Description
Bred by Ethos Genetics from a convergence of Grape Diamonds, Grape Cake, and Grape Stomper, Grape Balls of Fire RBx is a feminised photoperiod hybrid that leans into its indica-dominant character while carrying enough sativa structure to keep canopy development manageable. The aroma profile runs deep and fruity throughout flowering, building toward a harvest that smells like a cellar full of ripe, sun-warmed grape varieties. Effects land with the weight you expect from a very high-THC cultivar, sitting above 25%, with a settling, enveloping quality that rewards evening sessions.
In the garden, this strain rewards growers who plan for production. Indoor yields land in the 450-600 g/m2 range, and outdoor or container-grown plants can push 450-750 grams per plant given room to stretch. The flowering window of 8 to 10 weeks is practical for most photoperiod indoor schedules, with the shorter end achievable in dialed-in environments. Being feminised, every seed goes toward productive canopy. Growers at any experience level will find Grape Balls of Fire RBx a reliable, high-returning cultivar worth a permanent spot in the rotation.

FAQ
All you need to know
about this product
Grape Balls of Fire RBx brings Ethos Genetics' triple-grape lineage together with 25%-plus THC and tent-filling yields, ready for growers who want serious resin with serious flavour.
This cultivar sits in the easy-to-moderate range, making it a solid choice for intermediate growers who have a harvest or two under their belt. Its indica-dominant structure keeps canopy development manageable, so you won't need advanced training techniques to get the most out of it, though some basic topping or LST will help you maximise that high-yield potential.
Grape Balls of Fire RBx is a genuine high-yielder, capable of producing 450–750g per plant outdoors and 450–600g per square metre indoors under good conditions. The indica structure keeps height in the medium range, so those numbers come from dense, resinous flower development rather than towering canopy spread.
The aroma builds steadily through flowering with an intensely fruity, grape-forward profile drawn from all three parents — Grape Diamonds, Grape Cake, and Grape Stomper. By harvest the scent is deep and ripe, almost like sun-warmed fruit, and that character carries through into the flavour on the smoke.
Flowering runs 8 to 10 weeks, which is a reasonable window for a photoperiod hybrid delivering this level of potency and yield. Pushing toward the longer end of that range typically rewards you with fuller resin development and more mature terpene expression.
