Purple Sunset Rbx2 by Ethos Genetics

Purple Sunset Rbx2 is versatile, vibrant and impressively purple. Ethos Genetics stacked Purple Punch and Mandarin genetics back into Mandarin Sunset to create a feminized hybrid with tangerine-sized nugs from head to root, wrapped in sweet and spicy citrus, berry and floral terpenes.

Her iconic purple hues come on heavy as she ripens, turning a green canopy into a sunset of violet and orange. Strong lateral branching, good vigor and a fast flowering time of 56 to 60 days make her a grower’s dream, and she is beginner friendly to boot.

For anyone looking for Ethos seeds that combine color, a high yield and an easy-going growth habit, the Purple Sunset strain is a standout. TAC is listed at 25-30%.

Purple Sunset Rbx2 Lineage: A Mandarin Sunset Backcross

The pedigree reads (Purple Punch x Mandarin Sunset) x (Purple Punch x Mandarin Cookies) x Mandarin Sunset. Two Purple Punch hybrids were combined, one carrying Mandarin Sunset and one carrying Mandarin Cookies, and the result was taken back to Mandarin Sunset to reinforce her structure, citrus terps and vigor.

That is what the Rbx2 suffix refers to. Rbx stands for reversed backcross, and the number points to a further round of backcrossing toward the recurrent parent. The seeds are feminized, so the garden should be all females.

Mandarin Sunset and Mandarin Cookies are two of the most important plants in the Ethos story, and Purple Punch adds the grape-berry sweetness and deep color. The blend lands somewhere between dessert and citrus grove.

Aroma, Flavor and Effect

The nose opens with sweet and spicy citrus, like tangerine peel dusted with pepper. Berries follow, then a soft floral note that lifts the whole profile. The terpene families Ethos lists are berry and orange-grapefruit, and they shine after a slow dry and cure.

Smoke is smooth and sweet, with citrus on the inhale and berry jam on the exhale. The flavor is consistent from the first draw to the last, which makes her a solid pick for rosin and flower alike.

Ethos describes her as a euphoric hybrid with no couch-lock. She works as a calm, easygoing daytime companion or as a mellow, happy evening smoke, depending on the dose and the moment.

Growing Purple Sunset Rbx2 Indoors and Outdoors

This is one of the more beginner-friendly plants in the catalog, rated for every grow level. She is medium in height with medium internodes, strong lateral branching and good vigor, so she is easily trained for any system, whether that is a SCROG net, a manifold or simple topping and LST.

Indoors, a cooler night temperature in the last weeks of bloom can deepen the purple. As she flushes, the color comes on fast, so plan your photos for the final week. The flowers fill out chunky and dense, and a bigger plant will appreciate some support for the colas.

Outdoors and in greenhouses, Purple Sunset Rbx2 thrives. Her 56 to 60 day flowering window keeps the harvest well ahead of the worst autumn weather in many regions, and her vigor helps her recover quickly from wind or heavy rain.

Expect a high yield of dense, colorful flowers that look as good in a jar as they do on the plant.
