Canadian Haze Seeds

Genetics & effects

Canadian Haze is a feminised photoperiod hybrid combining Diesel, Super Silver Haze and Maple Leaf genetics. Its 70% sativa and 30% indica profile brings together vigorous Haze-style growth and a more grounded structural influence. Presented in the Kiwi Seed Bank catalogue, this variety is aimed at intermediate growers who can manage stretch, airflow and changing nutrient needs.

THC is listed at 15–20%, while CBD is listed at 0–2%. Individual experiences vary, but some people describe the effects as happy, focused and creative. The aromatic profile layers berry and bright citrus over classic haze, diesel and pungent notes. Limonene, myrcene and caryophyllene are the principal listed terpenes, contributing to its lively fruit, spice and fuel character.

Growing in the named country

In New Zealand, outdoor timing should follow southern-hemisphere seasons. Spring planting generally falls between September and November, once local conditions are reliably mild. Canadian Haze is suited to temperate or hot, dry settings, although regional weather can differ significantly. Choose a position with strong direct light, steady airflow and enough room for a plant that may become tall.

Its intermediate difficulty reflects the need for regular canopy management and close observation. Avoid persistently wet root zones, and allow the growing medium to dry appropriately between watering. In humid districts, open spacing and shelter from prolonged rain can reduce the risk of mould around dense flowers. Growers should always consider the rules that apply in their location before planting.

Indoor

Indoors, Canadian Haze can reach up to 160 cm and usually flowers for around 8–10 weeks. The sativa-leaning structure may stretch after the light cycle changes, so plan vertical space early. Gentle training, branch support and an even canopy can help distribute light across flowering sites.

• Flowering: approximately 8–10 weeks
• Indoor height: up to 160 cm
• Potential indoor yield: up to 550 g/m²

Consistent ventilation is especially useful as flowers gain weight. Monitor temperature and humidity through the full cycle, rather than waiting until late flowering. Carbon filtration may also be worth considering because the diesel, haze and pungent aromas can become pronounced.

Outdoor

Outdoors, plants may reach up to 200 cm where root space, sunlight and weather are favourable. A north-facing site with good drainage is a practical choice in many parts of New Zealand. Wind protection can help limit branch damage, but avoid enclosed corners where damp air lingers.

• Outdoor height: up to 200 cm
• Potential outdoor yield: up to 700 g per plant
• Preferred climates: temperate or hot and dry

Regularly inspect branch junctions and inner growth after rainfall. Selective thinning can improve airflow, while supports may help carry mature flower weight. Cooler or wetter regions may produce different timing, size and output from the listed figures.

Harvest

For spring-planted outdoor crops, harvest in New Zealand generally falls between March and May. Exact readiness depends on planting date, local climate and seasonal conditions. Look for mature flower development and changing pistil and trichome appearance rather than relying on the calendar alone. Indoor plants are typically ready after their listed 8–10 week flowering period. Yield, height, aroma, colour and potency remain dependent on environment and grower technique.
