GMO is a clone-only indica-dominant hybrid from Mamiko Seeds' Chem Cookies line, a cross of Chemdawg D and the Forum cut of GSC. Michigan cultivator SkunkMasterFlex grew out the seeds, found the keeper and gave it its name. Skunk House Genetics carries the cut today.
The plant won first place Indica at the 2017 High Times Midwest Cup. At the same event it took second place for solventless concentrates, and High Times put it in its Top Ten varieties for 2018.
David Mamiko's Cookies Collection
David Mamiko of Mamiko Seeds released his first Cookies Collection in 2013. It held about 20 crosses built on the Forum cut of GSC, with several Chemdawg partners among them: Chem D, Chem 4, Snowdawg and a Chemdawg Sister.
The Chem D cross first went out as D-Cookies. Mamiko later renamed it Chem Cookies, the name the seed line still carries. Production of the original Chem Cookies seeds ended in 2014, and Mamiko announced a restock for 2019.
Mamiko has since built a regular seed version around the original clone. It backcrosses Chem Cookies to an F1 male called Birds of Fire, itself GMO × Breathwork, so growers can start the line from seed instead of a cutting.
How SkunkMasterFlex found and named GMO
SkunkMasterFlex took Mamiko's Chem D cross, selected one plant and propagated it as a clone. That cut is the one grown and traded as GMO, and 710 Labs lists it as clone-only with Mamiko Seeds as breeder.
The name has two meanings. At the time, the Girl Scouts of the USA were taking criticism over genetically modified ingredients in their cookies. SkunkMasterFlex also felt the plant grew as if it had been genetically modified.
The cut now circulates under several names. Leafly lists the flower as GMO Cookies, with Garlic Cookies and GMO Garlic Cookies as alternate names. Clone sellers label it the Skunkmasterflex cut from Skunk House Genetics.
Skunk House Genetics is known for GMO and for its Burger line. It releases regular seeds for pheno hunters and breeders, with recent drops including Stoner's Delight, Strawbercots, DiscoFries and Champagne Patties.
A long flower and a heavy stretch
GMO is not a quick plant. Mamiko puts flowering at 70–74 days, while clone sellers carrying the Skunkmasterflex cut list 11–12 weeks. Leafly lists 8–9 weeks with short to medium height and rates the grow as hard.
Stretch is the main thing growers plan around. The Skunkmasterflex cut can triple in height after the flip, and the Forum GSC side helps give the branches enough structure to carry the Chem D weight.
Mamiko describes a fairly complete plant with strong potency. It also flags the intersex tendency common to Chem genetics. Its regular seed version builds enormous colas on an indica-dominant frame, yielding 500–600 g/m² indoors and finishing outdoors in October.
Why hash makers want the cut
GMO made its name in the wash. Clone sellers call it a dump truck, with fresh frozen returns of 5%–6% or more. Its large, sandy trichome heads come off easily in ice water, and the resin stays stable and greasy.
710 Labs calls GMO a solventless staple, and Mamiko's seed line is described as a champion in dry hash, ice-o-lator and rosin. Potency runs high too. Leafly averages 28% THC, and clone sellers report tests above 30%.
Punch Extracts presses the cut as GMO live rosin. Its Weedmaps catalog lists a 1g Tier 3 fresh press and a Silver Tier cold cure badder, and Weedmaps files Punch's GMO live rosin vape under GMO Cookies, with Chemdog and GSC as parents.
GMO as a parent
The clone has become a common breeding parent. Mamiko's own Birds of Fire male carries GMO, and Washington breeder In House Genetics crossed it with Slurricane to make Garlicane, an indica-dominant hybrid that tests around 23% THC on Leafly.
In House then took the family a step further. It crossed Garlicane back to Slurricane #23 to create Garlic Storm, a feminized release that flowers in about 8–9 weeks indoors.
Leafly users describe GMO Cookies as relaxing and euphoric, with a heavy body feel at higher amounts. The flavor leans garlic and pepper, the trait behind the Garlic Cookies nickname.
