RS11 Seeds, short for Rainbow Sherbert #11, represent one of the most coveted hype strains to emerge from the Wizard Trees breeding program in California. Selected as phenotype number eleven from the Pink Guava x Sunset Sherbert x OZK cross, this sativa-leaning hybrid built a cult following between 2022 and 2024 thanks to its loud tropical guava aroma, creamy sherbert finish and reported THC numbers between 28 and 32 percent. Collectors, dispensary patients and seasoned home growers seek out RS11 not just for the high but for the prestige of running an authentic exotic. This page walks through lineage, terpene chemistry, effects, indoor and outdoor cultivation, yields, pricing, sourcing and international shipping considerations.
RS11 stands for Rainbow Sherbert #11, and the number is not decorative. It marks the eleventh phenotype Wizard Trees pulled from a single packet of Pink Guava crossed with Sunset Sherbert and OZK. The breeding team, based in California, popped a large batch, selected the standout cut for terpene loudness and structure, and locked it as the keeper. Early circulation happened through private clone networks in Los Angeles, where a handful of cultivators ran small drops that sold out within days of being announced on social media.
Within the hype strain hierarchy, RS11 occupies a tier alongside Zkittlez, Gelato 41 and Runtz, but with a much narrower clone footprint that kept prices elevated. Eighths in licensed California dispensaries routinely cleared 70 to 90 dollars when stock appeared, and certain top-shelf jars pushed past 100. Influencers and judges at the Zalympix and similar invitational events helped cement its reputation, and the strain has appeared in cup placements that further tightened demand against an already limited supply.
Seeds differ from clones in important ways for RS11 buyers. Regular seed runs from Wizard Trees are scarce and usually reserved for collaborators, while feminized and S1 selfings have reached the wider market through authorized partners. Authenticity is the central problem because so many seed banks list "RS11" packs that trace back to unrelated open pollinations. The original phenotype shows specific markers, including purple-tinged calyxes and a guava-forward nose, which serious hunters use to validate their finds.
The typical buyer of RS11 Seeds falls into three groups. Collectors want the badge of running a genuine Wizard Trees release. Micro-growers and SOG cultivators appreciate the medium height and dense flower formation that pays back small footprints. Cost-conscious patients compare the price of a six-seed pack against months of dispensary eighths and quickly see the home-grow advantage. Before purchase, buyers should confirm the legal status of cannabis seeds in their country, since rules in the United States, the European Union, Canada and Australia differ significantly.
Wizard Trees emerged from a small group of California breeders who moved from clone-only releases into structured seed work around 2019. The team focused on Cookies-family and Sherbinski-adjacent crosses, hunting phenotypes that combined exotic terpene profiles with commercial yield. Their selection philosophy weights nose first, structure second and potency third, which is why their keepers often show extreme aromatic intensity rather than simply the highest cannabinoid numbers.
The original #11 cut shows medium-tall internodal spacing, broad serrated leaves with occasional purple tipping, and chunky calyx stacking that produces dense fist-shaped colas. Its terpene fingerprint reads as ripe guava layered over vanilla cream, with a faint petrol underline that emerges late in flower. When replicated in feminized seed form the keeper traits hold in roughly two out of every six plants, while sister phenotypes lean either more candy-sweet or more gas-dominant, depending on which parent expresses strongest.
The three-way cross behind RS11 reads as Pink Guava x Sunset Sherbert x OZK, and each parent contributes a distinct piece of the puzzle. Pink Guava brings the tropical fruit terpene wall that defines the strain at first sniff. Sunset Sherbert layers in creamy sweetness, tight calyx structure and the rounded shape that lets buds hold weight without splitting. OZK, the California cut of Zkittlez OG, adds the indica density and a meaningful slice of the potency, pushing total cannabinoid numbers into the high twenties.
RS11 classifies as a sativa-leaning hybrid at roughly sixty percent sativa and forty percent indica, though the daytime profile is moderated by the OZK influence. Visual markers include violet streaks through the flower at harvest, bright orange pistils that contrast with frosted sugar leaves, and a silvery trichome coating that catches light from across a tent. Bush shape is medium-tall with branching that responds well to spreading, and main colas form dense, slightly tapered cones rather than airy spear shapes.
Tracing the family tree deeper reveals interesting overlaps. Pink Guava itself comes from a Guava crossed with a Sherb Bx1 line, which means there is double Sherbert influence on the maternal side. Sunset Sherbert is a Sherbinski phenotype of Sunset Sherbet, descending from Pink Panties and Girl Scout Cookies. OZK ties the cross back into the modern Zkittlez family. Within Wizard Trees' own lineup, RS11 shares siblings and cousins such as Studio 54, Permanent Marker and Pink Certz, all of which carry recognizable terpene echoes.
