Hawaiian Sativa Cannabis Seeds Feminized
Hawaiian Sativa is a feminized, mostly Sativa hybrid from the Quebec Cannabis Seeds team, bred from long-kept Federation Seed genetics crossed with a QCS Grapefruit male. It tests at about 21% THC (typically 19–22%) with around 1% CBD, flowers in 65–70 days, and yields up to ~500 g/m² indoors or up to ~600 g per plant outdoors, where it is ready from mid-October. It is relatively easy to grow and suits indoor, greenhouse, and hydroponic setups, or outdoor gardens where the season runs late into October. Reported effects are energetic and uplifting, with a bright grapefruit and tropical fruit flavor.
Genetics: Federation Seed Genetics × QCS Grapefruit
Federation Seed genetics — a Hawaiian Sativa line kept for roughly 20 years — provide the classic, old-school Hawaiian character and the energetic Sativa effect.
QCS Grapefruit contributes the sweet citrus and fruit notes that define the flavor.
