How to Grow Moby Dick
Moby Dick is a towering, heavy-yielding, sativa-dominant feminized strain that crosses White Widow with Haze. It is a 60/40 sativa with a high 24-27% THC, a citrus, pine and sweet flavor, and a focused, happy, relaxed effect. Legendary for its huge harvests and potency, it is a big, rewarding plant for growers with the space to run it.
As a feminized strain, Moby Dick produces only female, flower-bearing plants, so you can skip sexing and remove the guesswork of sorting out males. Every seed goes toward productive, bud-growing plants from the start. You grow it under long days through its vegetative stage, then switch the lights to 12/12 to trigger flowering, which gives you full control over the plant’s final size and its timing, something that matters a lot with a plant this big.

Growing a Feminized Strain
Moby Dick is a photoperiod feminized strain, which means it flowers in response to the light cycle rather than its age. You keep it under long days, usually 18 hours of light, for as long as you want it to grow and build structure, then switch to 12 hours of light and 12 hours of darkness (12/12) to tell the plant to start flowering. Because every seed grows into a female, there are no males to find and remove, so your whole crop goes toward buds.
That control over timing is essential with a plant as big as Moby Dick, which can reach a towering 3 m. Flip it to 12/12 early to keep the final size in check, because it stretches hard after the switch like the haze it is. Use the vegetative stage to top and train it, and consider super-cropping or a screen to tame its height and spread the many flowering tops into an even, productive canopy.
Climate and Where to Grow It
Moby Dick favors a warm, tropical climate and, given its size, is often happiest outdoors where it has unlimited headroom to stretch into a real tree. Outdoors in the Northern Hemisphere it finishes around October. Indoors it is very much a plant for growers with tall tents and a plan to manage height, since left unchecked it will run away from you.
Its yield is exceptional, around 650 g/m² indoors in an optimized setup and 400-600 g per plant outdoors, which is why it is one of our genuine high-yielding seeds. As an energetic, uplifting sativa, its high 24-27% THC also places it among our high-THC seeds. Few strains pack this much potency into such a productive plant.
That character comes straight from its parents: White Widow lends the heavy resin, potency and sturdy structure, while a classic Haze brings the soaring, cerebral energy, bright citrus and the tall, stretchy sativa frame. Keep temperatures around 68-80°F (20-27°C) and good airflow through flowering, since its big haze colas appreciate steady movement to ripen clean.
Feeding Schedule (EC Guide)
Moby Dick is a big, vigorous, hungry plant, so feed it steadily but do not overdo the nitrogen, which sativas can be sensitive to. Start light while it is young, build well through the vegetative stage this plant needs, shift toward phosphorus and potassium once it flips into flower, then flush at the end so the citrus and pine notes come through clean. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.5-0.7 | Very light feed while roots establish |
| Vegetative | 1.2-1.6 | Build nitrogen as the big frame develops |
| Early flower | 1.4-1.7 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.6-1.9 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you flip it to 12/12, Moby Dick finishes in about 9 to 10 weeks, quick for such a big, haze-influenced sativa thanks to its White Widow side. It builds long, resinous, chunky colas up its tall frame, developing a bright citrus, pine and sweet aroma as it ripens. The resin is heavy for a sativa, a clear sign of the potency and quality behind its reputation.
Yields are exceptional at around 650 g/m² indoors and 400-600 g per plant outdoors. Keep the tall colas well supported, use a trellis or stakes, and keep the canopy even so light reaches every flowering top. Harvest when most of the trichomes have turned cloudy for a bright, clear, focused effect, or wait for a little amber for a slightly rounder finish.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. With such a big harvest, make sure you have the dark, ventilated space to dry it all slowly and evenly, because a gentle dry protects the bright citrus, pine and sweet aroma that defines the strain.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what locks in the citrus, pine and sweet notes and smooths the smoke, turning a freshly dried haze harvest into the fresh, clean, classic result Moby Dick is known for.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Moby Dick is a resinous plant for a sativa, and with such a big harvest there is plenty of trim, so it is well worth saving for dry sift, bubble hash or rosin. That resin and bright, citrus-pine aroma make the trim genuinely valuable, turning a mountain of offcuts into a flavorful concentrate run rather than waste.
