Market Status: The "Breeder's Secret"; this is not typically found as a standalone seed pack. It is the proprietary breeding cut used as the pollen donor for the 2023 hit Granny Candy. It fuses the massive frost and candy gas of the Runtz family with the signature "baked goods" terpene profile of HSC's flagship Blueberry Muffin.
THC Content: 24% – 28% (Estimated based on lineage)
Dominant Terpenes: Caryophyllene, Myrcene, Limonene, Linalool
Key Effects: Deep Relaxation, Euphoric Mood Lift, Appetite Stimulation, "Comfort" Stone
Behind every great strain, there is often a hidden parent that does the heavy lifting. For the award-winning Granny Candy, that parent is W. Runtz Muffin.
While Humboldt Seed Company hasn't released this strain as a commercial standalone, it is a crucial piece of their genetic library. By taking the world-famous White Runtz—known for its snow-white trichome coverage and sugary candy flavor—and crossing it with their own legendary Blueberry Muffin, they created a plant that smells like a fruit tart coming out of the oven.
It serves as the "Flavor Anchor" in breeding. It takes the sharp, minty profile of strains like Mountaintop Mint and softens them with a layer of sugary dough and berry preserves.
History and Lineage: The Candy-Bakery Fusion
This strain represents the collision of two massive hype trains: the modern Runtz craze and the timeless Humboldt terpene preservation.
The "W" (White Runtz): While sometimes debated (Watermelon vs. White), the "W" almost certainly refers to White Runtz. This parent provides the distinct "Zkittlez x Gelato" candy gas profile, the deep purple potential, and the thick, sandy layer of trichomes that gives the plant its frost.
The "Muffin" (Blueberry Muffin): HSC’s crown jewel. This parent is famous for one thing: smelling exactly like a freshly baked blueberry muffin. It brings the uniform structure, the fast flowering time, and the "doughy" bottom note.
The Synthesis: W. Runtz Muffin combines these to create a profile that is less "Gas" and more "Pastry." It eliminates the sometimes biting chemical notes of Runtz and replaces them with a smooth, buttery berry finish.
Terpene Profile: Fruit Tart and Powdered Sugar
If you were to smoke this strain on its own, you would be treated to a dessert-heavy experience.
Dominant Terpenes
Caryophyllene (The Bake): The dominant terpene that bridges the gap between the "Cookie" genetics of Runtz and the "Muffin" genetics. It smells of warm spices and baked dough.
Limonene/Linalool (The Berry): These terpenes combine to create the sweet, floral berry aroma that mimics strawberry or blueberry jam.
Myrcene (The Heavy): Provides the sedative, musky sweetness that gives the smoke a heavy, satisfying lung feel.
Flavor Notes:
The Aroma: It smells of sugary fruit, vanilla cake batter, and faint diesel. It is soft, sweet, and inviting.
The Smoke: Creamy and smooth. It tastes of berry pastries, powdered sugar, and a hint of tropical fruit (which translates to the pineapple notes seen in Granny Candy).
Strain Effects: The Warm Hug
Based on its parents, W. Runtz Muffin is designed for comfort.
The Experience
The Onset: A gentle, happy euphoria that lifts the mood immediately. It lacks the racy edge of a pure Sativa.
The Body: The Blueberry Muffin genetics provide a warm, relaxing body buzz that is perfect for untying knots in the shoulders.
The Vibe: It is a "Cozy" strain. It makes you want to curl up with a blanket and snacks.
The Munchies: Given the lineage, this is a top-tier appetite stimulant.
Best For: Relaxing evenings, recovering from stress, watching movies, and dessert smoke.
Breeding Legacy: The Mother of Granny Candy
The primary reason we know about W. Runtz Muffin is its role in creating Granny Candy.
The Cross: Mountaintop Mint (Spearmint/Frost) x W. Runtz Muffin (Berry/Dough).
The Result: The Muffin genetics softened the Mint, turning it into a "Hard Candy" smell (Strawberry/Pineapple) rather than a "Toothpaste" smell.
The Vigor: It also passed down the stable growth structure of the Blueberry Muffin, ensuring that Granny Candy yields well and finishes fast (early October).
Final Verdict: The Secret Ingredient
W. Runtz Muffin is the secret sauce in Humboldt’s 2024 lineup. It acts as the bridge between the old-school "Bakery" terpenes and the new-school "Candy" terpenes. While you may have to hunt for a cut or wait for a seed drop to grow it yourself, you can taste its influence in every puff of Granny Candy. It is the genetic proof that Runtz and Muffins are a match made in heaven.
You should choose W. Runtz Muffin (or its offspring) if:
You love Dessert/Pastry profiles.
You want Runtz flavor without the low yield.
You enjoy relaxing, euphoric highs.
You are a breeder looking for unique terpene donors.
