About Critical Kush Auto

Will Critical Kush handle a South African summer outdoors? Yes. Put this 87/13 indica in the ground between September and November and you will be cutting from March to May. It stays low enough not to clear a boundary wall, and the short frame carries more weight than its size suggests. Bloom runs 70-80 days seed to harvest, placing harvest between March and May across most provinces.

What yield is realistic? 450-550 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, 180-250 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 21% THC with caryophyllene 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 indica genetics performs in either.

Does it cope with real summer heat? Reasonably. The dense foliage shades itself, so a spell above 28°C slows growth without stalling it. Mulch the root zone and water before 7am and heat stress stays manageable through most of the country.

When do I switch to bloom feed? As soon as pistils show, not a fortnight later. The 87/13 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 70-80 days seed to harvest environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full 180-250 g/plant. Difficulty: easy. In flower for 70-80 days seed to harvest. Stands 70-90 cm. Indoors it returns 450-550 g/m2. Outdoors, 180-250 g/plant a plant.

Aroma, Flavour and Effect

The first thing Critical Kush does at 21% THC is settle a warm peppery spice at the back of the throat. The euphoric, calm effects follow within minutes, starting as weight behind the eyes and working down through the shoulders and limbs. Fifteen minutes in there is a physical stillness — not sedation so much as a disinclination to get up. Two to three hours at a moderate dose. Myrcene sits underneath all of it, adding more body, reinforcing the physical side.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Bisabolol underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the bisabolol undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile bisabolol molecules are the first thing you lose.

Suitability and Recommendations

Who does well with Critical Kush? 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.

Critical Kush Auto — Breeder Information

Royal King Genetics

Recreated and stabilised by Royal King Genetics , the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.

Breeding Programme
Autoflower Stabilisation (F5) — ruderalis trait fixing
Stabilisation Notes — What This Means for Your Grow

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

Breeding Goal

Lock the autoflower trait in Critical Kush through five generations of selection.

Selection Focus

Chosen for resin density, indica-leaning frame and tight internodes that suit indoor production.

Pollen / Mother Source

Royal King Genetics select-mother programme — pollen drawn from an internally maintained reversed-female line.
