Green Crack Auto Seeds

Genetics & effects

Green Crack Auto is a feminised autoflower built from an Afghani, Skunk #1 and ruderalis autoflowering lineage. Its listed profile is 60% sativa and 40% indica, bringing together lively sativa character, sturdy indica influence and the convenient flowering trigger of ruderalis genetics. Plants move into bloom according to maturity rather than a strict change in daylight hours, making this an approachable choice for growers exploring autoflower seeds.

THC is listed at 15–21%, while CBD is listed at 0–0.7%. Experiences are personal and can vary, but this cultivar is commonly associated with an uplifting, euphoric first impression that may settle into a relaxed and calming feel. Its flavour profile combines fruity mango sweetness with softer floral detail. Myrcene, caryophyllene and pinene are the principal listed terpenes, contributing ripe fruit, spice and fresh herbal accents.

Growing in New Zealand

Green Crack Auto is rated as beginner-friendly and suits both temperate conditions and hot, dry periods. In New Zealand, spring planting falls between September and November. Autoflowers run on their own schedule, so spring-started plants may finish before the conventional late-season harvest. Later, season-aligned sowings can lead towards the main March to May harvest window.

Regional conditions differ considerably. Warm northern areas may offer a longer outdoor window, while cooler southern locations call for closer attention to overnight temperatures, wind and autumn moisture. Choose a bright position with good airflow and free-draining growing media. Shelter from prolonged rain can reduce the risk of mould around dense flowers. Avoid unnecessary repotting or heavy training once rapid growth is under way, as autoflowers have limited time to recover.

Indoor

Indoors, plants are listed to reach up to 90 cm, making them suitable for spaces where vertical control matters. A stable environment, consistent light and gentle early canopy shaping can help maintain even growth. Use a final container with dependable drainage and leave enough space between plants for airflow.

Indoor flowering is listed at approximately 7–8 weeks, with potential yields of up to 600 g/m² under favourable conditions. These figures are reference points rather than assured outcomes; lighting, container size, nutrition, environment and grower experience all influence performance.

Outdoor

Outdoor plants are listed to reach up to 125 cm and may produce up to 300 g per plant in favourable settings. A sunny, sheltered site can support steady development, while airflow helps manage humidity after rain. In exposed locations, discreet support may help branches handle wind and the weight of mature flowers.

Because the autoflowering cycle is relatively quick, plan sowing around local temperature and rainfall patterns rather than daylight alone. Check plants regularly as autumn approaches, particularly during damp spells or sharp temperature changes.

Harvest

For New Zealand’s traditional outdoor calendar, harvest generally falls from March to May, although spring-planted autoflowers can be ready earlier. Assess maturity from the plant itself rather than relying only on a date. At peak readiness, Green Crack Auto is expected to show its strongest fruity, mango and floral character. Kiwi Seed Bank presents this cultivar as a compact, accessible option for growers who favour quick autoflowering development and bright flavour.
