Passion Fruit meets Auto Melonade Runtz

Auto GrapefruitZ is part of Dutch Passion's renowned Orange Family. The photoperiod Passion Fruit contributes intense grapefruit and citrus aromas, while Auto Melonade Runtz adds exceptional resin production, strong potency and the modern American terpene profile today's growers love. The result is a highly productive hybrid autoflower with remarkable flavour complexity and outstanding overall performance.

XL buds covered in sparkling resin

Plants develop into medium to large specimens with strong lateral branches capable of supporting numerous heavy flowers. During flowering, the buds become densely coated in thick layers of white trichomes, creating an impressive frosted appearance.

Many phenotypes also develop beautiful pink, reddish or light purple hues on both the leaves and flowers, giving Auto GrapefruitZ exceptional bag appeal that immediately stands out after harvest.

A tropical fruit cocktail with grapefruit and candy

The terpene profile is one of the highlights of this variety. Sweet and sour tropical fruit aromas dominate from the beginning, reminding many growers of an exotic fruit cocktail. Grapefruit, blood orange and candy notes take centre stage, complemented by fresh citrus, subtle mint, light earthy undertones and delicate woody nuances.

Depending on the phenotype, some plants may also develop subtle chemical or Kush-like notes that add even more complexity to this modern American flavour profile.

Energy during the day, relaxation later on

The effects begin with a noticeable wave of euphoria accompanied by enhanced focus, creativity and motivation. This uplifting first stage makes Auto GrapefruitZ an excellent daytime companion for social activities, creative work or simply enjoying an active afternoon.

As the experience develops, a comfortable body relaxation gradually builds without becoming overly sedating. This smooth transition creates a versatile hybrid effect suitable for both daytime enjoyment and relaxed evenings.

Easy to grow in any environment

Auto GrapefruitZ develops vigorous growth with strong side branches and responds well to techniques such as Low Stress Training (LST), High Stress Training (HST) and other plant training methods. Its open hybrid structure promotes excellent airflow, making it suitable for indoor grows, greenhouses and outdoor cultivation alike.

Thanks to its hybrid vigour and forgiving nature, beginners can achieve excellent harvests with minimal effort, while experienced growers can fully unlock its impressive production potential using advanced cultivation techniques.

XL harvests in around twelve weeks

The complete life cycle averages around 11 to 12 weeks, although particularly fast phenotypes may finish in as little as 75–85 days from seed. Indoor growers can typically expect 500–550 g/m², while highly experienced cultivators may harvest up to 700 g/m².
