Genetics: Yumbolt from the Sierra de Granada
Kryptonite is built on the Yumbolt line — a legendary sativa genetic selected and stabilised by breeders in the Sierra de Granada. Yumbolt is known for its distinctive sour-haze profile, a fast flowering time despite sativa dominance, and an intense cerebral effect.
What sets Kryptonite apart from other sativas: a 58-day flowering time under LED — exceptionally short for an 80% sativa. Typical sativas need 70–90 days. Kryptonite delivers the full sativa character in far less time — with no compromise on potency or aroma.
Effects
80% sativa — the effect is cerebral and stimulating to match:
- Cerebral kick — intense mental stimulation, clear thoughts
- Euphoria — a lifted mood, energy and joy
- Psychedelic character — a deep, layered experience
- Creative boost — ideal for creative work and social moments
- Physical relaxation — the 20% indica share rounds the effect off gently
Aroma and terpene profile
The signature trait of Kryptonite: sour haze notes that gain a special depth through the Yumbolt cross — rounded out by citrus, fresh pine and spicy earth.
| Terpene | Typical impressions | Contribution to the profile |
|---|
| Limonene | Fresh, citrusy, sour | The main carrier of the haze sourness — mood-lift, euphoria |
| Caryophyllene | Spicy, peppery | Gives the sativa profile a spicy depth |
| Pinene | Fresh, pine-like, needle | The fresh pine component — promotes alertness |
| Myrcene | Earthy, slightly fruity | Earthy base — links sativa freshness with depth |
