RS11

Why you should buy RS11 feminised Seeds

If you're chasing knockout potency, boutique flavour, and a surprisingly laid-back grow, RS11 is the kind of strain you don’t just grow once. With genetics pulled from the heavy-hitting Pink Guava and the always-iconic OZK, RS11 brings a true exotic punch to the grow room. It's a favorite among connoisseurs for good reason.

What really sets RS11 apart is its sheer strength. Clocking in with THC levels up to 32 percent, this isn’t just strong weed. It’s one of the most potent strains on the market, full stop. And the best part? It’s beginner friendly. Whether you’ve got a few grows under your belt or you’re just getting started, RS11 gives you that top-shelf dispensary feel with homegrown effort.

Strain Overview

Origin

RS11 Fem, short for Rainbow Sherbet #11, was bred by Doja Pak and took the exotic scene by storm, originally lighting up California’s premium dispensary shelves before spreading far and wide. The cross of Pink Guava and OZK delivers the kind of genetic stability, flavour depth, and sheer bag appeal that breeders dream of. It’s a strain born from legends, made for those who want something loud, flavourful, and high performing.

Effects & flavours

The high hits quickly, starting with a bright, happy head rush that lifts your mood and sharpens your focus. It’s the kind of high that makes everything feel just a bit better. A little floaty, a little giggly, and very social. As things settle, that initial energy smooths into a more relaxed state without dragging you down. It’s mellow but clear, perfect for everything from creative work to a long laugh with mates.

flavour-wise, RS11 is a sensory overload in the best way possible. You’ll taste juicy peach, sweet citrus, and a sour-diesel twist that finishes with a soft candy note. There’s a bit of gas underneath it all that reminds you this isn’t just some fruity throwaway. It’s strong, complex, and unforgettable.

THC & CBD Levels

This is where RS11 Fem leaves the rest in the dust. With THC levels soaring up to 32 percent, it lands squarely in ultra-potent territory. It’s the kind of strain you treat with respect, even if you’ve got a high tolerance. CBD levels stay low at around 0.2 percent, which means this is all about the psychoactive experience. Intense, euphoric, and long-lasting.

Terpenes

RS11 leans heavily on a trio of standout terpenes. Caryophyllene brings that warm, spicy bite that adds depth to the body high and makes everything feel just a bit more chill. Limonene keeps things fresh and vibrant, lifting the mood and sharpening the senses. Then there’s Humulene, that earthy, herbal presence that rounds everything out and adds a little balance. Together, these terpenes make for a deeply layered smoke, both in flavour and in effect.

Growing RS11 Seeds

Grow Difficulty

Despite its elite status and head-spinning strength, RS11 is remarkably easy to grow. It’s resistant to mould and mildew, stays compact and manageable, and doesn’t fuss too much if your environment isn’t perfectly dialed in. Great choice for new growers looking to grow something special, and just as rewarding for seasoned hands running advanced setups or custom training.

Indoor vs. Outdoor Growing

RS11 handles itself beautifully indoors, with a tight structure and a final height of around 100 cm to 120 cm. Ideal for tents, cabinets, or grow spaces where vertical room is limited. Outdoors, you’ll see it stretch a bit more, hitting up to 160 cm if it’s got space to thrive. It responds well in temperate and Mediterranean climates, and greenhouses work brilliantly too. With proper airflow and light management, this plant will reward you every time.

Flowering Time & Yield

Expect flowering to take around 70 to 84 days, so give it a little patience and you’ll be rewarded. Indoors, you’re looking at yields between 450 grams per m2 and 550 grams per m2, especially if you apply light training or dial in your nutrients and light intensity. Outdoors, yields land in the 110 grams per plant to 160 grams per plant range, which might sound modest but remember this is some of the strongest flower you can grow. Quality over quantity absolutely applies here.
