Do-Si-Dos Auto Strain Information

Though slightly indica dominant, Do-Si-Dos Auto is a well-balanced auto strain that descends from Do-Si-Dos, a cross of GSC x Face Off OG, and Cookies Auto, which is an autoflowering Cookies variety created by crossing original GSC with a unique cut of ruderalis. And the results of this unusual cross offer plenty to get excited over.

First of all, Do-Si-Dos Auto boasts an intensified version of the sweet, fruity cookie aroma that made her photoperiod predecessor so famous. At the same time, she also packs up to 20% THC and a strong, soothing effect that eases both physical and mental tension after a single hit. As if that weren't enough, Do-Si-Dos Auto features vigorous growth traits and delivers an excellent harvest indoors and outdoors, in hydro or soil setups. Within weeks and with minimal effort, this US autoflower delivers dense, bright green flowers that look as if they've just come from the top shelf of a dispensary.

Do-Si-Dos Auto Characteristics

Do-Si-Dos Automatic is roughly 60% indica dominant and exhibits a stout, compact structure. She is also quick to deliver a harvest, finishing her entire grow cycle in under two months. Her flowers combine both indica and sativa traits, featuring an elongated form with a tight, dense structure. Her effects, on the other hand, are more indica-leaning, inducing a strong soothing sensation that evokes deep physical and mental relaxation.

Packing an exotic mix of terpenes and up to 20% THC, Do-Si-Dos Auto is potent yet balanced. Her flavours and aromas, on the other hand, combine an explosion of sweet, fruity, and earthy notes—ideal for lovers of Cookies and OG strains.

  • Do-Si-Dos Auto Flavour and Aroma

Do-Si-Dos Auto descends from stellar genetic lines—and has the aromas and flavours to show for it! The plants can become very aromatic by their third or fourth week in bloom, filling the growing space with notes of sweet fruit, citrus, and moist soil. After drying and curing, Do-Si-Dos Auto's aroma becomes much more complex, preserving her upfront sweetness but developing deeper, earthier, and skunkier undertones. Best of all, Do-Si-Dos Auto's flavour is just as delicious as her aroma, perfectly blending sweet, earthy, and skunky notes.

  • Do-Si-Dos Auto Effects

Like the original, Do-Si-Dos Auto packs a heavy effect that'll lull you into a state of carefree bliss within minutes. If you're an experienced user, this is the kind of strain that you can smoke all day (in moderation) without feeling overwhelmed, lethargic, or couch-locked. At the same time, if you're a rookie or have a low tolerance, a few tokes of Do-Si-Dos Auto will elevate your spirits for hours. While her effects are far from energising, Do-Si-Dos Auto is still well-balanced and makes a perfect strain for social situations or creative endeavours.

Growing Do-Si-Dos Auto

Beyond her delicious aromas and potent effects, Do-Si-Dos Auto boasts exceptional growth traits. While she's perfect for rookie growers looking for a no-fuss strain, veteran growers will be hard-pressed to find a downside to adding this vigorous auto to their arsenal. After all, who can argue with a compact, easy-growing auto that churns out up to 400 g/m² or 150 g/plant just 10 weeks after germination? Measuring between 80–140cm, Do-Si-Dos Auto is also a great cultivar for SOG setups, allowing growers to take advantage of her naturally compact stature to create a thick, even canopy.

  • Germinating Do-Si-Dos Auto

Do-Si-Dos Auto is easy to germinate. We suggest storing your seeds in their original packaging until the moment you plan to use them. Then, for the highest germination rates, we recommend using an RQS propagator or the age-old paper towel method—both deliver great results. Once they've sprouted, Do-Si-Dos Auto seedlings should be planted directly in their final containers. From there on out, enjoy as you watch your Do-Si-Dos Auto plants grow vigorously and develop healthy, bright green leaves in weeks.

  • Vegetative Phase

Do-Si-Dos Auto plants veg for roughly 4 weeks before naturally transitioning into their bloom phase. During this time, you'll see your specimens develop a thick central stem as well as a few side branches. If you're growing outdoors, keep Do-Si-Dos Auto in a sunny spot. Indoors, on the other hand, it's best to keep her under an 18-6 light-dark cycle to maximise her brief veg time. In optimal conditions, Do-Si-Dos Auto plants can reach up to 50 cm by their final week in veg. While rookie growers can leave this strain to her own devices, more experienced cultivators might want to implement some low-stress training to open up her canopy.

  • Flowering Phase & Harvest Time

As they transition into bloom, Do-Si-Dos Auto plants may stretch considerably. Indoors, mature plants typically reach 80–120 cm. Outdoors, Do-Si-Dos Auto may grow slightly taller, maxing out at up to 140 cm. By week three of their flowering phase, Do-Si-Dos Auto plants will have formed small but resinous flower clusters that rapidly take on weight in the coming weeks.

On average, Do-Si-Dos Auto needs a full 7–8 weeks of flowering to reach peak maturity. Once mature, she'll have developed a long, thick central cola, large nuggets at the tips of her secondary branches, and smaller buds towards the lower parts of her canopy. Do-Si-Dos Auto flowers typically stay bright green with long, red pistils, though they can also develop light purple hues in cooler environments. Though she is a little leafy, Do-Si-Dos Auto makes for easy trimming—just be sure to keep some alcohol wipes ready to clean your scissors as they're bound to get covered with sticky resin!

Do-Si-Dos Auto Descendants & Relatives

Do-Si-Dos Auto descends from Do-Si-Dos and Cookies Auto. As mentioned, the original Do-Si-Dos was bred around 2016 in Oregon by Archive Seed Bank.
