The citrus punch when flowering started was unreal — filled the whole grow room. I fed heavy, used Top Candy in mid-flower, and harvested at 90 days. Dried and cured for three weeks. The high is pure euphoria — sharp, creative, lasts for hours. Perfect for weekend projects or long sessions with friends. If you want a real sativa experience without the 4-month wait, this is your strain.
