Double Runtz Strain

Double Runtz Strain: When One Runtz Isn't Enough

The Double Runtz strain is exactly what the name promises — a cross of one Runtz line with another, bred to push the candy even further. Crack a jar and it's grape, tropical taffy and creamy citrus up front, with a pungent gas note underneath that keeps it from tasting like a bag of sweets. The high leans relaxed and euphoric, and the numbers run high: producers list it anywhere from the mid-20s to over 30% THC. If sweet-and-gassy is your lane, our THCA flower collection has a few close cousins in stock.

Here's the catch — nobody agrees on which two Runtz went into it. Weedmaps tags the parents as Black Runtz and Runtz, while 7ACRES, the Canadian producer most closely tied to the name, says Detroit Runtz × Forbidden Runtz. Below: both pedigrees and what they share, the real terpene numbers, how the high unfolds, honest potency ranges, how it compares to the rest of the Runtz family, how to grow it and how to judge a bag.

Double Runtz Strain Genetics & Lineage

• Type: Hybrid on Weedmaps. Most of the people actually growing it call it something heavier — 7ACRES labels it indica, Brite Labs' sun-grown jar says indica, and Northern California's Eyeelle calls it indica-leaning.
• Producer: 7ACRES, a Canadian licensed producer. Weedmaps' own strain description credits 7Acres. Neither 7ACRES nor anyone else we found names an original breeder.
• Ancestry: two versions, covered below — Black Runtz × Runtz, or Detroit Runtz × Forbidden Runtz.
• THC: 24–27% on Spectrum Therapeutics' 7ACRES product page; 25–31% on another 7ACRES retail listing; 27–31.5% on Weedmaps.
• CBD: negligible — 0.05% on one Eyeelle batch; 7ACRES lists 0–3%.
• Aliases: Doble Runtz (Weedmaps; We Grow's jar) and Double Rntz (7ACRES' Canadian packaging).

Version one: Black Runtz × Runtz

This is the pedigree on Weedmaps' strain page, and it's repeated in the parent tags of US listings from Major Farms, Brite Labs, Eyeelle and Coastal Sun. Runtz is the original Zkittlez × Gelato candy hybrid; Black Runtz is the darker, earthier, more sedating member of the family. Cross them and you'd expect exactly what people describe — candy on top, more body underneath.

Version two: Detroit Runtz × Forbidden Runtz (7ACRES)

7ACRES' packaging — and the Leafly.ca listing for its "Double Rntz" — says Detroit Runtz × Forbidden Runtz, and calls it "a favourite backcross in a line of Gelato and Skittlez crosses." Detroit Runtz is Tiki Madman's Pancakes × Runtz. Forbidden Runtz exists in several versions: Fast Buds and Growers Choice cross Runtz with Forbidden Fruit, while Tiki Madman crosses it with Tropical Zkittlez. 7ACRES doesn't say which one it used.

Why both stories can be true-ish

Here's what the two versions share: both are Runtz crossed with a Runtz descendant, so either way you get a plant that's mostly Zkittlez and Gelato genetics, doubled. Brite Labs' own listing shows both crosses on the same page, and Major Farms adds a third — Forbidden Runtz × Bubblegum Runtz. The honest read is that "Double Runtz" is a name several growers use for their own Runtz-on-Runtz cut. If provenance matters to you, the 7ACRES pedigree is the only one tied to a named producer.

Double Runtz Terpene Profile

Unusually for a strain this young, there's a real number to work with. 7ACRES reports 3.64% total terpenes, led by beta-caryophyllene at 0.75%, myrcene at 0.57% and humulene at 0.41%, with 1.91% spread across minor terpenes. Other listings name limonene and linalool without percentages. Caryophyllene is the one with the most research behind it: a 2008 PNAS study identified beta-caryophyllene as a "dietary cannabinoid" that binds CB2 receptors.

