Watermelon Zkittles is a feminized hybrid, 55% indica and 45% sativa, that crosses Watermelon with The Original Z, with tropical fruit, sweet and berry aromas and a fruity watermelon and grape taste. Barney’s Farm, which sells it as Watermelon Z, lists THC at 28%, and Leafly’s strain data puts it at about 24%. It flowers in about 9 to 10 weeks.
History & lineage
Watermelon Zkittles is Barney’s Farm’s cross of Watermelon and The Original Z, the strain first known as Zkittlez; Barney’s now sells it under the name Watermelon Z, and Leafly lists it the same way.
The Original Z is said to be a mix of Grape Ape and Grapefruit crossed with another undisclosed strain, and it came to market in the 2010s. Leafly credits the growers working as Terp Hogz, with 3rd Gen Family’s Brandon Parker, for popularizing it, and a 2016 Ganjapreneur report named 3rd Gen Family and Terp Hogz as its breeders.
Aroma & flavour
Expect sweet tropical fruit and berry on the nose and a fruity, watermelon and grape taste, the profile Barney’s Farm gives. Leafly users most often report sweet and tropical flavours, followed by berry, citrus and flowery, and Leafly’s lab data lists limonene as the most abundant terpene, followed by caryophyllene and myrcene. Our guide to cannabis terpenes explains what those compounds add to a smell.
Effects, as users report them
These are Leafly users’ reports for Watermelon Z, as Leafly lists this strain, most common first, from a fairly small number of reviews. Leafly describes its effects as mostly calming, with a high that may set in quickly, and Barney’s Farm describes them as uplifting, euphoric and calming. Dry mouth is the downside mentioned most, then dry eyes and headaches; a few users report dizziness or paranoia. Effects vary with the person and the dose, so if you are new to cannabis, start with a small amount.
Growing Watermelon Zkittles
Watermelon Zkittles is a feminized photoperiod plant: it keeps growing leaves until the light drops to 12 hours a day indoors, or until the days shorten outdoors. Barney’s Farm gives 63 days of flowering on its data sheet and 63 to 70 days in its grow notes, about 9 to 10 weeks, with an outdoor harvest in the third to fourth week of September in the Northern Hemisphere.
It is rated an easy grow. Barney’s Farm gives a height of 120 to 140 cm (about 3.9 to 4.6 ft) indoors and 150 to 200 cm (about 4.9 to 6.6 ft) outdoors, around 500–600 g/m² (about 1.6–2.0 oz/ft²) indoors and up to 1,000 g (about 35 oz) per plant outdoors. It describes towering colas packed with buds that hang from every branch, so plan on support for heavy branches, keep air moving through the canopy in late flower, and judge when to harvest by the trichomes rather than the calendar. The fruity smell builds through flowering; our guide to controlling grow smell covers the options.
