Cannatonic Seeds

Genetics & effects

Cannatonic is a feminised photoperiod hybrid created from G13 Haze and MK Ultra genetics. Its balanced 50% sativa and 50% indica profile combines compact structure with steady branching, making it a versatile option for growers with some previous experience. Kiwi Seed Bank presents this cultivar as part of its feminised seed catalogue.

Reported cannabinoid levels sit at 8–17% CBD and 3–5% THC, although expression can vary with phenotype and growing conditions. Aromas and flavours commonly blend bright citrus, fresh pine and an earthy base. Myrcene, alpha-pinene and beta-caryophyllene are the principal listed terpenes.

Experiences are subjective, but Cannatonic is often described as calming, relaxed and gently euphoric while retaining a focused, happy character. Individual impressions may differ according to setting, tolerance and the finished flower.

Growing in the named country

In New Zealand, Cannatonic can suit hot, dry districts, temperate areas and cooler locations with shorter summers. Outdoor planting is generally aligned with spring, from September to November, once local conditions are settled. Choose a position with strong sunlight, good airflow and protection from persistent rain or severe wind.

This is an intermediate-level cultivar. Its moderate height is manageable, but regular observation remains worthwhile because New Zealand humidity can rise quickly. Keep the canopy open, avoid crowded foliage and check sheltered flower sites after wet weather to reduce the risk of mould. Always check the rules that apply in your location before acquiring seeds or growing cannabis.

Indoor

Indoors, plants may reach up to 100 cm. The relatively compact profile works well where vertical space is limited, while balanced branching responds to gentle canopy management. Provide consistent air movement across and beneath the foliage, particularly as flowers gain density.

The flowering period is approximately 8–10 weeks. Under favourable conditions, indoor yield potential is listed at up to 500 g/m². This figure is a reference rather than an assured outcome; lighting, environment, plant health, experience and phenotype all influence the final result.

Outdoor

Outdoor plants may grow to around 120 cm and can offer yield potential of up to 450 g per plant. In warm or temperate regions, select an open, sunny site with free-draining soil. In cool, short-season districts, use the brightest available position and prioritise shelter from late-season rain.

• Spring planting: September–November
• Preferred conditions: Sunny, airy and well drained
• Climate range: Hot and dry, temperate, or cool with a short season
• Difficulty: Intermediate

Harvest

New Zealand outdoor harvest generally falls between March and May, with timing shaped by planting date, latitude, phenotype and seasonal weather. Watch flower maturity alongside the forecast rather than relying only on a calendar date. If extended rain is approaching, inspect plants carefully and balance further ripening against exposure to excess moisture.

After cutting, dry flowers gradually in a dark space with stable airflow and moderate humidity. Slow, even drying helps retain the cultivar’s citrus, pine and earthy character. Store the finished flower in suitable sealed containers away from heat and direct light.