• Caryophyllene: The pepper and spice behind the "gas" people taste on the exhale. It's the lead terpene on 7ACRES' numbers.
• Myrcene: Earthy and herbal, and the terpene most often linked with a heavier, body-forward feel — a fit for a strain most producers call indica-leaning.
• Humulene: Woody and dry, the same terpene found in hops. It rounds off the sweetness.
• Limonene and linalool: Listed by Major Farms, Brite Labs and Leafly.ca without numbers — likely where the citrus brightness and the soft floral calm come from.

One outlier: a Coastal Sun batch listed α-bisabolol, camphene and 3-carene as its lead terpenes. That's a good reminder that two jars with the same name can be different cuts.

Appearance

Weedmaps describes "vibrant, crystal-coated buds with purple and green hues," and Major Farms' listing calls them dense, frosty green-and-purple buds under a heavy coat of white trichomes. Strain guides add tangerine-to-copper pistils and greens that run from lime to deep forest, with plum-colored bracts showing up when late-flower nights run cool. Expect tight, golf-ball nugs rather than fluffy spears — it's a Gelato-family structure.

Aroma and Flavor

Double Runtz smells like the candy aisle with a gas leak. Weedmaps' write-up describes sweet grape and citrus over "pungent gassy undertones," and a flavor of sugary candy, tropical fruit and creamy citrus with a smooth, classic Runtz finish. 7ACRES' own tasting notes are shorter: gas and fruit, with hints of grape and candy.

• Grape candy: the most consistent note across every listing.
• Tropical taffy and creamy gelato: Major Farms describes "sweet fruit taffy, tropical candy, and creamy vanilla gelato."
• Gas: Brite Labs and Eyeelle both compare the taste to "grape soda mixed with diesel fuel."
• Berry, citrus and earth: the remaining flavor tags on Weedmaps' US listings.

If you've had Grape Runtz or Grape Gas, you're in the right neighborhood — Double Runtz sits somewhere between the two.

Recreational Effects

Double Runtz is a wind-down strain with a good mood attached. On Weedmaps, where it averages 4.6 from 13 written reviews, the community "leans heavily toward relaxed effects with a euphoric cerebral lift." Here's what people report:

• Relaxed: the headline effect — loose shoulders, a settled body.
• Euphoric: a happy, giggly head rather than a racy one.
• Uplifted and clear-minded: Major Farms and Weedmaps both note it doesn't fog you out at a normal dose.
• Heavier at high doses: strain guides warn that couchlock is possible if you keep going.

How the high unfolds: onset, peak and duration

• First few minutes: a fast, cheerful head lift.
• 20–30 minutes: the peak — euphoric and loose, with the body relaxation building.
• 90–150 minutes: a slow settle into calm. Those timings come from a strain guide, not a lab, and your dose and tolerance change them.

Because the body side builds as it goes, Double Runtz works best in the evening or on a day with nothing left to do.

How Strong Is Double Runtz?

Strong — but the published range is wide enough that the label on your jar matters more than the strain name. The numbers we found:

• 7ACRES: 24–27% THC on one retail page, 25–31% on another.
• Weedmaps strain page: 27–31.5%, with individual listings from 24.81% up to 37.46%.
• US batches: Coastal Sun 27%, Eyeelle 24.8%, Major Farms 24% (another Major Farms batch 20.24%), Brite Labs' sun-grown 16%.

Treat the 37% figure as an outlier. Realistically, a well-grown Double Runtz lands in the mid-to-high 20s, which puts it well above average. New users should go slow.

THCA flower is labeled differently from dispensary flower: the lab reports THCA, which converts to THC when heated, plus a small amount of delta-9 THC. When you compare a batch of Double Runtz against the 16–37% range above, compare total THC on the COA, not the headline number — our guide on how to read a THCA flower COA walks through the math.

Who Grows Double Runtz?

Double Runtz is one of those strains you'll find under a lot of labels. In Canada it's a 7ACRES flower, grown in a hybrid greenhouse on coco fibre, hang-dried and machine-trimmed, according to one retailer's listing. In California, Weedmaps shows it from Coastal Sun (greenhouse), Brite Labs (sun-grown Highland jar), Major Farms, Eyeelle (Northern California, living soil) and We Grow, which spells it "Doble Runtz." Several of those listings carry different pedigrees, which tells you each grower may be running their own cut. Ask which one you're getting.

