Banana Guava Auto is part of Fast Buds’ new Champions Line, a breeding project that combines the breeder’s most decorated autoflower genetics into next-generation hybrids. This F1 hybrid feminized autoflower brings together two category winners from the same Autoflower World Cup: Guava Auto RF3, 1st Place Best Sativa, and Banana Jealousy Auto RF3, 1st Place Best Indica.
The Banana Jealousy side traces back to Ethos Genetics’ Banana Jealousy crossed with Banana Daddy Auto. Fast Buds’ goal was to merge Guava’s energy, potency, and exotic tropical profile with Banana Jealousy’s creamy depth, structure, and resin production.
The result leans indica at 65% Indica / 35% Sativa, with THC listed at up to 28%. She runs from seed to harvest in about 9-10 weeks, blooming automatically under an 18/6 or 20/4 light schedule, with no photoperiod switch.
Fast Buds places her in the XXL size class with a height of 80-120 cm (31-47 in). Indoors, the breeder lists 450-600 g/m² (1.5-2 oz/ft²); outdoors, plants give about 50-200 g (2-7 oz) each.
Tropical Guava Layered with Creamy Banana
The terpene spectrum is all about fruit. Tropical guava sits on top, layered over creamy banana and a mix of sweet fruit notes. Fast Buds lists banana, cream, fruits, and guava as the main taste notes, a blend that should appeal to anyone chasing exotic, modern profiles.
On paper, the pairing aims to balance the lively energy of the Guava side with the fuller, creamier character of Banana Jealousy, offering something of both worlds in a single plant.
Banana Jealousy is known for resin production, so this hybrid is a promising project for growers who like to press or wash their harvest.
An Early Champions Line Release
Fast Buds is clear that this is an early F1 release. The seeds have passed the breeder’s germination standards and the line is still going through in-house evaluation, so it suits growers who enjoy working with fresh genetics from the ground floor.
A straightforward auto routine works well: a good-sized container from day one, steady feeding, and light LST in the early weeks to spread the canopy. Keep an eye on airflow as the buds bulk up in late flower.
