Oreoz S1 is the cleanest way to put the Oreoz family in your own garden. Candies Seed Co took the original Oreoz, the 3rd Coast Genetics cross of Cookies and Cream x Secret Weapon, and selfed it: the plant was induced to produce its own pollen, which was then used to fertilize its own flowers. The result is an S1, a first-generation self-cross where both the mother and the father are the same Oreoz plant.
Because no outside genetics enter the picture, an S1 stays focused on the parent’s own traits. Seeds come out feminized by nature, and the population leans toward the dark dessert gas profile that made Oreoz famous. Like any S1, it still recombines what the parent carries, so expect some spread between plants and plenty of room to hunt for a keeper that matches your taste.
Within the Collector Series VOL.1 by Candies Seed Co, Oreoz is one of five clearly named parental routes, branded as the Dark Dessert Gas line. The breeder calls this S1 the baseline reference of the family: the pack to grow if you want to know what Oreoz itself brings before exploring the four crosses built on top of it.
Flowering takes 8–9 weeks, the breeder rates yield as Medium–High and potency as Very High, and the recommended moment is clearly night. The Oreoz parent is known for chunky, dense buds that can go green-to-purple, and in some cases nearly black, late in bloom.
Flavor, Effects, and the Oreoz Signature
The aroma opens on chocolate cookie and roasted coffee, the darker side of dessert. Behind it sits a diesel and earthy funk that keeps the profile from turning sugary. Creamy vanilla touches and a hint of tobacco round out the exhale, giving the smoke a rich, heavy, full-bodied finish.
Candies Seed Co describes this profile as built for depth, density and lasting impact, and that is the point of selfing Oreoz: rather than diluting it with a guest parent, the S1 doubles down on the cookie, cocoa and coffee core. Growers who love heavy, dark dessert terps will recognize the family character from the first rub of a stem.
The experience is pitched for the end of the day. Oreoz is commonly associated with a relaxed, euphoric body feel that slides into heaviness as the session goes on, often with a solid case of the munchies. With a Very High breeder potency rating, this is a cross to approach slowly and save for evenings with nothing left on the schedule.
Think of it as the dark-roast of the collection: weighty, slow and long-lasting. Experienced consumers who prefer serious presence over bright, buzzy highs will find exactly that here.

FAQ
What does S1 mean in Oreoz S1?
S1 stands for a first-generation selfed cross. Candies Seed Co induced an Oreoz plant to produce pollen and used it on the same plant, so both parents are Oreoz. The seeds are feminized and stay focused on the Oreoz profile, while still showing some variation between plants.
What is the genetic background of Oreoz?
Oreoz is the 3rd Coast Genetics cross of Cookies and Cream x Secret Weapon. It is an indica-dominant hybrid known for chocolate cookie, coffee and diesel aromas and dense, chunky buds.
How does Oreoz S1 fit into the Collector Series VOL.1?
It is the reference cross of the Oreoz line, branded Dark Dessert Gas. The other four Oreoz crosses from Candies Seed Co pair a guest parent with Oreoz, while the S1 shows what Oreoz brings on its own.
How long does Oreoz S1 take to flower?
The breeder gives a flowering time of 8–9 weeks, with a Medium–High yield rating.
How strong is Oreoz S1?
Candies Seed Co rates its potency as Very High and recommends it for night. No lab THC figure is published for this cross.
How should I grow Oreoz S1 indoors?
Top early and spread the canopy with LST or a SCROG net, since Oreoz can stretch noticeably in early flower. Keep humidity in check late in bloom because the buds grow dense, and run a good carbon filter for the cookie-diesel aroma.
