It gets harder and harder to find elite marijuana strains that are bred properly, match the strain description, and deliver a potent, fun high. Fortunately, we’ve discovered a banger strain called Seriotica, which is made by Serious Seeds.

Serioitica is a cross between Girl Scout Cookies (GSC) and Mimosa, two of the most popular cannabis strains to come along in the past 20 years. GSC is a combination of OG Kush and Durban Poison that leans slightly Indica. Mimosa smells like the champagne/citrus beverage called a “mimosa,” and is a cross of Purple Punch and Clementine.

These strains get a lot of love because they’re easy to grow, yield big, and their highs are powerful but not debilitating.

Serious Seeds started a breeding project many years ago to combine GSC and Mimosa. In 2021, they sent us a test pack of a GSC/Mimosa cross called Seriotica before they ever released the strain to the public, and we’ve grown several batches of Seriotica seeds since then over a period of four years.

We usually grow several strains at the same time in the same room to see which strains grow best and which ones struggle. The first Seriotica plants were grown with five other strains. Out of all of them, it was the sturdiest, most resilient, highest-yielding, fastest-finishing.

While other strains were having trouble handling accelerated light intensities and feed programs, Seriotica had no problems. It was a fast-grower showing no leaf symptoms or any other defects. It was easy to see that this strain had been properly bred, was vigorous, and will reward a skilled grower.

We top Seriotica several times during a grow phase that lasts 4-5 weeks. It handles topping well, with sturdy branches and an easily-sculpted structure. It’s usually the first strain to develop floral clusters after bloom phase started, and bloom phase stretch is slightly less than double, making this strain a good choice for indoor gardens.

After 22-28 days in bloom phase, floral clusters start emitting scintillating scents whose intensity increases as the buds got bigger and thicker.

Resin glands appear early, creating the frosty leaves you see in the photo accompanying this article. That bud is only 34 days old. When you see that much frost on such a young bud’s large leaves, you know it’s killer cannabis.

Seriotica is remarkably stable and consistent in phenotype traits. I detect two phenotypes, mainly differentiated by their terpenoid scents. All other morphology is uniform.

One phenotype expresses Cookies scent: brown sugar, baked sugar cookies, cookie dough, and mint.

The other pheno expresses Mimosa scent: tangy orange and lime fruit punch, with a twist of fuel and roses.

Now that I’ve grown the strain many times I’ve concluded the differences in scent don’t automatically translate into differences in effects.

For example, Cookies is known as a strong, euphoric but sometimes sedative strain, while Mimosa is a stimulating strain. With Seriotica you get a wide range of effects, depending on when you harvest, not just on bud scents or phenotype.

I recommend incremental harvesting as a generic policy. This means that instead of waiting until the end of bloom phase to harvest all the buds at once, you harvest some earlier, in increments.

With Seriotica, we start harvesting 43-49 days into bloom phase, in part because buds are already thick, extremely dense, loaded with cloudy, collapsing trichomes, displaying a lovely reddish-blue tint that intensifies as bloom phase progresses. Incremental harvesting continues until final chop-chop, usually around 50-55 days in bloom.

The earliest-harvested buds create a very strong, uplifting, visually-enhancing high with delicious taste delivered through my precision Storz & Bickel Mighty+ vaporizer.

Depending on vaporizer temperature, the taste of mimosa, mint, grape, roses, and fruit candy came through from the chunky, gooey buds. These scents are very strong and tantalizing when you open a jar of cured Seriotica.

Buds harvested latest in bloom phase create a strong, long-lasting high with delicious taste, but the high trends more towards what you expect from sedative Girl Scout Cookies when GSC is leaning towards its Kush rather than Durban Poison genotype.

I use cannabis mainly so I can be active while high, so heavy Kush and Indica strains aren’t my favorites. The good news is that even the final incremental cut of Seriotica buds provides an enjoyable and functional high, rather than a disabling high.

The earlier buds are fantastic for doing athletics. The later-harvested buds are great for watching movies, getting a massage, doing yoga, having sex.

The Seriotica high isn’t like other strains, can’t be classified as Indica or Sativa, and is exceptionally entertaining and rewarding. My estimate is that at least 25-27% of the active cannabinoids in these buds is THC, making it quite potent.

The high hits immediately and at first is very strong and body-centered. This feeling goes away after a few minutes and an energized, euphoric high takes its place.

Seriotica buds are thick and tight, but in my test grows, they never developed gray mold (botrytis) even when other strains in the same room did.

The buds cure well and become visually beautiful, with an iridescent azure tint that makes them very attractive to buyers.

Seriotica buds stored in glass jars in the freezer still have the scent and potency of freshly-cured buds, even after many months in storage.

One cool thing is when you leave Seriotica buds in an active vaporizer and a lot of vapor leaks out, it smells like freshly-baked cookies!

Due to the high resin gland percentages, Seriotica is very useful for making ice water hash,  kief, dry sift, and other cannabis concentrates.

The buds are easy to manicure because they’re not leafy. Harvest weight averages 139 grams per indoor plant, which is impressive considering the plants aren’t very tall, averaging about 4.5 feet in height.

One of the best ways to evaluate new strains is to share buds with other professional growers. Everybody I share with loves the Seriotica strain. One grower disappointed by elite cuts of Mimosa and GSC said Seriotica greatly exceeded his expectations, giving him the best of both strains.

The strain is a heavy feeder and needs a large root area. It is mildly attractive rather than repellant to spider mites, whiteflies and aphids, so you have to pay close attention to the leaves during bloom phase to ensure no pests are on them.

Seriotica is one of few new marijuana strains released in the past ten years that we’ve grown multiple times and never been disappointed.

That being said, seed breeders have a hard time maintaining mother and father plants for elite strains. That’s why we always recommend that before you buy marijuana seeds, contact the breeder and ask them about the latest genetic heritage and traits of particular strains you’re interested in.

Unless something bad happens at Serious Seeds so the Seriotica seeds we’ve grown are no longer available but an inferior version has replaced them, you can count on Seriotica to be one of your favorite strains ever.
