Grape Ape Auto Seeds

Genetics & effects

Grape Ape Auto feminised seeds combine Grape Ape with an autoflowering OG Kush lineage. The result is an indica-dominant profile of approximately 80% indica and 20% sativa, paired with automatic flowering that does not depend on a seasonal light-cycle change. Outback Seed Bank presents this cultivar for growers seeking rich colour, compact structure and pronounced fruit character.

THC may fall around 18–24%, while CBD may reach up to 0.5%, though cannabinoid levels vary with environment, cultivation and testing. Experiences are subjective, but some people describe the effect as initially uplifting, cerebral or energetic before settling into a potent, relaxing sensation. Aroma and flavour may feature grape, sweet fruit and earthy skunk, with myrcene, caryophyllene and limonene among its notable terpenes.

Growing in Australia

This autoflower is considered an intermediate option and may suit temperate or hot, dry parts of Australia. Its automatic schedule can make timing more flexible than photoperiod varieties, although stable conditions remain important. Where local rules permit cultivation, spring planting from September to November offers increasing warmth and daylight. Autoflowers generally respond best to minimal disruption, so establish seedlings in their final container early and avoid heavy pruning or repeated repotting.

Actual height, timing and yield depend on climate, pot size, light, nutrition and grower experience. Figures shown are indicative rather than assured. Explore more autoflower seeds or compare the broader feminised seed collection.

Indoor

Indoors, plants may reach up to 150 cm and produce up to 500 g/m² in favourable conditions. Use an airy substrate and a container with reliable drainage. A balanced light footprint helps maintain even development, while gentle airflow can reduce the risk of mould around dense flowers.

• Flowering period: approximately 7–8 weeks
• Indoor height: up to 150 cm
• Indoor yield: up to 500 g/m²
• Experience level: intermediate

Keep environmental changes gradual. Overwatering, high humidity and strong nutrient inputs can slow an autoflower during its limited growth window. Low-stress canopy positioning may improve light access, but allow time for recovery.

Outdoor

Outdoors, choose a sunny, sheltered position with free-draining soil or a breathable container. Plants may grow up to 150 cm and yield up to 140 g each under favourable conditions. In hot, dry regions, mulch can help moderate root-zone temperature, while morning watering limits prolonged surface moisture. In temperate areas, watch late-season humidity and allow space between plants for airflow.

Purple colour may become more visible as flowers mature, particularly with cooler night temperatures, but expression varies by phenotype and environment. The grape and sweet-skunk aroma can become prominent, so site selection deserves consideration.

Harvest

The listed flowering phase is around 7–8 weeks, but assess each plant rather than relying only on the calendar. Flower maturity, aroma and overall plant fade offer useful harvest cues. For spring outdoor starts from September to November, timing may vary across Australia; the broader southern-hemisphere harvest season is March to May, although fast autoflowers can finish outside that window. Dry flowers slowly in a dark, ventilated space with steady humidity to preserve their favourite grape, fruit and skunk notes.
