About Critical Sensi Star Feminised

Will Critical Sensi Star handle a South African summer outdoors? Yes. Put this 86/14 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 50-55 days, placing harvest between March and May across most provinces.

What yield is realistic? 500 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, +900 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% THC with myrcene 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 Myrcene, then Caryophyllene, and Linalool underneath.

Difficulty: medium. In flower for 50-55 days. Stands Medium. Indoors it returns 500 g/m2. Outdoors, +900 g/plant a plant.
