Our take

Knockout is a feminized, photoperiod sativa-dominant hybrid from Happy Valley Genetics, crossing XXX with End Game#3 to land at 27% THC. The flavor profile runs citrus and candy up front, grounded by pine, pepper, and earth. Growers at the beginner level will find the plant forgiving, and the dense buds reward patience without demanding expert technique.

Yields up to 530 g/m² indoors from feminized, photoperiod seeds — no male plants to sort out
Finishes flowering in roughly 63 days indoors, or by October for outdoor grows
Terpene trio of Caryophyllene, Terpinolene, and Limonene drives the citrus-pepper-candy aroma profile

Growing notes

Knockout fits a wide range of setups — indoors under controlled light, or outdoors in continental, Mediterranean, or reliably sunny climates. Plants reach a medium height, making indoor tent grows manageable. Expect dense, heavy buds by week nine of flower. Rated beginner-friendly, so first-time photoperiod growers should feel comfortable managing this one through its full cycle.
