We all love Runtz for the candy’s variety of flavors, which is the same type of love you’ll have for this variety too. One of the strain’s biggest perks is its wide variety of fruity flavors that come from its sugar-fueled cross. Runtz Auto is the outcome of crossing Gelato x Zkittlez x Ruderalis for an autoflowering version of one of the most beloved indica dominant hybrids. But don’t worry, this variety doesn’t cut corners when it comes to potency or yields. The strain still easily reaches 20-24% THC and up to 500gr/m². The only difference is you’ll be ready to enjoy the ‘fruits’ of your minimal labor in almost half the time, at just 6-8 weeks.  


One thing about Runtz the candy is that it can be tart and sweet. For Runtz Auto its slightly indica dominant effects are just as balanced. At times, you’ll feel completely relaxed with its uplifting, blissful effects, and sometimes you’ll feel energized and even aroused. Overall, the nearly equal sativa to indica characteristics produce a buzz that’s pleasurable and euphoric. Consumers prefer the strain to relieve pain, stress, and nausea, and to alleviate symptoms of arthritis. Since this variety tends to produce up to 24% THC, you can always count on the variety for an intense and enjoyable high when you need it the most.  


Runtz Autoflower can easily be grown indoors or outdoors, making it versatile for any type of grower too. Keep in mind that the strain will thrive in warm, Mediterranean-like climates. This means that, for most regions, you can prepare for outdoor harvests in June and October with its shorter life cycles of just 6-8 weeks. One reason why growers love the strain is its short stature and ability to conceal it from neighbors or contain it in small spaces. The plants typically grow from 60-100cm (2-3 ft) but pack on the weight to still produce maximized yields of 400-500gr/m². 

Appearance & Aroma

Runtz Auto is nothing short of beautiful as she blooms. The variety dazzles with bright and vibrant greens, with flowers that radiate in shades of deep purple and light lavender. As harvested buds, the nugs are just as pretty, with a golden hue and a heavy coating of icy trichomes. Adding to the strain’s appeal is its overpoweringly delectable aroma. Auto Runtz boasts an eclectic terpene profile that produces a pungent scent of mixed fruit—including sweet and refreshing tropical, citrus, and berry notes you’ll soon crave to taste.   

MSNL Editors Verdict

Let’s get real—Runtz might not be your favorite candy, but Runtz Auto may quickly become your favorite strain. This variety is the real deal from start to finish, with its easy growth, manageable heights, and gorgeous buds that pack on weight, fast.

Tasting Notes
