Ghost Train Haze
Also known as: GTH, Ghost Train Haze #1, GTH #1
Breeder: Rare Dankness Seeds
Ghost Train Haze is one of the most decorated and potent sativa-dominant hybrids in cannabis history. Bred by Rare Dankness Seeds in Colorado in 2011, it earned High Times' 'Most Potent Strain on Earth' title in both 2012 (25.49% THC) and 2014 (27.46% THC). A rare terpinolene-dominant cultivar, it delivers explosive citrus-pine-haze aromatics with an intensely euphoric, energizing cerebral high. Not recommended for novice consumers due to extreme potency.
Lineage & Genetics
Cross: Ghost OG x Nevil's Wreck
Ghost OG is a clone-only OG Kush phenotype collected by the Devil's Harvest Krew, known for heavy resin and fuel aromatics. Nevil's Wreck is an F3 BX2 of Arcata Trainwreck (DrJays Cut) x Neville's Haze — connecting the Trainwreck and Haze lineages to produce the sativa energy and haze terpene expression.
Terpene Profile
Terpinolene — Rare dominant terpene providing piney, floral, herbaceous character; shared with Jack Herer and Dutch Treat. Contributes to energizing, cerebral effects.
Myrcene — Adds earthy depth and enhances overall cannabinoid potency
Limonene — Drives the sour citrus and lemon notes; mood-elevating
Ocimene — Contributes sweet, herbaceous complexity to the haze profile
Caryophyllene — Provides spicy pepper notes and anti-inflammatory balance
Pinene — Adds sharp pine aroma and supports mental alertness
Aroma: Sour haze and citrus pine dominate with earthy undertones and a pungent, room-filling intensity
Flavor: Citrus and pine on inhale with sour lemon, spice, and earthy haze on exhale
Effects & Experience
Onset: Rapid cerebral euphoria with immediate energy surge and mental uplift
Intensely euphoric, energetic, and creative with strong cerebral focus. Uplifting and social without sedation. Can cause paranoia or anxiety in novice users or at high doses due to extreme THC content.
Duration: 2–4 hours of intense cerebral stimulation