Genetic stability in feminized form is acceptable but not perfect. From a pack of six, growers typically see two phenotypes leaning close to the original keeper, two leaning toward Pink Guava dominance, and one or two leaning toward OZK density with reduced fruit. For serious pheno hunters the recommendation is to pop eight to ten seeds at minimum, label each plant and run them through full flower before selecting a mother. The genetics also hold real value for further breeding work, since the Pink Guava terpene base translates well into new crosses.
Before moving into terpenes and effects, it helps to summarize the core genetic facts in one place. The following table is a quick reference for anyone evaluating whether RS11 fits their grow space and collection goals. Each row pairs a parameter with a verified detail drawn from Wizard Trees' published material and seed bank listings. This kind of snapshot also speeds up comparison against other hype strains when planning a multi-strain run.
| Parameter | Detail | Notes |
|---|---|---|
| Strain Name | Rainbow Sherbert #11 (RS11) | Phenotype 11 of the original Wizard Trees pop |
| Breeder | Wizard Trees | California-based exotic breeder collective |
| Lineage | Pink Guava x Sunset Sherbert x OZK | Three-way cross combining fruit, cream and gas |
| Genetic Type | Hybrid (~60% Sativa / 40% Indica) | Daytime-leaning but with relaxing tail |
| Seed Variants | Feminized, S1, occasional Regulars | Regulars limited to breeder partners |
| Related Strains | Studio 54, Permanent Marker, Pink Certz | Share parental terpene fingerprints |
Lab analyses of RS11 consistently identify caryophyllene, limonene and linalool as the dominant terpenes, with myrcene, humulene and pinene rounding out the secondary band. Total terpene content typically lands between 2.0 and 2.5 percent of dried flower weight, which is in the loud range for commercial cannabis. The descriptive profile reads as guava forward with a sherbert cream underlay, and the entourage interaction with the high cannabinoid load is what gives RS11 its characteristic fast onset and full-body finish.
Cracking open a properly cured jar releases a wall of ripe tropical fruit. The lead note is fresh guava, followed by mango skin and a touch of sweet melon. Behind that sits a light gas signature from the OZK contribution, vanilla cream from Sunset Sherbert and a thin band of citrus zest that activates as the flower warms in the hand. After four to six weeks of properly managed cure, the aroma intensifies rather than fading, and the loud factor becomes strong enough that smell-proof storage is a practical necessity.
The smoking experience translates the nose into flavor with surprising fidelity. On the inhale, expect guava candy and a sweet citrus front. On the exhale, sherbert cream and a faint fuel finish coat the palate. Vaporized at lower temperatures around 175 to 185 degrees Celsius, the fruit and cream notes dominate. Pushed above 200 degrees Celsius, the gas and spice notes emerge, along with denser body effects. Smoke draws smoothly and rarely scratches the throat, which is partly down to the high linalool content.
Compared with other guava-leaning cultivars on the market, RS11 stands out for the balance between fruit and dessert character. A pure Pink Guava cut tends to read as sharper and more one-dimensional, while RS11 carries a fuller mid-range thanks to the Sherbert influence. Blind smoke tests with experienced consumers rarely confuse it with similar tropical hybrids, and that distinctiveness is a major driver of its commercial value. Preserving these terpenes through harvest and storage requires deliberate technique, which the following subsection addresses in detail.
The first preservation window opens at dry. Hang whole branches in a dark space held at 18 to 20 degrees Celsius with relative humidity between 55 and 60 percent. A slow ten to fourteen day dry is the target because faster drying volatilizes the lighter terpenes such as limonene and pinene. Avoid direct light at all costs since UV exposure degrades terpenes and cannabinoids together, and maintain gentle air movement without blowing directly on the flowers.
Once flower is trimmed and jarred, the cure begins. For the first two weeks, burp glass jars once a day for ten minutes to release residual moisture and exchange air. Boveda 62 percent humidity packs stabilize the environment after the initial burp phase, and storage should be in a dark cupboard or cure box. Pull samples at week four, six and eight to track the terpene peak, which for RS11 typically lands between weeks five and seven of cure.
For storage beyond six months, the priorities shift. Vacuum sealing in mylar with humidity packs slows degradation dramatically, and a cool stable storage temperature near 15 degrees Celsius extends shelf life further. Signs that terpenes are fading include a hay-like top note, loss of brightness in the fruit character and a flatter smoking experience. Catching these markers early and consolidating remaining flower into smaller, fuller jars limits oxygen exposure and protects what aroma remains.
