Aspirin OG Seeds

The Kiwi Seed Bank catalogue presents Aspirin OG as a feminised, intermediate-level option with balanced cannabinoid ranges and vigorous growth potential. Its citrus-led flavour profile combines lemon, earthy, diesel and pungent notes, supported by limonene, myrcene and caryophyllene.

Genetics & effects

Aspirin OG combines CBD Silver Haze × OG Skunk genetics, producing a 60% sativa and 40% indica profile. Listed cannabinoid levels sit at 5–10% THC and 5–10% CBD, though final composition can vary with phenotype, environment and cultivation choices.

People may subjectively describe the experience as calming, relaxed, tingly or euphoric. Aroma and flavour can move from bright citrus and lemon into earthy, diesel and pungent territory. Individual impressions vary, so these qualities should be viewed as general character notes rather than fixed outcomes.

Growing in the named country

In New Zealand, Aspirin OG can suit hot, dry districts, temperate areas and cooler regions with shorter seasons. Outdoor planting generally aligns with spring from September to November, once local temperatures are stable and exposure to late cold snaps has eased. Site selection matters: prioritise strong sunlight, good airflow and soil that drains freely after rain.

This variety is rated intermediate because its potential size and dense flower development reward regular observation. Avoid overwatering, support longer branches early and maintain airflow through the canopy to reduce mould risk during humid periods. Growers should check and follow all requirements that apply in their location.

Indoor

Indoors, plants may reach up to 180 cm, making early height planning useful. Training, careful spacing and a level canopy can help distribute light across vigorous branches. The listed flowering period is 8–10 weeks, depending on phenotype and conditions.

Indoor yields are listed at up to 800 g/m² under well-managed conditions. This figure is a reference rather than an assured result; lighting, nutrition, root space, temperature, airflow and grower experience can all influence performance. As flowers gain weight, branch support may help keep the canopy open and stable.

Outdoor

Outdoor plants may grow up to 200 cm and can become broad as well as tall. Choose a discreet, sun-facing position with shelter from damaging winds but enough airflow to move moisture away from foliage. In cooler or wetter districts, a warm microclimate and rain protection near the end of the season may be useful.

The listed outdoor yield is up to 900 g per plant in favourable settings. Container size, soil quality, seasonal sunshine and weather fluctuations will affect the final amount. Inspect flowers after prolonged rain and remove damaged plant material promptly.

Harvest

New Zealand outdoor harvest generally falls between March and May. Timing will vary by planting date, latitude, phenotype and seasonal weather. Monitor flower maturity rather than relying only on the calendar, while keeping an eye on autumn humidity and rainfall.

Indoors, use the 8–10 week flowering range as a planning guide. Towards the finish, preserve airflow, keep environmental swings modest and support heavy branches. A gradual, well-observed finish is the best way to retain Aspirin OG’s distinctive colour, citrus character and pungent depth.
