Growing Fast Version Seeds
A Fast Version is not an autoflower. Although Do-Si-Dos Fast Version carries fast-flowering genetics in its background, it is still a photoperiod plant, so it flowers on a light change rather than purely on age. You grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 cycle to trigger flowering, exactly as you would with any fast-flowering strain.
What you gain is speed: once you flip, this Fast Version finishes its bloom faster than a standard photoperiod Do-Si-Dos, in around 8–10 weeks. That shorter flowering window makes it a great fit for growers who want the potent, high-THC Do-Si-Dos profile without the longer wait, and it is a real advantage for outdoor growers racing an early autumn.
Climate and Where to Grow It
Do-Si-Dos Fast Version does best in a temperate climate with plenty of light and good airflow. It is a sturdy, adaptable plant that performs both outdoors and in a controlled indoor tent, reaching a medium 1.5 m, so it fits most spaces without demanding a tall room as it moves into flower.
Outdoors it rewards a good spot with 250–300 g per plant, while indoors it produces a strong 400–500 g/m². Those are solid numbers for a fast, manageable plant, but they depend on light, pot size and canopy health, so give it room and feed it steadily to reach the top of the range.
Indoors, aim for daytime temperatures around 70–82°F (21–28°C) and keep steady airflow moving through the canopy. Its dense, resin-heavy indica buds hold moisture, so keep humidity in check as flowering fills in, and give the branches a little support once the sticky, trichome-packed colas start to swell.
Feeding Schedule (EC Guide)
This is a resinous, high-THC indica that sets dense, sticky buds, so feed it steadily but without overdoing it. Start low, build up as the plant asks for more, and taper right off for the final flush so the earthy, sweet flavor comes through clean and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the sticky buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs a quick 8–10 weeks, faster than a standard Do-Si-Dos. As a 70% indica it stays sturdy and bushy, filling in dense, chunky, resin-coated buds that gain weight and frost over heavily through the second half of flowering, which is where its high 26–30% THC comes from.
Give the colas light support as they fatten, and keep the canopy open so light reaches the lower flowers. Harvest when most trichomes have turned cloudy with a few amber heads for the fullest expression, and run a short plain-water flush in the last week or two before you cut the plant down.
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 stops the dense, sticky buds staying damp in the middle while the outside dries out, which protects both the earthy-sweet aroma and the heavy resin.
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 brings the earthy, sweet notes forward and smooths the smoke, which is exactly what this potent Kush-lineage Fast Version deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Do-Si-Dos Fast Version is a famously frosty, resin-rich plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of potent, earthy-sweet concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Do-Si-Dos Fast Version keeps the classic Do-Si-Dos profile: a rich, earthy base with a soft, sweet, cookie-like finish. It is a smooth, moreish taste rather than a sharp or fruity one, carried straight from its Do-Si-Dos lineage into the cured flower on a faster-finishing plant, and it is a big part of the strain’s appeal.
Its terpene profile is compact but expressive, led by cedrene for the woody, earthy base and bisabolol for a soft, sweet floral note, with linalool adding a gentle floral touch, terpinolene a fresh lift and pinene a clean, sharp top note. Together they frame the earthy-sweet, cookie-like character that comes through from the Do-Si-Dos and Girl Scout Cookies side of its heritage.
Effects and Best Use
With its indica-dominant genetics, Do-Si-Dos Fast Version is reported as happy, relaxed and talkative, a comfortable, full-bodied wind-down lifted by a cheerful, sociable mood. It is best kept for the evening, easing into deep physical relaxation while staying pleasant and chatty rather than purely heavy, so it works well for unwinding with company.
At a high 26–30% THC it is seriously potent, among the strongest in the catalogue, so newer users should go slow while experienced users will appreciate the depth and heavy resin it brings. That character, the earthy-sweet flavor, the elite Do-Si-Dos heritage and the fast-finishing, frosty plant are exactly why growers reach for it.
Common Problems and Pro Tips
The main thing to watch with Do-Si-Dos Fast Version is humidity around its dense, resin-heavy indica buds. Those sticky, trichome-packed colas trap moisture, so bud rot is the most common problem in the final weeks of flower. Keep humidity moderate through the second half of bloom, run steady airflow, and a light defoliation of the inner canopy helps air reach the thickest buds.
Its very high THC is worth respecting too. At 26–30% this is one of the most potent strains you can grow, so cure it carefully to get the smoothest possible smoke from all that resin, and if you are newer to strong cannabis, plan to go slow with the finished product rather than expecting a mild, casual high.
As a pro tip, lean into what a Fast Version does best: its quick 8–10 week bloom lets you fit an extra outdoor run or beat an early, wet autumn, so time your planting to harvest before the rains. Keep the feed moderate to protect the earthy-sweet terpenes, give it a clean plain-water flush at the end, and follow the trichomes rather than the calendar for the best finish.
FAQ
Is Do-Si-Dos Fast Version an autoflower?
No. Despite the fast-flowering genetics in its background, Do-Si-Dos Fast Version is a photoperiod plant, so it flowers on a light change rather than purely on age. You grow it under long days, then flip to a 12/12 cycle to start bloom. What it gives you is a faster finish than a standard Do-Si-Dos, not autoflowering behaviour.
Is Do-Si-Dos Fast Version indica or sativa?
It is strongly indica-dominant, at roughly 70% indica and 30% sativa, from its Do-Si-Dos heritage. That shows in a deep, comfortable body relaxation best suited to the evening, while the sativa share keeps the effect happy and talkative, so it stays sociable and pleasant rather than purely heavy and flattening.
What does Do-Si-Dos Fast Version taste like?
It keeps the classic Do-Si-Dos profile: a rich, earthy base with a soft, sweet, cookie-like finish. Cedrene drives the woody, earthy depth, bisabolol and linalool add a soft floral sweetness, and the cookie-like character comes through from the Girl Scout Cookies side of its Do-Si-Dos lineage.
What is Do-Si-Dos Fast Version’s THC level?
It carries a very high THC of 26–30%, among the strongest strains in the catalogue. That potency drives a happy, relaxed, talkative effect that is genuinely powerful, so newer users should start with a small amount and build up slowly, while experienced users will enjoy the depth and heavy resin it delivers.
How long does Do-Si-Dos Fast Version take to flower?
A quick 8–10 weeks once you switch to a 12/12 light cycle, faster than a standard photoperiod Do-Si-Dos. It is a Fast Version, so it blooms on the light change rather than on age but finishes sooner, which makes it a strong choice for outdoor growers racing an early autumn or anyone wanting a shorter cycle.
How much does Do-Si-Dos Fast Version yield?
It is a solid producer for a fast, compact plant, giving around 400–500 g/m² indoors and 250–300 g per plant outdoors. Those numbers depend on light, pot size and canopy health, so give it room, support the branches, and feed it steadily through its quick bloom to reach the top of the range.
