About G13 Haze
G13 Haze is a sativa-dominant hybrid that blends the vigour of G13 with the classic Haze flavour and effect profile. It performs well for experienced growers and rewards attention to airflow, support and timing, especially where damp autumn conditions can threaten the crop.
G13 Haze is a sativa-dominant hybrid that leans on an energetic profile. It combines vigour with a pronounced cerebral lift.
THC levels typically sit in the high teens to low twenties, offering strong psychoactive effects. Potency can vary with phenotype and growing conditions.
CBD is low in most pheno types, usually under one percent. It is not grown for high-CBD therapeutic use.
G13 Haze descends from the classic G13 crossed with Haze lineage. The genetics deliver sativa vigour combined with a resinous structure.
Seeds are typically available as feminised to ensure female plants. Regular or auto versions may exist from some breeders.
G13 Haze is an intermediate grower that needs careful attention to ventilation and mould prevention during a rainy autumn harvest season. Extra foliar management and timely pruning reduce risk in wet weather.
Flowering generally takes 10 to 12 weeks indoors. Outdoor plants in cool climates may need similar time and careful timing.
Yield is medium to high when plants receive sufficient light and support. Outdoor yields in a cool, wet season will depend on summer warmth before the rainy autumn harvest season.
Plants grow tall with long internodes and a lankier structure. Staking or training can help support heavy colas.
Indoors G13 Haze responds well to SOG or SCROG and benefits from controlled humidity in Perthshire. Outdoors it reaches full height when sheltered and given a long season in Perthshire.
Growing G13 Haze in Perthshire requires vigilance against damp as the rainy autumn harvest season approaches. Good airflow and timely harvesting are essential to prevent mould and achieve clean buds in Perthshire.
Effects are uplifting and energetic with a steady cerebral high. The stone can sharpen focus while still allowing activity.
The flavour profile mixes bright citrus top notes with earthy undertones. A peppery spice lingers on the exhale.

Yes, G13 Haze can be counted among cool climate cannabis strains but it needs vigilant mould control and a sheltered outdoor site.
Increase airflow, remove excess foliage, space plants for ventilation and be prepared to harvest early if wet weather persists.
Moderate nitrogen in vegetative growth and a balanced PK boost in flowering; avoid overfeeding late in bloom to reduce nutrient burn.
Topping, low stress training and SCROG work well to manage height and increase light penetration.
Yes, most commercial breeders offer feminised G13 Haze to simplify a grower's crop.
Dry in a humidity-controlled room with dehumidifiers if possible and cure slowly in jars to preserve terpenes and prevent mould.
