G13 Auto combines G13 genetics with ruderalis in a compact autoflowering hybrid. Its profile is listed as 80% indica and 20% sativa, with THC at 18–24% and CBD at up to 0.7%. Kiwi Seed Bank presents this variety for growers seeking a short flowering period, manageable height and a rich mix of sweet, fruity, herbal and woody notes.

Genetics & effects

The indica-dominant structure is paired with autoflowering genetics, allowing plants to move into bloom according to age rather than a change in light hours. Myrcene, caryophyllene and limonene contribute to an aromatic profile that may suggest berries, sweet fruit, herbs, wood and classic skunk.

Experiences are subjective and can vary considerably. Some people describe G13 Auto as initially uplifting or euphoric, followed by a potent, relaxing and sleepy feeling. Others may find its intensity more prominent than its brighter qualities. Setting, individual sensitivity and the finished flower can all shape how it feels.

Growing in New Zealand

G13 Auto is rated as an intermediate option and may suit hot, dry areas, temperate districts and cooler regions with short summers. New Zealand conditions differ sharply by location, so growers should account for local rainfall, wind, humidity and overnight temperatures. Autoflowering plants have a limited vegetative window, making steady early growth and minimal stress especially important.

For outdoor cycles, spring planting falls between September and November. A sunny, sheltered position can support development, while good airflow and free-draining media help reduce mould risk during humid or wet periods. Because autoflowers do not rely on shortening days to begin bloom, planting time can strongly influence the amount of useful warmth and light available.

Indoor

Indoors, plants are listed to reach up to 110 cm. The stated flowering period is approximately 8–9 weeks, though the full seed-to-harvest cycle also includes early seedling and vegetative growth. A stable environment, moderate nutrition and careful watering are preferable to abrupt changes.

  • Listed indoor yield: up to 550 g/m²
  • Height: up to 110 cm
  • Key considerations: airflow, humidity control and even light coverage

Branches may carry dense flowers, so maintaining space around the canopy can help moisture escape. Avoid keeping the root zone constantly wet, and monitor plant response before making major environmental adjustments.

Outdoor

Outdoors, G13 Auto is listed to grow up to 120 cm and produce up to 100 g per plant. Actual size and output depend on sunlight, container or root space, weather, nutrition and general plant health. In cooler districts, a warm start and protection from harsh wind can help plants make better use of their short cycle.

  • Preferred conditions: sunny, sheltered and free-draining
  • Climate range: hot and dry, temperate, or cool with a short season
  • Weather focus: watch prolonged rain and late-season humidity

Harvest

New Zealand’s broader outdoor harvest season runs from March to May, but autoflowering plants may finish earlier or at different times depending on their sowing date. Assess flower maturity directly rather than relying only on a calendar. The stated figures are reference points, not assured outcomes, and natural variation between plants is expected.
