How to Grow Ghost Train Haze
Ghost Train Haze is a potent, hazy, sativa-dominant feminized strain, famous for its heavy frost and strong effect. At Blimburn it is offered as Ghost Train Power, a feminized cross of Ghost Train Haze with Pellezino. It is an 80/20 sativa with a high 28-30% THC, a spicy, sweet, woody flavor, and a happy, hungry, relaxed effect.
As a feminized strain, Ghost Train Haze produces only female, flower-bearing plants, so you can skip sexing and avoid sorting out males. Every seed goes toward a productive, bud-growing plant 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.

Growing a Feminized Strain
Ghost Train Haze 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 is useful with a sativa-leaning plant like Ghost Train Haze. It is strongly sativa at an 80/20 split but, in this Pellezino cross, stays surprisingly compact at around 1.2 m, so you can flip it earlier or later to dial in its size. Use the vegetative stage to top it and spread the canopy, which opens up the flowering sites and helps its dense, frosty, resinous colas develop evenly through its 8 to 9 week bloom.
Climate and Where to Grow It
Ghost Train Haze suits a warm, tropical climate and grows well both indoors and outdoors where it gets strong light and a long, warm season. Outdoors in the Northern Hemisphere it finishes around October, so it needs a reasonably mild autumn to ripen its frosty buds fully. At a compact 1.2 m it is easy to manage in a tent or in the ground, which is a real advantage for a sativa of this potency.
Its high 28-30% THC places it firmly among our high-THC seeds, and its airy, uplifting, sativa-dominant structure sits naturally in our sativa seeds. Its classic hazy character, carried straight from the Ghost Train Haze side of its family, also places it among our haze strains, where its spicy, woody profile fits right in.
On yield it is a genuinely heavy producer, around 600 g/m² indoors and 600-800 g per plant outdoors on a well-grown specimen, which is a strong return for a compact plant. Keep temperatures around 68-80°F (20-27°C) and humidity sensible through flowering so the dense, resinous buds ripen clean and hold their spicy, woody aroma.
Feeding Schedule (EC Guide)
Ghost Train Haze is a resinous, flavorful plant that feeds moderately to hungrily, but build the nutrients gradually rather than pushing it hard early. Start light while it is young, build through the vegetative stage, shift toward phosphorus and potassium once it flips into flower, then flush at the end so the spicy, sweet and woody 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 | 1.0-1.5 | Build nitrogen gently as the plant grows |
| Early flower | 1.4-1.7 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.6-1.9 | Peak bloom feed for its resinous buds |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you flip it to 12/12, Ghost Train Haze takes about 8 to 9 weeks to finish, a fairly short bloom for such a hazy, sativa-leaning plant. It builds dense, elongated, trichome-smothered buds, developing a spicy, woody aroma with a sweet undertone as it ripens. That spicy, woody scent and heavy frost are the signature of its Ghost Train Haze and Pellezino parents, and the sheer amount of resin it packs on is one of its calling cards.
Yields are strong, around 600 g/m² indoors and 600-800 g per plant outdoors on a well-fed specimen. Keep the lanky colas supported and the canopy open so light reaches the lower buds, feed it steadily through flower, and harvest when most of the trichomes have turned cloudy with a few amber for the fullest spicy-woody flavor and the most rounded effect.
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. A slow, even dry matters with such dense, resinous buds, because they can stay damp in the middle while the outside dries, and a gentle dry protects the spicy, sweet and woody 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 brings out the full spicy, sweet and woody character and smooths the smoke, turning a freshly dried harvest into the rich, pungent, full-bodied result Ghost Train Haze is known for.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Ghost Train Haze is an extremely resinous, frosty plant, so its trim is excellent for dry sift, bubble hash or rosin. That heavy resin and spicy, woody aroma make the trim genuinely valuable, turning offcuts into a potent, flavorful concentrate run rather than waste, a real bonus with such a high-THC cultivar.
Flavor and Terpenes
Ghost Train Haze leads with a spicy, woody flavor over a sweet undertone, the pungent, hazy profile it inherits from its parents. It is a full-bodied, characterful smoke, and a good cure brings that spicy-woody character forward in the jar and on the inhale, with the sweet note rounding it out.
Its terpene profile frames that flavor. Caryophyllene drives the peppery, spicy edge, while terpinolene adds the fresh, woody, herbal lift that so many haze strains share. Myrcene brings a soft, earthy base underneath, and linalool a gentle floral touch. The sweet undertone itself comes through from its genetics, with these terpenes giving the spicy, woody, herbal frame around it.
Effects and Best Use
With its high 28-30% THC and sativa-dominant 80/20 make-up, Ghost Train Haze delivers a potent, lively experience. It is reported as happy, hungry and relaxed, pairing a bright, cheerful lift with a comfortable body, and it is the kind of strain that can leave you reaching for a snack. The potency here is genuinely high, so a measured dose goes a long way, especially for newer smokers who may prefer to start slow.
That happy, relaxed profile with a clear, upbeat head makes it a versatile strain for daytime or social use, well matched to its spicy, woody flavor. The combination of real haze potency, a pungent, characterful taste and a lively, upbeat effect is exactly why Ghost Train Haze remains a favorite among sativa-leaning feminized strains.
Common Problems and Pro Tips
Ghost Train Haze is forgiving and beginner-friendly, and in this Pellezino cross it stays more compact than a typical haze, which makes it easier to manage. Its dense, frosty, resin-packed buds are the main thing to plan for. Those tight colas can trap moisture, so keep the air moving and ease the humidity down as the flowers fill out to avoid trouble in the heart of the bud.
As a sativa-leaning plant it can still stretch after the flip, so support the taller colas and keep the canopy even so light reaches every bud site. Gentle, low-stress training during veg opens the canopy nicely, and doing your topping and training early, while the plant is still growing, keeps the structure tidy and productive right through flower.
As a pro tip, make the most of its pungent flavor and frost: keep the feed sensible rather than heavy at the finish, since over-feeding can mute the spicy, woody notes, and protect those terpenes with a proper plain-water flush and a full three to four week cure. Save the frosty trim for concentrates, and harvest when most trichomes are cloudy with a few amber for a rich, flavorful result.
