Quick answerRS11 is an indica-dominant hybrid bred from Pink Guava and OZK. Growers seek it out for a tropical guava-and-berry nose sitting on top of sharp gas, dense buds that often blush pink and purple, reported THC of 20-25% and a 9-10 week flowering time indoors.

What is the RS11 strain?

RS11 takes its name from Rainbow Sherbet #11, the eleventh plant kept from a West Coast seed hunt and the one that outshone its siblings. It belongs to the sherbet-family wave of modern exotics, where loud fruit sits on a fuel backbone and the flowers are expected to look as good as they smell.

The two halves of the cross are easy to taste. Pink Guava supplies the tropical side: ripe guava, berry and a sugary, almost juicy top note. OZK pulls in the opposite direction with a funky, gassy depth and much of the potency. Neither parent dominates; the sweetness lands first and the fuel follows a beat later.

In the room, RS11 grows short and sturdy with rounded, tightly packed buds. Under cooler nights the calyxes can turn rose and violet beneath a thick coat of trichomes, which is a big part of its reputation. These feminized seeds are bred to produce female plants, so each seed you pop is aimed at harvestable flower.

How it feels

Consumers commonly describe a playful, giggly opening that slides into an easy, wraparound body calm. At moderate amounts it stays social; larger amounts lean heavier.

  1. First 10 minutesBubbly and giggly

    A light, cheerful lift that tends to make conversation easy.

  2. Around the hour markSmooth body calm

    The indica side settles in as a relaxed, unhurried feeling.

  3. Later in the sessionSlow and cozy

    Bigger servings drift toward a heavy, quiet evening mood.

Commonly reportedGigglyEuphoricRelaxedCalm

Reported THC of 20-25%: start low and give it time before taking more. Commonly reported downsides include dry mouth and dry eyes, and some people report anxiety or dizziness at high doses. General reports, not medical guidance.

Aroma, flavor and terpenes

Ripe guava and mixed berry hit first, followed by a tropical sweetness and a gassy, funky finish that lingers on the exhale. The smell builds sharply in the last three weeks of flower, so a carbon filter is a must.

Flavor notesGuavaTropicalBerryGas

Hang branches at about 60°F and 60% humidity for 10-14 days, then cure in jars for three weeks or more. The tropical notes are the first to fade if the dry is rushed.

How to grow RS11

Rated moderate. RS11 is stout and manageable; the main work is keeping its dense, rounded buds dry and well ventilated through a slightly longer bloom.

RS11 is comfortable in a 3×3 or 4×4 ft tent. It usually tops out at 3 to 4 feet indoors and has a stocky, short-noded frame that fills a net evenly without much fuss. The extra week or so of bloom compared with many hybrids is the main thing to budget for.

Environment

  • Vegetative: 74-80°F with 55-65% relative humidity.
  • Flower: 68-80°F with RH held near 40-45%. The rounded, tightly stacked buds are the part of the plant most at risk of bud rot.
  • Late flower color: letting lights-off temperatures fall about 8-10°F below daytime in the final two weeks helps the pink and purple tones show.

Light and training

Run roughly 550-750 PPFD in late veg and 750-950 PPFD in bloom under LED. Top once at the fourth or fifth node, then use low-stress training to open the plant into a flat canopy. Strip small growth from the lower third before week three of flower so energy goes to the top sites.

Feeding

Medium feeding works best. Taper nitrogen from about week three of bloom and keep phosphorus and potassium steady. Under LED, a cal-mag supplement helps keep the leaves clean through the long finish.

Harvest timing

Expect 9 to 10 weeks after the flip. Check trichomes with a loupe: mostly milky heads keep the giggly side forward, while 15-20% amber gives a heavier, more settled finish.

Growing RS11 outdoors in the US

Outdoors, RS11 reaches roughly 5 to 7 feet and finishes around mid October. Set plants out after the last spring frost once nights hold above about 50°F, and give them the sunniest spot you have.

Because it finishes later than many hybrids, the last few weeks overlap with the start of fall weather in a lot of the country. Its compact buds trap moisture, so a cold rain or a run of foggy mornings can start mold quickly. Space plants for airflow, clear the lower interior, and keep a rain cover or hoop house ready for October. Our outdoor planting guide lists start dates by USDA zone.

Before you put RS11 in the ground, confirm that adult home growing is allowed where you live and how many plants your state permits. Review marijuana laws by state before you plant.

Will it finish where you live?

ExcellentInland California and the Southwest

Warm, dry autumns give the dense buds a clean, unhurried finish.

FairColorado Front Range and Utah valleys

The air is dry enough, but a mid-October harvest can meet early frost at altitude.

FairMidwest

Possible in southern areas; farther north, cold and wet weeks often arrive first.

PoorNortheast

Damp falls and a late finish make outdoor rot likely. Grow it indoors.

FairSoutheast and Gulf Coast

The season is long enough, but humid air in tight buds calls for a cover and strong airflow.

RS11 FAQ

Is RS11 indica or sativa?

RS11 is an indica-dominant hybrid. It grows short and stocky with dense buds, and its effects usually start playful before settling into body relaxation.

How strong is RS11?

Our supplier reports THC of about 20-25%. That is strong by any standard, though a notch below the most extreme modern strains, and actual results vary with phenotype, environment and harvest timing.

How long does RS11 take to flower?

Plan on 9 to 10 weeks of bloom after switching to 12/12 indoors. Outdoors in the US, plants typically finish around mid October.

How much does RS11 yield?

A well-run indoor space can produce roughly 1.3 to 1.6 ounces per square foot. Outdoors, healthy plants in full sun can give about 16 to 19 ounces each, depending on season length and care.

Is RS11 good for beginners?

It is rated moderate. The plant is compact and easy to shape, but its tight buds and longer bloom mean a first-time grower needs good humidity control and a carbon filter.

What do RS11 smell and taste like?

Expect guava, berry and tropical sweetness up front with a gassy, funky finish. Limonene, caryophyllene and linalool are the terpenes most often linked to that profile.

Where does RS11 grow best outdoors in the US?

Inland California and the Southwest are the best fit, thanks to warm, dry autumns that suit a mid-October harvest. In wetter regions it is a safer choice indoors or in a greenhouse.

Why do RS11 buds turn pink and purple?

The color comes from pigments that show more strongly when nights get cooler late in flower. Dropping lights-off temperatures by about 8-10°F in the final two weeks often brings out the pink and violet tones.
