Dos Si Dos 33 Feminized Cannabis Seeds by Barney's Farm
Dos Si Dos 33 is a feminized cannabis seed from Barney's Farm that crosses Dos Si Dos with Gelato 33, stacking Girl Scout Cookies, Sunset Sherbet, and Face Off OG into one 60% indica / 40% sativa hybrid. The result is a 22–28% THC strain that stays short, resists mould, and delivers yields heavy enough to make experienced growers do a double take. If you want American cookie genetics without the fuss of a temperamental plant, this is the one we'd point you towards.
Pack Sizes
Dos Si Dos 33 comes in two pack sizes: 3 seeds or 5 seeds. If you're running a single tent or just want to pheno-hunt a couple of plants, the 3-pack does the job. Go for 5 if you want a fuller canopy or like having a spare seed or two tucked away — these feminized seeds have a strong germination rate, so you won't be throwing money away.
Flavour and Aroma: Lime Sherbet Meets Fresh-Baked Cookies
From the first whiff, the Cookies lineage announces itself. Girl Scout Cookies brings a minty, slightly herbal edge, while Sunset Sherbet layers in a sweet lime note that's almost creamy. The aroma leans more towards fresh-baked biscuits with a side of smooth lime sherbet — think bakery counter, not fuel station. Despite the Face Off OG parentage, there's very little pine or diesel detectable in this genetic mix. It's all dessert, all the way through.
We've handled a lot of cookie crosses over the years, and Dos Si Dos 33 is one of the few where the sweetness doesn't come across as artificial or one-dimensional. There's genuine depth to the terpene profile. The lime note in particular has a brightness that separates it from the flat "generic sweet" you get from lesser Gelato crosses.
Growing Dos Si Dos 33 Seeds: Simple Enough for First-Timers
Dos Si Dos 33 is one of the most forgiving feminized strains we carry from Barney's Farm. These plants stay short and bushy — proper indica structure — which makes them a natural fit for tents, small rooms, or any setup where vertical space is limited. Mould resistance is genuinely high, so if your grow space runs a touch humid, you're not fighting a losing battle.
Flowering takes 60–65 days indoors. Outdoor growers can expect fully ripe buds by October, comfortably ahead of the autumn rains in most of northern Europe. The buds themselves are a sight: dense nuggets in gold, purple, and green, coated in resin. Yields are massive for a plant this compact.

Complete your grow setup: Pair Dos Si Dos 33 with a Dark Box grow tent and a carbon filter kit if you're growing indoors — the cookie terpenes on this strain are loud, and your neighbours will know about it without proper filtration. A basic pH meter is also worth grabbing if you don't already have one; keeping your feed between 6.0–6.5 in soil will let these genetics express their full colour range.
Why Dos Si Dos 33 Deserves a Spot in Your Grow
We've been stocking Barney's Farm seeds since the early days, and Dos Si Dos 33 is one of those strains that consistently gets repeat orders. The reason is straightforward: it does everything well without demanding much in return. Short, bushy plants that don't stretch into your lights. High mould resistance that forgives the odd ventilation lapse. A 60–65-day flower period that doesn't drag on. And yields that genuinely surprise people the first time round.
The 22–28% THC range puts Dos Si Dos 33 firmly in the heavy-hitter category. If you're after something milder, this isn't it — look at something like Barney's Farm Critical Kush for a more moderate experience. But if you want a strain that maxes out potency while keeping the grow difficulty low, Dos Si Dos 33 hits that sweet spot better than most cookie crosses on the market.
The honest limitation? Because these plants stay so compact, you'll want to do some light defoliation during flower to make sure air and light reach the lower bud sites. Nothing dramatic — just clearing a few fan leaves in week 2–3 of flower. Skip this step and you might find the lower buds are a bit airy compared to the rock-hard colas up top.
The Dos Si Dos 33 Effect: From Energy Jolt to Deep Relaxation
At 22–28% THC, Dos Si Dos 33 delivers a forceful, layered effect that reflects its 60/40 indica-sativa split. The onset is an electric jolt of energy — mentally sharp, uplifting, the kind of initial rush that makes you want to put music on or start a conversation. That gives way to a wave of calm, settled contentment. After the initial phase, the indica side takes over: a comfortable physical stone that settles into deep relaxation and a touch of sedation. It's a two-act experience, and both acts deliver.
According to a study on cannabis-inspired terpene blends, researchers observed prosocial effects from the inhalation of vaporised blends of terpenes found in popular strains including Do-Si-Dos (PMC10311644). The terpene profile of Dos Si Dos 33 — heavy on the sweet, creamy, lime-forward compounds — likely contributes to the smooth character of its overall effect.
