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.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Bisabolol underneath.

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.

Breeding Programme
Backcross Stabilisation (BX3) β€” clone-to-seed restoration
Stabilisation Notes β€” What This Means for Your Grow

Critical Kush has been the target of countless seed-bank backcross programmes. Ours is BX3 β€” 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 β€” pollen taken from a sibling male drawn from the same selected pheno population.
