Forbidden Runtz Strain (2024)

It’s hard to say what’s more popular about the Forbidden Runtz strain. It may be its powerful highs and rich flavors, or it could be its name, considering the number of variations sharing this moniker. Despite lacking originality in the strain-name department, the genetics between cultivars are slightly more varied (though you can trace them all back to Runtz).

While this means a wider selection for the avid cannabis consumer – who bred it best? – it makes it trickier to confirm some finer details. Still, our research team has worked hard to ensure all Forbidden Runtz strain info is accurate and up to date. As time goes by, we may uncover more about the origins of this strain and the layers of terpenes that make up its unique flavor and scent. But for now, let’s get into what we currently know.

Forbidden Runtz strain genetic

It’s unclear who created the Forbidden Runtz cannabis strain first. The most prominent versions come from Fast Buds, Growers Choice, and Tiki Madman. Each offers a unique version of the strain, all starting with Runtz. An offspring of Zkittlez and Gelato, Runtz offers an irresistible blend of balance, potency, and flavor, making it a favorite among breeders and consumers.

Fast Buds and Growers Choice both confirm breeding Runtz with Forbidden Fruit in their versions. Originally from Chameleon Extracts, Forbidden Fruit is an indica-leaning cross of Cherry Pie and Tangie. Renowned for its unique terpene profile, many hail it as one of the best-tasting hybrids around. Its THC content can exceed 20%, making its potency just as impressive. Fast Buds also added their autoflowering genetics in their breeding process, developing a Forbidden Runtz autoflower that won Best Novelty Auto strain at the 2022 Growdiaries Poty Cup.

According to Tiki Madman, their version crosses Runtz with Tropical Zkittlez. Sources debate whether Tropical Zkittlez comes from a cross between Zkittlez and Tropicana Cookies or Zkittles and an unknown strain. Some believe Tropical Zkittlez and Zkittlez are the same thing. Either way, this hybrid inherits that Grape Ape x Grapefruit combo synonymous with delectable flavors, potent THC levels, and an easy-to-grow nature.

Info suggests there could be a version that combines Runtz with Forbidden Zkittles. However, when compiling this Forbidden Runtz strain review, there wasn’t enough information to verify this.

Is Forbidden Runtz strain indica or sativa?

The Forbidden Runtz weed strain leans indica, though the exact ratio will depend on your cultivar. The Fast Buds version displays a 65:35 indica dominance, while the Growers Choice version has a slightly higher 70:30 indica lean. The exact ratio of the Tiki Madman version is unconfirmed, but its genetics suggest it likely falls within this range.

Growing Forbidden Runtz strain

Each version of the Forbidden Runtz marijuana strain comes from a lineage of strong genetics with desirable growing habits. Forbidden Runtz itself continues this trend with an easy-to-grow nature that both beginner growers and veterans will love.

This hardy strain naturally resists pests and mold, can withstand various climates, and grows well indoors and outdoors. Depending on your version, it’ll reach heights of 35-60 inches indoors and 50-80 inches outside. Growers recommend using the screen of green method (SCROG) to support the weighty branches that develop. They also say it responds well to low-stress training (LST).

These plants may be small compared to many other strains, but the crystal-coated buds they produce release heavy-weight flavors and aromas. The fruit that develops is dense and incredibly sticky to the touch, with spaces between buds, ensuring healthy airflow.

Forbidden Runtz strain flowering time and yield

The Forbidden Runtz marijuana strain has a fairly short flowering time that averages around 8-9 weeks. If you’re growing outdoors, you can expect to harvest around late September to early October in the Northern Hemisphere. Reports suggest that Forbidden Runtz can be a generous yielder with high resin production, especially when conditions are ideal.

Disclaimer: The average yield of any cannabis plant depends on several factors, including the cultivator’s skill, growing conditions, strain genetics, and the plant’s size and health. It also differs between photoperiod and autoflower plants. However, you can use general estimates as a potential yield per plant guideline.

For photoperiod plants, this is 16-64 ounces (450-1814 grams) outdoors and 8-24 ounces (227-680 grams) indoors.

Forbidden Runtz strain autoflowering time and yield

According to Fast Buds, their autoflowering version flowers in roughly 9 weeks and yields 1.5 — 1.8 oz/ft2 indoors and 2–5 oz/plant outdoors.

Forbidden Runtz strain effects

With such well-balanced genes comes a well-balanced high, so you can expect to feel both sativa and indica effects. Due to the high THC levels, the effects come on a few moments after the first hit and packs quite the punch.

Consumers say you’ll first feel a rush of euphoric energy, engulfing you with happiness and spurring creative thought. At the same time, waves of physical calm ripple through your body, easing you into relaxation and allowing you to get lost in your thoughts. Those suffering from depression, anxiety, stress, and migraines say they benefited from the relaxing, tension-easing high this hybrid delivers.

You can expect some side effects, like cottonmouth, red eyes, and hunger. In larger doses, you could experience mild anxiety and couch lock.

How strong is the Forbidden Runtz strain?

Forbidden Runtz falls in the “know what you’re doing” category, so if you’re a beginner smoker, you may want to pace yourself. The Forbidden Runtz strain THC level starts at about 20%, but it can reach 26% to 28%, depending on your version. The CBD content sits at just under 1%.

Forbidden Runtz strain terpenes

While there’s no confirmation on the exact terpenes found in Forbidden Runtz, its terpene profile is clearly loaded to the max. Experts suggest it likely contains myrcene, caryophyllene, a-bisabolol, valencene, and pinene.

Myrcene and caryophyllene contribute musky, earthy tones to the flavor and aroma. A-bisabolol and valencene are responsible for those sweeter notes, and pinene brings that woody pine element.
