Barney's Farm RS11: A potent 70% indica hybrid with sweet berry notes.

RS11 by Barney’s Farm is a 70% indica / 30% sativa feminized Precision F1 Hybrid bred from Pink Guava x OZK, created to capture the consistency, vigour, and top-shelf appeal that genuine first-generation breeding can deliver. One of the most sought-after names in modern cannabis, RS11 combines compact, bushy growth with dense lateral branching and substantial, resin-loaded colas that can show deep green and rich purple tones set against bright orange pistils. Its terpene profile is layered and refined, opening with sweet berries, ripe cherry, and fruity candy notes, before deeper earthy pine and subtle citrus accents add balance and depth. On the palate, it stays smooth and expressive, moving from berry sweetness and creamy fruit into a lingering finish of pine freshness and soft earthiness.

With THC levels of 27%, RS11 delivers a balanced but deeply satisfying effect that starts with a gentle mental lift and clear, happy mood before settling into calm physical relaxation. That blend of joy, composure, and body ease makes it well suited to afternoon unwinding or evening use, offering a more therapeutic style of relaxation without tipping too heavily into sedation. Flowering in around 56-65 days, plants reach 100-120 cm indoors and can yield around 650 g/m2, while outdoor plants may grow to 150-200 cm and produce up to 800 g per plant by the third to fourth week of September. Strong branches, reliable F1 vigour, and good responsiveness to topping, LST, and mainlining complete the picture, making RS11 a standout modern hybrid with serious flavour, impressive bag appeal, and rewarding cultivation performance.
