To grow the Do Si Dos cannabis strain from seed, germinate a quality seed, plant it straight into its final container, give it plenty of light and gentle low stress training, feed lightly and harvest when the trichomes look mostly cloudy. Our Do Si Dos Auto flowers on its own schedule, so you do not need to change your light cycle. This guide is for adults 21 and older where home growing is legal, and walks through every stage from seed to jar.

Meet Do Si Dos

Do Si Dos, sometimes written Dosidos, is a modern West Coast hybrid that became popular in the mid 2010s. It is widely described as a cross of Girl Scout Cookies and Face Off OG, which puts it in the Cookies family alongside many of today’s dessert style strains. Growers know it for heavy resin and compact, tight flowers.

The Do Si Dos Auto sold by Kind Seed Co brings that profile into an autoflowering package. Autoflowers carry ruderalis genetics, so they flower based on age rather than day length. They tend to stay more compact than photoperiod versions and finish faster.

Typical ranges for Do Si Dos

Autoflower versions of strains like this are commonly listed at roughly 9 to 11 weeks from seed to harvest, and many finish somewhere around 2 to 4 feet tall indoors. These are typical ranges reported for this kind of plant, not promises. Light, pot size, training and climate all move the numbers, and the Do Si Dos Auto product page is the place to check current specs before you plan your space.

What to expect from Do Si Dos in the garden

Do Si Dos grows as an indica leaning plant with broad leaves, short spaces between branches and a sturdy frame. The autoflower version keeps that compact shape and fits small tents well. Buds tend to be dense and frosty, and some plants show purple or dark green coloring late in flower, especially with slightly cooler nights.

In short, look for dense, frosty buds that can pick up purple hues late in flower and an aroma that leans sweet, earthy and floral with a hint of lime. Every plant is a little different, and your setup, light and care will shape the final result as much as genetics.

Before you start

• Check your local laws. Grow only where home cultivation is legal under your state’s law and stay within your plant limit. You must be 21 or older. Federal treatment of cannabis seeds is also changing, so read our December 11 2026 seed rule explainer.
• Pick your space. A 2×2 or 2×4 tent suits one or two autoflowers.
• Gather supplies. A quality full spectrum LED, a 3 to 5 gallon fabric pot, a light, airy soil or coco mix, a small fan, a pH meter and a timer.

Grow basics to read first

If this is your first grow, these guides cover the fundamentals that every strain needs:

• Autoflower seeds 101
• VPD chart for cannabis
• Cannabis trichomes 101
• Cannabis drying temperature and humidity

Step 1: Germinate the seed

1. Soak the seed in clean, room temperature water for 12 to 24 hours, or until it sinks.
2. Move it to a damp paper towel inside a covered plate in a warm, dark spot.
3. Check daily. When a small white taproot appears, it is ready to plant.

Handle the taproot gently and plant it root down about a quarter to half an inch deep.

Step 2: Plant directly into the final pot

Autoflowers do not love transplant shock, and they have a short life. Planting straight into the final pot saves time and stress. Moisten the soil before planting so it is damp, not soggy.

Step 3: The seedling stage

• Keep the light at a gentle intensity and a comfortable distance.
• Water lightly in a small circle around the stem.
• Keep humidity moderately high and temperatures comfortable.
• Many autoflower growers run 18 hours of light and 6 of dark, or 20 and 4, for the whole grow.

Step 4: Vegetative growth

Do Si Dos Auto has a short veg window, so gentle training goes a long way.

• Low stress training (LST). Gently bend the main stem and tie it down so the side branches can rise and form an even canopy.
• Skip heavy topping on autos. Some growers top autoflowers early, but beginners usually get better results with LST alone.
• Feed lightly. Autoflowers are often light feeders. Start at a fraction of the label dose and watch the leaves.
• Water wisely. Let the top inch of soil dry before watering again.

Step 5: Flowering

Your Do Si Dos Auto will start flowering on its own. You will see white pistils forming at the branch tips.

• Shift nutrients. Move toward a bloom formula with more phosphorus and potassium.
• Support branches. Use soft ties or a trellis net if colas get heavy.
• Lower humidity. Keep air moving and humidity lower to protect buds from mold.
• Keep the canopy even. Continue gentle LST through early flower.

Protecting dense buds from rot

Do Si Dos tends to stack tight, heavy flowers, and dense buds hold moisture. Keep humidity lower in late flower, keep a fan moving air through and under the canopy, and thin out crowded inner growth before the flip or early in flower. Check the inside of the biggest colas in the last weeks for gray or brown patches. Our guide to bud rot in cannabis shows what to look for and what to do.

Do Si Dos specific tips

• Start LST early, around the third or fourth node, because the short internodes can make the canopy crowded.
• Remove a few large fan leaves in early flower to open the plant to light and air.
• Keep a close eye on humidity in the last three weeks, when the buds are densest.

Step 6: Know when to harvest

The best way to time your harvest is to look at the trichomes, the tiny resin glands on the buds, with a jeweler’s loupe or clip on macro lens.

• Clear trichomes: not ready yet.
• Mostly cloudy: many growers harvest here.
• Some amber: some growers wait for a portion of amber.

Pistils also darken and curl as harvest nears. Use the product page’s flowering time as a guide, but let the trichomes have the final say.

Step 7: Dry and cure

1. Cut branches and hang them in a dark space with gentle airflow and moderate humidity.
2. When small stems snap rather than bend, trim and place buds in airtight glass jars.
3. Open the jars briefly each day for the first couple of weeks, then less often.

A slow dry and patient cure bring out the full Do Si Dos aroma.

Growing Do Si Dos as a photoperiod

If you grow a photoperiod Do Si Dos instead, you control when it flowers by switching your light to 12 hours on and 12 hours off. Expect a taller, longer project with more room for topping and training. The autoflower version is the simpler starting point.

Growing Do Si Dos Auto outdoors

Where outdoor home growing is legal, Do Si Dos Auto can do well in a sunny, private spot. Because it is an autoflower, you can plant after your last frost and harvest before fall weather turns. Use a large pot or well prepared bed, protect plants from heavy rain and keep them out of public view as your state requires.

A simple Do Si Dos shopping list

• One or two Do Si Dos seeds, within your legal plant limit
• A 3 to 5 gallon fabric pot per plant
• Light, airy soil or a coco and perlite mix
• A full spectrum LED light sized for your tent
• An oscillating clip fan and a small exhaust fan with a carbon filter
• A pH meter or test kit
• Soft plant ties for LST
• A jeweler’s loupe for checking trichomes
• Airtight glass jars for curing

Common Do Si Dos growing mistakes

• Overwatering seedlings. Small roots in a big pot drown easily.
• Overfeeding. Burnt leaf tips are a sign to back off.
• Ignoring height. Plan your tent height and use LST early.
• High humidity in late flower. Buds need good airflow.
• Harvesting by calendar alone. Check trichomes.
