About C4 Feminised

C4 announces itself in a fixed order, and limonene is always first out of the jar β€” a citrus lift that arrives before the lid is fully off, lemon rind and tangerine with a sweetness trailing it. caryophyllene follows mid-palate, adding a grounding spice. The lab figure on this 50/50 hybrid is 20% THC, though potency is the least interesting thing about it β€” plenty of cultivars test the same and taste of very little.

The Aromatic Three

Leading with Limonene, then Caryophyllene, and Linalool underneath.

Difficulty: beginner to intermediate. In flower for 55-65 days. Stands 90-120 cm. Medium. Indoors it returns up to 400 g/m2. Outdoors, up to 500 g/plant a plant.
