Description
Born from the cross of XXX and End Game #3, Knockout is a sativa-dominant photoperiod variety from Happy Valley Genetics that carries a vivid aromatic profile, fruity on the nose with a clean piney backbone that carries through to the finish. Effects sit firmly in uplifting territory, the kind of clear, motivating experience that suits a daytime occasion. THC expression is very high, consistently pushing above 25%, so this is a strain that rewards patience and proper curing.
Knockout feminised seeds are well suited to indoor cultivation, where growers can expect a high yield in the range of 450-600 g/m2 over an 8 to 10 week flowering window. A medium height plant keeps canopy management straightforward, making it a practical choice for tent growers who want serious output without excessive vertical pressure. The all-female seed stock eliminates the guesswork of sexing, letting you focus on dialing in your environment. For cultivators chasing a high-THC sativa with real flavor and dependable structure, Knockout is a strain worth building a run around.

about this product
Knockout by Happy Valley Genetics brings sativa-dominant potency and a bright fruity-piney profile together, ready for intermediate growers who want a rewarding, high-yielding photoperiod strain.
Knockout delivers a clear, uplifting head experience that sits firmly in daytime territory — motivating rather than sedating. THC consistently pushes above 25%, so the effect is powerful and best appreciated by those already comfortable with high-potency sativas.
The aromatic profile opens with bright, fruity notes and settles into a clean piney backbone that carries right through to the finish. It's a vivid, well-defined combination that makes the curing stage genuinely worth the patience.
Knockout is rated easy to moderate, making it accessible to growers who have at least a basic grow or two under their belt rather than absolute beginners. Its feminised format removes the need to sex plants, which simplifies the process considerably.
Indoor growers can expect a high yield in the 450–600 g/m² range, with a flowering window of 8 to 10 weeks. Dialling in your environment and allowing a proper cure will make the most of both the yield and the potency.
