Amnesia Ryder Autoflower Cannabis Seeds
Amnesia Ryder Autoflower is a sativa-dominant autoflowering cannabis seed from World of Seeds that packs a complex genetic lineage — Thai, Skunk, Cinderella 99, Jack Herer, and Ruderalis — into a plant that finishes its entire life cycle in 60–70 days. If you want the soaring, energetic sativa high that Amnesia genetics are famous for, but you don't want to mess about with light schedules or wait four months, this is your shortcut.
Why Amnesia Ryder Autoflower Seeds Stand Out
World of Seeds didn't just slap a Ruderalis cross onto a random Amnesia cut and call it a day. The parent Amnesia is itself a four-way cross — Thai, Skunk, Cinderella 99, and Jack Herer — each contributing something specific. Thai brings that classic racy sativa energy. Skunk adds structure and reliability. Cinderella 99 pushes resin production. Jack Herer rounds it out with vigour and complexity. The Ruderalis element strips away photoperiod dependency without gutting the sativa character, which is the bit most autoflower breeders struggle with.
The result is a plant that grows past 120cm — tall for an auto — and produces indoor yields of 450–550g/m² under optimal conditions. Outdoors, expect up to 200g per plant. Those numbers are genuinely impressive for an autoflowering strain that wraps up in just over two months. Bud density and resin production are both strong points, and the built-in mould and pest resistance means less babysitting during the grow.
We'd pick Amnesia Ryder over most other sativa autos purely on flavour. The dominant note is citrus — sharp, clean, almost lemon-peel bright — layered over subtler Skunk earthiness, a whisper of Jack Herer spice, and a faint tropical sweetness from the Thai genetics. It's a complex profile that rewards slow, deliberate tasting rather than rushing through a joint. The high matches: intense, energetic, upward. Not a couch strain. Not remotely.

Amnesia Ryder vs Other Sativa Autoflowers
Most sativa-leaning autos compromise somewhere — either the plant stays short and yields drop, or the sativa high gets diluted into something bland and indistinct. Amnesia Ryder manages to keep the height (120cm+), the yield (up to 550g/m² indoors), and the sharp sativa character intact. Compared to something like Amnesia XXL Auto, which can grow even bushier and faster, Amnesia Ryder tends to produce a more refined flavour profile thanks to that Cinderella 99 and Thai parentage. If raw bulk is your priority, XXL might edge ahead. If flavour complexity and a clean cerebral high matter more, Amnesia Ryder wins.

Growing Amnesia Ryder indoors? Pair these seeds with a complete grow tent kit — tent, lighting, ventilation, and carbon filter in one box. Outdoors, a set of fabric pots and organic soil mix will let this strain's natural vigour do the heavy lifting.
How to Grow Amnesia Ryder Autoflower Seeds
Amnesia Ryder is forgiving enough for a first autoflower grow, but a few things will make the difference between a decent harvest and a properly impressive one. Here's the practical rundown:
- Germinate your seeds using the paper towel method or directly in a small pot of moist, airy soil. Taproots typically appear within 24–72 hours.
- Plant the germinated seed about 1cm deep in its final container — autoflowers don't love transplanting. A 15–20 litre fabric pot works well. Use a light, well-draining soil mix.
- Set your light schedule to 18/6 or 20/4 from day one. Unlike photoperiod strains, Amnesia Ryder doesn't need a 12/12 flip to trigger flowering — it'll start on its own around week 3–4.
- Keep humidity around 60–70% during the seedling stage, dropping to 40–50% once flowers develop. Temperature should sit between 20–26°C. This strain handles fluctuations reasonably well thanks to its Ruderalis backbone.
- Feed lightly during the first two weeks — autoflowers are sensitive to overfeeding early on. Ramp up nutrients during the flowering stretch, focusing on phosphorus and potassium from week 4 onward.
- Expect the plant to stretch past 120cm. If vertical space is tight, gentle LST (low-stress training) in the first three weeks keeps the canopy even without stressing the plant into slowing down.
- Harvest around day 60–70 when trichomes shift from clear to milky-white. For a more cerebral, energetic effect, harvest when most trichomes are milky with minimal amber.
Who Should Grow Amnesia Ryder Autoflower
This strain works best if you want sativa-quality smoke without a sativa-length grow cycle. The 60–70 day turnaround means you can run multiple cycles per season outdoors, or squeeze in extra harvests indoors. The high mould and pest resistance makes it a solid pick for growers in less-than-ideal climates — think the UK, northern Germany, the Netherlands, Scandinavia.
If you're chasing maximum indica sedation, look elsewhere. Amnesia Ryder delivers an intense, energetic, upward high that's firmly in sativa territory. Sativa lovers will genuinely appreciate what World of Seeds has done here — they've kept the character of the original Amnesia genetics intact while making the whole thing dramatically easier to grow.
Frequently Asked Questions
How long does Amnesia Ryder Autoflower take from seed to harvest?
60–70 days from germination to harvest. That's the full life cycle — no separate vegetative and flowering periods to manage. Some phenotypes lean closer to 60 days, others push toward 70 depending on conditions and feeding.
What yield can I expect from Amnesia Ryder Autoflower indoors?
Under optimal conditions — proper lighting, nutrients, and climate control — indoor yields reach 450–550g/m². In a standard 1m² tent with good LED lighting, 450g is realistic for a competent grower. The upper range requires dialled-in conditions.
Does Amnesia Ryder Autoflower need a light schedule change to flower?
No. As an autoflowering strain, Amnesia Ryder transitions to flowering automatically around week 3–4 regardless of light schedule. Most growers run 18/6 or 20/4 throughout the entire cycle for best results.
Is Amnesia Ryder suitable for outdoor growing in northern Europe?
Yes, and it's actually one of the better choices for cooler, damper climates. The high mould and pest resistance inherited from its genetics means it handles northern European conditions well. Outdoor yields can reach 200g per plant.
What does Amnesia Ryder Autoflower taste like?
The dominant flavour is a sharp citrus — think lemon peel — with underlying layers of Skunk earthiness, Jack Herer spice, and a faint tropical sweetness from the Thai genetics. It's a complex blend that comes through best when properly flushed and cured.
How tall does Amnesia Ryder Autoflower grow?
Plants commonly exceed 120cm, which is tall for an autoflower. Indoor growers with limited vertical space should apply low-stress training during the first three weeks to manage height. Outdoors, let it stretch — the extra height translates to bigger yields.
Is Amnesia Ryder Autoflower good for beginners?
It's a reasonable choice for a first autoflower grow. The mould resistance and short life cycle are forgiving, but the height can surprise new indoor growers. Start with LST early and don't overfeed in the first two weeks. The Ruderalis genetics add a layer of resilience that more finicky sativa strains lack.
