GMO Zkittlez strain guide

GMO Zkittlez is an indica-leaning hybrid from Ethos Genetics that pairs the funky GMO Cookies with a Zkittlez and OG Kush hybrid. Expect chem and fuel on the nose with a sour-sweet edge, and a heavy, calm feel that most people save for late in the day. It's also sold as GMO Z or GMOZ.

Where does GMO Zkittlez come from?

GMO Zkittlez was bred by Ethos Genetics. Sources agree on the cross: GMO Cookies, better known as GMO, on one side, and a hybrid of The Original Z (Zkittlez) and OG Kush on the other.

That gives it a mix of very different parents: GMO's garlic and chem funk, Zkittlez's fruity candy and OG Kush's fuel and pine. One strain database notes it was only ever released as regular seeds, and that growers see a couple of different plant shapes from the same pack, so cuts can vary.

What does GMO Zkittlez smell and taste like?

Most descriptions lean toward the GMO side: chemical, fuel and earthy notes, with some people picking up tea or even an ammonia-like sharpness. The Zkittlez side shows up as a sour-sweet, slightly floral or candy edge underneath.

Taste reviews are split. Some people enjoy the funk and others really don't, which is common with GMO crosses. We couldn't find a published terpene breakdown for GMO Zkittlez, so we've left that blank rather than guess from its parents.

GMO Zkittlez effects: what people report

People most often describe GMO Zkittlez as relaxed, sleepy and tingly. Reviewers call it heavy and calming rather than energizing, and many say it suits late nights over daytime plans.

These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints, and some people mention feeling paranoid.

How strong is GMO Zkittlez?

GMO Zkittlez has a reputation for being very strong. One strain database's breeder listing says THC can go past 25%, and one Ethos dispensary listing shows a batch at about 32% total THCA. There aren't many published results, so treat that as a rough picture.

It isn't a good first pick for beginners. If you try it, start with a small amount and wait before having more. If THCA on a label is new to you, our guide to THCA vs THC explains the difference.

Buying GMO Zkittlez in Canada

Watch the name: GMO Zkittlez, GMO Z and GMOZ usually refer to the same Ethos cross, but other producers sell different GMO and Zkittlez crosses under similar names. If the label lists genetics, check that they match.

Look at the THC and CBD numbers and the packaging date, since that strong chem smell fades as flower ages.

GMO Zkittlez vs GMO

GMO is one of GMO Zkittlez's parents, and the family link is easy to smell: both lead with savoury funk and fuel, and both are described as heavy and relaxing. GMO is the pure garlic-and-onion version, while GMO Zkittlez softens it a little with a sour-sweet, candy edge from its Zkittlez side. Both sit at the strong end of the THC range. If you want the classic savoury hit, go with GMO. If you'd like a touch of sweetness in the funk, try GMO Zkittlez.
