Runtz is an uncommon strain with an uncommon taste. You’ll recognize the candy-like flavor that gave it its name; however, it also features solid THC levels, with percentages ranging from 18% to a sky-high 29%. As a hybrid strain, Runtz provides the best of both worlds with both a euphoric head high and a bone-deep body buzz.

Sativa/Indica % Indoor Yield Outdoor Yield Flowering Period
50% / 50% 14-16 ounces per square meter up to 18 ounces per plant 7 – 9 weeks indoors, mid-October outdoors.

Medical users appreciate the Runtz OG strain, too. The body buzz helps stimulate relaxation and offers an escape from the pain of daily life. Chronic stress and anxiety also melt away, allowing sufferers to escape from their worries for a while. After the strain has kept users high for hours, it winds down into a sweet, dreamy sleep.

There are several Runtz phenotypes out there, but the indica/sativa blend is usually within the 40/60 range in either direction. The most common is an even 50/50 split between the two. The Runtz strain origin is a cross between Zkittlez and Gelato (although some say these are the genetics of the Pink Runtz strain).

Runtz Strain Effects

The effects of the Runtz strain happen almost immediately. Even as the candy aftertaste is wearing off, the intense, euphoric head high starts coming on. Within minutes of the first toke, most users report euphoric, giggling feelings of joy. It’s a creative high, but not quite enough that you’ll want to leave the house. This head high can last for hours, so have craft activities or movies prepared in advance.

The body high kicks in about fifteen minutes after the head high. It usually starts in the back of the head and melts down the spine, before expanding to the limbs and leaving fingers tingling. It’s an excellent strain for evening use. Once the body high hits, you’ll likely find yourself sitting in one place, thinking creative thoughts, or watching your favorite movies.


If you’ve opened up a container of candy Runtz and gotten a puff of sugar to the face, you have a solid understanding of the cannabis strain’s scent. It’s sweet, fruity, and mild, just like candy.


The flavor is just like the smell, sweet, fruity, and a little creamy. The aftertaste is particularly sugary. You might notice a hint of berry in particular with the Pink Runtz strain.

Adverse reactions

The most common side effects of Runtz use are dry eyes and mouth. However, because of the intense THC level in this strain, users who dive in too quickly occasionally report anxiety or paranoia from use. These symptoms coincide with users underestimating Runtz. Pacing dosage and not taking too much of the candy-flavored kush at once can help mitigate these side effects and keep everything cool.


Runtz Strain Medical

Like many strains with a serious body high, those using the strain therapeutically have great things to say about Runtz.

The sativa genetics are obvious when starting your Runtz strain grow. It’s an aggressive upwards grower that doesn’t naturally branch off. For growers interested in training it to grow out instead of up, it reacts well to high-stress training techniques. In this case, the Screen of Green growing technique can help gardeners make the most of their Runtz plants.

To help Runtz plants thrive, be ready to fertilize and water. Runtz plants grow quickly, meaning they’ll need more nutrients than compact varieties. In particular, don’t be afraid to supplement extra nitrogen. Just keep an eye on the leaves to make sure they aren’t suffering from nutrient burn.

Flowering Time


Runtz handles indoor growing well. Look for plants to be ready for harvest in 7-9 weeks on average. When growing inside, the Runtz strain produces 14-16 ounces of quality bud per square meter, depending on training techniques.


When growing Runtz outside, growers can expect their harvest to be ready by mid-October in the northern hemisphere. In quality conditions, each Runtz plant can produce up to 18 ounces of bud.
