Banana Daddy Rbx2 Auto by Ethos Genetics

Banana Daddy Rbx2 Auto is a vigorous, fast-growing autoflower from Ethos Genetics that crosses Banana Hammock Auto with Grand Daddy Purple. Refined through two rounds of reversed backcrossing, it delivers chunky, dense and juicy flowers with a sweet grape, floral and sandalwood profile in just 70 to 80 days from seed.

This is a plant that stacks well. Medium in height with medium to short internodes, it builds tight colas that fill out quickly, and it is described by the breeder as a great match for beginners. Expect a high yield for an autoflower, pungent terpenes and TAC in the 20-25% range.

The effect combines body relaxation with a euphoric yet focused head, an unusual balance that makes the Banana Daddy strain easy to enjoy across many occasions.

For growers looking for fast, forgiving Ethos seeds with real flavor and weight, Banana Daddy Rbx2 Auto is one of the most approachable autos in the lineup.

Lineage and Breeding: Banana Hammock Meets Grand Daddy Purple

The foundation is a cross of Banana Hammock Auto, an Ethos autoflower known for its tropical fruit and dependable timing, with Grand Daddy Purple, the classic grape-heavy indica. Banana Hammock provides the autoflowering trait and speed, while Grand Daddy Purple contributes grape sweetness, density and body.

The Rbx2 tag explains how the line was refined. Rbx stands for reversed backcross, and the 2 indicates a second round. In simple terms, Ethos Genetics backcrossed selected females into the line using reversed-female pollen, then repeated the process, tightening the traits they wanted and producing feminized seeds.

The result is a vigorous, consistent auto with chunky, juicy flowers and a fast finish, a step up in density and structure from a first-generation cross.

Aroma, Flavor and Effect

The terpene profile opens with sweet grapes, a clear nod to the Grand Daddy Purple side. Underneath sit soft floral notes and a warm, woody sandalwood base that gives the flowers depth. Some phenotypes add a light tropical or gassy edge from the Banana Hammock side.

Terpenes are rated as pungent, so expect a strong aroma during late flowering and drying. The flavor is juicy and sweet on the inhale with a smooth, woody finish on the exhale.

The effect is body-relaxing and euphoric, but focused. Rather than a heavy knockout, most growers can expect a calm body with an upbeat, clear-headed mood, making it a versatile option for both daytime and evening.

Growing Banana Daddy Rbx2 Auto Indoors and Outdoors

Banana Daddy Rbx2 Auto flowers automatically with age, so there is no need to switch the light schedule. Keep plants under 18/6 or 20/4 from germination to harvest. The full cycle from seed to harvest takes about 70 to 80 days.

Indoors, the plant grows to a medium height with medium to short internodes, producing a compact, productive frame. Start seeds in the final pot, keep early feeding light, and use gentle LST to spread the canopy. Because the flowers are chunky and dense, steady airflow and moderate humidity in late bloom help protect them.

Outdoors and in greenhouses, the plant thrives in a sunny spot, and its quick cycle allows multiple harvests in a single season across much of the US. Plant after the last frost and start another round mid-summer for an early autumn harvest.
