RS11 F1 by Barney's Farm

RS11 F1 brings one of the most talked-about modern cultivars into Barney’s Farm’s Precision F1 Hybrids line. Bred from Pink Guava x OZK, it is a 70% indica, 30% sativa feminized hybrid with THC around 27% and a sweet berry, fruity and pine profile wrapped in sticky resin.

Each Precision F1 Hybrid comes from crossing two stable parent lines. The first-generation seeds that result are genetically consistent, so plants grow with the same height, branching and finishing time. On top of that uniformity, F1 hybrid vigor drives fast vegetative growth, even flowering and strong yields across the whole crop.

Indoors, RS11 F1 reaches 100–120 cm (39–47 in) and yields up to 650 g/m² (2.13 oz/ft²) after 56–65 days of bloom. Outdoors, plants grow to 150–200 cm (59–79 in) and can produce up to 800 g/plant (28.2 oz/plant), ready in the third to fourth week of September.

Pink Guava x OZK Lineage and the F1 Advantage

Pink Guava contributes bright, tropical fruit and a candy-sweet nose, while OZK adds a gassy, resin-heavy backbone and dense indica structure. Barney’s Farm stabilized both lines and crossed them to create an F1 that shows the fruity, dessert-like character with very little variation from plant to plant.

Plants grow stout and bushy with tightly packed lateral branches. Colas turn into rock-solid structures ranging from deep forest green to rich purple, highlighted by fiery orange pistils. The resin layer is so thick that trimming gets sticky fast, and the finished buds look striking in the jar.

RS11 F1 is a feminized photoperiod strain: plants are female and flower once the light schedule moves to 12/12. Starting each run from fresh F1 seed keeps the same vigor and uniformity, which later generations would lose.

Aroma, Flavor and Effect

Cured RS11 buds release waves of sweet berries and ripe cherry, layered over earthy pine. Cracking a bud open adds subtle citrus that dances around the dominant fruit, giving a refined balance of sweetness and earthiness.

The flavor opens with sweet berry candy and pronounced cherry, like biting into ripe summer fruit. Creamy dessert notes and fresh pine build in the middle, and the finish stays sweet with a light earthy touch.

Barney’s Farm lists the effect as relaxing, happy and balanced. A gentle mood lift arrives first with a clear head, then slowly spreads into a calm, comfortable body feeling without heavy sedation. It works for late afternoons as well as evenings.

Growing RS11 F1 Indoors and Outdoors

Indoors, plants finish at a compact 100–120 cm (39–47 in), perfect for standard grow tents. RS11 F1 responds very well to topping, LST and mainlining, which let you shape an even canopy for your space and light. Strong branches carry the dense, resin-coated flowers without much staking. Flowering takes 56–65 days on 12/12 with yields of up to 650 g/m² (2.13 oz/ft²).

Outdoors, RS11 F1 reaches 150–200 cm (59–79 in) and can deliver up to 800 g/plant (28.2 oz/plant), finishing in the third to fourth week of September in the Northern Hemisphere. That early harvest is a real advantage in regions where autumn turns wet.

Barney’s Farm notes reliable nutrient uptake and good resistance to common growing problems, so this F1 suits growers of every skill level, from first runs to dialed-in rooms.
