How to Grow Do-Si-Dos F1
Do-Si-Dos F1 is a very potent, heavily indica feminized F1 hybrid that crosses Face Off OG with Girl Scout Cookies. The result is a 75% indica plant with a high 26-30% THC, an earthy, minty, kush and sweet flavor, and an energetic, powerful and relaxed effect. As a first-generation hybrid it grows with real vigour and uniformity, and it is both productive and beginner-friendly.
This is a feminized F1, 75% indica photoperiod strain of moderate height, around 1.5 m, that flowers in 8 to 9 weeks once you switch it to bloom. Every seed grows into a flowering female, so there is no need to identify the sex or remove males, which keeps the grow simple and the whole crop productive. Its Face Off OG and Girl Scout Cookies roots give it a sturdy, bushy structure and a very resinous, high-THC harvest.

What an F1 Hybrid Means for Growers
Do-Si-Dos F1 is a first-generation hybrid, which is what the “F1” stands for: the first cross between two distinct parent lines, here Face Off OG and Girl Scout Cookies. First-generation crosses benefit from what breeders call hybrid vigour, so an F1 tends to grow faster and stronger and to be more stable and uniform than later generations. In practice that means your plants come up looking and behaving alike, which makes the grow easier to plan and manage.
For a grower, that uniformity is a real advantage. A tent full of plants that stretch, flower and finish on much the same schedule is simpler to feed, train and harvest than a mix of different phenotypes. Combined with the feminized seeds, where every plant is female, an F1 like this takes a lot of the guesswork out of a grow while still delivering the potency and flavor of its parent lines.
Growing a Feminized Photoperiod Strain
Do-Si-Dos F1 is a photoperiod strain, so it flowers in response to the light cycle rather than on age. You grow it under a long day of around 18 hours of light while it builds size and structure, then switch to a 12/12 light schedule to trigger flowering, which runs 8 to 9 weeks from the flip to harvest. Because the seeds are feminized, every plant comes up female and goes on to flower, so you never have to check the sex or cull males.
That control over the light cycle is an advantage. You decide how long to veg the plants and therefore how big they get before you flip them, which lets you match them to your space. As a 75% indica it grows bushy and compact rather than tall, so give it an open canopy and a little low-stress training early on to spread the light evenly and get the most from its very resinous structure.
Climate and Where to Grow It
Do-Si-Dos F1 does best in a warm, tropical or Mediterranean-style climate with plenty of sun, steady warmth and good airflow. Its vigorous F1 genetics make it adaptable and forgiving, and outdoors it suits a long, warm season that lets its dense, resinous buds ripen fully and finish comfortably by around September.
It performs well indoors and out, and outdoors the potential is huge. Indoors it returns a strong 475-525 g/m² in a well-managed tent, while outdoors a healthy plant with room for the roots and a full season of sun can reach a very high 800-1200 g, which is why it also sits among our high-yielding seeds. As a bushy indica of about 1.5 m it stays manageable in height, so the main job is keeping the canopy open.
Keep humidity under control through flowering to protect the dense, resinous colas: around 55-60% in early bloom, nearer 40-45% as the buds fill out, and lower toward harvest. A chunky, high-THC indica can hold moisture inside the flowers, so steady airflow and sensible humidity are what keep the finish clean. Aim for daytime temperatures around 70-82°F (21-28°C).
Feeding Schedule (EC Guide)
Do-Si-Dos F1 is a hungry, productive plant, but it still pays to build nutrients up gradually and let the plant set the pace. Feed to its appetite through veg and bloom, then taper off for the final flush so the earthy, minty and sweet flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed while roots establish |
| Vegetative growth | 0.8-1.2 | Raise nitrogen as the plant builds size |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you switch Do-Si-Dos F1 to a 12/12 light schedule it flowers in 8 to 9 weeks, which is quick for such a potent, resinous indica. As a mostly indica plant it stacks dense, chunky, frosty buds on a bushy frame rather than stretching tall, so you get a lot of high-THC flower in a modest footprint. Grown outdoors in a warm climate it is typically ready to harvest around September.
Yields are strong, and outdoors they can be exceptional: around 475-525 g/m² indoors and a very high 800-1200 g per plant outdoors with a big pot and a full season of sun. Give it a little training so the lower buds get light, feed it well through bloom, and harvest when most of the trichomes have turned cloudy for the fullest flavor and the strongest effect from its very high THC.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry is especially important with a dense, high-THC indica like Do-Si-Dos F1, because its chunky buds can stay damp in the middle while the outside dries, and a gentle dry protects both the aroma and the trichomes.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings out the earthy, minty, kush and sweet notes and smooths the smoke, which matters on a potent strain like this where a clean, full flavor makes the strength more enjoyable.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Do-Si-Dos F1 is a very resinous, trichome-heavy plant, so its trim works well for dry sift, bubble hash or rosin. Given its very high THC, that trim makes for a strong, flavourful kush-and-mint concentrate run from material most growers would otherwise throw away.
