What is the Guava Runtz strain?
Guava Runtz is a balanced indica-sativa hybrid from the Runtz candy family, sold as feminized seed by Karma Genetics as a cross of Guava Gelato and Pink Runtz. Leafly and Weedmaps also list a Guava × Runtz version credited to the Bay Area's Cookies Fam, so the name covers more than one cross. Karma's version flowers in 8 to 9 weeks with a medium-to-high yield. No breeder has published a tested THC range yet, although its parent strains are usually listed somewhere between about 19% and 30%.
Weedmaps compares Guava Runtz to tropical candy dusted with pepper, like ripe fruit sprinkled with chili-lime seasoning.
Guava Runtz strain specs
Guava Runtz is a new strain with few published numbers. The flowering time and yield rating come from Karma Genetics' listing on SeedFinder. The breeder doesn't publish THC, height or terpene data, so those rows report what Leafly, Weedmaps and the parent strains show instead of guessing.
| Type | Balanced indica-sativa hybrid (no published ratio) |
|---|---|
| Genetics | Guava Gelato × Pink Runtz (Karma Genetics); Guava × Runtz (Cookies Fam version) |
| Bred by | Karma Genetics, as part of its Pink Runtz line shown at Spannabis 2024; a separate Guava × Runtz is credited to Cookies Fam |
| THC | Not published; Weedmaps lists its parent strains at about 19–30% |
| CBD | Not published |
| Main terpenes | Caryophyllene (dominant on Leafly); others not documented |
| Aroma & flavor | Tropical fruit, powdered candy, creamy gelato dough, pepper |
| Reported effects | Happy, giggly, talkative, energetic, then calming (few reports) |
| Seed type | Feminized (female plants), photoperiod |
|---|---|
| Flowering indoors | 8–9 weeks (about 60 days) |
| Outdoor harvest | Not published; an 8–9 week bloom usually means early autumn in the Northern Hemisphere |
| Height | Not published by the breeder |
| Yield | Medium to high (breeder rating; no figure given) |
| Difficulty | Moderate; few grow reports so far |
| Best methods | Topping and LST for an even canopy; SCROG in tents |
| Climate | Indoors, greenhouse, or outdoors in a warm, dry autumn |
Where does the Guava Runtz strain come from?
The feminized Guava Runtz documented on SeedFinder comes from Karma Genetics, which crossed a Guava Gelato mother with Pink Runtz. SeedFinder says the Guava Gelato cut has done well in California and the Netherlands, and that Guava Runtz joined Karma's Pink Runtz line, which the breeder first showed at Spannabis 2024. The background of Pink Runtz itself is marked only as probably Pink Panties × Rainbow Sherbet.
A second Guava Runtz exists. Leafly and Weedmaps list a Guava × Runtz cross credited to the Cookies Fam crew in the Bay Area, pairing a sativa-leaning Guava with Runtz, which is itself Zkittlez × Gelato. Both crosses carry Gelato-family genetics and a tropical-candy profile, but they are not the same plant, and many shops don't say which one they sell. Read any Guava Runtz spec as approximate until more growers report back.
Is Guava Runtz the same as Runtz?
No. Guava Runtz is a newer cross built on Runtz-family genetics, not the original Runtz. Runtz is Zkittlez × Gelato. Guava Runtz adds a guava-flavored parent, Guava Gelato in Karma's version or Guava in the Cookies Fam version, which pushes the flavor toward tropical fruit and pepper and away from the original's plain fruity-candy sweetness.
Check the breeder. Because two crosses share the Guava Runtz name, plant shape, timing and flavor can differ between seed sources.
What does Guava Runtz taste like, and how does it feel?
Aroma and flavor
Guava Runtz tastes like tropical candy: ripe fruit and powdered sugar with a light peppery bite, and Karma's version adds a creamy, doughy gelato note.
- Tropical fruit
- Candy
- Pepper
- Tree fruit
- Creamy dough
Terpenes
- Caryophyllene
- Peppery spice; the dominant terpene on Leafly's profile
Guava Runtz's full terpene profile hasn't been published; caryophyllene is the only terpene Leafly names for it, which fits its peppery flavor.
Reported effects
Guava Runtz users mostly report a happy, giggly, talkative high with some energy at first, while Leafly's overall rating leans calming, so it seems to settle down as it goes. Reports are still few, so expect variation.
- Happy
- Giggly
- Talkative
- Energetic
- Calm
No downsides are well documented for Guava Runtz yet; with parents this strong, start with a small amount to avoid an overwhelming high.
These Guava Runtz effects summarize the limited user reports on Leafly and Weedmaps. Everyone responds differently, and nothing here is medical advice.
How do you grow Guava Runtz seeds?
Guava Runtz feminized seeds grow like a standard photoperiod hybrid: veg the plants until they fill your space, train them for an even canopy, switch to 12/12 and harvest after about 8 to 9 weeks of flowering. Because few grow reports exist, watch your own plants closely and adjust as you go.
- GerminateAbout 1 week
Guava Runtz seeds are feminized, so every healthy seedling should grow into a bud-bearing female.
- Vegetate4–6 weeks indoors
No height is published for Guava Runtz, so start training early and set your veg time once you see how fast your plants grow.
- Flower8–9 weeks
Karma Genetics lists about 60 days of bloom. Resin builds heavily on the small leaves around the buds late in flower.
- HarvestAround day 60 indoors
Go by trichome color rather than the calendar, since the two Guava Runtz crosses may not finish on the same schedule.
Grow tips for Guava Runtz
- Save the sugar trim. Karma describes heavy resin on the leaves of Guava Runtz, so keep the trim for hash or other extracts.
- Leave headroom until you know your plant. With no published Guava Runtz height, top once in veg and keep space above the canopy for the stretch after the flip.
- Dry it slowly. The candy and tropical notes are the point of Guava Runtz, so dry the buds in a cool, dark room over about 10 to 14 days to hold on to them.
- Note which cross you have. Karma's Guava Gelato × Pink Runtz and the Cookies Fam Guava × Runtz may grow differently, so keep a record of your seed source and results.
- Outdoors, choose a warm, sunny spot. SeedFinder lists Guava Runtz for indoor, greenhouse and outdoor growing; outdoors, give it full sun and harvest before long spells of autumn rain.
Is Guava Runtz the right strain for you?
Great pick if you
- Like sweet, tropical, candy-style flavors with a little spice
- Want a new Runtz-family strain that few people grow yet
- Want feminized seeds with an 8–9 week bloom