Double Runtz vs Runtz — What's Actually "Double"?

Original Runtz is one Zkittlez × Gelato hybrid. Double Runtz crosses Runtz back into another Runtz line, so the Zkittlez candy and Gelato cream get concentrated. In practice, people describe it as sweeter and gassier than plain Runtz, and a little heavier in the body — which lines up with the Black Runtz or Detroit Runtz parent pulling it toward indica.

Double Runtz vs Similar Strains

• vs Runtz: the base. Runtz is balanced candy-fruit; Double Runtz adds more grape, more gas and more body.
• vs Black Runtz: one listed parent. Black Runtz is earthier and more sedating; Double Runtz keeps more of the bright candy on top.
• vs Detroit Runtz: 7ACRES' listed parent. Detroit Runtz brings a bakery-sweet Pancakes side; Double Runtz reads more grape-and-gas.
• vs White Runtz and Pink Runtz: lighter, fruitier family members with less gas and less weight.
• vs Grape Runtz: the closest flavor twin — grape candy forward — but Double Runtz has more fuel in the finish.
• vs Super Runtz: another "more Runtz" name in the same candy lane.
• vs Super Boof: our featured in-stock pick, and honestly not a twin. Both are sweet fruit with gas and both hit hard, but Super Boof doesn't carry the creamy, grape-candy Runtz finish. If dessert-candy is what you're after, our Lemon Cherry Gelato is the Gelato-side option on our shelf.

Who Double Runtz Is (and Isn't) For

Good fit: evening smokers, candy-and-gas flavor fans, experienced users who want potency, and anyone collecting the Runtz family.

Poor fit: brand-new users (the THC runs high), anyone who needs to stay sharp and productive, and people chasing a bright, energetic daytime high. For sweet fruit and gas with real potency on our shelf, Super Boof is the pick, from $65 for a half ounce.

How to Use Double Runtz THCA Flower — and How Much

THCA has to be heated to do anything. Raw, it isn't intoxicating; heat converts it to THC (decarboxylation), which is why the method matters as much as the strain.

• Smoking (joint, pipe, bong): the fastest onset. Take one or two small hits, then wait 10–15 minutes before deciding on more.
• Dry-herb vaporizer: a good way to taste the grape and candy before the gas takes over. Around 350–380°F keeps the sweet notes bright; 390–410°F brings out the pepper and fuel.
• Pre-rolls: the no-prep option — see our THCA pre-rolls.
• Homemade edibles: decarb the flower first. Edibles take 30–120 minutes to kick in and last far longer, so start low and wait the full two hours.

How much? New or occasional users: one small puff, then wait 15–30 minutes — this one runs strong. Regular users usually find two or three hits gives the full relaxed, euphoric arc. You can always add more; you can't take it back.

Medicinal Benefits

There's very little data here, and we'd rather say so than pad it. These are uses consumers report, not established clinical outcomes, and individual response varies with dose, tolerance and chemotype.

• Stress and unwinding: the most common theme in Weedmaps reviews, consistent with the relaxed headline effect.
• Anxiety: one Weedmaps reviewer reported help with anxiety alongside body relaxation. One review isn't a trend, and high-THC strains can make anxiety worse.
• Body tension: the myrcene-and-caryophyllene profile and indica-leaning effect are why some people reach for it at night.

Nothing here is medical advice, and nothing on this page is intended to diagnose, treat, cure or prevent any disease. If you take prescription medication or have a health condition, talk to your doctor before using any cannabis product.

Side Effects and Cautions

• Dry mouth and dry eyes — the usual THC complaints; no strain-specific data contradicts them.
• Couchlock and drowsiness — likely at higher doses, given the indica lean.
• Anxiety or racing thoughts — possible with any 25%+ flower if you overdo it.

Is Double Runtz good for sleep? It can help you wind down, especially later in the session, but it isn't marketed as a knockout strain. Don't drive after using it, and talk to your doctor first if you take prescription medication, are pregnant or nursing, or have a heart condition.

