Purple Zkittlez Rbx is a boutique cultivar made for people who grow with their eyes and nose. Ethos Genetics describes her flowers as spectacular: deep purple hues completely coated in large-headed trichomes, with a complex aroma of sweet candy, assorted fruit and rich sandalwood.
She is a medium-height feminized hybrid with medium-sized flowers and strong lateral branching, so training is straightforward. Flowering takes 60 to 63 days, the yield is average, and the reward is a jar that looks and smells like something special.
If you have been searching for the Purple Zkittlez strain from Ethos seeds, this Rbx release is the one to look at, with TAC listed at 25-32%.
Purple Zkittlez Rbx Lineage
The cross is Purple Zkittlez #1 x Punchline #3, and Ethos notes that Punchline itself comes from Zkittlez x Purple Punch. That means the Zkittlez candy profile appears on both sides of the family tree, while Purple Punch reinforces the deep color and grape-berry sweetness.
Rbx stands for reversed backcross. A reversed female is crossed back toward a parent line to lock in the traits the breeder wants to keep, here the color, the trichome coverage and the candy-fruit aroma. The seeds are feminized, so expect a garden of females.
Selected numbered cuts on both sides, #1 and #3, show that this line was built from keepers rather than random parents, which helps explain how consistently she shows her purple coloring and resin.
Aroma, Flavor and Effect
Open the jar and the room fills with sweet candy and mixed fruit, a bright, sugary bouquet with real depth. Rich sandalwood sits underneath and gives the profile a woody, almost wine-like body. On some plants an acrid diesel gasoline note comes through, adding a sharp contrast to the sweetness.
Ethos tags her terpene family as red wine, which fits: fruity, dark, slightly tannic and smooth. The flavor carries well into the smoke, with candy on the inhale and sandalwood on the finish.
She is a classic hybrid in effect, and the breeder highlights her flavor and effects together as extraordinary. Expect a balanced, pleasant experience that relaxes the body while keeping the mood bright.
Growing Purple Zkittlez Rbx Indoors and Outdoors
Ethos rates her for intermediate and pro growers, yet also notes that she is easy to grow in any environment. Medium height and medium-to-short internodes keep her tidy, and strong lateral branching means topping and LST quickly build a wide, even canopy.
Feeding is simple: she is not a big feeder, so go easy on nutrients and let her tell you when she wants more. What she does love is light. Give her strong, even intensity indoors and full sun outside, and the trichome coverage will reward you.
She thrives in tents, greenhouses and outdoor gardens alike. Cooler nights near the end of flowering can bring out even deeper purple coloration. Keep humidity moderate as the flowers finish.
The yield is average, but this is a quality-first cultivar. Her frosty, deep purple flowers have real bag appeal, and the big trichome heads make her worth a try for hash and rosin.
