Crystal Seeds

Genetics & effects

Crystal is a feminised photoperiod hybrid combining White Widow × Northern Lights genetics. Its 60% indica and 40% sativa profile brings together dense flower structure, vigorous branching and a generous coating of sparkling resin. THC is listed at 15–25%, while CBD is listed at 0–2%; expression can vary with phenotype and growing conditions.

The aroma blends diesel and skunk with sweeter pine and earthy notes. Myrcene, caryophyllene and pinene are prominent within the listed terpene profile. Individual experiences differ, but Crystal is often described as beginning with a happy, uplifting and talkative feeling before settling into a more relaxed mood. Its combination of bright and grounded impressions may appeal to growers seeking a balanced hybrid rather than an entirely one-sided character.

Growing in Australia

Crystal is rated as an intermediate grow and can suit temperate areas as well as cooler regions with shorter summers. In Australia, outdoor planting generally aligns with spring, from September to November, once local conditions are reliably warm. Select a position with strong direct light, airflow and protection from prolonged wet weather. Local climate, soil, container size and seasonal variation will influence final height, timing and yield.

These feminised seeds are intended to produce female plants, although environmental stress can affect development. Consistent light schedules, careful watering and regular observation are useful throughout the cycle. Explore more feminised seeds or browse photoperiod varieties for comparison.

Indoor

Indoors, Crystal may reach up to 160 cm and has a listed flowering period of approximately 8–10 weeks. Its branching responds well to early canopy shaping, helping light reach more flowering sites. Allow enough vertical room for the transition into bloom and support heavier branches as flowers gain weight.

A stable environment is especially valuable for its compact, resinous flowers. Maintain steady airflow through and beneath the canopy, avoid persistently high humidity and allow the growing medium to dry appropriately between waterings to reduce mould risk. Under favourable conditions, indoor production is listed at up to 550 g/m², but this figure is a potential rather than an assured outcome.

Outdoor

Outdoors, plants may grow up to 180 cm, making discreet placement and adequate spacing worth considering. Crystal’s relatively short flowering window can be useful in cool, short-season areas, though site selection remains important. Morning sun can help moisture disperse after dew, while shelter from heavy autumn rain may protect dense flowers.

Outdoor production is listed at up to 500 g per plant in favourable conditions. Results depend on sunlight, root space, nutrition, weather and grower experience. Inspect inner flowers regularly as autumn approaches, particularly after humid or rainy periods.

Harvest

Australian outdoor harvest commonly falls between March and May. Rather than relying only on a calendar date, watch flower maturity, aroma development and trichome appearance. Indoor timing is usually measured from the start of flowering, with most plants finishing within the listed 8–10-week range. Handle mature flowers gently to preserve their resin and distinctive sweet, skunky, pine and earthy character.
