Blueberry Strain Autoflower SeedsDJ Short's berry indica on a small, quick ruderalis frame
5.00 out of 5 · 2 reviewsThe Blueberry strain as an autoflower keeps the sweet berry nose of DJ Short's classic indica but flowers by itself, with no light-schedule change. Dutch Passion's Auto Blueberry, one of the longest-running versions, is a Blueberry female crossed with an indica autoflower and is usually ready 8 to 10 weeks from seed, staying around 50–75 cm tall. That makes it a natural fit for small tents, windowsills and balconies.

What is the Blueberry strain as an autoflower?
Blueberry Auto is the autoflowering form of Blueberry, the berry-scented indica DJ Short developed in the United States, made by crossing a Blueberry female with an indica-dominant ruderalis line. Dutch Passion, which worked with DJ Short, lists its Auto Blueberry at 8–10 weeks from seed, 50–75 cm tall and 350–500 g/m² indoors. Breeders rate its THC only as high; the 16–24% range often quoted is for photoperiod Blueberry.
Zativo's Blueberry Autoflowering on SeedFinder lists 70% indica, 20% sativa and 10% ruderalis; shown here as the indica and sativa shares only.
Dutch Passion counts its Auto Blueberry among the fastest autos in its range, averaging 8 to 9 weeks.
Blueberry strain specs
The grow rows describe Dutch Passion's Auto Blueberry, the best-documented Blueberry autoflower, cross-checked with Zativo's version on SeedFinder and other seed bank listings. Strain rows such as THC and terpenes come from photoperiod Blueberry data on Leafly and AllBud, because no breeder publishes a lab profile for the auto.

Where does the Blueberry strain come from?
Blueberry Auto starts with Blueberry, the Thai-and-Afghan indica DJ Short bred in the United States from the late 1970s, which seed companies later crossed with ruderalis for automatic flowering. Dutch Passion says its Auto Blueberry comes from the Blueberry genetics in its gene bank, dating to its work with DJ Short in bringing Blueberry to Europe.
To build the auto, Dutch Passion crossed a selected Blueberry female with an indica-dominant autoflower, backcrossed the offspring to the F4 generation and then self-pollinated them to make F5 seeds. The ruderalis donor is not named. Other seed companies, including Zativo, sell their own Blueberry autoflowers, so timing and size can differ between seed sources.
How is Blueberry Auto different from photoperiod Blueberry?
Blueberry Auto flowers on its own a few weeks after sprouting, while feminized and regular Blueberry only bloom once nights reach 12 hours. The auto finishes in about 8 to 10 weeks from seed and stays around 50–75 cm, so it gives up some yield per plant in exchange for speed, small size and more than one outdoor harvest per season.
Color still shows up. Dutch Passion notes that cool nights near the end of flowering can turn Auto Blueberry plants dark purple, much like the photoperiod strain.
How does Blueberry Auto smell, and what effects do people report?
Aroma and flavor
Blueberry Auto is known for a strong, fruity blueberry scent that sometimes leans toward sweet grape, with earthy, hash-like notes from its Afghani background, according to Dutch Passion.