Flavor and Terpenes
Moby Dick leads with a bright, zesty citrus flavor over a fresh, piney edge, rounded out by a sweet undertone, the clean profile that made it famous. It is a smooth, refreshing smoke, and a good cure brings that citrus-and-pine character forward in the jar and on the inhale.
Its terpene profile frames that freshness. Terpinolene brings a fresh, herbal, piney lift that carries the zesty citrus, while myrcene forms a sweet, earthy base. Caryophyllene adds a peppery edge, and linalool with a touch of p-cymene round out a bright, fresh, piney-citrus character. Together they keep Moby Dick clean and energizing rather than heavy.
Effects and Best Use
With its high 24-27% THC and 60/40 sativa-leaning make-up, Moby Dick delivers a bright, clear-headed experience. It is reported as focused, happy and relaxed, pairing an uplifting, motivating head with a comfortable, functional quality, which makes it a classic daytime strain. Its potency is genuinely high, so even for a clear sativa a measured dose goes a long way for newer smokers.
That focused, happy, relaxed profile makes it a rewarding strain for work, creative projects or an active day, alongside its bright citrus-pine flavor. The combination of a soaring, clear-headed high, a huge yield and a clean, refreshing taste is exactly why Moby Dick remains one of the most respected feminized strains.
Common Problems and Pro Tips
Moby Dick is forgiving and beginner-friendly in temperament, but its sheer size is the one thing you must plan for. It can reach 3 m, so indoors you need a tall tent and a strategy: flip to 12/12 early, top it, and use super-cropping or a screen to keep it under control. Outdoors, give it a large container or bed and plenty of room, because it will become a genuine tree.
Gentle, low-stress training during veg opens the canopy so light reaches every bud site across its big frame, and the many flowering tops benefit from an even height. Support the long, heavy colas with a trellis or stakes as they fill out, keep the air moving around its airy haze buds, and go a little easy on the nitrogen, since sativas can show burn.
As a pro tip, treat Moby Dick as a yield machine and plan around its scale: give it the space and support it needs, feed it steadily through a long veg and bloom, and make sure you have the drying room for a very big harvest. Protect the bright citrus-pine flavor with a proper plain-water flush and a full three to four week cure, and save the generous trim for concentrates.
FAQ
Is Moby Dick a feminized strain?
Yes. Moby Dick is a photoperiod feminized strain, so every seed grows into a female, flower-bearing plant and you never have to sex or remove males. You grow it under long days through the vegetative stage, then switch the lights to 12/12 to trigger flowering, which gives you full control over the plant’s size and when it finishes.
How tall does Moby Dick grow?
Very tall. As a haze-influenced sativa, Moby Dick stretches hard after the flip and can reach around 3 m, so it is best suited to outdoor grows or tall indoor setups. To keep it manageable indoors, flip to 12/12 early, top it, and use super-cropping or a screen to control the stretch and spread the canopy.
How long does Moby Dick take to flower?
Moby Dick finishes in about 9 to 10 weeks once you switch it to a 12/12 light cycle, which is quick for such a big, haze-influenced sativa thanks to its White Widow side. Outdoors in the Northern Hemisphere it is typically ready to harvest around October. That relatively quick finish, given its size and yield, is a big part of its appeal.
How much does Moby Dick yield?
A lot. Moby Dick is one of the heaviest producers in the catalog, giving around 650 g/m² indoors in an optimized setup and 400-600 g per plant outdoors. Its huge frame is what drives that harvest, so give it space, strong light and good support for the long colas to get the most from it.
What does Moby Dick taste like?
It has a bright, zesty citrus flavor over a fresh, piney edge, with a sweet undertone. Terpinolene brings a fresh, herbal lift that carries the citrus, myrcene a sweet, earthy base and caryophyllene a peppery edge. A proper three to four week cure brings that citrus-and-pine character forward on the inhale.
How much THC does Moby Dick have?
Moby Dick is a potent strain, testing from about 24% up to 27% THC depending on the phenotype and how it is grown. Combined with its 60/40 sativa-leaning genetics, the result is a focused, happy, relaxed effect. It is unusually strong for such a clear, energetic sativa, so dose it carefully if you are newer to potent strains.
