Quick answerGhost Train Haze is a sativa-dominant hybrid bred from Ghost OG x Neville's Wreck. It is prized for an unusually frosty bud, a sharp citrus, pine and fuel aroma, reported THC around 25-28%, and a fast, clear-headed lift. Indoors it flowers in 9-10 weeks and stretches tall, so plan for vertical space.

What is the Ghost Train Haze strain?

Ghost Train Haze was first bred in Colorado, where it built a reputation as a sativa that does not trade potency for clarity. It pairs two very different personalities: a resin-heavy OG cut and a long-running Haze hybrid with a Trainwreck streak.

Ghost OG supplies the fuel, the sticky resin and much of the punch that keeps this strain near the top of the sativa potency charts. Neville’s Wreck, a Haze and Trainwreck cross, brings the speed: the fast onset, the tall frame, the narrow leaves and the sour citrus edge. Together they make a plant that looks and grows like a classic sativa but frosts up like a modern hybrid.

Plants stretch hard after the flip and set long, spear-shaped colas with pale calyxes buried under trichomes. Phenotypes tend to be consistent, which makes it easier to plan your space. These feminized seeds are bred to produce female plants, so each seed you start is headed for flower.

Ghost Train Haze

How it feels

Consumers commonly describe a quick, bright surge of energy and focus with a light body, then a clean taper. It is usually reached for during the day.

First few minutesFast, bright onset
A rush of alert, upbeat energy that sharpens attention.
30 to 90 minutesFocused and creative
Many people report a clear, talkative headspace suited to projects or a walk.
2 to 3 hoursClean taper
The lift fades gradually without the heavy, couch-bound finish of indica strains.

Commonly reportedEnergeticFocusedEuphoricCreative

Reported THC of 25-28% and a racy sativa profile: keep the first sessions small. Commonly reported downsides include dry mouth, dry eyes and, at high doses, restlessness or anxiety. General reports, not medical guidance.

Aroma, flavor and terpenes

Sour lemon and fresh pine needles hit first, followed by a sharp fuel note from the OG side. The smoke is bright and a little tart. In late flower the smell carries, so run a carbon filter.

Flavor notesCitrusPineFuelSour

TerpinoleneFresh, piney, herbal

Common in Haze lines and behind the airy, sharp top notes.

CaryophyllenePepper, fuel

Adds the spicy, gassy bite from the OG parent.

MyrceneEarth, ripe fruit

A softer, earthy base under the citrus.

Terpinolene-heavy buds lose their sparkle fast if dried warm. Hang branches at about 60°F and 60% humidity for 10-14 days, then cure in jars and burp them daily for the first week.

How to grow Ghost Train Haze

Rated moderate. Feeding is easy; the real job is controlling the stretch so the tops do not run into your lights.

Indoors

Veg climate: 75-85°F, 55-65% RH
Flower climate: 72-82°F, 40-50% RH
Stretch: Expect plants to double or more after the flip
Light: 800-1,000 PPFD in flower (LED)
Training: Top early, then SCROG or supercrop
Feeding: Light to moderate; sativas burn easily

Outdoors

Plant out: After last frost, nights above 50°F
Size: 6-8 ft in full sun
Harvest: Mid October
Best fit: Long, warm, dry autumns (USDA 8-10)
Watch for: Rain or early cold before week 10
Protect: Greenhouse or hoop cover to finish

Read the full indoor grow guide

Ghost Train Haze grows like the sativa it is: fast, tall and branchy, with long internodes and slender leaves. Indoors it typically lands at 4 to 6 feet, so a tent with at least 6 ft of headroom makes life easier. Keep veg short, often three to four weeks, because the real growth spurt comes after you switch to 12/12.

Environment

Vegetative: 75-85°F with 55-65% relative humidity. The strain handles warmth better than cool rooms.
Flower: 72-82°F and 40-50% RH. Long colas need steady airflow through the canopy to avoid pockets of moisture and bud rot.
Odor: an exhaust fan with a carbon filter is a must from week four of flower onward.

Taming the stretch

Plan for the flowering stretch before you flip. Top once or twice in veg, then spread branches under a SCROG net and keep tucking new growth for the first two to three weeks of flower. If a top still runs tall, gentle supercropping bends it back down without stopping growth.

Light and feeding

Run about 600-800 PPFD late in veg and 800-1,000 PPFD in flower under LED, raising the light as the canopy climbs. Feed on the light side. Haze-leaning plants show tip burn quickly, and a little less nitrogen in mid flower keeps leaves green without slowing bud growth.

Harvest timing

Most plants are ready 9 to 10 weeks after the flip, though some phenotypes like a few extra days. Watch the trichomes: mostly cloudy heads keep the effect bright and energetic, while waiting for more amber gives a slightly rounder finish.

Growing Ghost Train Haze outdoors in the US

Outside, Ghost Train Haze can climb to 6 to 8 feet and finishes around mid October. That late finish is the main thing to plan around. Get plants in the ground after your last spring frost, when nights hold above about 50°F, so they have the whole summer to build a big frame.

Warm, sunny regions with dry falls suit it best. Where autumn turns cold or wet early, the last weeks of flower can collide with rain and frost. A greenhouse or a simple hoop cover lets the plant finish its full term, and good spacing keeps air moving through the long colas. Our outdoor planting guide lists timing by USDA zone.

Check your local rules before you plant. Home cultivation is legal for adults in some states and not in others, and plant counts vary. See marijuana laws by state.

Will it finish where you live?

ExcellentInland California and the Southwest

Heat, strong sun and dry autumns let the long flowering run finish on schedule.

FairColorado Front Range and Utah valleys

Dry air helps, but a mid October finish risks early frost at elevation.

FairMidwest

The finish is late for the region, so a greenhouse or cover is the safer bet.

PoorNortheast

Cool, damp Octobers usually arrive before the colas are ripe.

GoodSoutheast and Gulf Coast

It loves the heat; spacing and airflow are key against the humidity.

Ghost Train Haze FAQ

Is Ghost Train Haze indica or sativa?

Ghost Train Haze is a sativa-dominant hybrid. It grows tall with narrow leaves and long colas, and its effects lean toward energy and focus rather than body heaviness.

How strong is Ghost Train Haze?

Our supplier reports THC around 25-28%, which is high for a sativa-leaning strain. Actual results depend on phenotype, growing conditions and harvest timing, so treat the range as typical rather than guaranteed.

How long does Ghost Train Haze take to flower?

Indoors, most plants finish 9 to 10 weeks after switching to 12/12. Outdoors in the US, plan on a harvest around mid October.

How much does Ghost Train Haze yield?

A well-trained indoor canopy can produce roughly 1.3 to 1.6 ounces per square foot. Outdoors, healthy plants in full sun can produce roughly 18 to 21 ounces each.

Is Ghost Train Haze good for beginners?

It is rated moderate. It is not fussy about feeding, but a first-time grower needs to plan for the big stretch with topping and a SCROG net, and needs enough headroom for a 4-6 ft plant.

What does Ghost Train Haze smell and taste like?

Expect sour citrus and pine up front with a sharp fuel note underneath. Terpinolene, caryophyllene and myrcene are the terpenes most often reported.

Where does Ghost Train Haze grow best in the US?

Outdoors it does best in inland California, the Southwest and the warm Southeast, where the season is long enough for a mid October finish. In colder or wetter regions, grow it indoors or under a greenhouse cover.

How do I keep Ghost Train Haze from getting too tall indoors?

Keep veg short, top early and train branches flat under a SCROG net before and during the first weeks of flower. Supercropping any runaway tops in weeks one to three keeps the canopy even and away from the light.
