Blue Amnesia Autoflower Cannabis Seeds
Blue Amnesia Autoflower is an autoflowering feminised cannabis seed from Amsterdam Genetics that crosses legendary Amnesia genetics with the celebrated Blue Dream strain. The result is a 60% sativa / 40% indica hybrid that flowers on its own schedule, produces serious yields, and delivers a flavour profile that sits somewhere between sweet berry and spicy haze. Available in packs of 3, 5, or 10 seeds.
This product is intended for adults aged 18 and over.
Choose Your Pack Size
| Pack | Seeds | Best For |
|---|---|---|
| 3 seeds | 3 | First-time growers wanting to test the strain without committing |
| 5 seeds | 5 | A solid indoor run — enough for a full tent with a spare |
| 10 seeds | 10 | Outdoor growers or anyone planning multiple cycles |
We'd pick the 5-pack for most indoor setups. Three seeds feels tight if one doesn't pop, and ten is more than you need unless you're running a proper outdoor plot or want to pheno-hunt a bit.

Running Blue Amnesia Autoflower indoors? Pair her with a proper grow tent and a carbon filter setup to keep the spicy-sweet terps from announcing themselves to the whole building. A pH meter is worth grabbing too — autos are less forgiving of root-zone issues because you can't extend veg to recover.
Why Grow Blue Amnesia Autoflower Seeds
Amnesia has been a coffeeshop staple for years — the kind of strain that people keep coming back to because it just works. Amsterdam Genetics clearly knew they had strong foundations to build on, but instead of releasing yet another photoperiod Amnesia cross, they did something more interesting. They brought in Blue Dream genetics, flipped it to autoflower, and created a hybrid that genuinely stands apart from the dozens of Amnesia variants floating around.
The sativa-dominant genetics (60/40 split) give you that uplifting, cerebral character you'd expect from an Amnesia cross, but the 40% indica side — courtesy of Blue Dream — adds physical weight to the effect. According to a classification study analysing various Amnesia-lineage cultivars, Amnesia Haze-type genetics show distinctive sativa-dominant cannabinoid and terpene profiles that differentiate them clearly from indica varieties (Ferreiro-Vera et al., 2022). That sativa backbone is what gives Amnesia crosses their signature character, and Blue Amnesia Autoflower keeps it intact while layering on something new.
The autoflowering trait is what really opens this strain up. No messing about with light schedules, no worrying about light leaks triggering hermies, no separate veg and flower spaces. You plant the seed, give her light and nutrients, and she decides when to flower — typically within a few weeks of sprouting. For anyone who's been put off by the complexity of photoperiod growing, or who just wants a simpler run, this is a genuine game-changer.
Growing Blue Amnesia Autoflower Indoors and Outdoors
Blue Amnesia Autoflower is one of the more forgiving autos we've seen from Amsterdam Genetics. She doesn't demand expert-level attention, but a few things are worth knowing before you drop seeds.
- Germinate your seeds using the paper towel method or plant directly into a small pot of moist, lightly fertilised soil. Autos don't love transplanting, so starting in the final container (11–15L) saves stress.
- Provide 18–20 hours of light per day from seed to harvest. Unlike photoperiod strains, Blue Amnesia Auto doesn't need a 12/12 flip. Many growers run 20/4 for the entire cycle.
- Keep feeding light during the first 2–3 weeks. Autoflowers have a short vegetative window, so overfeeding early stunts growth you can't recover.
- Watch for the stretch. At 1.2–1.5m indoors, she's taller than many autos. If headroom is tight, consider low-stress training (LST) early — gently bending the main stem to open up the canopy.
- Outdoors, she can reach 2–3m in good conditions with direct sunlight. That's substantial for an auto and translates into yields up to 600g per plant.
- Harvest when trichomes shift from clear to milky-white with a few amber heads. A cheap jeweller's loupe (30x magnification) is all you need to check.
The honest limitation with any autoflower: you can't extend the vegetative phase if something goes wrong early. A nutrient lockout or pest issue in week two costs you more than it would with a photoperiod plant, because the clock is already ticking towards flower. Get your environment dialled in before germination and you'll avoid most headaches.
Flavour, Aroma, and the Blue Amnesia Experience
This is where Blue Amnesia Autoflower gets genuinely interesting. The flavour profile is a layered mix of sweet berry notes from the Blue Dream side and that sharp, spicy, almost incense-like haze character from the Amnesia parent. On the inhale, you get sweetness — think ripe blueberries with a sugary edge. The exhale is where the spice kicks in, peppery and herbal, lingering on the palate. It's a more complex smoke than most autoflowers manage.
The aroma during flowering follows the same pattern. Expect sweet, fruity terpenes with a haze undertone that gets stronger as the buds mature. Your carbon filter will earn its keep in the final weeks.
