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 →
Taste & Aroma Profile




Sweet and fruity, like watermelon and candy — “an awesome Skittles candy smell” on the best phenotype — with subtle earthy undertones.
About Watermelon Zkittlez
Genetics & strain profile
Watermelon Zkittlez Autoflower is Watermelon Zkittlez crossed with Ruderalis: a 60% indica, 40% sativa autoflower with 25 to 26% THC that carries our beginner-friendly and compact, balcony-friendly badges. Its seven reviews average 4.3 out of 5 and they are a fair portrait. The good: “buds were thick and heavy with white resin”, “I love its fruity flavour and its big, easy-to-trim buds”, a Cape Breton grower who “for the first time in a very long time had buds actually finish… pretty mold resistant as well… looks exactly like the pic”, and a Southern Ontario grower on his second year of QCS autos in 15-gallon pots. The honest notes: two growers saw variation between plants — one plant smellier and stronger than its sisters, two seedlings with calcium trouble — and one grower, used to photoperiod plants, disliked that an auto flowers when it decides to and found the yield low. Our seeds are guaranteed.
How Watermelon Zkittlez Autoflower grows
Because it is an autoflower, it flowers on its own schedule without a change in light hours, and that is the thing to accept before you plant it: it will start stacking when it is ready — early June for the Ontario grower, from a May start — not when you are. It takes 70 to 75 days from seed and stays compact in a tent, though outdoors in a big pot one grower had plants of about 5 feet. Indoors it gives 450 to 550 g/m²; outdoors 180 to 250 g per plant, which matches the reviewer who weighed about 150 g from a 5-foot plant in a pot. Keep temperature and humidity steady to prevent mould and mildew in the dense buds, plant in the final pot, feed at half strength with a little extra calcium and magnesium — two seedlings in one review showed calcium deficiency — and keep training to the low-stress kind. Germination has been reliable: 100% for one grower.
Taste, aroma and effect
Sweet and fruity, like watermelon and candy — “an awesome Skittles candy smell” on the best phenotype — with subtle earthy undertones. The high is strong, both uplifting and relaxing: the indica side calms the body and the sativa side lifts the head, and at 25 to 26% THC it is one of the stronger autoflowers here, so start small. For the photoperiod Zkittlez line, see Zkittlez; for other candy-sweet autoflowers, Gelato Autoflower and Girl Scout Cookies Autoflower; one reviewer’s bonus seeds, Grape Skunk, “produced monsters” beside it.

Watermelon Zkittlez were sent to us by QCS as a replacement for another strain that did not germinate. 100% germination rate on wet paper towel for this strain. Plants grew only about 5 feet tall, which is great for smaller spaces (esp. in a pot on a balcony), but the buds were thick and heavy with white resin. The yield was about 150g per plant only, but it is a nice strong high. The only 1 star I take off is because of the very strong skunky smell that permeated my place while drying it. It was so strong that you could smell it all over our apartment building. After it dried, the aroma changed into more subdued fruity smell. Overall not bad strain at all, but wouldn't probably grow again due to the strong smell.

J’adore sa saveur fruitée et ses gros bud facile à trimer a garder dans la liste des bonnes sortes

The genetics don't seem to be stable, two of the seeds exhibited severe calcium issues while the others seemed fine. My problem with these seeds are that they flower on their own, as in, they are autos which means the general size of the plant was not under my control. The yields were also low. The grape skunk that came with it produced monsters though, because they are photos.

Easy to start flowering before the wanted time. Also, genetic not stable because I have one plant really smelly (awesome skittle/candy smell) stronger and a bit different than the 2 others. Same grow tent and same time.

Well here we are at the start of another harvest. Southern Ontario outdoor. Once again doing QSC FV's in 15 gallon pots with nearly the exact same results as last year. This Watermelon zkittlez started stacking in early June already and probably could have used a bit more time out. We figured we'd better take it before the neighborhood kids decided to take it for us. Even know this is a bit early it sure is nice. Big fat buds with lots of crystal and the smoke is smooth. The only reason I took a star off is it was a bit of a pain in the butt to trim lot of small leaf around the buds but well worth it. If I keep giving everything 5 stars know one will believe me hahaha.