Think twice if you
- Want a fully documented strain with lab-tested THC numbers
- Need one confirmed pedigree before you buy
- Prefer a classic earthy or gassy indica
- Need a plant with a known, compact size for a very small space
Guava Runtz strain FAQ
Is Guava Runtz indica or sativa?
Guava Runtz is listed as a balanced hybrid with both indica and sativa genetics, but no breeder publishes an exact ratio. Weedmaps describes the Cookies Fam version as a sativa-leaning Guava crossed with the balanced Runtz.
What are the parents of Guava Runtz?

Who bred Guava Runtz?
Karma Genetics bred the Guava Gelato × Pink Runtz version as part of its Pink Runtz line, which it first showed at Spannabis 2024. A separate Guava × Runtz is credited to the Bay Area's Cookies Fam crew.
How much THC does Guava Runtz have?
No breeder or strain database has published a tested THC range for Guava Runtz yet. Its parents are strong: Weedmaps lists Guava Gelato at 19–25%, Pink Runtz at 23–27% and Runtz at 21–30%, so high THC is likely but not confirmed.
How long does Guava Runtz take to flower?
Karma Genetics lists Guava Runtz at 8 to 9 weeks of flowering, about 60 days, after the lights are switched to 12/12. No outdoor harvest date has been published yet.

Guava Runtz tastes like tropical candy with a peppery edge. Leafly lists tropical, pepper and tree-fruit flavors, and Karma describes aromas ranging from powdered candy to creamy, doughy gelato.
How much does Guava Runtz yield?
Karma Genetics rates the Guava Runtz yield as medium to high but doesn't give a figure. Your result will depend on light intensity, training and how long you veg the plants.
Is there a Guava Runtz autoflower?
Yes. Fast Buds sells a Guava Runtz Auto, listed at 10–14 weeks from seed, as a separate product. These feminized Guava Runtz seeds are photoperiod plants that need a 12/12 light schedule to flower.
Is Guava Runts the same as Guava Runtz?
Yes. Guava Runts is a common misspelling of Guava Runtz, and both spellings point to the same Runtz-family hybrid. Search results under either name may still mix the Karma Genetics and Cookies Fam crosses.