Energetic start, sociable middle, couch-locked finish. If you're planning an evening session, time it right — this strain has a clear trajectory, and the sedation at the tail end is real.
How to Grow Dos Si Dos 33
- Germinate your feminized seeds using the paper towel method or directly in a starter plug. Keep temperatures around 22–25°C and maintain humidity at 70–80% during germination. Taproot should appear within 24–72 hours.
- Transplant seedlings into their final containers once the first set of true leaves appears. Dos Si Dos 33 stays compact, so 11–15 litre pots work well for indoor grows. Use a well-draining soil mix with perlite.
- Vegetate for 3–4 weeks under 18/6 light. These plants naturally stay short and bushy, so you won't need aggressive training. Light LST (low-stress training) can open up the canopy and boost light penetration to lower branches.
- Flip to 12/12 lighting to trigger flowering. Expect the 60–65-day flower period to begin from the first signs of pistils, not from the day you switch the lights.
- Defoliate lightly around weeks 2–3 of flower. Remove large fan leaves that block light to lower bud sites. Don't overdo it — these plants aren't heavy stretchers, so a few strategic snips go a long way.
- Monitor humidity during late flower. Despite the high mould resistance, keeping RH below 50% in the final two weeks protects those dense, resinous buds. Good airflow is your best friend here.
- Harvest when trichomes are mostly milky with 10–20% amber for a balanced effect. The gold, purple, and green bud colours will be at their most vivid in the final week, especially if night temperatures drop a few degrees.
- Outdoor growers: plant out after the last frost and expect fully ripened buds by October. The compact structure and mould resistance make Dos Si Dos 33 a solid choice for northern European climates where autumn weather can turn quickly.
Dos Si Dos 33 Compared to Other Barney's Farm Strains
| Strain | THC | Flowering Time | Indica/Sativa | Key Trait |
|---|---|---|---|---|
| Dos Si Dos 33 | 22–28% | 60–65 days | 60/40 | Cookie flavour, massive yields, compact plant |
| Wedding Cake | 24–25% | 60–65 days | 60/40 | Similar lineage, more vanilla-forward flavour |
| Gorilla Zkittlez | 24% | 56–63 days | 60/40 | Fruitier profile, slightly faster finish |
If you're torn between Dos Si Dos 33 and Wedding Cake, the difference comes down to flavour preference. Wedding Cake leans more vanilla and tangy; Dos Si Dos 33 is all about that lime sherbet and cookie dough combination. Potency-wise, they're in the same league. We'd pick Dos Si Dos 33 for the mould resistance alone — it's noticeably more forgiving in humid conditions.
Frequently Asked Questions
Is Dos Si Dos 33 too strong for new growers?
Not at all. Despite the 22–28% THC, the plant itself is one of the easiest in the Barney's Farm catalogue to grow. Short, bushy structure, high mould resistance, and a predictable 60–65-day flowering period. First-timers consistently get good results with this strain.
What does Dos Si Dos 33 smell like during flowering?
Expect a strong cookie and lime sherbet aroma that intensifies from week 4 of flower onwards. The Girl Scout Cookies and Sunset Sherbet parentage dominate the nose. Very little fuel or pine comes through despite the Face Off OG lineage. A carbon filter is strongly recommended for indoor grows — the terpenes on this one are loud.
How tall does Dos Si Dos 33 grow?
These plants stay short and bushy — classic indica structure. Indoor growers rarely see them stretch beyond 80–100cm, making Dos Si Dos 33 a solid fit for tents and low-ceiling spaces. Minimal training needed.
When should I harvest Dos Si Dos 33 outdoors?
Outdoor plants are typically ready by October. This timing works well for northern European growers, as buds ripen before the worst of the autumn weather. Watch trichome colour with a loupe — harvest at mostly milky with some amber for the best balance of effect.
What's the difference between the 3-seed and 5-seed packs?
Same genetics, same quality — just quantity. The 3-pack suits a single tent or a quick pheno-hunt. The 5-pack gives you more plants to work with and a couple of spares. If you're planning a full canopy of Dos Si Dos 33, the 5-pack is better value per seed.
Does Dos Si Dos 33 produce purple buds?
Yes. The buds display a mix of gold, purple, and green colours, especially when night temperatures drop slightly in the final weeks of flowering. The purple colouring is genetic — you don't need to stress the plant to bring it out, though cooler nights do intensify it.
Is Dos Si Dos 33 indica or sativa?
It's a 60% indica, 40% sativa hybrid. The indica dominance shows in the plant structure (short, bushy) and the later stages of the effect (physical relaxation, sedation). The sativa side comes through in the initial energetic onset.
