Description

Alpha 21 Strain Info

The breeder of this strain, who's come a long way from humble trimmer to the founder of his own seedbank, created this Sativa-dominant marvel with ease of cultivation and product potency in mind. The legendary OG family serves as the backbone of this strain, which explains Alpha 21’s exceptional therapeutic potential and huge demand in the medical community.

Genetics

Alpha 21 is a hybrid resulting from crossing the flagship Totally Alpha OG with a pure Sativa line of Haze IBL, complemented by the addition of the Afghani landrace Zalla. The result is a plant whose clear Sativa dominance isn’t obvious in either its compact size or short flowering time, nor in its body-focused effects.

Flowering Time

The flowering time of Alpha 21 can be as short as 49 days (7 weeks) of 12/12 and rarely takes more than 63 days, so growers looking for fast-finishing cultivars can definitely find a phenotype of a record-breaking speed here.

Yields

Despite some variance in maturation times, the strain consistently produces up to 600 g/m² (2 oz/ft²) in indoor setups. Outdoors, yields depend on climate conditions as much as the love and care you’re willing to provide and may reach 600-800 g (1.3-1.76 lb) per plant.

Effects

Expect a potent full-body relaxation that will take care of anything that might have bothered you before, be it an aching body or nagging anxieties after a busy and stressful day. Alpha 21 is the perfect way to purge all that, stop caring about anything, and eventually fall asleep.

Medical Properties

The symptom relief generously offered by Alpha 21 includes all the usual suspects like stress, insomnia, anxiety, and of course, pain of any origin.

THC and CBD Levels

Alpha 21 is among the most potent strains bred by AlphaFem Seeds, as its THC content can go as high as 30%, with CBD levels clocking in at under 2%. This intimidating cannabinoid composition is one for long-time habitual smokers, while newbies should tread lightly and have no more than one shallow toke before venturing further.

Smell and Taste

Alpha 21's terpene profile offers spicy and woody notes of caryophyllene in its aroma, complemented by a pleasant sweetness upon the exhale, with delightful hints of citrus and earthiness from limonene and myrcene.

Good to Know

Despite the strong Sativa influence, these plants don’t grow taller than 120 cm (4 ft), which is a very convenient feature for limited spaces. However, even in this case, we recommend using ScrOG to train Alpha 21 so that its yields can reach their full potential.

  • Implement training to keep every top at the same distance from the light source.
  • Use trellising to provide support for heavy colas.
  • Ensure adequate ventilation to mitigate the risk of mold.

    • Advantages
      I've grown Alpha 21 outdoors and the results have been incredible: easily over 700g per plant, with some even exceeding 800g. It thrives in warm climates, but even in cooler conditions, it has performed well with proper care.

      The high is absolutely overwhelming
