Pina Rbx2 Auto by Ethos Genetics

Pina Rbx2 Auto is a fruit-candy autoflower from Ethos Genetics that is quick to flower and finish. Bred from Pluto Auto x Peach OG and refined through a second reversed backcross, it is packed with candied flavors of pineapple, peach, grape, and sweet grapefruit.

The plant is fairly large, with a great stretch and stack: medium-sized nugs line up deep along each branch. It finishes in about 70 to 80 days from seed, carries an average yield rating, and the breeder lists a Total Active Cannabinoids figure of up to TAC 25%.

Pina, written Piña by the breeder, also anchors several other Ethos autos as a parent. If you are looking for the Pina strain itself, this Rbx2 is the core line among those Ethos seeds.

Lineage: Pluto Auto x Peach OG, Rbx2

The auto side is Pluto Auto, which supplies the day-neutral flowering trait and quick finish. The photoperiod side is Peach OG, and Ethos notes that its influence shows in the plant: vigor, stretch, and longer nodes.

Rbx2 means a second reversed backcross. Ethos crossed the line back twice with reversed females, keeping the seeds feminized and locking in the candied fruit profile. Despite the Peach OG vigor, the plant stays fast. That balance between photoperiod character and auto speed is a hallmark of Ethos cannabis genetics.

Aroma, Flavor, and Effect

The profile is all candied fruit: pineapple and ripe peach up front, with grape and sweet grapefruit rounding things out. Ethos tags the families as fruity and tropical, and calls the terpenes pungent.

On the palate, it tastes like a bag of tropical fruit candy, sweet and juicy with a light citrus snap from the grapefruit note. The flavor holds well through a careful dry and cure.

Ethos lists a euphoric effect among its highlights and places it between classic indica and classic hybrid. Expect a happy, upbeat lift that settles into a comfortable body feel, good for weekends and social sessions.

Growing Pina Rbx2 Auto Indoors and Outdoors

Indoors, run lights on 18/6 or 20/4 for the full cycle; flowering starts on its own with no light switch. The plant grows fairly large with a strong stretch, so leave some headroom above the canopy and keep the fixture at a sensible distance.

Sow straight into the final container. Feed lightly early, then increase as the stretch begins and flowers stack. LST in the first weeks spreads the branches so the deep-stacking nugs along each one get good light. Ethos describes the plant as beginner friendly, though its taxonomy rates it for intermediate to pro growers, so steady attention to feeding and humidity pays off.

The breeder lists indoor, greenhouse, and outdoor as ideal environments. Outdoors, the 70-to-80-day cycle allows more than one run per season in many US regions. Give it full sun, airy soil, and space to stretch.
