What is the Runtz strain?
Runtz is an evenly balanced hybrid of Zkittlez and Gelato that came out of the California scene through the Runtz crew and Cookies, and Leafly named it 2020 Strain of the Year. It is known for a sweet, fruity candy aroma, frosty, tight buds and THC reported from 19% to 29% in AllBud's profile. Feminized Runtz plants are photoperiod, so they flower once the light schedule drops to 12 hours, usually finishing in 8 to 10 weeks indoors and in mid-October outdoors.
AllBud and Leafly list Runtz as 50/50; MSNL's feminized listing leans slightly indica at 55/45.
Runtz is named for the candy it smells like, a sweet, fruity blend from both parents.

Where does the Runtz strain come from?
Runtz was created in California by crossing Zkittlez with Gelato, and it was brought to market by the Runtz crew working alongside Cookies around 2017. Zkittlez contributes the sweet, mixed-fruit candy smell and Gelato adds the creamy depth, dense structure and heavy frost. The name is a nod to the fruit candy the buds are said to smell like.
Runtz spread fast through dispensaries and pop culture, and in December 2020 Leafly named it Strain of the Year, citing its terpene profile, quality and soaring demand. It has since become a parent of a whole family, including White Runtz, Pink Runtz and Guava Runtz, and seed makers now offer it as feminized photoperiod and autoflower seed.
How is feminized Runtz different from Runtz Autoflower?
Feminized Runtz is the photoperiod plant, so you control when it flowers and how big it gets. You can veg it as long as you like, train it into a wide SCROG canopy and flip to 12/12 when it fills the space, then flower for 8 to 10 weeks. The autoflower adds ruderalis genetics, stays smaller and runs on a fixed clock from seed, which is quicker but leaves less room to shape the plant or push yield.
Choose photoperiod for size and selection. Feminized Runtz also lets you take clones from a favorite plant before flowering, which an autoflower does not allow.
How does Runtz taste, and how does it feel?
Aroma and flavor
Runtz tastes like a handful of fruit candy: sweet berry and tropical fruit with a creamy finish, plus a little spice or gas on some phenotypes.

- Sweet cream
- Spice
- Gas
Terpenes
- Caryophyllene
- Peppery warmth under the sugar

Runtz terpene order changes between growers and phenotypes, but caryophyllene and limonene show up most.
Reported effects
Runtz is mostly reported as a happy, euphoric hybrid that starts with an uplifted mood and slides into calm body relaxation. AllBud users also note the munchies and, at higher doses, a sleepy, couch-bound finish, so many people save it for the evening.
- Euphoric
- Uplifted
- Relaxed
- Hungry
- Sleepy
Runtz users mention dry mouth, a foggy head for some, and heavy couch-lock if they overdo it.
Runtz effect reports here come from AllBud reviews and Leafly's strain coverage. Responses vary with dose and tolerance, so nothing here is medical advice.
How do you grow Runtz seeds?
Feminized Runtz seeds are easy to moderate to grow: veg them until they fill your space, top and train for an even canopy, switch to 12/12, and flower for 8 to 10 weeks while keeping the smell and humidity under control.
- Germinate3–7 days
Pop Runtz seeds in a moist paper towel or starter plug and move them once the taproot is about 1 cm.
- Vegetate4–8 weeks indoors
Top Runtz once or twice and spread it with LST or a SCROG net; a longer veg pays off in yield.
- Flower8–10 weeks
After the 12/12 flip, Runtz stretches moderately and stacks dense, frosty buds by mid-bloom.
- HarvestDay ~56–70 indoors · mid-Oct outdoors
Check trichomes with a loupe and cut when most are cloudy for the fullest candy flavor.
Grow tips for Runtz
- Fill a SCROG before the flip. Photoperiod Runtz lets you veg until the net is about 70% full, which evens out the dense colas under the light.
- Watch dense buds for mold. Runtz buds are tight and sticky; keep humidity near 45% in late bloom and defoliate inside the canopy.
- Carbon filter early. The sweet candy smell turns strong from week 4 of flower and carries well beyond the tent.
- Clone your best plant. Runtz shows some phenotype spread; take cuttings in veg so you can keep the plant with the best nose.
- Dry and jar it slowly. Hang Runtz around 18–20 °C (64–68 °F) and about 60% humidity for 10–14 days, then store it in sealed jars to protect the candy aroma.

Runtz strain FAQ
Is Runtz indica or sativa?
Runtz is a balanced hybrid. AllBud and Leafly list it at about 50% indica and 50% sativa, while some seed listings put the feminized version at 55% indica. Its effects usually start uplifting and end relaxing.
What strains make Runtz?
Runtz is a cross of Zkittlez and Gelato, with Gelato #33 most often named as the Gelato cut. Zkittlez brings the fruity candy smell and Gelato adds the creamy flavor and dense, frosty buds.
Who created Runtz?
Runtz was created in California by the Runtz crew, and it rose to fame through a partnership with Cookies around 2017. Leafly later named it the 2020 Strain of the Year.
How much THC does Runtz have?
Runtz is a high-THC strain. AllBud reports an average range of 19% to 29%, and feminized seed listings typically say up to about 24%. Results depend on the phenotype, the grow and harvest timing.
How long does Runtz take to flower?
Feminized Runtz flowers in about 8 to 10 weeks indoors once the lights are set to 12 hours on and 12 off. Outdoor Runtz in the Northern Hemisphere is usually ready around mid-October.
How much does Runtz yield?
Feminized Runtz is listed at about 400 to 500 g per square meter indoors. Because it is a photoperiod plant, a longer veg and SCROG training can push it toward the top of that range.
What is the difference between Runtz feminized and Runtz autoflower?
Feminized Runtz is photoperiod: it needs a 12/12 light switch to flower, can be vegged and cloned, and grows larger. Runtz Autoflower flowers on its own from seed, stays more compact and finishes faster, usually with a smaller yield.
What does Runtz taste like?
Runtz tastes sweet and fruity, much like the candy it is named after, with berry and tropical notes, a creamy finish from Gelato and sometimes a hint of spice or gas.
