RS11 F1

RS11 F1 is a modern Pink Guava x OZK cross from Barney’s Farm Seeds, available here as feminised seeds. It carries a 70% indica and 30% sativa balance, with THC listed at 27%, so it’s aimed at shoppers who want a strong, fruit-led strain with a settled, relaxing edge rather than a light daytime smoke.

The F1 part matters here because Barney’s Farm presents RS11 F1 as a first-generation hybrid selected for vigour, consistency and a more uniform crop. In practical terms, the breeder highlights healthy growth, reliable flowering and a fairly even structure across plants, which can make it easier to plan a canopy. The exact parentage is simple and appealing: Pink Guava x OZK, pairing modern fruit-heavy genetics with a deeper, earthy-pine side.

In the grow room, RS11 F1 keeps to a manageable indoor height of around 100–120 cm. The plant is described as stout and bushy, with densely packed side branching and wider indica-style leaflets. Flowers build into heavy, firm colas, with colours that can run from deep green into purple, often set off by bright orange pistils. Resin production is a clear part of the appeal, with a thick trichome coat that makes the finished buds look frosty and can make trimming sticky work.

Flowering time is listed at 56–65 days. Indoor yields are given at around 650 g/m², while outdoor plants can reach 150–200 cm and produce up to 800 g per plant. Outdoor harvest is listed for the third to fourth week of September. Barney’s Farm also notes that the plants respond well to topping, LST and mainlining, so there’s room to shape them to suit the space rather than just letting them run.

The aroma is led by sweet berries and ripe cherry, backed by fruity sweetness and an earthy pine undertone. When the buds are broken open, subtle citrus hints can come through as well. It’s not described as a straight candy profile; the pine and earth give it a bit more depth and stop the fruit from feeling one-note.

The flavour follows a similar path. The first impression is sweet berry candy with clear cherry notes, then a creamier dessert character develops alongside a fresher pine touch. The finish keeps a lingering sweetness with a soft earthy note underneath. That flavour sequence is one of the nicer details with RS11 F1: fruit first, then cream and pine, then a sweet-earthy aftertaste.

Effects are described as relaxing, happy and balanced. It starts with a gentle lift in mood and a clearer head, then moves into deeper body relaxation without being presented as heavily sedating. With its 27% THC level and indica-dominant background, RS11 F1 is best suited to customers who already know they enjoy stronger modern hybrids and want a calm, fruit-forward strain with enough body to feel substantial.
