Amnesika 2.0 Feminized Seeds – Philosopher Seeds' High-THC Haze Powerhouse

Amnesika 2.0 feminized seeds from Philosopher Seeds give you a high-THC, high-yield powerhouse with a fast finish and explosive growth—perfect for growers who want maximum impact with minimal fuss.

Struggling with weak yields and slow finishes?

You’ve grown sativas before—long waits, spindly plants, and disappointing harvests. You want that cerebral punch, but not at the cost of three extra months or a jungle of weak stems.

What happens if you keep settling for underperforming sativas?

You waste time, space, and energy on plants that stretch too much, mold easily, or barely cover the trim tray. You miss the sweet spot between potency and practicality—ending up with either great flavor or decent yield, never both.

The solution: a sativa-dominant hybrid bred for power and speed

Amnesika 2.0 combines the legendary Amnesia Haze with Critical Mass to give you the best of both worlds: the soaring high of a Haze and the dense, resinous buds of an indica powerhouse. This isn’t just another photoperiod strain—it’s a yield monster with a 55–65 day flowering cycle and THC levels hitting 21%. Whether you're running an indoor SOG setup or growing outdoors in the Mediterranean sun, this strain delivers up to 600 g/m² indoors and over 2 kg (4.41 lb) per plant outside.

Massive harvests without the wait

Amnesika 2.0 explodes in growth and finishes fast, making it ideal for high-density grows. Its 70% sativa dominance gives you a strong, uplifting high, while the indica backbone keeps the plant compact and manageable. With medium internodal spacing and minimal foliage, manicuring is a breeze—no more spending hours trimming leafy colas.

How to grow Amnesika 2.0 for maximum yield

Get the most out of Amnesika 2.0 with this expert-backed grow guide tailored to its sativa vigor and indica resilience.

Quick overview: Feminized sativa-dominant hybrid · Philosopher Seeds · 55–65 day flowering · ideal for indoor SOG or outdoor in warm climates.

Safe start: Germinate in a moist, dark environment at 22–25 °C. Transplant once the taproot reaches ~1 cm (0.39 in). For stronger roots, consider Natural Clone de Trabe to boost early development.

Directed growth: Use 18/6 light cycle. Keep pots at 11–20 L depending on space. Prune lower branches to focus energy on top colas. This strain thrives in Coco Mix 50L for excellent drainage and root aeration.

Efficient flowering: Switch to 12/12 light. Maintain RH at 40–50% to prevent mold. Support heavy buds with stakes or a SCROG net. Apply Top Bloom in mid-flower to enhance resin and density.

Harvest and refinement: Harvest when trichomes turn milky to amber for a balanced high. Flush 7–10 days before harvest. Dry at 18–22 °C and 50–60% RH for 10–14 days, then cure for 2–4 weeks in jars.

Frequently Asked Questions

Is Amnesika 2.0 good for beginners?

Yes. It’s easy to grow, forgiving of minor mistakes, and adapts well to different setups—just control humidity and support the buds.

How tall does Amnesika 2.0 get outdoors?

It can exceed 2 m (6.56 ft), especially in optimal conditions. Use 11–40 L pots to manage size and ensure discretion on balconies.

Does it need training?

Not required, but LST, topping, or SCROG can significantly increase yields by exposing more bud sites to light.

Can I grow it in a small indoor space?

Absolutely. With SOG setups (25–30 plants/m²) and 2–3 weeks of veg, it stays under 110 cm (3.61 ft) while still delivering massive yields.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Amnesika 2.0 last season in my 1.20 x 1.20 m (3.94 x 3.94 ft) tent with 600W LED. I ran a SOG setup with 25 plants in 11L pots. After just 3 weeks of veg, I switched to flowering. The stretch was moderate—about 40% taller—but the structure held strong. I used a SCROG net to spread the canopy, and by week 4, it was a solid blanket of buds.

I fed her with a balanced coco A/B and added Top Bloom from week 3 of flower. The smell was intense—classic Haze with that skunky punch—so I had to run my carbon filter 24/7. At 63 days, trichomes were mostly milky with a few amber heads. I flushed for 10 days, dried slowly, and cured for three weeks.

The yield? 587 grams (20.71 oz) of dense, frosty buds. The high hits fast and hard—euphoric, creative, then deeply relaxing. Not a strain for productivity, but perfect for unwinding. If you want a high-THC sativa that doesn’t take forever and actually fills the jar, this is your go-to.
