Probably named after the kaleidoscopic candy, Skittles, this strain promises a rainbow of fruity and sweet delights worthy of the moniker...
What Are Feminized Zkittlez Seeds?
Feminized Zkittlez seeds are female weed seeds that produce the award-winning Grape Ape x Grapefruit indica hybrid famous for its tropical candy-fruit flavor, 20–30% THC, and gorgeous purple-hued buds delivering relaxed, uplifted effects. These photoperiod plants are beginner-friendly, reaching a medium height with heavy yields after a flowering time of 8–10 weeks.
Also known as Skittlez, Skittles, Zkittles, and The Original Z, feminized Zkittlez seeds grow into female bud-bearing cannabis plants with virtually no males, so you don’t spend time sexing plants or worrying about seeded buds.
Why Grow Feminized Zkittlez Seeds?
Grow feminized Zkittlez seeds if you want:
- Easy-growing indica hybrid plants that suit small spaces, thriving indoors or out.
- Generous yields of potent, flavor-packed Zkittlez weed with top-shelf bag appeal.
- Uplifting and relaxing indica effects with maximum THC.
- Award-winning genetics to grow your own dispensary-grade weed at home.
Zkittlez Strain Genetics, Origins & the Original Z Name
Zkittlez is an indica-dominant strain first bred in the 2010s in Northern California from Grape Ape and Grapefruit with an undisclosed third parent. Grape Ape contributes vivid purple colors and candy fruit terpenes, while Grapefruit adds bright sativa lift and a citrus edge. As one of the first candy dessert strains to gain popularity, Zkittlez built its reputation on competition.
The strain took first place in both the ‘Indica’ category at the 2015 High Times Cannabis Cup and the 2016 Emerald Cup. With these cup-winning qualities, Zkittlez has since become a parent of newer crosses including the famous Runtz family with descendants like Runtz Auto, Moonbow Auto, Animal Runtz, and Galactic Runtz.
Zkittlez Strain Aroma, Flavor & Terpenes
Zkittlez is famous for its candy-like profile built on grape, citrus, and tropical fruit, with a grounding earthy undertone. Caryophyllene, humulene, and linalool are its main terpenes, bringing hints of pepper, herbs and florals to all that sweetness.
You’ll notice it in the tent first. The aroma grows stronger each week of flower, reaching its peak right before harvest, so plan for odor control if you grow indoors. After a proper cure, the buds open with a burst of sugary fruit and a tangy citrus bite. On the inhale, expect a smooth and sweet fruitiness that evolves into a pleasant zest on the exhale.
Zkittlez THC Levels & Effects
Zkittlez reaches 20–30% THC with low CBD (0–1%), which puts it in very high potency territory. The effects typically kick off with a euphoric, mood-boosting lift before calming relaxation gradually settles into the body. At higher doses, Zkittlez weed may bring dry mouth or dry eyes, so anyone with low tolerance should start with a small amount and go slowly.
Zkittlez Feminized Seeds: Flowering Time & Yield
Zkittlez feminized seeds grow into medium-height plants that flower in 8–10 weeks, putting a full run at roughly about 16–20 weeks from seed. With a heavy yield rating, these Zkittles seeds are high yield cannabis seeds, though how much you actually harvest depends on plant care, nutrition, and your skill as a grower.
As a photoperiod plant, Zkittlez stays in veg until you flip the lights to 12/12 indoors, while outdoor plants go into flower as the days shorten. In the Northern Hemisphere, Zkittlez seeds go in the ground in late April or early May once frost risk has passed and come down in early October, though your local climate can shift that window.
| Growing Zkittlez Indoors | Growing Zkittlez Outdoors | |
| Plant size | More compact, fits a tent with training | Grows taller and larger |
| Flowering trigger | The light flip to 12 hours on and 12 hours off | Shortening days with longer darkness periods at night |
| Timeline | 8–10 weeks in flower, about 16–20 weeks seed to harvest | Plant late April–early May, harvest early October |
| Best for | Medium to large tents, SCROG or LST setups, growers who want more control | Warm, sunny climates, long summers with a frost-free fall, growers who want a more hands-off grow |
How to Grow Zkittlez Strain Seeds
- Keep the environment stable. Zkittlez does best in warm conditions without big swings in temperature or humidity. Outdoors, it suits Mediterranean-style climates with long, dry summers.
- Start seeds right. Follow our germination guide to get seeds cracked and taproots showing before moving them into their first containers.
- Stay on top of airflow and humidity. Dense buds raise the risk of mold during flower. Hold humidity at 50–60% in veg and 40–50% in flower, keep temperatures between 65°F and 80°F, and run fans so air keeps moving through the canopy.
- Train for an even canopy. Topping or FIMing early in veg, followed by LST or a ScrOG net, spreads the plant out so more bud sites sit under full light. LST and ScrOG are especially useful in a small tent where vertical space runs out fast.
- Feed gradually. Bring nutrient strength up in steps rather than all at once, and back off the feed if leaf tips start to burn. Use a nitrogen-rich feed in veg and slowly switch over to a phosphorus and potassium-rich feed in flower.
- Cool the nights to bring out color. In the last 2 weeks of flower, let nighttime temps run about 10°F cooler than daytime to encourage purple hues. Not every phenotype will color up, though so treat it like a bonus. Watch humidity carefully when you do this.
- Harvest by the trichomes. Chop when most trichomes have gone from clear to cloudy and some amber is starting to show.
- Cure slowly. After shopping and drying, a 2–4 week jar cure keeps that candy-fruit aroma intact.
What Are the Best Zkittlez Seeds for Your Grow?
Zkittlez feminized seeds suit indoor growers who want full control over veg time, a full-season outdoor grow, and growers who want the biggest plants and heaviest yields.

Zkittlez Seeds FAQs
What Is the Best Grow Medium for Zkittlez Auto Seeds?
A light, airy soil mix is the best medium for Zkittlez Auto seeds because it’s forgiving, holds enough nutrients to carry seedlings through the first few weeks, and drains well enough to protect the roots. Look for a mix with perlite and avoid heavily amended “hot” soils, since autos are easy to overfeed.
If you want faster growth and tighter control over feeding, coco is a strong second choice, though it needs light feeding from early on and more frequent watering. Hydro can push growth even further but leaves less room for error, so it suits experienced growers best.
How Should You Store Zkittlez Buds After Curing?
Keep cured buds in airtight glass jars in a cool, dark place, ideally around 60–65°F with humidity near 58–62%. Light, heat, and air break down terpenes over time, so good storage is what keeps that gorgeous candy-fruit aroma and flavor strong for months rather than weeks. Two-way humidity packs make it easier to hold the jars in that range.
What Strains Are Crossed With Zkittlez?
Zkittlez has been crossed with dozens of strains, and its best-known offspring is Runtz, a cross with Gelato that became one of the most popular strains of the late 2010s. Other notable crosses include Moonbow, Rainbow Glue, and White Runtz. Breeders often use Zkittlez mainly to pass on its sweet, fruit-candy terpene profile.
