About Blue Amnesia Auto

Will Blue Amnesia handle a South African summer outdoors? Yes. Put this 10/90 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 65 to 70 days, placing harvest between March and May across most provinces.

What yield is realistic? 100 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, 200 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% THC with pinene 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 10/90 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 65 to 70 days environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full 200 g/plant. Difficulty: easy. In flower for 65 to 70 days. Stands 100 cm. Indoors it returns 100 g/m2. Outdoors, 200 g/plant a plant.

Aroma, Flavour and Effect

The first thing Blue Amnesia does at 18% THC is arrive clean and resinous, like a pine plantation in the mist belt after rain. The relaxed, energetic, calm effects follow within minutes, as a sharpening rather than a lift: colour reads more saturated, music holds more detail, conversation wanders further than it would have. It runs two to three hours on a plateau instead of a peak, so nothing drops out from under you at the end. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.

The Aromatic Three

Leading with Pinene, then Limonene, and Caryophyllene underneath. How this combination survives the move from flower to vapour or smoke is not a given. Held low, at 180-188°C, the limonene and caryophyllene notes stay legible with pinene 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

Who does well with Blue Amnesia? People growing on flat balconies from Cape Town to Johannesburg. Smallholders after a fast outdoor crop. Indoor growers short on headroom. Autoflowering genetics run to their own clock, so there is no light schedule to hold, no worrying about light leaks, and harvest lands 10-12 weeks from germination whatever the season is doing. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.

Stabilisation Notes — What This Means for Your Grow

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

Breeding Goal

Reach auto trigger and finish-window uniformity for the Blue Amnesia pack.

Selection Focus

Chosen for clear-headed terpene expression, structural manageability and a finish that lands inside the published window.
