About Critical Kush Feminised

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 55-60 days, placing harvest between March and May across most provinces.

What yield is realistic? 550-650 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, 1000 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 55-60 days environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full 1000 g/plant. Difficulty: easy. In flower for 55-60 days. Stands 100-110 cm. Indoors it returns 550-650 g/m2. Outdoors, 1000 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. This trio turns up repeatedly in cultivars that win things, and it is why a jar of Critical Kush tends to get a reaction the first time it is opened after curing. Caryophyllene sets the anchor, myrcene fills the middle, and bisabolol sits in the background doing the work that separates this from every other strain built on the same primary terpene.

Suitability and Recommendations

Who does well with Critical Kush? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. 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.

Backcross Stabilisation (BX3) — clone-to-seed restoration
Stabilisation Notes — What This Means for Your Grow

Critical Kush has been the target of countless seed-bank backcross programmes. Ours is BX3 — three rounds of crossing the elite cut back to the parental line until trait expression evened out. The pack grows true to the mother cut.

Breeding Goal

Translate a clone-only modern hybrid cultivar to seed without losing the mother profile.

Selection Focus

Chosen for resin output, a low-slung stature and a clean indica terpene fingerprint.

Pollen / Mother Source

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