Why you should buy GMO Cookies Auto seeds
If you’re chasing a heavy-hitting autoflower that delivers funky, nose-wrinkling flavor and an old-school punch wrapped in next-gen simplicity, GMO Cookies Auto is the one. With up to 27% THC, it’s not here to mess around. This strain brings everything you'd expect from a classic GMO cross: think diesel-drenched garlic funk, thick resin crusts, and that signature knockout effect, combined with the ease and speed of autoflowering genetics. Beginner growers, you’re in luck. This one practically runs on autopilot.
Expect rock-solid buds, a distinct aroma that’s impossible to ignore, and a mellow-to-couchlock experience that hits hard and fades just right. Add to that her monster yields and high fungal resistance, and you’ve got a serious contender for your next personal favorite.
If you’ve got the time and want to push yields to the limit, the GMO Cookies photoperiod version brings the full grower’s toolkit to the table.
Strain Overview
Origin
GMO Cookies Auto takes the stanky brilliance of GMO Cookies (also known as Garlic Cookies) and folds in a robust Ruderalis to make it autoflowering and beginner-friendly. GMO itself is a legendary mix of Chemdawg and Girl Scout Cookies, bred for raw power and flavor so loud it should come with a warning label. The addition of Ruderalis gives it that automatic behavior, meaning no need to mess with light schedules. Just plant, feed, and prepare for funky fireworks.
Effects & Flavors
This strain doesn’t tiptoe in. It marches in, boots muddy, ready to chill you out in all the right ways. Euphoric and uplifting on the front end, GMO Cookies Auto eventually settles into a deep, peaceful body calm. Great for stress, sleep, and switching your brain off after a long day.
As for the flavor? It’s straight-up loud. Diesel-soaked garlic, skunky spice, and a strange sweetness underneath it all that somehow ties everything together. If you’re into savory, you’ll be in heaven. If not... you’ll still respect it.
THC & CBD Levels
With a THC level topping out at 27%, GMO Cookies Auto sits firmly in high-potency territory. This is not one for the faint of heart or low-tolerance tokers. CBD isn’t a player here. It’s all about that pure, potent THC-led experience. Expect a long-lasting high and heavy body effects.
Terpenes
The terp profile reads like a greatest hits of knockout weed. Caryophyllene adds that peppery kick and relaxing depth. Humulene and Myrcene bring the herbal, earthy undertones. Limonene gives the mood a lift, and Pinene balances things with a subtle freshness. Together, they support both the flavor and the effects in all the best ways.
Growing GMO Cookies Auto Seeds
Grow Difficulty
This is an easy-going plant with serious potential. Ideal for beginners who want to harvest like a pro without overthinking every detail. It’s resilient, tough, and can handle a range of conditions thanks to its high resistance to mold and mildew. Keep it fed, keep it lit, and it’ll reward you without drama.
Indoor vs. Outdoor Growing
Indoors, GMO Cookies Auto stays compact and manageable. It’s perfect for tents or grow rooms with limited height (35 inch to 47 inch). Outdoors, she stretches just a bit more, up to 59 inch, but still stays under control. She’s happy in greenhouses, open gardens, or sunny balconies in Mediterranean, temperate, or arid climates. Just give her decent airflow and a good spot, and she’ll do her thing.
Flowering Time & Yield
This girl finishes in 70 to 75 days from germination, which is slightly longer than some autos, but worth the wait. Indoors, yields can reach a chunky 1.6–2 oz per square feet. Outdoors, she’s capable of pushing out 21.2–24.7 oz per plant if conditions are dialed in. That’s a serious haul for an autoflower, especially one with this kind of quality.
