GMO Rootbeer strain guide
GMO Rootbeer is an indica-leaning hybrid that crosses the garlicky GMO with a strain called Root Beer. True to its name, people describe a sweet root beer and vanilla smell, often with a savoury, gassy streak from the GMO side. It's known for high THC and a calm, relaxed feel.
Where does GMO Rootbeer come from?
GMO Rootbeer comes from Freeborn Selections, a Mendocino breeding outfit, and is credited to breeders Skunktek and Mean Gene. Two strain databases agree on the cross: GMO Cookies, the strain better known as GMO, with Freeborn's own Root Beer.
Root Beer's own background is murkier. One strain database traces it to a probable Headband cross with older Kush lines, but several of those links are marked uncertain. Another database gives a different pairing, GMO with Vanilla Crème, so you may see that listed too. The GMO and Root Beer cross is the one most sources give.
What does GMO Rootbeer smell and taste like?
Root beer is the headline: sugary soda and creamy vanilla, with spice in the background. Most batches also carry some of GMO's character, so expect dank, diesel or even garlic notes under the sweetness. One published review of a single grow went further, picking up mustard and brine, so it can vary a lot by cut.
One strain database lists myrcene as the top terpene, followed by limonene and caryophyllene. Myrcene suits the earthy, dank base, limonene adds brightness and caryophyllene a peppery bite that fits the spice. The flavour leans sweet, creamy and a little tea-like.
GMO Rootbeer effects: what people report
People mostly describe GMO Rootbeer as calming. One strain database's reviews describe a drowsy, euphoric start that drifts toward sleepy, while another database's users often mention feeling giggly, focused and hungry along the way. A few people say it felt more upbeat than they expected for an indica-leaning strain.
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 anxious or getting a headache. One reviewer also found the smoke harsh.
How strong is GMO Rootbeer?
This is a very high-THC strain. One strain database lists it around 26% THC and another database gives 27% to 33%, with very little CBD. That puts it near the top of what flower usually reaches.
If you're new to it, start with a small amount and give it time before having more. The numbers for your batch are on the label, and our guide to reading cannabis labels explains what they mean.
Buying GMO Rootbeer in Canada
Watch for look-alike names. Crosses that use GMO Rootbeer as a parent, such as Frosted Rootbeer, are sold under their own names and can even be labelled sativa-leaning. If the label lists genetics, check that it's the GMO and Root Beer cross.
Check the THC and CBD numbers, any terpenes listed and the packaging date, since fresher flower keeps more of that soda-shop smell.
GMO Rootbeer vs GMO
GMO is one of GMO Rootbeer's parents, and both are heavy, high-THC hybrids with a relaxed reputation. The big difference is the smell. GMO is famously savoury, with garlic and onion front and centre, while GMO Rootbeer puts sweet root beer and vanilla on top and keeps the garlic and gas underneath. If you love the savoury funk, GMO is the purer version. If you want that funk softened with something sweet, try GMO Rootbeer.
Strains like GMO Rootbeer
If you like GMO Rootbeer, these are the closest matches:
- GMO: the parent, with the full garlic and onion smell and none of the soda sweetness.
- Garlic Breath: another GMO cross, savoury and peppery with a relaxed, sleepy reputation.
- Garlic Cocktail: GMO crossed with Mimosa, so garlic with a sour orange top instead of root beer.
