These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

About Runtz
Genetics & strain profile
Runtz Autoflower is the candy-flavoured West Coast hybrid of Zkittlez and Gelato #33 in an autoflowering plant. It is an even 50% indica, 50% sativa mix with THC reaching up to 29% — unusually strong for an autoflower — and yet it is easy to grow, even for beginners, which is why it carries our beginner-friendly and compact, balcony-friendly badges. Five reviews so far, all five stars. One grower wrote that it “changed my mind on autos”, with a “massive yield off one plant” and a smooth smoke he likes for daytime; another in southern Ontario put it outside on June 1 alongside our Northern Lights auto and had both “doing amazing”; a third had four of five seeds germinate and all four plants reach 120 cm, “like they said”, and called it very easy with minimal training.
How Runtz Autoflower grows
Because it is an autoflower, Runtz flowers on its own schedule without a change in light hours — 18 to 20 hours of light from seed to harvest indoors, or outdoors once the frost risk is past. It is ready 7 to 9 weeks after flowering starts, about 11 to 12 weeks from seed, with up to 350 g/m² indoors and up to 250 g per plant outdoors; the reviewer who got a “massive yield” from one plant shows what good light and a big pot can do. The plant stays compact, around 120 cm, which suits tents of all sizes and balconies. Start it in its final pot, keep the feeding light and use low-stress training only — autoflowers do not recover from heavy pruning in time. The Gelato buds are dense, so keep temperature and humidity steady in the last weeks to prevent mould and mildew; one reviewer noted his yield improved as soon as he replaced a faulty pH meter, a reminder that autos punish nutrient mistakes quickly.
Taste, aroma and effect
Sweet and fruity, with the berry and citrus candy of Zkittlez and a rich, creamy side from Gelato #33. The high is strong and well rounded: uplifting and euphoric in the head with a calming body effect — reviewers use it in the daytime, but at up to 29% THC it will put a newer user on the couch, so start small.

Incredible plant! Changed my mind on Auto’ with this. Massive yield off one plant, good smooth smoke great for daytime use.

Been using your seeds for years and this year I got a total winner times two.
The Runtz and the Norther Lights (both auto) are doing amazing outdoors. Put out June 1 in southern Ontario.
Thanks

I can finally write a review since I grew and am currently smoking this strain.. to start 4 seed out of five germinated for me all 4 plants grew to 120cm tall like they said. I know I would have got a better yield but my ph tester was finished and giving me wrong readings after I got a new one my buds and yield got better. At the end I got close to 3 ounces per plant.
Very nice smell and the beautiful purple and blueish colour of the buds honestly I thought they were some sexy looking plants
