About Jack Skellington Feminised

Jack Skellington announces itself in a fixed order, and terpinolene is always first out of the jar β€” a herbal bouquet that resists being placed, part rosemary and part crisp apple, with a floral edge that shifts the longer you breathe it in. limonene follows mid-palate, adding a bright citrus edge. The lab figure on this 25/75 sativa is 15% 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 Terpinolene, then Limonene, and Ocimene underneath.

Difficulty: medium. In flower for 8 weeks. Stands Tall. Indoors it returns 350 gr/mΒ². Outdoors, 400 grams a plant.
