A note on the numbers in this article: harvest dates, flowering times and yields are ranges, not promises. They 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 →

What is Zkittlez?

Zkittlez (also searched as "Zkittles" or "Skittles strain") is a fruity, mostly indica variety named after the candy because of its sweet aroma. Seed companies each build their own version, so the genetics change from one breeder to the next. The Zkittlez lines we sell are listed above, and the feminized version is bred by our own team in Quebec.

Flavour, aroma and effects

Zkittlez is grown mainly for its taste. The feminized version leans on grape and grapefruit, the autoflower on grape and apple, and Watermelon Zkittlez adds watermelon and candy. Expect a sweet, fruity smell that gets stronger in late flowering.

People usually describe the high as calming and relaxed in the body, with a bright, cheerful start. That is typical of a mostly indica strain, but effects differ from person to person and with the dose.

How to grow Zkittlez

  • Size: plants stay compact to medium, which suits tents and smaller spaces.
  • Photoperiod version: flowers in 7 to 8 weeks. Outdoors in Canada, harvest is usually late September to early October.
  • Autoflower versions: they flower on their own schedule, about 70 to 75 days from seed to harvest, with no light change needed.
  • Humidity: keep air moving and humidity steady in late flower. Dense, fruity buds can grow mould if the air is stagnant.
  • Training: gentle low-stress training and an even canopy help every bud site get light.
  • Yield: expect roughly 400 to 550 g/m² indoors, depending on the version and your setup.
