About Neptune Kush Feminised

Neptune Kush 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. pinene follows mid-palate, adding resinous clarity. The lab figure on this 10/90 sativa is 16% 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 Pinene, and Terpinolene underneath.

Difficulty: intermediate. In flower for 53 days (7-8 weeks). Stands 80-140 cm. Indoors it returns 550-600 g/m2. Outdoors, 600-650 g/plant a plant.
