Sour Diesel Auto offers a modern, autoflowering twist to classic Sour Diesel.

Sour Diesel Auto by Seedsman captures the unmistakable character of classic Sour Diesel in a faster, more modern autoflowering format. Bred from California Sour Diesel, Headband Auto, and HumboldtSour Diesel, this sativa-dominant strain delivers everything that made Sour D famous - sharp sour fuel terps, elongated lime-green buds, vigorous growth, and an uplifting cerebral effect - while adding the speed, reliability, and convenience of autoflower genetics. The result is a high-THC auto that stays true to its roots while offering a more accessible route into one of cannabis’s most iconic flavour and effect profiles.

With a 55-65 day lifecycle, Sour Diesel Auto is suitable for all growing environments and offers strong performance both indoors and out, producing up to 600 g/m2 indoors and 200-450 g per plant outdoors. Its buds are long, lime green, and thick with resin, giving the plant the same visual appeal that Sour Diesel fans expect from the original. The aroma is unmistakably classic, led by sour fuel notes with the bright, punchy character that defines the Diesel family, while the effect is energetic, euphoric, and clear-headed. For growers looking for a modern autoflower that expresses the full spirit of Sour Diesel without losing its legendary edge, Seedsman Sour Diesel Auto is a standout choice.

This was the fastest flowering plant of my whole grow. It was flowering in week 3. It’s now week week 5 of full flower mode and it looks awesome. I would recommend this strain from Seedsman for anyone looney to growing and want to mad it easy.

This strain is amazing. High concentration of THC, dependable results. Not a large plant though. Thinking I won't do auto flower next year.

4 of six Auto seeds came up. Seems to be very good upon a rushed sample. Makeshift box to slow drying time to approx 12 days if the air in here is not too dry. Indoor light grow on 24/7 light. Next time in will be 20/4 off. Yeild is smaller than I thought. Very pleased overall. First indoor grow in almost 30 years for me. Will be doing it again. Better each time.

This is the BEST strain ever. All my friends clamor to share it. But, my new babies are 8" tall and BUDDING. I'm devastated! Will reorder and hope to have a good crop before fall.

Frequently asked questions
Is this strain suitable for my growing environment?

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.

How difficult is this strain to grow?

Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.

What can I expect in terms of cannabinoid content and yield?

Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.

Is this strain suitable for beginners?

Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
