Kryptonite Fast

Kryptonite Fast by Pyramid Seeds — the fast-flowering Fast version of Kryptonite, with a germination guarantee. 21–23% THC, 80% sativa from Yumbolt genetics: just 53 days flowering under LED — while fully preserving the signature sour-haze profile, potency and yield.

Key specifications

The Fast version: full power, shorter cycle

Kryptonite Fast is the fast-flowering selection of Kryptonite — the same Yumbolt sativa genetics from the Sierra de Granada, flowering 5 days shorter at 53 days under LED instead of 58. Identical potency, identical yield, identical sour-haze character. Ideal for growers who want more indoor harvests a year, or simply the fastest route to the full Kryptonite effect.

Aroma and terpene profile

Kryptonite Fast keeps the full aroma profile of the original — the signature sour haze-citrus profile of the Yumbolt line with an earthy pine depth.
