What is the Kryptonite Fast version?

Kryptonite Fast is the fast-flowering version of Kryptonite — Yumbolt sativa genetics with 21–23% THC and just 53 days flowering under LED. The same potency, the same sour-haze profile, a shorter cycle than the original.

What is the difference between the Fast version and an autoflower?

Kryptonite Fast is photoperiod — it needs the switch to 12/12 to flower, giving full control over the veg phase. Auto Kryptonite flowers automatically with no light schedule — simpler, but less control over the veg phase.

Does Kryptonite Fast have the same terpene profile as Kryptonite Fem?
