Blueberry Auto packs the flavor of a legend into one of the quickest autoflower cycles around. Dutch Passion lists it at just 8-10 weeks from seed to harvest, which means a finished crop in roughly two months, with no switch to 12/12 and no dependence on outdoor day length.
The breeding started with a carefully chosen female from Dutch Passion’s own Blueberry gene bank, the collection that dates back to the company’s work with DJ Short, the original Blueberry breeder. She was crossed with an Indica-dominant autoflower, backcrossed selectively up to the F4 generation to lock in the autoflowering trait, and the F4 was then self-pollinated to create the stable F5 seeds in the pack.
The result is a compact, Indica-leaning plant that usually finishes at 50-75 cm (19.7-29.5 in), with one fat central cola, a few small side buds and a coating of resin that makes the berry aroma impossible to miss. Dutch Passion rates the THC level as high.
Flavor, Effects, and Fast Blue Family Harvests
Most plants carry the classic Blueberry scent: sweet, ripe berries that sometimes drift toward juicy grapes. Underneath, the Afghani heritage can add an earthy, hashy note that rounds out the smoke. Anyone who has tasted genuine Blueberry will recognize it right away.
This is an Indica-style experience. The high settles mostly in the body, bringing deep physical relaxation and a heavy, comfortable calm that suits evenings far better than busy afternoons. The session lasts a few hours and rivals many photoperiod strains.
Late in flowering, the buds can take on dark purple tones, especially when night temperatures drop toward the end of the cycle.
Growing Blueberry Auto Seeds
Blueberry Auto is a forgiving plant that suits first-time growers as well as veterans. Run her under 18/6 or 20/4 from germination all the way to harvest. Soil and coco both work well, and coco gives newer growers faster root development and bigger plants. Hydro systems such as DWC or RDWC push growth hardest, although Dutch Passion recommends them mainly for experienced hands.
Because most of her energy goes into the main cola, she is ideal for a Sea of Green. A controlled indoor room typically produces 350-500 g/m² (1.15-1.64 oz/ft²), depending on plant count, method and skill. Most home growers land around 50 g (1.8 oz) per plant, while a strong LED paired with hydro can lift that above 200 g (7.1 oz) per plant. In exceptional conditions she may even pass 100 cm (39 in).
Outdoors, pick the sunniest spot available. Good light keeps the buds firm; in shade they stay airier and the yield drops. A typical outdoor plant gives 25-75 g (0.9-2.6 oz). Since autos ignore day length, you can sow several rounds between spring and late summer for multiple harvests in one season.

FAQ
How long does Blueberry Auto take from seed to harvest?
Dutch Passion lists 8-10 weeks from germination to harvest, which makes it one of the fastest autoflowers in the range. There is no need to change the light schedule to start flowering.
What light schedule should I use for Blueberry Auto?
As an autoflower she flowers on her own, so keep one schedule from start to finish. Most indoor growers use 18/6 or 20/4. Outdoors she simply runs on natural daylight, whatever the season.
How tall does Blueberry Auto grow?
Most plants stay around 50-75 cm (19.7-29.5 in). Only in exceptional conditions, for example in a hydro system, do they pass 100 cm (39 in). That compact size suits small tents, balconies and discreet outdoor spots.
What yield can I expect from Blueberry Auto?
Indoors, 350-500 g/m² (1.15-1.64 oz/ft²) is possible. Around 50 g (1.8 oz) per plant is typical for home growers, while a strong LED and hydro can produce more than 200 g (7.1 oz) per plant. Outdoors, expect about 25-75 g (0.9-2.6 oz) per plant.
Is Blueberry Auto suitable for beginners?
Yes. She is robust, tolerant of less than perfect conditions and needs no special techniques. Soil or coco is an easy starting point for a first autoflower grow.
What does the Blueberry Auto high feel like?
It is an Indica-dominant effect that sits mainly in the body. Expect strong physical relaxation and a calm, comfortable mood that lasts a few hours, best enjoyed in the evening.
