Do-Si-Dos is an Archive Seed Bank cultivar created in 2016 by crossing OG Kush Breath (OGKB) with Face Off OG. It runs roughly 70% indica, can reach 30% THC, and delivers a brief hard-hitting euphoria followed by pronounced body heaviness.
It also happens to be one half of Moonbow, which means Do-Si-Dos sits directly behind two of our own releases. If you have wondered where the weight in Cherry Limetta comes from, given how bright the nose is, this is the answer — the effect is inherited from a plant that smells nothing like it.

The Parents
OG Kush Breath
OGKB is an unconfirmed descendant of Girl Scout Cookies, and it brings floral, earthy aromatics along with mood lift and body relaxation.
It is also responsible for the distinctive growth habit that runs through this family — OGKB phenotypes tend toward slow, squat, dense structure that is not always easy to work with.
Face Off OG
Face Off OG is a heavy-hitting OG Kush phenotype selected in California. It contributes structural vigour, a stronger root system and a sharp, fuel-forward gas profile.
Where OGKB is floral and soft, Face Off OG is aggressive. The combination is what gives Do-Si-Dos both its complexity and its weight.
| Parent | Character | Contribution |
|---|---|---|
| OG Kush Breath | Floral, earthy, GSC-derived | Aroma complexity, mood lift |
| Face Off OG | Sharp, fuel-forward OG | Vigour, root system, gas, sedation |
| Do-Si-Dos | The cross | Complex nose, heavy body effect |

Archive Seed Bank and the Moonbow Connection
This is where Do-Si-Dos becomes directly relevant to our catalogue.
Archive created Do-Si-Dos in 2016. They then crossed it with Zkittlez to make Moonbow — a deliberate attempt to keep Zkittlez terpenes while fixing its weak yields and awkward structure using Do-Si-Dos vigour and potency.
Moonbow #112 is a selected phenotype from that project, and Moonbow 112 IX is a later intercross. Both of our Moonbow selections descend directly from Do-Si-Dos.
| Step | Cross | Purpose |
|---|---|---|
| 1 | OGKB × Face Off OG | Do-Si-Dos — potency and vigour |
| 2 | Zkittlez × Do-Si-Dos | Moonbow — Z flavour, better agronomy |
| 3 | Moonbow #112 selection | Resin density, candy aromatics |
| 4 | Moonbow 112 IX | Stabilised intercross |
| 5 | Lost Leaf pheno hunt | Cherry Limetta and Lou Bega |
Cherry Limetta and Lou Bega both came out of that final step, and the weight in both of them traces back to this plant. Our Zkittlez guide covers the other half of the Moonbow equation.
The OGKB Line
OG Kush Breath deserves more attention than it usually gets. It is an unconfirmed GSC descendant that produced an entire family of slow, squat, intensely resinous plants.
Growers either love OGKB genetics or refuse to run them. The flower is exceptional and the plants test patience — long vegetative periods, modest yields and a habit of sulking if pushed.
Do-Si-Dos is arguably the most successful attempt at keeping what OGKB does well while removing the reasons commercial growers avoid it.
What It Feels Like
Do-Si-Dos is not subtle. Reports consistently describe a short, hard euphoric onset followed by a pronounced body high and a mellow, sedated mood.
Many people describe it as borderline sleepy. It is an evening cultivar in the fullest sense, and not one to reach for if you have anything left to do.
| Aspect | Character |
|---|---|
| Onset | Fast, briefly euphoric |
| Body | Heavy, pronounced |
| Head | Mellow, quiet |
| Duration | Long |
| Suits | Evening, sleep, experienced consumers |
Growing Notes
OGKB-derived plants have a reputation for being slow and squat. Face Off OG improves that considerably, but this is still not a beginner cultivar.
- Expect slow vegetative growth. OGKB genetics take their time.
- Train early. Squat structure benefits from canopy work.
- Watch density in late flower. Heavy, tight buds need airflow.
- Feed carefully. This family is sensitive to being pushed.
Our plant training guide covers canopy management for squat plants, and the troubleshooting guide helps with the sensitivity.
Why Archive Made It
Archive Seed Bank have a consistent approach: take something with an exceptional quality and cross it with something that fixes its weaknesses.
Do-Si-Dos was that project applied to OGKB. The GSC-derived aromatics were worth keeping, but OGKB phenotypes are notoriously slow, squat and unproductive. Face Off OG brought vigour, a stronger root system and considerably more punch.
They then applied the same logic again with Moonbow, using Do-Si-Dos to fix Zkittlez. It is the same method one generation on, and it is why so much of our own catalogue traces back to this breeder.
| Archive project | Problem being solved | Solution |
|---|---|---|
| Do-Si-Dos | OGKB grows poorly | Face Off OG vigour and potency |
| Moonbow | Zkittlez yields badly | Do-Si-Dos structure and weight |
| Moonbow #112 IX | Expression drift | Intercross to stabilise |
The Weight Problem
Do-Si-Dos is potent enough that it is easy to overdo, and the onset pattern makes that more likely rather than less.
The initial euphoria is short and pleasant. If you judge by that window you will misjudge the plant, because what follows is considerably heavier and lasts considerably longer.
Start low with anything from this family, and give it a proper 45 minutes before deciding it was underwhelming.

Finding It
Do-Si-Dos is widely grown, so quality varies considerably. Ask for the harvest date and the producer rather than relying on the name, and expect a heavy evening cultivar regardless of who grew it.
