Dos Si Dos Auto Cannabis Seeds by Barney's Farm

Dos Si Dos Auto is an autoflowering feminised cannabis seed from Barney's Farm that delivers the dessert-sweet terpene profile and heavy indica relaxation of the original Dos Si Dos in a compact, fast-finishing format. Bred from Face Off OG crossed with Girl Scout Cookies, then stabilised with BF Super Auto #1, this 65% indica-dominant auto produces dense, resinous colas in just 70–75 days from germination. If you want photoperiod-level yields without the light schedule fuss, this is where you start.

Dos Si Dos Auto Genetics and Lineage

Dos Si Dos Auto carries a pedigree that reads like a greatest-hits list. The original Dos Si Dos is a cross of Face Off OG — a heavy-hitting OG Kush phenotype — and Girl Scout Cookies, the strain that launched a thousand dessert-themed cultivars. Barney's Farm took that already proven combination and crossed it with their proprietary BF Super Auto #1 to lock in autoflowering behaviour without sacrificing potency or yield.

The result is a 65% indica / 35% sativa genetic profile. You get the structural density and physical relaxation of the indica side, with just enough sativa influence to keep the terpene complexity interesting. The BF Super Auto #1 backbone is what gives this plant its vigour — she grows fast, stays compact, and doesn't need a 12/12 light flip to start flowering. That's a genuine advantage if you're running a perpetual harvest or growing in a space where light control is awkward.

Why Dos Si Dos Auto Outperforms Most Autos

Most autoflowering strains ask you to accept a trade-off: speed and simplicity in exchange for smaller yields and less potent buds. Dos Si Dos Auto doesn't play that game. At 600g/m² indoors, she rivals — and in some setups outperforms — photoperiod strains that take weeks longer to finish. Outdoors, 800g/plant is the kind of number that makes you double-check the seed packet.

We've seen a lot of autos come through over the years. The ones that stick around are the ones that don't make you feel like you're settling. Dos Si Dos Auto is one of those. The cola structure is dense and properly frosted — none of that airy, larfy growth you sometimes get with rushed autoflower genetics. The buds have weight to them. You can feel it when you hold a dried cola between your fingers: sticky, compact, and coated in trichomes that catch the light.

The honest limitation? She's not the most forgiving if you overwater in the first two weeks. Autos don't have the recovery time that photoperiods do, and Dos Si Dos Auto is no exception. Overdo it early and she'll stunt. Keep the soil moist, not soaked, and let the roots chase the water down. Once she hits week three, she's a tank.

Flavour Profile and Terpenes of Dos Si Dos Auto

The name gives you a clue — Dos Si Dos Auto smells like a bakery that's been left unsupervised. Expect a sweet, doughy base layered with earthy undertones and a sharp lime zest that cuts through on the exhale. The Girl Scout Cookies parentage brings that unmistakable cookie sweetness, while Face Off OG contributes a deeper, fuel-tinged funk that grounds the whole profile.

When you crack open a cured jar, the first thing that hits you is a warm, almost caramel-like sweetness — rich and rounded, not cloying. Give it a moment and the earthier notes emerge: damp soil, a hint of pine, and something almost spicy sitting underneath. It's a complex terpene profile that rewards a slow cure. Rush the dry and you'll lose the subtlety. Give her 10–14 days in jars with daily burping and the flavour develops properly.

Interestingly, according to a study on cannabis-inspired terpene blends, researchers observed prosocial effects from the inhalation of vaporised blends of terpenes found in popular cannabis strains including Do-Si-Dos (PMC10311644). The terpene combination in this lineage is clearly doing something worth paying attention to.

Growing Dos Si Dos Auto Indoors

Dos Si Dos Auto reaches about 100cm indoors — manageable in most tents from 60x60 upwards, though we'd pick an 80x80 or larger if you want to fit multiple plants without crowding. She responds well to LST (low-stress training), which keeps the canopy flat and exposes more bud sites to your light. Main-lining is another option if you want to push for maximum cola uniformity, though it's more hands-on.

1. Germinate seeds using the paper towel method or directly in a small pot of moist, airy soil. Keep temperatures between 22–26°C.
2. Transplant into the final container (11–15L fabric pot) as soon as the taproot emerges. Autos don't like being repotted mid-grow — start in the final pot if you can.
3. Run lights on an 18/6 or 20/4 schedule from seed to harvest. No light cycle change needed.
4. Begin LST once the plant has 4–5 nodes. Gently bend the main stem away from the centre and secure with soft ties. Open up the canopy to let light reach lower branches.
5. Feed lightly in the first two weeks — autos are sensitive to nutrient burn early on. Increase feeding gradually as she enters pre-flower around week 3–4.
6. Watch for the stretch during early flowering. She'll gain height quickly for about 10 days, then focus energy on bud production.
7. Harvest at 70–75 days from germination. Check trichomes with a jeweller's loupe — mostly milky with 10–20% amber is the sweet spot for a relaxing indica effect.

At 600g/m², you're looking at seriously impressive returns for an auto. That number assumes decent lighting (400W+ LED or equivalent), proper airflow, and a grower who doesn't panic-feed. Keep it simple, keep it consistent, and she'll deliver.

Growing Dos Si Dos Auto Outdoors

Outdoors, Dos Si Dos Auto stretches to around 140cm and can produce up to 800g per plant — a figure that puts many photoperiod strains to shame. She's built for garden beds, large containers (30L+), and balconies that get at least 8 hours of direct sun.

The 70–75 day lifecycle means you can start seeds in late spring and harvest well before autumn rains become a problem. In northern European climates, that's a genuine advantage. No waiting until October and praying the mould doesn't get there first.

One tip that's worth the effort: surround your plants with companion species like dill and yarrow. Dill attracts ladybirds and hoverflies — both of which eat aphids — while yarrow draws in parasitic wasps that target caterpillars. It's low-effort pest management that actually works, and it looks better than a ring of yellow sticky traps.

Dos Si Dos Auto Compared to the Photoperiod Original

If you're deciding between Dos Si Dos Auto and the photoperiod version, here's the honest breakdown:

The auto version is the better pick if you want speed, simplicity, and stealth. The photoperiod gives you more control over plant size and potentially larger yields if you veg longer. Both carry the same knockout terpene profile. We'd point first-time growers toward the auto without hesitation — and experienced growers running perpetual harvests will appreciate the fixed timeline.

What to Expect from Dos Si Dos Auto Buds

The colas on Dos Si Dos Auto are dense, chunky, and absolutely caked in trichomes. The bud structure leans heavily toward the indica side — tight, rounded nugs with deep green calyxes threaded through with orange pistils. Under good lighting, the trichome coverage gives the buds an almost white-frosted appearance. They're the kind of colas that look as good as they smell.

The indica-dominant genetics produce a physically relaxing effect that settles into the body. It's traditionally associated with evening use — the kind of strain you reach for when the day's done and you want to properly switch off. The 65% indica profile means there's still some mental clarity in the mix, at least early on, before the body relaxation takes over.

According to strain data from multiple sources, Dos Si Dos phenotypes can reach THC levels of up to 30% in optimal conditions. The auto version carries the same genetic potential, though actual potency depends on your growing environment, nutrition, and curing process. Expect strong results with proper care.