Compared to a standard Amnesia Haze auto, Blue Amnesia has noticeably more body to the effect — that 40% indica genetics from Blue Dream makes itself felt. If you've grown or smoked regular Amnesia and found it a bit racy or heady, the Blue Dream influence here smooths that out considerably. It's still sativa-forward, but with a physical anchor that keeps things grounded.
Blue Amnesia Autoflower vs Other Amnesia Strains
Amsterdam Genetics carries several Amnesia-lineage strains, so here's how Blue Amnesia Auto stacks up against the broader family:
| Feature | Blue Amnesia Autoflower | Typical Amnesia Haze (Photoperiod) | Standard Amnesia Auto |
|---|---|---|---|
| Genetics | Amnesia x Blue Dream | Pure Amnesia Haze | Amnesia x Ruderalis |
| Sativa / Indica | 60% / 40% | 80% / 20% | 70% / 30% |
| Flowering Type | Autoflowering | Photoperiod (12/12) | Autoflowering |
| Indoor Height | 1.2–1.5m | 1.5–2.0m+ | 0.8–1.2m |
| Indoor Yield | 450–550g/m² | 500–650g/m² | 350–450g/m² |
| Flavour | Sweet berry + spicy haze | Citrus + haze | Earthy + haze |
| Grow Difficulty | Beginner-friendly | Intermediate | Beginner-friendly |
The standout difference is yield. At 450–550g/m² indoors, Blue Amnesia Auto outperforms most autoflowers by a decent margin. One grower reported hitting 0.5 grams per watt — their highest yield from an auto — with dense, chunky buds matching the description. That's photoperiod territory for an auto, which is rare.
What Research Says About Amnesia-Lineage Cannabis
Amnesia Haze and its derivatives have been the subject of several analytical studies. According to Ferreiro-Vera et al. (2022), Amnesia Haze-type cultivars show distinctive sativa-dominant chemical profiles when analysed by Raman spectroscopy, confirming that the genetic lineage produces a consistent and identifiable cannabinoid-terpene fingerprint (PMC8948958). Separately, research charting the cannabis chemical space noted that Amnesia Haze is genetically comprised of approximately 80% C. sativa and 20% C. indica (PMC11127828). Blue Amnesia Autoflower shifts that ratio to 60/40 through the Blue Dream cross, which accounts for the more balanced effect profile.
Regarding cannabinoid effects more broadly, research into THC and CBD combinations suggests that CBD may modulate some of the subjective effects of THC, according to a study examining individual and combined effects of these cannabinoids (Englund et al., 2022). For growers interested in the therapeutic research angle, a review of phytocannabinoids noted that cannabinoid preparations have demonstrated potential in areas such as pain relief and sleep quality improvement in clinical settings (PMC11810933). These are research findings, not product claims — always consult a healthcare provider for medical questions.
Frequently Asked Questions
How long does Blue Amnesia Autoflower take from seed to harvest?
Expect roughly 10–12 weeks from germination to harvest. Autoflowers set their own schedule, so you won't be adjusting light cycles. She's reasonably quick for an auto that yields 450–550g/m².
Is Blue Amnesia Autoflower suitable for beginners?
Yes. The autoflowering trait removes the need to manage light schedules, which is the biggest hurdle for new growers. Start in your final pot, don't overfeed early, and she'll largely take care of herself.
Can Blue Amnesia Autoflower be grown outdoors?
Absolutely. Outdoors she can reach 2–3m and yield up to 600g per plant in good conditions with direct sunlight. She's not fussy about latitude since autoflowers don't depend on day length to trigger flowering.
What does Blue Amnesia Autoflower taste like?
Sweet blueberry on the inhale, spicy and herbal haze on the exhale. The Blue Dream parent brings the fruit, the Amnesia parent brings the pepper and incense. It's more complex than most autos manage.
How does Blue Amnesia Auto compare to regular Amnesia Haze?
Blue Amnesia Auto is more indica-influenced (40% vs 20%), shorter, and autoflowering. The effect has more physical weight. Standard Amnesia Haze is taller, higher-yielding, but requires photoperiod management and more grow experience.
Does Blue Amnesia Autoflower need a specific light schedule?
No. Most growers run 18/6 or 20/4 from seed to harvest. She'll flower regardless of light schedule, which is the whole point of autoflowering genetics. No 12/12 flip required.
What yield can I expect from Blue Amnesia Autoflower indoors?
Amsterdam Genetics lists 450–550g/m² indoors. Growers have reported hitting 0.5g per watt, which is strong for an autoflower. Good lighting, proper nutrition, and a stable environment are what separate the low end from the high end of that range.
