Description

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.

Endlich mal wieder eine starke Sativa
Schon lange such ich nach schönen Sativa Strains die einen Energie und Stimmung schenken. AK Auto und Mexican Airlines Auto sind definitiv solche und haben mir wieder die Freude zum Joints zurück gegeben, davor war nur noch growen und wenig rauchen angesagt, jetzt kann man sich durch die 2 Experten wieder beidem mit voller Leidenschaft hingeben. Bleibt gesund und High euer Mediziner

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!

Customer questions & answers

Beginner here… I started my plant outside. I noticed the plant is getting tall, almost like stretching. Like 2 - 3” between nodes…. Will it hurt to move inside to a tent and how high do i set the lamp
Hello, thanks for asking. It won't hurt it but make sure you provide enough light to avoid stressing your plant. The distance depends on the light fixture, please send an email to [email protected] and we'll guide you.
my plant produces seeds, whats wrong? can i use these seeds?
Hello. You can definitely use the seeds but you should identify why your plant is producing seeds. Are there any male plants around?
Any articles on mainlining,energy pathways,etc?
Hello, thanks for asking. We have a couple of blogs about plant training techniques, you can check them here: 2fast4buds.com/news
Can I switch lighting from 18/6 to 24 when in the flowering stage? will this increase my bud production?
Thanks for asking. Yes you can and it can improve yields, just make sure you feed your plants properly and maintain good conditions.
What’s the ideal curing time?
Hello, thanks for asking. The ideal curing time would be a minimum of 15 days.
I'm about to harvest my beautiful AK. What's the best way to dry it?
Hello, thanks for your question! You should dry your buds in a dark room with a relative humidity of around 50% and a temperature of around 18-23.
How can I make my buds denser?
Hello! To fatten up your buds it's essential you grow under the proper wattage for the number of plants you have and make sure you provide good-quality blooming nutrients. Remember that plants need more phosphorus and potassium when they're flowering.
I accidently let the trichomes go about 30% amber. I have heard that that's too much. What will happen to the quality of the flowers?
Hello! The quality will be the same but the effect may be more corporal due to the THC degrading into CBN.
I tried doing some LST but she grew funny. Not sure what happened.
Hello, thanks for your question! We only recommend performing LST after you've gathered a bit of information, even though LST doesn't stress your plants as much as HST, doing it aggressively will stress your plants and they can end up growing shorter and producing less than they should.
What's the difference between SOG and SCROG?
Hi, thanks for your question! Both of them consist of spreading the canopy to fill your trellis net evenly but in SOG you do it with a lot of smaller plants while in SCROG you should do it with less plants while letting them grow taller.
Its' been really hot and some of my leaves have started to get brown patches on them. Should I remove these leaves?
Hello! It's not necessary to remove the leaves because they will fall by themselves but you can remove them if you want to.
What's the best light schedule to use with this strain?
Hi! It depends on what suits you better, you can grow it under an 18/6, 20/4, or 24/0 light cycle. Have in mind that more light results in better yields but your electricity bill will be higher.
My Auto AK is quite foxtailed. What causes this?
Hello! Foxtailing is usually caused by excessive heat but it's also a characteristic that some genetics have.
