GMO Strain (GMO Cookies)

Many cannabis strains are named after their flavor, and some are named after their effects. The indica dominant GMO cannabis strain is named after its smell. Short for “Garlic Mushroom and Onions,” it doesn’t sound like this strain would be so well-loved. However, its breeders knew what they were doing when they created this potent and flavorful strain.  

Sativa/Indica % Indoor Yield Outdoor Yield Flowering Period
10% / 90% 16oz/ m2 21oz/ plant 10 weeks indoors, mid-October outdoors.

GMO Cookies, aka Garlic Cookies, is a potent mix of the two very popular strains, Girl Scout Cookies (GSC) and Chemdog. The names’ garlic cookies’ and ‘GMO cookies’ replaced GMO as dispensaries avoided anything remotely similar to ‘genetically modified.’ Even with the name, this indica dominant strain was praised as one of the best new strains in 2017. It delivers a savory taste while remaining only moderately difficult to grow.

This strain can be very potent. Tests by the breeder Divine Genetics say THC levels on the GMO strain can reach 30%, which is quite high for an indica. There’s a reason many say this strain is for use by experienced stoners.  Surprisingly, its perfect blend of sativa and indica with just enough THC provides a pleasant body high, without the debilitating couchlock. This makes the GMO strain a great daytime weed, one quality that makes it stand out from other indica strains.

The cannabis strain GMO works quickly, offering immediate benefits for those suffering from mental stress or physical pain. Even though this is an Indica with high levels of THC, there’s still a head high that leaves you feeling stoned, but not so stoned that you aren’t functional. For many, this is the definition of a great indica as it provides relief without being overwhelming.  

If you’re looking for a good mood,
this Indica is one of the best. It causes a sense of happiness combined with
creativity. Some writers say this strain helps cure writers’ block by melting
away stress, stimulating creativity, and helping them stay focused. 

Although this strain won’t knock you out, you should be prepared to relax. The GMO cannabis strain is potent, so it is best not to drive or do anything too physical until you had time to recoup.


This strain’s name comes from its aroma, which resembles a rich earthy blend of raw garlic, mushroom, and onions. Its other name, GMO cookies, refers to the heavy garlic influence on its Girl Scout Cookies lineage. This garlic influence comes from its Chemdawg parent, which has a diesel-like scent. In the GMO cannabis strain, this fuel scent reduces to plum, and coffee notes, which mixes with GSC’s sweet earthiness to somewhat smell like garlic and onions.


Once lit, the flavors will surprise you. There’s no hint of garlic– instead, you experience the cookie side, which is pleasantly sweet with a rich coffee-like earthiness at the end. The flavor is immediately recognized as the popular Girl Scout Cookie strain, although it started off smelling like garlic.
