Ghost Train Haze Seeds

Genetics & effects

Ghost Train Haze is a feminised, sativa-dominant photoperiod hybrid created from Ghost OG and Neville's Wreck genetics. Its profile is approximately 80% sativa and 20% indica, with listed THC levels of 18–30% and CBD of up to 0.2%. The combination brings together vigorous growth, substantial height and a layered aroma led by terpinolene, limonene and myrcene.

Spicy, sweet and woody notes form the base of the flavour, while citrus and pine add a bright, fresh edge. Individual experiences vary, but users commonly describe the effects as euphoric, energetic, focused and uplifting. The overall sensation may feel powerful, particularly with higher-THC plants, so this cultivar is generally associated with seasoned enthusiasts rather than those seeking a mild experience.

Growing in the named country

In New Zealand, Ghost Train Haze is best matched with experienced growers who can manage its height, feeding and environmental needs. Its hot, dry to temperate climate preference can suit selected local regions, though conditions vary considerably between the upper North Island, coastal areas and cooler southern locations. Spring planting falls between September and November.

This cultivar benefits from strong light, steady airflow and careful humidity management. Its long branches respond well to thoughtful canopy shaping, while close observation can reduce risk from mould during damp weather. Grow only where permitted and check the rules that apply to your location and circumstances.

Indoor

Indoors, plants may reach up to 150 cm and typically flower for about eight to ten weeks. The vigorous sativa structure can stretch after the flowering cycle begins, making early canopy planning especially useful. Low-stress training, branch support and an even light footprint can help make productive use of the available space.

• Flowering time: approximately 8–10 weeks
• Indoor height: up to 150 cm
• Indoor yield: up to 600 g/m²
• Experience level: expert

Keep air moving through the canopy and monitor moisture around dense flower sites. Stable temperatures and measured feeding are preferable to abrupt changes. Because plants can become tall and branchy, compact rooms may require more frequent shaping.

Outdoor

Outdoors, Ghost Train Haze can reach up to 225 cm where root space, sunlight and weather are favourable. Choose a warm, bright position with shelter from severe wind and enough room for lateral growth. Supports may be helpful as flowers gain weight. In wetter districts, spacing plants well and removing congested growth can improve airflow and reduce mould risk.

Its preference for hot, dry or temperate conditions makes site selection important. Growers in cooler areas may favour a sunny, protected microclimate, while those in humid regions should pay particular attention to late-season rainfall and overnight moisture.

Harvest

New Zealand's typical outdoor harvest window is March to May, although the exact timing depends on planting date, latitude, seasonal weather and plant development. Indoor crops are generally ready after the listed eight-to-ten-week flowering period.

Watch flower maturity rather than relying on the calendar alone. Outdoor plants may need protection from autumn rain as harvest approaches. Listed yields reach up to 600 g per plant outdoors or 600 g/m² indoors, but actual results vary with environment, grower skill and plant care.
