About Amnesia Auto

Open a jar of properly cured Amnesia and the first impression is unmistakably terpinolene — a complex herbal bouquet — part fresh rosemary, part ripe apple, with a floral note that shifts as you inhale deeper. Beneath this primary note, limonene introduces a bright citrus lift that emerges mid-palate. This 16/84 sativa tests at 20% THC, but the sensory journey is what distinguishes Amnesia from other cultivars at comparable potency. Think of it like comparing a single-origin wine to a blended table variety — the numbers might overlap, but the experience diverges sharply.

Developing the Full Flavour Profile

Growing Amnesia for maximum terpene expression requires deliberate choices that differ from growing purely for yield. The Terpinolene/Limonene/Ocimene profile responds particularly well to organic living soil — the microbial activity in a well-established no-till bed creates secondary metabolites that synthetic nutrients simply cannot replicate. UK growers have access to excellent local compost and worm casting suppliers that make this approach practical.

During the 60 days period, avoid foliar sprays after week 2 — anything deposited on developing trichomes compromises the aromatic purity at harvest. Temperature manipulation in the final three weeks profoundly influences which terpenes dominate the cured flower: cooler night temperatures (16-18°C) amplify terpinolene expression, whilst warmer finishes preserve the lighter ocimene top notes.

The cure is where most UK growers leave flavour on the table. After a 10-14 day hang dry at 15-18°C and 55-60% relative humidity (a challenge in a damp British autumn — a climate-controlled room or wine fridge set to 16°C works brilliantly), transfer to glass jars and burp twice daily for the first fortnight. The limonene secondary notes that make this strain genuinely special only emerge after 21-28 days of jar curing. Patience transforms a good flower into a remarkable one.

Flowering: 60 days. Indoor yield: 550-600 g/m2. Outdoor yield: 120-200 g/plant. Plant height: 150 cm. Rated intermediate difficulty.

What to Expect When Using Amnesia

UK customers report creative, sleepy, focused, energetic as the defining characteristics, and our experience aligns with that consensus. At 20% THC, this sativa sits in a potency bracket where most users find a productive sweet spot. Vaporised at 175-185°C, the initial effect is a noticeable uplift in mood and mental energy that pairs well with creative projects, long walks, or an afternoon with friends. The body remains light and mobile throughout, making this a genuine daytime option for those with THC tolerance. The Terpinolene/Limonene terpene combination imparts a flavour that lingers on the palate — complex and shifting, revealing new notes across the session.

Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.

Terpene Breakdown

Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. Together these three compounds construct an aromatic signature that evolves throughout the curing process. Freshly dried flower leads with terpinolene presence, but after three to four weeks in sealed glass jars at 16-18°C, the ocimene undertone strengthens and the overall bouquet develops a layered complexity. Vaporisation between 180°C and 195°C captures the broadest spectrum of these terpenes — higher temperatures degrade the more volatile ocimene molecules first.

Suitability and Recommendations

Amnesia suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar — it will not hold your hand, but it will not punish minor mistakes harshly either. Autoflowering genetics eliminate the need for light cycle manipulation, making this ideal for UK balcony growers, guerrilla setups, and anyone wanting a fast turnaround from seed to harvest. The UK growing season (April through October) accommodates the 60 days bloom period comfortably for outdoor cultivators across the country. Shipped discreetly across the UK with our germination guarantee.

Stabilisation Notes — What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Amnesia sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Lock the autoflower trait in Amnesia through five generations of selection.

Selection Focus

Chosen for vigour, manageable stretch and the cerebral terpene profile sativa growers buy this strain for.

Pollen / Mother Source

Royal King Genetics in-house mother stock — pollen taken from a sibling male drawn from the same selected pheno population.
