Mataro Blue is Kannabia Seed Company’s child of a difficult three-way cross between Blueberry, Mazar-i-Sharif, and Black Domina. The strongly indica-dominant high is mellow and provides a long-lasting combination of calm, uplifting euphoria with physical relaxation. Great for easing anxiety and stress, Mataro Blue won’t overwhelm the inexperienced user. It also won’t overwhelm the inexperienced grower, and is a good choice for those wanting to try their hand at growing their own medicine. When grown in colder conditions, the ripened flowers can turn a beautiful purplish-blue.

Cultivation Info | Vetted methods to get the best from your bud

  • Indoor flowering time: 58-65 days - Kannabia Seeds
  • Indoor yield: 600 g/m2
  • Outdoor yield: 800 g/plant
  • Harvest time: (Outdoor/Greenhouse) Late September to early October

The plant forms a thick central bud, hardening because of the number of flowers that form overlapping bunches. The plant starts to form crystals as soon as it begins to flower, eventually becoming covered in a thick coat of sticky resin, like large drops of caramel. It immediately produces trichomes with lime-green heads, and by the time it has nearly finished it has a whitish/golden appearance with a penetrating smell. When subjected to low temperatures the colour turns a bluish purple. It forms thick, healthy cuttings that are suitable for cloning. Median nodes develop with huge, fat leaves. It withstands large amounts of fertiliser when growing and is resistant to periods of drought very well. Indoors we recommend using a lot of wattage to optimise the crop’s results (800W/m2). The recommended vegetative cycle indoors is two weeks for a good yield. With hydroponic systems the results are particularly impressive and quick to ripen. It works very well outdoors, occupying a circumference of several square metres. We recommend propping it well to support the weight of the buds. With good pruning, the plants will grow into large bushes up to 2 m tall. The flowering cycle is 58-65 days, so it will be ready for harvesting in early September. We recommend using carbohydrates to bring out all the flavour. The smell is very deep, with a hint of bitter orange.

Flowering cycle: 58-65 days. Production: 600 gr/m2. Harvest: September-October. Medium height: 200 cm. Production: 800 gr/plant.

Additional Information

The most difficult genotype in our entire catalogue is a three-way cross featuring the best of several predominantly indica strains. One of these is one of the most indica-rich Blueberries that we have, with a very high yield and maintaining all the properties that this variety is known for (short height, fast flowering and a bluish tone). Another of the components is an original Afghan (Mazar-i-Sharif), a very good resin producer that also gives a generous harvest. The final ingredient in this indica cocktail is our Black Domina, which gives it a more ramified structure when grown outdoors or indoors in seven-to-ten-litre pots, and more height than the results of the first crosses.

Mataró Blue is the most popular strain from Kannabia Seeds in Europe. The reason for the popularity of Mataró Blue lies in it's amazing genetics. Kannabia Seeds used a special genetic selection of Blueberry, original Afghan (Mazar-i-Sharif) and Black Domina. What a Dream Team… The name of this strain is a combination from Kannabia's place of birth (Mataró, Spain) and the characteristic of this strain to become bluish of color. Especially when grown in a cold climate, the plant may become electric blue. The Mataró Blue is an Indica-dominant strain, it's easy to grow and the yield of this plant is very generous.
