Amnesia Auto is Growers Choice’s answer to a question Dutch growers have argued about for years: can the real coffeeshop Amnesia survive the jump to seed, let alone to an autoflower? The breeder spent around a year and a half working from the original Dutch clone, crossing Amnesia with Amnesia and nothing else, so no White Widow or other frosty “white” strain was brought in to stabilize it.
Many Amnesia seed lines on the market lean on White Widow for uniformity, and the result often smells and smokes more like a generic white strain than the clone. Here the goal was the opposite: keep the sour, acidic Amnesia personality and the familiar sativa-led high, then add ruderalis speed so the plant flowers on its own.
The outcome is a 30% Indica / 70% Sativa autoflower with 21–23% THC and a medium CBD rating. Plants stay manageable at 70–110 cm (28–43 in) indoors and 80–130 cm (31–51 in) outdoors, and Growers Choice lists indoor yields of 550–650 g/m² (1.80–2.13 oz/ft²).
Expect a total cycle of roughly 11 weeks from seed, no light-schedule switch and a sharp lemon aroma that announces itself well before harvest day.
Flavor and Effects of a True Dutch Amnesia
The breeder sums up the taste as sharp and sour lemon, and that is exactly how it lands. The first pull is bright and acidic, closer to lemon peel than lemon candy, with a clean, slightly peppery haze edge underneath. It tastes like biting into a lemon wedge in a cold Amsterdam canal-side bar: tart, crisp and wide awake.
In the jar the buds carry a punchy, sour-citrus nose with an earthy incense background typical of old-school Haze families. Three to four weeks of curing lets the zest come forward.
With 70% sativa in its makeup, Amnesia Auto is built for a heady, cerebral ride. The onset tends to be quick and climbs behind the eyes, bringing a talkative, energetic buzz with a strong focus on music, conversation or creative work. At 21–23% THC it is noticeably strong, so newer consumers should go slow.
The indica share keeps the body from feeling wired. Rather than a couch lock, the comedown is a gentle loosening of the shoulders that leaves the mind running. A daytime smoke for fans of clear, loud sativa.
Growing Amnesia Auto Indoors and Outdoors
Germinate straight into the final container (11–15 liters indoors) to avoid transplant stress, and run 18/6 or 20/4 light from day one through harvest. There is no switch to 12/12: the plant decides when to bloom, usually around week three or four.
Sativa autos stretch in early flower, so gentle low-stress training around weeks two to four is the most effective way to flatten the canopy and turn side branches into extra colas. Skip topping or keep it to a single early cut, because autos have little time to recover. Feed light in veg, then step up bloom nutrients.
Mold resistance is rated average, so keep humidity under 50% in late bloom and thin crowded inner foliage. Growers Choice recommends Amnesia Auto for medium-hot climates; outdoors it does well on a sunny balcony or patio, where plants finish at 80–130 cm (31–51 in) and can be run in several back-to-back crops between late spring and early fall.

FAQ
Is Amnesia Auto Indica or Sativa?
It is sativa-dominant: 70% Sativa and 30% Indica. The sativa side drives a cerebral, energetic high, while the indica share keeps the plant compact and the finish smooth.
What makes this Amnesia different from other Amnesia seeds?
Growers Choice bred it from the original Dutch Amnesia clone crossed back to Amnesia, without White Widow or other white strains. The aim is the authentic sour, acidic Amnesia flavor in an autoflowering plant.
How long does Amnesia Auto take from seed to harvest?
Plan on roughly 11 weeks from germination to harvest. Keep the lights on 18/6 or 20/4 for the whole cycle; no light switch is needed.
How much does Amnesia Auto yield?
Growers Choice lists indoor yields of 550–650 g/m² (1.80–2.13 oz/ft²) under good lighting, which is generous for a sativa-dominant autoflower.
How tall does Amnesia Auto grow?
Indoors it reaches 70–110 cm (28–43 in) and outdoors 80–130 cm (31–51 in), so it fits small tents, balconies and stealth spots.
Is Amnesia Auto easy to grow?
It is manageable for growers with a little experience. Mold resistance is average, so control late-flower humidity, and keep training gentle because autos have a short vegetative phase.
