Alpha 21

Alpha 21 is a feminized photoperiod Sativa-dominant hybrid from AlphaFem Seeds, bred from Totally Alpha OG crossed with Haze IBL and the Afghani landrace Zalla. Despite the Sativa genetics, it grows compact — typically no taller than 120cm — making it deceptively easy to manage indoors. THC hits 30% and the effects are firmly body-focused: heavy full-body relaxation, sedation, and mood elevation that makes it a strong candidate for chronic pain, insomnia, and anxiety relief. Don't expect a racy cerebral Sativa high.

Flowering time is notably fast for a high-THC strain: 7–9 weeks from the flip to 12/12. Indoor yields can reach up to 600g/m² under optimised conditions — a genuinely high-producing plant. Outdoor plants can yield 600–800g each in a warm, sunny climate. The terpene profile features caryophyllene, limonene, and myrcene, giving a spicy-woody aroma with sweet citrus undertones. ScrOG training and trellising for heavy colas are recommended. Adequate ventilation is important given the dense bud structure. Suitable for growers of all levels who want a compact, fast, high-yield medical strain.