- Grape
- Sweet
- Earthy
- Hash
Terpenes

Reported effects
Dutch Passion and growers describe Auto Blueberry's effect as a soothing, heavy body high that suits the evening, in line with the relaxed, contented feel reported for photoperiod Blueberry on Leafly and AllBud.
- Soothing
- Body-heavy
- Content
- Drowsy
Blueberry Auto's reported downsides are dry mouth, dry eyes and grogginess if used too early in the day.
These Blueberry Auto notes combine Dutch Passion's description with Leafly and AllBud user reports for the Blueberry family. Reactions differ between people, and nothing here is medical advice.
How do you grow Blueberry seeds?
Growing Blueberry Auto seeds is simple: plant each seed in the container it will finish in, keep one long daily light schedule from start to end, and let the plant start blooming by itself. Expect most plants to be harvest-ready about 8 to 10 weeks after they sprout.
- GerminateDays 1–7
Sow the Blueberry Auto seed where it will finish, in a 10–15 liter (3–4 gallon) pot of airy mix.
- Early growthWeeks 2–3
Blueberry Auto grows fast and short. Tie the main stem down gently if you want a flatter canopy.
- FlowerWeeks 3–9
Flowers appear without any light change. Keep feeding moderate and humidity in check as the berry smell builds.
- HarvestAbout weeks 8–10
Harvest Blueberry Auto when the trichomes turn milky with a share of amber.
Grow tips for Blueberry
- Keep it in one pot. With only 8 to 10 weeks to work with, Blueberry Auto loses ground after a transplant, so start in the final container.
- Long days, no 12/12. Run 18/6 or 20/4 from start to finish; Blueberry Auto times its own bloom and does not need a dark period.
- Train lightly and early. Low-stress training in weeks 2 to 3 opens up the small plant; skip hard topping, which can stall an auto.
- Cool nights for color. Dropping night temperatures a few degrees in the final weeks can bring out the purple tones Blueberry is known for.
- Set yield expectations. Dutch Passion reports home growers averaging about 50 g per plant, with strong LED and hydro setups passing 200 g.
- Grow several outdoors. Outdoor Blueberry Auto gives about 25–75 g per plant, so a few staggered plantings from spring to midsummer add up.

Blueberry strain FAQ
How long does Blueberry Auto take from seed to harvest?
Blueberry Auto is usually ready about 8 to 10 weeks after germination. Dutch Passion gives 8–10 weeks for its Auto Blueberry and says most plants average 8 to 9 weeks, while some other seed banks list their Blueberry autos at up to 11–12 weeks.
How tall does Blueberry Auto grow?
Most Blueberry Auto plants stay around 50–75 cm (20–30 inches), according to Dutch Passion. In very strong conditions, such as hydro under powerful lighting, a plant can pass 100 cm, but that is unusual.
How much does Blueberry Auto yield?
Dutch Passion lists 350–500 g/m² indoors and about 25–75 g per plant outdoors for Auto Blueberry. It says typical home growers harvest around 50 g per plant, and strong LED or hydro setups can exceed 200 g.
Does Blueberry Auto need a 12/12 light cycle?
No. Blueberry Auto carries ruderalis genetics, so it flowers by age under the same 18/6 or 20/4 schedule it grows under. Only photoperiod Blueberry needs 12 hours of darkness to bloom.
How strong is Blueberry Auto?
Dutch Passion rates Auto Blueberry's THC as high but gives no percentage. Photoperiod Blueberry tests around 16–24% THC on Leafly and AllBud, and autoflowering versions often test somewhat lower, so use that range as a ceiling.
Who bred Blueberry Auto?
Blueberry itself was bred by DJ Short. Dutch Passion, which worked with DJ Short to bring Blueberry to Europe, made its Auto Blueberry by crossing a Blueberry female with an indica-dominant autoflower and stabilizing the line to F5. Other companies, such as Zativo, sell their own versions.
Is Blueberry Auto indica or sativa?
Blueberry Auto is indica-dominant. Zativo's version on SeedFinder is listed as 70% indica, 20% sativa and 10% ruderalis, and Dutch Passion describes its Auto Blueberry as an indica-dominant autoflower with a body-heavy effect.
Does Blueberry Auto turn purple?
It can. Dutch Passion notes that low night temperatures near the end of flowering can turn Auto Blueberry plants dark purple. Warm grows usually stay greener, with only hints of color.

Kelsey Bradshaw –
Blueberry Autoflower has me forgetting I’m sad in the first place. Look no further if you’re searching for medical cannabis for depression and body pain. With high THC levels and this is an excellent daytime smoke. I grew it indoors due to pest issues, and I didn’t have too many problems; all I had to do was keep it nice and wet, and it bloomed in just a few weeks.
Juan Ginn –
Enthusiasts like me pick blueberry auto since I favor fruity, berry, and sweet flavors. The quality was too good; the buds are very thick and resinous. I also look up the beneficial effects that can treat my back pain and muscle pain. The drowsy and calming effects make me reposed. Such a flawless strain!
