Amnesia

Amnesia Feminised Seeds by Advanced Seeds

Amnesia by Advanced Seeds is a Sativa-dominant feminised cannabis seed that delivers the full genetic package of the strain many growers call the "Queen of Dutch Coffee Shops." With a flowering time of just 65–70 days, indoor yields up to 500–600g/m², and a natural resistance to pests and mould, this is the Amnesia variant you grow when you want reliable results without babysitting your plants. Advanced Seeds kept the genetics clean — no unnecessary crosses, just the classic Amnesia profile that made this strain a coffee shop staple in the first place.

Why Amnesia Seeds Deserve a Spot in Your Grow Room

There's a reason nearly every seed bank on the planet has their own Amnesia cross. The original genetics are that good. But here's the thing — not every version is worth your time or tent space. Advanced Seeds went with a straightforward approach: keep the classic Amnesia genetics intact, feminise the seeds so you're not wasting weeks on males, and let the plant do what it does naturally. No exotic backcrosses, no marketing gimmicks.

What you actually get is a plant with ridiculous growing vigour. We've seen growers describe Amnesia as "impatient to reward you," and that tracks. She pushes through veg with the kind of energy that makes you double-check your light schedule. Indoors, she stays between 70 and 150cm — manageable even in a small tent — but outdoors she'll stretch to 250–350cm if you give her the room. The natural pest and mould resistance is the quiet star here. If you've ever lost a plant to botrytis three weeks before harvest, you know how much that matters. Amnesia shrugs off conditions that would send fussier strains to the compost bin.

The one honest caveat: Sativa-dominant strains can stretch during the first two weeks of flower. If your vertical space is tight — say, a 120cm tent — you'll want to top or FIM during veg to keep the canopy flat. Amnesia responds well to both techniques, and she's a natural fit for SoG setups. But if you just let her go without any training in a short tent, she'll outgrow your light. Plan accordingly.

How to Grow Amnesia Feminised Seeds

Amnesia is forgiving enough for a first grow but rewards experienced hands with seriously impressive harvests. Here's a practical run-through.

1. Germinate your seeds using the paper towel method or directly in a small pot of moist, airy soil. Amnesia has strong germination vigour — expect taproots within 24–72 hours in most cases.
2. Transplant seedlings into their final containers once they've developed 2–3 sets of true leaves. For indoor SoG, 7–11 litre pots work well. For outdoor plants you want to reach full size, go 25 litres or more.
3. During vegetative growth, consider topping or FIMing once the plant has 4–5 nodes. Amnesia responds brilliantly to these techniques — you'll get a bushier canopy and more even bud sites, which directly translates to higher yields at harvest.
4. Switch to a 12/12 light cycle to trigger flowering. Expect some stretch in the first 10–14 days — this is normal for Sativa-dominant genetics. Keep your light at the right distance to avoid bleaching the tops.
5. Maintain standard feeding through flower. Amnesia isn't particularly hungry compared to some heavy-feeding hybrids, but she'll appreciate a phosphorus-potassium boost during weeks 4–6 of bloom.
6. Monitor trichome development from day 60 onwards. The 65–70 day flowering window means you should start checking around day 58–60 with a jeweller's loupe. Harvest when trichomes are mostly milky with a few turning amber — this is where the resin production on Amnesia really shows off.
7. Dry in a dark, well-ventilated space at around 18–21°C and 55–60% humidity for 7–10 days. Cure in glass jars for a minimum of two weeks. The terpene profile develops significantly during the cure — rushing this step costs you flavour.
