Green Crack Auto Seeds

Genetics & effects

Green Crack Auto is a feminised autoflower built from an Afghani × Skunk #1 × ruderalis lineage. Its reported balance is approximately 60% sativa and 40% indica, pairing a lively character with a more settled finish. Outback Seed Bank presents it as a compact option for growers seeking an uncomplicated addition to an autoflower seed collection.

THC has been reported at around 15–21%, while CBD is listed between 0 and 0.7%. Individual plants and finished flowers may vary according to phenotype, environment and cultivation choices. Some consumers subjectively describe the experience as uplifting or euphoric at first, followed by relaxed and calming sensations. Perception differs from person to person.

The aromatic profile leans fruity, with mango-like sweetness, floral accents and a lightly earthy edge. Myrcene, caryophyllene and pinene are among the associated terpenes, although expression can shift between plants and growing conditions.

Growing in Australia

This beginner-friendly autoflower may suit hot, dry and temperate parts of Australia. Its ruderalis heritage means flowering begins according to plant maturity rather than a changing light cycle. For a traditional outdoor warm-season run, spring planting falls between September and November, with harvest planning commonly centred on March to May. Autoflowers can finish earlier depending on sowing date and local conditions, so observe plant maturity rather than relying only on the calendar.

Good airflow, sensible spacing and shelter from prolonged rain can reduce the risk of mould. In very hot districts, afternoon shade and consistent root-zone moisture may help plants through heat spikes. Growers in cooler regions can use the warmest part of the season and choose a bright, protected position.

Indoor

Indoors, Green Crack Auto is listed at up to 90 cm, making it manageable in compact spaces. A light, airy growing medium and restrained feeding can suit its short life cycle. Keep the light schedule consistent and avoid major disruptions once flowering is underway.

• Listed flowering time: approximately 7–8 weeks
• Listed indoor yield: up to 600 g/m²
• Useful approach: gentle canopy positioning and steady airflow

These figures are reference points rather than fixed outcomes. Lighting, plant count, container size, climate control and grower experience all influence performance.

Outdoor

Outdoor plants are listed at up to 125 cm and may produce up to 300 g per plant in favourable conditions. Select a sunny site with free-draining soil, and allow enough room for air to move around the foliage. Its moderate stature can make routine inspection straightforward, while the autoflowering habit supports a relatively quick seasonal run.

Rainfall and humidity differ greatly across Australia. Check flowers after wet weather, remove damaged plant material and avoid leaving dense foliage persistently damp. In exposed locations, simple wind support may help maintain stable growth.

Harvest

Plan the main Australian outdoor harvest window for March to May, while remembering that September–November plantings of an autoflower may mature sooner. Look for swollen flowers, changing pistil colour and trichome development as practical maturity cues. Indoor crops follow their own start date, with the listed flowering period providing a general guide. Final aroma, colour, potency and yield remain dependent on phenotype and environment.
