Royal Smoothie

Overview

Royal Smoothie is a hybrid cannabis strain released by Dutch seed bank Royal Queen Seeds (RQS), crossing Purple Punch with Mimosa ^[1]. The breeder positions it as a dessert-flavored, indica-leaning hybrid with moderate THC around 19% and minimal CBD ^[1]. Unlike many strains with murky origins, Royal Smoothie's lineage is documented by a single commercial breeder, which makes its parentage relatively trustworthy compared to street-named cultivars Strong evidence.

That said, 'Royal Smoothie' is a product name, not a stabilized landrace. Phenotypes from feminized seed will vary, and unrelated clones sold under the same name in dispensaries are not guaranteed to match RQS genetics.

Chemistry: cannabinoids and terpenes

RQS lists Royal Smoothie at approximately 19% THC with CBD under 1% ^[1] Weak / limited. These are breeder estimates from in-house grows, not independent lab averages across multiple harvests — actual potency varies substantially with phenotype, cultivation, and curing.

The breeder describes a sweet, fruity, berry-forward aroma consistent with the Purple Punch and Mimosa parents, both of which often test high in caryophyllene, limonene, and myrcene in published terpene panels for those parent strains ^[2][3]. However, no peer-reviewed terpene analysis specific to Royal Smoothie has been published No data. Claims about its dominant terpene are inference from parents, not measurement.

Ignore the common marketing trope that terpene percentages above arbitrary thresholds (the so-called 'myrcene 0.5% rule') determine whether a strain is sedating. That threshold is folklore with no clinical basis ^[4] Disputed.

Reported effects

Royal Queen Seeds and consumer review sites describe Royal Smoothie as producing a balanced, uplifting head effect that settles into physical relaxation ^[1] Anecdote. Users report it as suitable for evening use without being heavily sedating.

There are no clinical trials, controlled human studies, or peer-reviewed pharmacology on Royal Smoothie specifically No data. This is true for virtually every named cannabis strain — strain-specific effect claims come from breeder copy and aggregated self-reports on sites like Leafly, which are not controlled data ^[5]. The 2022 review by Smith et al. found that strain names are poor predictors of chemical composition or subjective effects across samples ^[6] Strong evidence.

If you want to predict how Royal Smoothie will affect you, the THC percentage of the specific batch you buy, your tolerance, dose, and set/setting matter far more than the name on the jar.

Lineage

Royal Smoothie is officially Purple Punch × Mimosa per Royal Queen Seeds ^[1].

• Purple Punch: A Larry OG × Granddaddy Purple hybrid attributed to Supernova Gardens, popular for grape-candy flavor [evidence:weak on exact origin].
• Mimosa: Clementine × Purple Punch, bred by Symbiotic Genetics Strong evidence.

Note that Purple Punch appears on both sides of the family (directly, and through Mimosa), which would tend to concentrate Purple Punch traits in the offspring. This is not disputed lineage in the usual sense — RQS owns and documents the cross — but anyone selling 'Royal Smoothie' clones outside RQS-derived seed stock is making an unverifiable claim.

Cultivation basics

Per the breeder ^[1]:

• Flowering time indoors: 7–8 weeks
• Indoor yield: roughly 500–550 g/m² under optimized conditions
• Outdoor harvest: early October in the Northern Hemisphere
• Height: medium, manageable for tent grows
• Difficulty: rated beginner-friendly

These figures are breeder-reported under their own conditions and should be treated as best-case Weak / limited. Real-world results depend heavily on light intensity, nutrient regimen, training, and phenotype selection from feminized seed. Expect a range, not a guarantee.

Marketing vs. reality

What's reasonably solid:

• Documented parentage from a named breeder ^[1].
• Approximate flowering time and yield range (in line with similar Purple Punch / Mimosa crosses) Weak / limited.
• General flavor profile (sweet, fruity) consistent with parent terpene profiles Weak / limited.

What's marketing folklore:

• Specific effect predictions ('uplifting then relaxing,' 'great for stress'). These are not strain-specific clinical findings; they're copy No data.
• The implication that 'indica-dominant' tells you how it will feel. The indica/sativa distinction does not reliably predict effects or chemistry ^[6] Strong evidence.
• Precise THC numbers. Treat any single percentage as a ballpark, not a spec.

If you're shopping for Royal Smoothie, ask for a current certificate of analysis (COA) showing cannabinoids and, ideally, terpenes for the specific batch. That's worth more than any strain description.
