42 Fast Buds – AK Auto
Old-school AK-47 genetics as a fast autoflower
AK Auto by 42 Fast Buds brings one of the most legendary cannabis genetics of all time into a modern autoflower version. The variety is based on the famous AK-47 line, which originally emerged from a combination of Colombian, Mexican, Thai, and Afghan landraces and has been one of the most well-known hybrid strains worldwide since the 1990s.
For the autoflower variant, this classic genetic was combined with the breeder's stable autoflower genetics. The result is a robust plant with a fast life cycle, high resistance, and the characteristic old-school AK aroma.
With up to approximately 21% THC, AK Auto delivers a powerful sativa-dominant effect. At the same time, it is considered particularly easy to cultivate, which is why it often ranks among the most popular autoflower strains for beginners.
The plants grow relatively uniformly and develop long, dense colas along the branches. Under optimal conditions, approx. 400–500 g/m² indoors are possible, while outdoor grows can yield 50–170 g per plant.
Also typical for this genetic is the classic terpene profile: when breaking open the buds, an intense fragrance of lemon, pine, and spicy forest notes unfolds, which reminds many growers of classic old-school cannabis varieties.
The complete life cycle is about 9 weeks from seed to harvest, which makes multiple grow runs per year possible.
