Few strains carry as much history in a single name as Blueberry. Dutch Passion brought this DJ Short original from the 1970s to the Dutch market in 1998, and these feminized seeds put that classic line within easy reach of home growers who want every plant in the room to be a flowering female. Expect a mostly Indica plant, roughly 80% Indica and 20% Sativa, with an unmistakable berry nose and buds that can blush blue and purple late in bloom.
The lineage is a three-way blend built mainly on Afghani Indica, with Thai Sativa and a smaller dose of Oaxacan (Mexican) Sativa giving the high its lift. Blueberry later became a parent of modern favorites such as Blue Dream, Blueberry Headband and Blue Cookies.
The trophy shelf backs up the reputation: Blueberry took 1st Prize at the High Times Cannabis Cup 2000 and 3rd Prize at the High Times Cannabis Cup 2001, only a couple of years after release. Dutch Passion rates its THC as very high, and levels around 20% are nothing unusual.
Indoors, plan on 350-450 g/m² (1.15-1.47 oz/ft²) after a flowering period of roughly 8-9 weeks. Outdoors in a mild, sunny climate she can reach 250-300 cm (98-118 in) and is usually ready in early to mid fall.
Flavor, Effects, and That Famous Blue Color
Open a jar of properly cured Blueberry and the first impression is ripe, sweet blueberries, so close to the real fruit that it often surprises first-timers. The flavor follows the nose: candy-like, juicy and smooth, the kind of smoke or vapor that keeps you coming back for one more taste.
The buds are compact and heavily frosted, with a coat of white trichomes that Dutch Passion compares to the look of White Widow. Add the blue and purple tones that cool nights can bring out and you get serious bag appeal. A favorable calyx-to-leaf ratio also makes manicuring quicker than with many leafy Indicas.
Despite the Indica dominance, the high is not a heavy knockout. The Sativa share keeps the mind clear, upbeat and euphoric, while the body settles into a warm, feel-good comfort. It is strong and long-lasting without flattening experienced users, so many fans enjoy it by day as well as at night.
Growing Blueberry Feminized Seeds
Blueberry rewards growers who keep conditions steady. She can be a fussy feeder, so dial in climate, nutrients, medium and lighting before flowering starts. About 4 weeks of vegetative growth suits a dense room with many plants per square meter, while 6 weeks makes more sense for a few larger plants. Including the 8-9 week bloom, the whole cycle runs around 12-15 weeks from seed to harvest.
Plants grow sturdy, with thick stems, broad fan leaves and short internodes that pack the colas tight. That compact frame makes her a natural fit for Sea of Green, although some stretch in early flower is normal thanks to the Sativa side of the family. Stems may turn purple as she matures.
To push the colors, let some cooler air into the grow room during the last part of bloom. Outdoors she wants a temperate climate with plenty of sun and a breeze to keep dense buds dry; in ideal conditions some growers have harvested more than 2 kg (70.5 oz) from a single plant.

FAQ
Is Blueberry feminized an Indica or a Sativa?
It is roughly 80% Indica and 20% Sativa. The Afghani backbone gives a compact plant with dense buds, while the Thai and Oaxacan Sativa genetics keep the high clear and euphoric rather than sleepy.
How long does Blueberry take to flower?
Expect about 8-9 weeks of flowering indoors. With the recommended 4-6 weeks of vegetative growth, the full cycle takes around 12-15 weeks from seed to harvest. Outdoors she is usually ready in early to mid fall.
What yield can I expect from Blueberry feminized seeds?
Indoors, 350-450 g/m² (1.15-1.47 oz/ft²) is realistic in optimized conditions. Outdoors in a mild, sunny climate plants can get big, and some growers have harvested more than 2 kg (70.5 oz) from a single plant.
Is Blueberry a good strain for beginners?
She suits growers with a bit of experience best. Blueberry can be a fussy feeder and performs at her peak in a stable environment. Get the climate, nutrients and lighting right and the quality of the harvest is outstanding.
How do I bring out the blue and purple colors?
Cooler temperatures toward the end of flowering encourage the blue and purple hues. Indoors, letting some cooler air into the room during the final weeks of bloom is the easiest way to trigger them.