Is Double Runtz Top Shelf? How to Judge a Good Bag

• Ask which cut it is. 7ACRES' Detroit Runtz × Forbidden Runtz is the only documented version; other jars may be a different cross under the same name.
• A current third-party COA naming the lab, with THCA, delta-9 and total THC. Treat 35%+ claims without paperwork as marketing. Ours are on the lab results page.
• Candy and gas. Real Double Runtz has grape candy over fuel. Sweet with no gas — or gas with no candy — suggests a different cut.
• Dense, frosty buds with green and purple hues and a heavy trichome coat.
• A proper cure — hay or grass smell means it was rushed, and the candy notes are the first thing to go.

Growing Double Runtz

Weedmaps rates Double Runtz a moderate grow. Seeds and clone sources aren't well documented, so most growers start from whatever Runtz-on-Runtz cut they can find.

• Flowering: about 8–10 weeks per Weedmaps. Strain guides say the candy aroma gets loud around week 5 and trichomes go mostly cloudy around week 8.
• Yield: roughly 400–550 g/m² indoors and 450–700 g per plant outdoors, per Weedmaps.
• Climate: 72–80°F in veg and 65–70°F nights in late bloom. Those cooler nights are what bring out the purple.
• Humidity: keep it around 45–55% in flower — dense Gelato-family buds are prone to mold.
• Outdoors: medium height indoors, taller in warm, Mediterranean-style climates; plan for an early-to-mid-October harvest in temperate zones.

Is Double Runtz THCA Flower Legal?

Under the 2018 Farm Bill, hemp is federally legal when it contains no more than 0.3% delta-9 THC on a dry-weight basis — see the USDA hemp program. THCA flower is sold under that rule. State laws differ and are changing, so check your state before you order. And whatever the label says, THCA flower will show up on a drug test — heated, it is THC.

Frequently Asked Questions

Is Double Runtz indica or sativa?

It's a hybrid on Weedmaps, but most producers — 7ACRES, Brite Labs and Eyeelle — sell it as indica or indica-leaning. Expect a relaxed, euphoric high that gets heavier with dose.

What is Double Runtz a cross of?

Sources disagree. Weedmaps lists Black Runtz × Runtz; 7ACRES, the producer most tied to the name, says Detroit Runtz × Forbidden Runtz. Either way it's Runtz crossed with a Runtz descendant.

Who breeds Double Runtz?

No original breeder is documented. 7ACRES, a Canadian producer, is the name most associated with it, and US growers like Coastal Sun, Brite Labs, Major Farms and Eyeelle sell their own versions.

How strong is Double Runtz?

7ACRES lists 24–27% and 25–31% THC, Weedmaps 27–31.5%, and individual US batches range from 16% to 37%. Most well-grown jars land in the mid-to-high 20s.

What does Double Runtz taste like?

Grape candy, tropical taffy and creamy citrus over a pungent gas finish. Two California growers compare it to grape soda mixed with diesel fuel.

What are the effects of Double Runtz?

Weedmaps reviewers describe relaxed effects with a euphoric, clear-minded lift; Major Farms lists euphoric, relaxed and uplifted. Higher doses can lead to couchlock.

What terpenes are in Double Runtz?

7ACRES reports 3.64% total terpenes, led by beta-caryophyllene (0.75%), myrcene (0.57%) and humulene (0.41%). Other listings add limonene and linalool.

What's the difference between Double Runtz and Runtz?

Runtz is Zkittlez × Gelato. Double Runtz crosses Runtz with another Runtz line, so it's sweeter, gassier and usually heavier in the body.

Is Double Runtz good for sleep?

It's better for winding down than for knocking out. The indica lean builds through the session, so it fits evenings.

Yes — Weedmaps lists Doble Runtz as an alias, and 7ACRES' Canadian jars spell it Double Rntz.

How long does Double Runtz take to flower?

About 8–10 weeks per Weedmaps, with yields around 400–550 g/m² indoors.

Where can I buy Double Runtz THCA flower online?