Flavor and Terpenes
Do-Si-Dos F1 has a rich, old-school profile: a deep earthy, kush base from its Face Off OG side, a cool minty edge, and a sweet, cookie-like finish carried over from Girl Scout Cookies. It is a full, savoury-sweet flavor rather than a fruity one, and a good cure really brings that earthy-mint-and-sweet character forward in the jar and on the inhale.
Its terpene profile shapes that character. Myrcene lays down the ripe, earthy-herbal base that drives the heavy indica body, while linalool adds a soft, slightly floral sweetness that rounds out the cookie-like side. Alpha-pinene brings a fresh, piney lift that reads as the cool, minty note on top. Together they frame the earthy, kush, minty and sweet character Do-Si-Dos F1 is known for.
Effects and Best Use
With its very high 26-30% THC and heavily 75% indica make-up, Do-Si-Dos F1 delivers a strong, powerful experience. It is reported as energetic, powerful and relaxed: an initial lively, uplifting push that settles into a deep physical relaxation, a potent effect that reflects its high THC. Because the THC runs very high, it is well worth starting with a moderate amount, especially if you have a lower tolerance.
That powerful, relaxed profile makes it best suited to the evening and to experienced users, though its energetic start gives it some versatility earlier in the day. The combination of a productive, beginner-friendly F1 grow, a big yield and a rich earthy-mint-and-sweet flavor, all with a very high-THC kick, is exactly why it stands out.
Common Problems and Pro Tips
The most common issue with a dense indica like Do-Si-Dos F1 is moisture getting trapped in the chunky, resin-heavy buds late in flower. Keep the air moving around and through the canopy, hold humidity down as the flowers fill out, and don’t let the plant sit in still, damp air. Defoliating a few of the largest fan leaves in mid-bloom helps light and air reach the lower buds.
Because it grows bushy and compact rather than tall, train it early. A little low-stress training or a light topping in veg opens the canopy and turns one dominant cola into several even ones, which suits its productive structure and lifts the yield. Its uniform F1 growth makes this easy to apply across a whole tent of plants at once. Outdoors, give it a large pot and a full season of sun to reach that headline yield.
As a pro tip, respect the potency: this is a very high-THC strain, so cure it well for three to four weeks to make the strength smooth and enjoyable, and start with a moderate amount when you first try it. Protect the earthy-mint flavor with a clean plain-water flush, and lean on the plant’s vigorous, uniform F1 nature by keeping the feed steady and the canopy open.
FAQ
What does F1 mean for Do-Si-Dos F1?
F1 means first-generation hybrid, the first cross between two distinct parent lines, here Face Off OG and Girl Scout Cookies. First-generation crosses show hybrid vigour, so they tend to grow stronger and more uniformly than later generations. For a grower, that means a tent of plants that look and behave alike, which makes feeding, training and harvesting simpler.
How much THC does Do-Si-Dos F1 have?
Do-Si-Dos F1 is a very high-THC strain, testing at around 26-30%. Because it runs so high, it is well worth starting with a moderate amount if your tolerance is lower. Combined with its heavily 75% indica genetics, the result is a powerful experience that starts energetic and settles into a deep, relaxed body effect.
How long does Do-Si-Dos F1 take to flower?
Do-Si-Dos F1 flowers in about 8 to 9 weeks once you switch it to a 12/12 light schedule, which is quick for a resinous indica. As a photoperiod strain you also control how long it vegetates beforehand, which sets its final size. Grown outdoors in a warm, tropical climate it is usually ready to harvest around September.
What does Do-Si-Dos F1 taste like?
It has a deep earthy, kush base from Face Off OG, a cool minty edge, and a sweet, cookie-like finish from Girl Scout Cookies. Myrcene drives the earthy base, linalool a soft floral sweetness, and alpha-pinene the fresh, minty lift. A proper cure brings the earthy-mint-and-sweet character forward and smooths out the smoke.
How much does Do-Si-Dos F1 yield?
It is a strong producer: around 475-525 g/m² indoors and a very high 800-1200 g per plant outdoors with a big pot and a full season of sun, which places it among our high-yielding seeds. Results depend on light, pot size and canopy health, so feed it well through bloom and train it lightly for an even, productive canopy.
Is Do-Si-Dos F1 good for beginners?
Yes. It is a feminized F1, so every seed is female and the plants grow with vigour and uniformity, which makes the cultivation forgiving and easy to plan. The main thing to watch is its very high THC, so go easy on the smoke at first, along with humidity around the dense buds, which steady airflow keeps in check.
