About Amnesia Auto
Cured properly and opened cold, Amnesia leads with terpinolene: a restless herbal note of rosemary and cold apple skin, with a thread of something floral that moves as you breathe in. Underneath it limonene adds a bright edge that keeps the nose from turning heavy, and it reads mid-palate rather than on the first pass. This 16/84 sativa tests at 20% THC, but potency is the least interesting number here: what separates Amnesia from the others on the same shelf is how the aroma behaves across a cure, and that is a question of storage and patience rather than genetics alone.
Growing it for the nose rather than the scales
Chasing terpene expression in Amnesia pulls against chasing yield, and it is worth knowing which one you are doing before you start. The Terpinolene/Limonene/Ocimene profile does its best work in living soil, where the microbial side produces secondary compounds a bottle cannot. That is easier here than it sounds: decent peat-free compost and worm castings are a garden centre purchase in most British towns.
Through the 60 days of bloom, stop foliar spraying after week two — anything landing on developing trichomes is still there at harvest and you will taste it. The final three weeks decide which terpenes dominate the cured flower: nights held at 16-18°C push terpinolene forward, while a warmer finish protects the lighter ocimene notes at the top.
The cure is where most of the flavour is lost in this country, and the reason is the weather. A 10-14 day hang wants 15-18°C at 55-60% relative humidity, which a British autumn will not give you in a spare room — a temperature-controlled cupboard or a wine fridge set to 16°C solves it for the price of one wasted harvest. Then into glass, burped twice a day for the first fortnight. The limonene layer that makes this one worth growing does not appear until somewhere between weeks three and four in the jar.
Flowering: 60 days. Indoor yield: 550-600 g/m2. Outdoor yield: 120-200 g/plant. Plant height: 150 cm. Rated intermediate difficulty.
What Amnesia is actually like
Growers report creative, sleepy, focused, energetic as the defining characteristics and our own notes agree. At 20% THC this sativa sits where most people find a workable window. Vaporised at 175-185°C the first effect is lift and mental energy, suited to work that benefits from it, a long walk, or an afternoon with company. The body stays light throughout, which makes it a genuine daytime option for anyone with a tolerance. The Terpinolene/Limonene pairing leaves a finish that keeps changing across a session.
Best suited to creative work, company, getting outdoors, and daytime use generally.
Terpene breakdown
Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with terpinolene; after three or four weeks sealed in glass at 16-18°C the ocimene underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter ocimene molecules are the first thing heat destroys.
Who it suits
Amnesia suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Autoflowering genetics take the light cycle out of the equation, which suits balcony growers, anyone working around British daylight hours, and anyone who wants the whole thing over quickly. The April to October season accommodates a bloom of 60 days comfortably for outdoor growers across the country.

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.
Lock the autoflower trait in Amnesia through five generations of selection.
Chosen for vigour, manageable stretch and the cerebral terpene profile sativa growers buy this strain for.
