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

Kryptonite — frequently asked questions

What is Kryptonite?

Kryptonite is a feminized 80% sativa by Pyramid Seeds, built on the Yumbolt genetics from the Sierra de Granada — with 20–23% THC, a 58-day flowering time under LED and an intense cerebral, psychedelic effect. One of the fastest-flowering sativas in the world.

Is Kryptonite indica or sativa?

Kryptonite is 80% sativa / 20% indica. The effect is predominantly cerebral and stimulating — euphoric, creative and psychedelic — with the small indica share adding a gentle physical relaxation.

Why does Kryptonite flower so fast for a sativa?

The Yumbolt genetics were specifically selected for short flowering times with the full sativa character. 58 days under LED is exceptional for an 80% sativa — typical sativas need 70–90 days. Kryptonite delivers the full haze effect in far less time.

What is the difference between Kryptonite and Kryptonite Fast?

Kryptonite Fast flowers even shorter — just 53 days under LED instead of 58. THC and yield are identical. Fast is ideal for several harvests a year or when maximum speed is the priority.
