Moby Dick Auto by Silent Seeds – High-Yielding Sativa-Dominant Autoflower with Citrus-Pine Aroma

Moby Dick Auto by Silent Seeds is a premium sativa-dominant autoflowering cannabis strain that redefines what’s possible in automatic cultivation, delivering record-breaking yields, a complex citrus-pine aroma, and a powerful, balanced high in just 70–80 days from seed to harvest.

Are you tired of underperforming autoflowers with weak effects and bland flavors?

Most autoflowering strains leave you settling for small harvests, inconsistent potency, or dull, one-dimensional tastes. You invest time and effort only to end up with flowers that lack character, resin, or real punch—especially when you're chasing that legendary Haze experience.

It’s frustrating to see your grow space underutilized, your expectations unmet, and your sessions falling flat. The truth is, many autos just can’t deliver the premium quality you’d expect from a true connoisseur strain—leaving you stuck in a cycle of compromise.

Moby Dick Auto changes everything. Born from the legendary White Widow Auto and Haze 2.0 Auto, this elite hybrid brings the power, aroma, and yield of a photoperiod champion—without the wait. It grows fast, tall, and resinous, flooding your space with a rich bouquet of citrus, pine, and incense, while delivering a long-lasting, euphoric yet grounded high. This isn’t just another auto—it’s the new gold standard.

Before growing Moby Dick Auto

Without this strain, your grow might rely on outdated genetics that demand perfect conditions, stretch uncontrollably, or collapse under humidity. You’re likely juggling multiple plants to make up for low yields, or stuck with short-flowering but forgettable strains that don’t inspire.

• Choose a spacious pot early—18–27 L (2–3 gal) helps maximize its vigorous growth
• Mix in 30% coco coir to improve root aeration and drainage
• Start with a light, well-draining soil like Light Mix BioBizz for optimal seedling development
• Ensure 18–20 hours of light daily from day one
• Keep humidity at 60–70% in early stages to prevent stress

During cultivation: watch it thrive

Moby Dick Auto explodes out of the gate with rapid vertical growth, often reaching over 1.40 m (4.59 ft) even outdoors. Its sativa structure shows early, with long internodes and a Christmas tree-like branching pattern that’s perfect for light penetration.

Unlike typical compact autos, this plant demands space—but rewards you with massive colas covered in glistening trichomes. From week 4, you’ll notice the aroma intensifying: sharp citrus up front, deepening into woody pine and spicy incense as flowering kicks in.

Monitor humidity closely—ideally dropping to 40–50% in mid to late flowering to protect those dense buds. A simple HESI Root Complex addition can boost root resilience, especially in coco or hydro setups.

After harvest: quality you can feel

Once dried and cured, Moby Dick Auto reveals its full potential: long, spongy buds coated in resin, with a flavor profile that’s both refreshing and deeply complex. Indoors, you can expect up to 500 g/m² (17.6 oz/ft²), while outdoor plants regularly hit 110–250 g/plant (3.88–8.82 oz/plant), depending on sun exposure.

Maintenance is minimal—just clean your tools and store seeds in a cool, dark place. The real reward? A high-octane, clear-headed euphoria that gradually relaxes the body, perfect for creative afternoons or social evenings.

Safe start

Launch your grow with strong germination and early root development.

• Germinate seeds at 22–25 °C (71.6–77 °F) with high humidity
• Transplant when the taproot is ~1 cm (0.39 in) long
• Use a light, airy medium like Light Mix BioBizz to prevent compaction
• Water lightly—just enough to keep the medium moist
• Add HESI Root Complex to boost early root growth and resilience

Directed growth

Guide your plant through vigorous veg with smart support and feeding.

• Provide 18–20 hours of light daily—no schedule changes needed
• Use 18–27 L (2–3 gal) pots to accommodate its tall structure
• Apply gentle LST to spread branches and improve light access
• Feed with mild nutrients—avoid overfeeding, especially in coco
• Ensure good airflow to manage its strong, pungent aroma

Efficient flowering

Optimize bud development and resin production in the final stretch.

• Lower humidity to 40–50% to protect dense flowers
• Support heavy colas with soft ties or a trellis if needed
• Use bloom boosters like Bud Fuel Pro in mid-flower for extra density
• Flush 7–10 days before harvest to improve taste and smoothness
• Monitor trichomes: harvest when mostly milky with some amber for balanced effect

Frequently Asked Questions

How long does Moby Dick Auto take to harvest?

From seed to harvest, Moby Dick Auto takes 70–80 days, regardless of light schedule. Outdoor harvests typically fall between late June and late October, depending on climate.

Is Moby Dick Auto good for beginners?

Yes, it’s beginner-friendly in terms of resilience and ease of care, but its height and strong smell mean it’s best suited for outdoor grows or well-ventilated indoor spaces.

What does Moby Dick Auto taste and smell like?

It offers a rich, complex profile: citrus and pine up front, with deep woody, spicy, and incense-like undertones. The flavor is equally intense, with a smooth, slightly metallic finish.

Can I top or prune Moby Dick Auto?

It’s not recommended. Autoflowers don’t recover well from aggressive pruning. Stick to gentle LST (low-stress training) for better light exposure without stress.

How much yield can I expect outdoors?

Under optimal conditions, expect 110–250 g/plant (3.88–8.82 oz/plant). Sun exposure, pot size, and climate play a big role in final output.

Personal Experience of Pevgrow’s CEO (Alan)

I first grew Moby Dick Auto during a summer outdoor run in southern Spain, and honestly—it blew me away. I planted three in 25 L pots with a soil-coco mix, and within weeks, they were towering over my other autos. At 1.40 m (4.59 ft), they looked more like photoperiods!

The aroma started subtle but by week 6, I had to set up a carbon filter—this thing is pungent. The buds were long, thick, and absolutely covered in resin. I harvested at day 78, when trichomes were mostly milky with a touch of amber, and after a 60-day cure, the flavor was unreal: citrus punch with a smooth, earthy depth.

I’ve since recommended it to dozens of customers chasing that Haze experience without the 4-month wait. My tip? Don’t skimp on pot size, and use Bud Fuel Pro in mid-flower—it adds serious density. This strain isn’t just productive; it’s a statement. If you want an auto that performs like a champion, this is it.
