Amnesia

Amnesia Feminized Cannabis Seeds by Super Strains

Amnesia is a sativa-dominant cannabis strain from Super Strains (formerly Hy-Pro Seeds) that delivers one of the strongest cerebral effects you'll find in seed form. These feminized seeds carry the original Amnesia genetics — the same lineage that's been borrowed, crossed, and entered into Cannabis Cups by other seed banks for years. If you've smoked Amnesia in an Amsterdam coffeeshop and wondered where it all started, this is it.

Why These Amnesia Seeds Stand Out

The original Amnesia genetics from Super Strains have quietly supported some of the most decorated strains in cannabis competition history. Super Strains themselves never entered a Cannabis Cup — but other seed companies took these genetics, made their own crosses, and walked away with trophies. That tells you something about the foundation you're working with here.

We've carried Amnesia seeds for years, and the feedback from growers is consistent: the effect is overwhelmingly strong. This isn't a gentle afternoon smoke. The sativa-dominant profile hits hard and lifts you into a headspace that experienced smokers describe as electric, clear, and long-lasting. According to research published in PMC, cannabis administration is associated with altered cognitive processing, which in the case of strong sativa strains like Amnesia translates to that characteristic "where did I put my keys" intensity (PMC4552130).

One honest note: this isn't the easiest strain to grow if you're brand new. The 10-week flowering period demands patience, and the plant stretches tall — up to 3 metres outdoors. Indoors, you'll need to manage height with training techniques or an early flip to flower. But the smoke quality at the end? That's what keeps growers coming back to Amnesia year after year.

How to Grow Amnesia Feminized Seeds

Amnesia rewards growers who plan ahead. The combination of a long flowering window and vigorous vertical growth means you need a strategy before you pop the seed. Here's what works:

1. Germinate your Amnesia seeds using the paper towel method or directly in a small pot of moist, airy soil. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final container once they've developed 2–3 sets of true leaves. A 15–20 litre pot works well for indoor grows.
3. Keep the vegetative period short indoors — 3 to 4 weeks maximum. Amnesia stretches significantly once you flip to 12/12, sometimes doubling in height during the first 2–3 weeks of flower.
4. Apply low-stress training (LST) or a screen of green (ScrOG) to control height and expose lower bud sites to light. This strain responds well to being bent and tied down.
5. Switch to a 12/12 light cycle to trigger flowering. Expect a full 10 weeks before harvest — don't rush it. The final 2 weeks are where Amnesia develops that characteristic resinous finish.
6. Monitor trichomes with a jeweller's loupe. Harvest when trichomes are mostly cloudy with a few amber heads for the full sativa effect. More amber shifts the profile towards a heavier feel, which somewhat defeats the purpose of growing a Haze.
7. Dry slowly in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks. Amnesia's terpene profile develops noticeably during a proper cure.

What Amnesia Smells and Tastes Like

Crack open a jar of properly cured Amnesia and the first thing that hits you is a sharp, earthy citrus — somewhere between lemon peel and damp forest floor, with a peppery Haze funk underneath. It's not subtle. Your carbon filter earns its keep during the last 3 weeks of flower.

The smoke itself carries that classic Haze profile: a spicy, almost incense-like inhale that opens up into bright citrus on the exhale. If you've smoked Amnesia Haze in a coffeeshop on the Warmoesstraat, you know exactly what we're talking about. The taste lingers — you'll still notice it 10 minutes after your last pull.

Compared to something like Super Silver Haze or Neville's Haze, Amnesia leans heavier on the earthy side with less of that pure tropical sweetness. It's a more grounded Haze, if that makes sense — still unmistakably sativa in character, but with a bit more depth in the flavour.

Amnesia Sativa Effects and What to Expect

Amnesia is considered one of the strongest sativa strains available in seed form, and that reputation is well-earned. The effect is intensely cerebral — a fast-onset wave of mental energy that can feel almost electric in the first 15 minutes. Experienced smokers love it. Newcomers should approach with genuine respect.

According to a review published in Experimental and Clinical Psychopharmacology, chronic and heavy cannabis use is associated with increased risk of cognitive impairment (Broyd et al., 2016; Curran et al., as cited in PMC6416743). With a strain this potent, moderation isn't just advice — it's common sense. One or two pulls is plenty to gauge where you're at before going further.

A study on cannabis and memory consolidation noted that effects on different cognitive domains vary with dose and frequency of use (PMC9855787). The "amnesia" name isn't just marketing — strong sativa strains like this one can genuinely make you lose your train of thought mid-sentence. That's part of the appeal for some, and a reason to dose carefully for others.

The one limitation worth flagging: because the effect is so heady and stimulating, some people find it uncomfortable if they overdo it. Dry mouth and racing thoughts are the most commonly reported downsides. If you're sensitive to strong sativas, start small.

Amnesia vs Other Haze Strains

If you're weighing Amnesia against other sativa-dominant options, here's how the original stacks up:

The key difference: Super Strains holds the original genetics. Other seed banks have taken Amnesia and crossed it into their own versions — some of which have won Cups directly. But if you want the source material, the unaltered original, this is the only feminized option.
