説明

She can be grown indoors or outdoors and withstand all environments thanks to her pedigree genetics. AK Auto is a strain that is very easy to grow, that makes it perfect for beginners. She packs a punch with a THC level of up to 21%. She will grow long dense colas in just 9 weeks with citrus pine flavored buds. Despite her Sativa influence, this girl is a foolproof hybrid for those who need a solid producer with a quick turnaround time, as well as commercial growers. 

Auto AK is a sativa-leaning autoflower developed from AK47 crossed with Fast Buds Auto #1, refined into a stable F4 feminized line. This pairing was selected to preserve the classic AK structure and energetic character while improving resin production, uniformity, and autoflower reliability.

Plants grow 80-100 cm with a homogeneous structure that allows close spacing and efficient canopy use. Flowers form elongated, tightly stacked buds with a silver-frosted appearance and strong trichome coverage extending into the surrounding leaf. Indoor yields reach 400-500 g/m², with outdoor plants producing up to 170 g per plant under suitable conditions.

Flavors are old-school and grounded, combining earthy, floral, pine, and light citrus notes. With THC levels up to 21% and consistent resin output across buds and trim, Original Auto AK performs well for extraction, delivering clean, aromatic concentrates with dependable returns.

Original Auto AK is a solid choice for growers and processors seeking classic AK genetics, fast turnaround, and reliable resin production in a compact, resilient autoflower suited for both flower harvests and concentrate work.

I enjoyed growing out and nice smoke!
She was easy to grow, not that big but I broke a few roots during transplant and stunted her. Super dense buds, vigorous feeder too. On the list to grow again for sure!

It grew kinda short
Maybe I should've done some LST or something, but it grew shorter than I expected. The buds have turned out great, but would've liked more height.