California laboratory results for RS11 flower consistently report THC content in the 28 to 32 percent range, with some exceptional harvests touching 34 percent. CBD sits below 0.1 percent, which is typical for high-THC modern hybrids, while CBG can reach close to 1 percent and contributes to the overall cannabinoid weight. This concentration places RS11 firmly outside beginner territory, and Wizard Trees' own batch tests confirm that potency holds across multiple harvest cycles when growing conditions are consistent.
The high arrives quickly. Most consumers report effects within five to ten minutes of the first inhale, beginning with a sharp cerebral lift driven by the sativa-leaning genetics. Over the next twenty to thirty minutes, a wave of body relaxation rolls in from the OZK contribution without crossing into couch-lock at moderate doses. The peak holds for thirty to forty-five minutes, and total duration runs between two and three hours, fading into a soft landing rather than an abrupt drop.
Use scenarios match the hybrid character. RS11 fits social gatherings, creative work sessions, afternoon decompression and food-focused evenings, where its appetite stimulation becomes a feature rather than a side effect. It is generally not the right choice for bedtime, because the front-loaded cerebral activity can delay sleep onset in sensitive users. Tolerant consumers sometimes microdose vaporized RS11 in 5 to 8 milligram inhalation doses to access mood lift without the full intensity of a session.
On the medical side, the strain has reported use for chronic stress, mild to moderate depression, low-grade pain, appetite loss including ARFID contexts, and migraine relief. Side effects track the high-THC profile and include dry mouth, dry eyes, occasional paranoia in anxiety-prone users and elevated heart rate at higher doses. New consumers should start with a single inhalation, wait fifteen minutes, and titrate up from there rather than matching the dose habits of experienced smokers.
The list below summarizes the most common effect reports collected from grower forums, dispensary reviews and patient feedback. It is not a replacement for personal experimentation but offers a useful baseline of what to expect during a typical session with well-cured RS11 flower. The pattern of onset, peak and fade tends to be consistent across phenotypes that lean toward the original keeper.
RS11 is best classified as an intermediate to advanced grow. It is sensitive to root-zone pH swings, intolerant of high EC during the early stretch and demands a stable climate to fully express terpenes. Growers with at least two completed cycles under their belt will have a much smoother run than first-timers. The plant responds exceptionally well to SCROG and low-stress training, and it rewards topping and mainlining with even canopy development and bigger main colas.
Indoor flowering runs 56 to 63 days from flip, with most phenotypes finishing on the earlier end of that window. Outdoor harvest in the northern hemisphere falls in mid to late October, depending on latitude and weather. A four to six week vegetative phase produces a balanced plant for most tents, and the post-flip stretch roughly doubles plant height. Indoor finishing height typically lands between 90 and 130 centimeters, while outdoor plants in good soil can stretch from 150 to 220 centimeters.
For medium, both organic soil with quality amendments and coco coir with mineral feeding work well, but living soil setups tend to unlock the deepest terpene expression. Light schedule is conventional, with 18/6 in veg and 12/12 in flower, and PPFD targets in flower should sit between 600 and 900 micromoles per square meter per second. Daytime temperatures of 22 to 26 degrees Celsius and nighttime drops to 18 to 20 degrees Celsius produce the cleanest growth, with VPD between 1.0 and 1.3 during flower.
Dense colas make botrytis and powdery mildew real risks, especially in week five onward. A deliberate defoliation schedule with light passes in week three and a heavier pass in week five or six improves airflow through the canopy. RS11 is sensitive to nitrogen overload during flower, so taper nitrogen aggressively after week two of 12/12. The strain expresses deep purple coloration when night temperatures drop to 16 to 18 degrees Celsius during the last fourteen days, and supplemental UV lighting noticeably increases trichome density on the upper canopy.
For SCROG runs, plan on 0.6 to 1.0 square meters of canopy per plant, which usually translates to four plants in a 1.2 by 1.2 meter tent or one plant per square meter in larger rooms. LED fixtures in the 400 to 600 watt range per square meter cover photosynthetic needs without pushing leaf surface temperatures into stress territory. Exhaust ventilation should move at least 200 cubic feet per minute, and a carbon filter is non-negotiable because the loud factor of RS11 will saturate a room within days of entering flower.
Nutrient strategy benefits from restraint. Run base nutrients at roughly 75 percent of manufacturer recommendations, since RS11 burns easily at full strength. A calcium-magnesium supplement at 1 to 2 milliliters per liter prevents tip burn and supports flower density, and a PK boost between weeks four and six adds weight to forming colas. A clean flush over the final seven to ten days clears residual salts and improves the smoothness of the smoke after cure.

