About Sour Amnesia Auto

Will Sour Amnesia handle a South African summer outdoors? Yes. Put this 20/80 sativa in the ground between September and November and you will be cutting from March to May. It will stretch, and it will use every hour of a long summer day, so give it room early rather than trying to contain it later. Bloom runs 50-60 days, placing harvest between March and May across most provinces.

What yield is realistic? up to 350 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 350 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 20% THC with limonene in front, the return on effort is good.

How much can go wrong before it shows? Some. Anyone who understands pH, a feeding schedule and a light cycle will be fine. Neglect it entirely and it will suffer, but a single missed watering will not undo the grow.

Further Questions from South African Growers

Which medium suits it best? Depends what you are optimising for. Organic soil cut with 30% perlite and amended with bone meal, rock phosphate and kelp meal gives the fuller flavour, and all three are stocked by garden centres, agricultural co-ops and hydro shops countrywide. Coco under automated fertigation at EC 1.4-1.8 through bloom gives the bigger number. This sativa genetics performs in either.

Does it cope with real summer heat? Better than most things you could plant. An open canopy sheds heat on its own. Past 38°C you may see midday wilt, but it recovers within the hour once temperatures fall — 30% shade cloth takes the edge off the UV without costing you growth.

When do I switch to bloom feed? As soon as pistils show, not a fortnight later. The 20/80 genetics changes its demand sharply at the transition: phosphorus and potassium uptake rises while nitrogen demand falls away. Soil growers can top-dress with guano and sulphate of potash; coco and hydro growers should move to a low-N, high-PK formula immediately.

Indoors or outdoors? Indoors buys control over the 50-60 days environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full up to 350 g/plant. Difficulty: easy. In flower for 50-60 days. Stands Medium. Indoors it returns up to 350 g/m2. Outdoors, up to 350 g/plant a plant.

What Sour Amnesia Is Like to Use

The effects most commonly reported for this cultivar are euphoric, relaxed, uplifted. At 20% THC it sits in a bracket where there is a usable working range. Vaporised between 175°C and 185°C it lifts mood and mental energy in a way that suits creative work, a hike, or a long afternoon around a braai. The body stays light, so for anyone with a THC tolerance it holds up as a daytime option. The Limonene/Terpinolene pairing leaves a zesty, clean aftertaste on the palate.

Where it fits: creative work, company, being outdoors, and unstructured daytime hours.

The Aromatic Three

Leading with Limonene, then Terpinolene, and Pinene underneath. How this combination survives the move from flower to vapour or smoke is not a given. Held low, at 180-188°C, the terpinolene and pinene notes stay legible with limonene underneath them. Run it hotter, or burn it, and the three collapse into one — still pleasant, but without the separation that makes this cultivar worth paying attention to.

Suitability and Recommendations

Sour Amnesia is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Because it autoflowers there is no light cycle to manage at all, which is what makes it work on a balcony, in an out-of-the-way outdoor spot, or anywhere a timer would be one more thing to go wrong. A September-to-May outdoor season comfortably covers a 50-60 days bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.
