Effects: Runtz generates superior euphoric effect with a lingering happy and cheerful high.

The body high usually starts in the back part of the head before spreading down the spine and tingling the fingers.

What to Expect While Growing Runtz Cannabis? 

The Runtz cannabis strain is relatively easy to grow both indoors and outdoors, although growers may face certain challenges with nutrition, training, and managing the tall plants. 

Grown indoors, Runtz plants produce around 15 ounces of weed, or only 1-2 ounces of weed per square foot. Outdoors, the yield will be slightly bigger, or around 18 ounces on average per plant. 

Once you start growing your own Runtz plants, it may feel like the sativa genetics are dominating. This strain is indeed a towering monster, and it can reach as much as six feet in height, which might be a tricky moment for new growers. If you are not sure whether you can handle such a big plant in an indoor setting, and have the option to grow outdoors, opt for outdoors. Otherwise, high-stress training can always help you tame down the Runtz. 

Considering the amount of feed that Runtz strains require during growth, it might not be the biggest yield in your life. Collecting around 15 ounces of weed per plant is slightly below the average. But importantly, you will be getting high-quality cannabis with indisputable therapeutic and recreational benefits. And in the end, that’s all that counts. 

Which Training Methods to Apply for the Runtz Strain? 

Runtz plants are not prone to branch off, so a preferred training technique in this case would be Screen of Green. Scrogging can help you manipulate the Runtz strain to grow outward instead of upward. 

Runtz is also a cultivar that tends to form dense foliage, which may prevent the free passage of air and light through all parts of the plant. Topping and pruning this strain can be helpful to reduce the excess of green and promote equal bud growth on all parts of the specimen. 

How to Nutrient Feed Runtz Weed? 

Runtz is a ferocious eater, even though it does not produce as much weed for the food it consumes. Plants grow quickly and demand more nutrients than most other strains. Therefore, be ready to feed and water your Runtz plants most regularly. 

The main advice is to add extra Nitrogen during the veg phase, but also monitor the plants for any signs of nutrient burn. The most prominent sign for nutrient burn is browning and yellowing on the leaves tips and margins, and also stunted growth, so watch out for that. 

In order to thrive, Runtz plants also need well-draining, nutrient-rich soil with pH parameters between 6.0 and 6.5. You can use both organic feeds or bottled formulas that are administered to the plants according to a specific schedule. 

What Is the Optimal Environment for This Strain? 

Runtz wants warm climates with daily temperatures ranging between 70-80°F and slightly cooler night temperatures

The strain generally responds well to powerful indoor lighting, including LED and high-pressure sodium (HPS) lamps. Outdoors, it’s important to protect plants during exceptionally hot periods of the day by providing them shade

In a grow room, keep humidity at moderate levels, such as between 40-50% during veg phase, and then slightly decrease when the plants enter flowering, to 35-40%. 

Keep the room properly ventilated to prevent issues such as powdery mildew or pests infestations. Runtz is sensitive to aphids, spider mites, and fungus, so regularly scanning the plants for infestations is recommended. Always work with clean gardening tools and apply organic pest solutions if you notice bugs that are not supposed to be there. 

Where Can You Purchase Runz Seeds? 

While your local dispensary might not have an available pack of Runtz seeds, this strain can be supplied from various cannabis seed banks around. Runtz cultivars can be found either auto or feminized and some of the seed banks to check include Royal Queen Seeds, Seedsman, Crop King Seeds, ILGM, Herbies, MSNL Seeds, and more.