Availability of regular RS11 seeds is extremely tight. Wizard Trees releases regulars in small batches to a short list of partners, which means most public market listings are feminized or S1 versions. Authenticity is the central concern because the demand has spawned a wave of counterfeit packs sold under the RS11 name. Real breeder packs ship with serialized authentication, often including QR codes that link back to a Wizard Trees verification page, and authorized distributors are listed publicly on official channels.
Pricing reflects the scarcity. Feminized six-seed packs typically range from 150 to 300 US dollars, S1 selfings begin around 400 dollars, and the rare regular packs that surface can clear 500 or more. The premium is a direct consequence of the limited release strategy, and it tracks similarly to early Zkittlez and Runtz seed pricing during their hype peaks. A pack listed for under 100 dollars should be treated with strong suspicion, because legitimate distributors do not have margin to drop that far below breeder pricing.
Choosing a reliable seed bank is the second half of the decision. Look for vendors with at least two years of consistent positive reviews, transparent refund and replacement policies, discreet packaging practices and current SSL certification on the checkout page. Genetic test certificates and breeder partnership badges are additional reassurance signals. International availability varies, and some banks restrict RS11 shipments to specific regions due to upstream supply agreements with Wizard Trees.
The order process itself is straightforward at well-run banks. Select the pack, add it to the cart, and choose between cryptocurrency, card payment or alternative methods at checkout. Tracking is provided for most shipments, and delivery times typically run three to seven days within the United States, four to ten days within the European Union and ten to twenty-one days for Australia and New Zealand. Germination guarantees and replacement policies vary, so read the fine print before completing payment, and confirm the bank's protocol if a parcel is intercepted at customs.
Counterfeit RS11 packs are common enough that recognizing the warning signs has become a practical buyer skill. The list below highlights the red flags that experienced collectors look for when scanning a new listing. Treat any combination of two or more of these signals as grounds to walk away from the purchase entirely.
Shipping options for RS11 seeds usually break into three tiers. Standard untracked post is the cheapest and slowest, tracked shipping adds visibility for a small premium, and guaranteed stealth shipping bundles discreet packaging with replacement coverage if a parcel is lost or seized. Stealth methods include vacuum-sealed mylar inside everyday objects, and the better banks rotate concealment formats to stay ahead of customs profiling. Interception rates vary by region, with the United States and most of Europe seeing very low rates and certain Asia-Pacific destinations facing higher risk.
Payment flexibility has expanded significantly in the past few years. Bitcoin, Ethereum and USDT are the most privacy-friendly options and often unlock small discounts at checkout. Bank transfers work for larger orders, and major credit and debit cards are accepted at many banks, although card processors occasionally decline cannabis-related transactions. Cash by registered mail remains an option at some vendors for buyers who prefer no digital footprint, and promo codes, cashback offers, referral bonuses and loyalty point programs further reduce effective pricing for repeat customers.
Legal status of cannabis seeds varies sharply by jurisdiction. In the United States, the 2018 Farm Bill effectively legalized cannabis seeds as a collectible item nationwide, provided the seed itself contains under 0.3 percent THC, which seeds naturally do. Within the European Union, status varies country by country, with Spain, the Netherlands and Czechia among the more permissive. Canada, Uruguay, Malta and Germany permit home cultivation within defined plant count limits, while the United Kingdom and Australia maintain grey-zone rules where seed possession is tolerated but germination remains prohibited.
Responsibility for what happens after delivery rests with the buyer. Before germinating RS11 seeds, research the specific rules in your country, state or province, since enforcement intensity varies even within permissive regions. Many seed banks frame their sales as collectible or souvenir transactions and explicitly disclaim liability for cultivation in restricted jurisdictions. Age verification at 18 or 21 years depending on the bank is standard, and buyers should treat that requirement seriously rather than as a formality.
To round out the buying process, the following short list outlines what a standard RS11 seed order typically contains when shipped by an authorized distributor. Knowing what to expect on delivery helps buyers verify that they received a complete and authentic package, and it sets a baseline for raising claims with the seller if something is missing or damaged in transit.
Collectors who add RS11 to their library often look for adjacent hype strains that share either terpene character, breeding philosophy or grow difficulty. The selections below complement RS11 by covering pastel candy profiles, exotic cocktail terpenes, dessert fruit hybrids and resin-heavy classics, giving any catalog a balanced spread across the modern exotic spectrum without overlapping the specific Pink Guava x Sunset Sherbert x OZK lane that RS11 occupies.
