Auto Blueberry

If you want to enjoy the Blueberry experience with the speed, ease and convince of autoflower seeds then Auto Blueberry seeds are the perfect choice! Auto Blueberry is one of the fastest growing strains in the Dutch Passion seed collection. She can grow from seed to harvest in as little as 8 weeks, though 9-10 weeks may be more typical. The buds from Auto Blueberry have the same relaxing body effect, delicious taste and pleasurable appeal as the photoperiod version.

Auto Blackberry Kush

Auto Blackberry Kush produces frosty, powerful buds with Grade-A bag appeal, especially from the deep blue/purple phenotypes. The combination of intense autumnal colours below a shimmering layer of THC-rich trichomes never loses its appeal! This indica autoflower was created by crossing Blueberry with a dark hash plant.

Just like Auto Blueberry this is another rapid blue autoflower strain. She can grow from seed to harvest in as little as 9 weeks, though experienced auto growers may prefer to wait a week or so longer to allow the blooms to swell to maximum size and develop a heavier effect.

Blue Auto Mazar

Blue Auto Mazar is a delicious combination of original Afghani Auto Mazar genetics with the sweet fruity Auto Blueberry. She grows from seed to harvest in around 70 days and may show blue and purple hues in the buds, especially in cooler grow room conditions during bloom. Yields can be XL, especially in the hands of experienced growers with optimised grow rooms. THC levels are very high, the indica effects are satisfying and sedating. Like the rest of the blue strain autoflowers, Blue Auto Mazar also grows very well outdoors. Just select a warm and sunny 3 month period.

Where do the blue cannabis genetics come from?

Blueberry genetics were originally created from a blend of Mexican, Thai and (mainly) Afghani genes. The unique indica genetics deliver the trademark relaxation and pleasure aspects to the powerful effects. The hint of sativa genetics ensures a hugely enjoyable cerebral quality to the high. They were created by DJ Short and adopted by Dutch Passion in a cooperation with the Canadian breeder. These are some of the most popular cannabis genetics ever created.

What is the average yield of blue cannabis strains seeds?

Blueberry is an average yielding strain, she is grown for quality rather than quantity. However the autoflower blue strains (Auto Blueberry, Auto Blackberry Kush, Blue Auto Mazar) grow from seed to harvest under 20 hours of indoor light allowing them the extravagant XL yields typical of all Dutch Passion autoflower strains.

What is the average flowering time for blue cannabis strains?

The indica dominant genetics lend themselves to fast bloom times. The photoperiod version of Blueberry typically takes around 8 weeks to bloom. The autoflowering blue strains have often completed their grow cycle after about 70 days of growth. They may even finish earlier than that!

What is the average THC content in blue weed strains?

A lot depends on the grow conditions, type of light, nutrient management, grower experience etc. Well grown blue strains contain around 20% THC in the hands of a skilled hobby grower. Grown in professional conditions with UVB etc, blue strains may well deliver over 20% THC.

What are the differences between Blue Auto Mazar and Auto Mazar?

Blue Auto Mazar was created by crossing two legendary genetic lines, Auto Blueberry and Auto Mazar. The result carries the rich afghani hash taste from Auto Mazar and combines it with the sweet fruity berry flavours from Auto Blueberry. A truly delicious cannabis combo! THC levels are predictably very high and the exotic taste combination makes Blue Auto Mazar a popular (and easy to grow!) choice.

Blue Cannabis Strains

Blue marijuana strains get their extraordinary colour as the buds begin to appear and they’re much prized by experienced growers both for their unusual colouring and the high quality of the harvest.

The intensity of the blue hues varies considerably between different blue strains and the growing conditions are also an important factor in the level of colour. Plants that are exposed to slightly colder air in the later stages of their growth cycle tend to produce the most vivid blues.

The first blue strain that achieved wide commercial success was Blueberry , developed in the Netherlands in the late 1970s. Its reputation as a premiere weed was sealed in 2000, when it won first place in the High Times Cannabis Cup. Blueberry is an Indica dominant hybrid of plants from Thailand and Oaxaca in southern Mexico, and gives an intense, euphoric hit.

It’s widely prescribed by medical cannabis dispensaries in the USA for muscular pain relief, stress and nausea. Blueberry Widow is another popular blue type and it’s a crossbreeding of Blueberry and White Widow, both of which have been previous winners of the High Times Cannabis Cup. It gives a clear-headed stone with visual effects and, as the plant matures, the leaves and buds take on deepening shades of both blue and sometimes purple.

Blue Mystic is a highly respected strain from California and it’s the product of crossing Blueberry with another venerable stalwart of the weed world, Northern Lights . It’s a potent weed that gives a strong body stone combined with a powerfully narcotic high. The plants take on a noticeably blue colour as they start to flower, and the large buds have a velvety look.

Blue Weed Seeds

Northern Light Blue is the result of crossing our special Northern Light mother with an original clone of the authentic Blueberry of DJ Short. We obtain this strain of exceptional qualities, which gives a twist to two of the most famous indicas in the world.

It is a strain with a very dense foliage and a compact growth. But do not be fooled, because it is a plant that can reach considerable sizes indoors and outdoors, and exceed in size to plants with a higher load of sativa in their genes. It tolerates very well any cultivation method or technique, such as pruning, SCROG, Sea Of Green, etc. It produces thick and very strong secondary branches to support the big flowers.

The buds give off a very intense and pleasant aroma. They have a sweet fragrance but a little sour, like strawberry or fruits of the forest. The taste is also intense, a bit sweet and sour. It reminds of cherries or even grapes, but with hints of incense and pine. It is a plant with a complex flavor, to which new nuances are found with each puff. Naturally, this will be enhanced in vaporized consumption.

The effect of this strain is markedly relaxing, although it is not at all narcotic, so it does not become annoying if we are going to perform any task, whether physical or mental. It can be said that it is an effect without contraindications.
