Moby Dick Auto Seeds – Seed Stockers · XXL Yield & 26% THC Sativa

Moby Dick Auto by Seed Stockers is a monstrous Sativa-dominant autoflowering strain that guarantees XXL harvests and mind-bending potency in record time. By combining the legendary genetics of White Widow and Haze Auto, this powerhouse delivers up to 26% THC and an uplifting, psychedelic high without the endless wait of traditional Sativas.

Are you tired of sacrificing yield and potency just to get a fast autoflowering harvest? Many growers struggle to find a quick-finishing strain that actually produces the heavy, resin-soaked colas typical of a photoperiod Sativa.

• Keep temperatures around 22–25 °C.
• Use a light, airy soil mix with 30% perlite.
• To accelerate rooting, X-Seed Organic Vegan Seed Germinator by BAC is fantastic.
• Do not transplant; autos hate root stress.

Vigorous Veg: Provide 18 to 20 hours of light daily and water sparingly to encourage root expansion.

• Avoid aggressive pruning like topping or FIMming.
• Use gentle LST to open the canopy.

Frequently Asked Questions

How big does Moby Dick Auto get?

Under optimal indoor conditions, it usually reaches between 0.80 and 1.10 m (2.62 and 3.61 ft). Outdoors in a sunny Mediterranean climate, it can stretch up to 1.30 m (4.27 ft). It's a vigorous plant, so make sure your grow tent has enough vertical space.

Can I top or prune this autoflower?

It is highly recommended to avoid high-stress training like topping or FIMming. Because it has a strict 77-day life cycle, it doesn't have time to recover from severe stress. Instead, use Low Stress Training (LST) by gently tying down the branches to improve light penetration.

Is the effect too strong for beginners?

With THC levels pushing 26%, the effect is incredibly potent and psychedelic. If you have a low tolerance, it's best to take it slow. However, the high is very uplifting and productive, making it a great daytime smoke if consumed in moderation.

Does it smell a lot during flowering?

Yes, the White Widow and Haze genetics produce a strong, sweet, and citrusy aroma during the late flowering stage. A good quality carbon filter is essential if you are growing indoors and need to keep things discreet.

Personal Experience of Pevgrow’s CEO (Alan)

Whenever I want a stash jar full of uplifting, daytime motivation without waiting half the year, Moby Dick Auto is one of my top picks. I usually run these in 20-liter fabric pots under a 20/4 light cycle, and the sheer vigor they show in the first month always blows my mind. You can literally see the Haze genetics stretching for the light, but it stays manageable enough for a standard 1.20 m (3.94 ft) tent.

What I love most about this Seed Stockers version is how they managed to keep that classic, mouth-watering vanilla and eucalyptus flavor intact. Vaping this strain at around 180 °C is an absolute treat for the palate. It hits you fast right behind the eyes, clearing the brain fog and getting you ready to tackle creative projects or just enjoy a sunny weekend outdoors.

My biggest piece of advice with this beast is to keep your humidity in check during the final three weeks. The colas get incredibly thick and dense—thanks to the White Widow lineage—so good airflow is non-negotiable to avoid botrytis. Treat her right, and she will reward you with some of the heaviest auto yields you've ever seen.
