Mataró Blue Cannabis Seeds by Kannabia
Mataró Blue is a feminised cannabis seed from Kannabia that crosses three heavyweight genetics — Blueberry, Mazar-i-Sharif (the original ancient Afghani landrace), and Black Domina — into one resin-drenched indica-dominant plant. The result is a strain that hash makers and flower connoisseurs both chase season after season. If you want to buy a plant that stacks heavy, frosty nugs from main cola to the lowest side branch, this is where you start.
Why Mataró Blue Deserves a Spot in Your Garden
Mataró Blue produces up to 600g per square metre indoors and up to 800g per plant outdoors, making it one of the highest-yielding indica-dominant feminised seeds in the Kannabia catalogue. Kannabia didn't just throw three strains together and hope for the best. This seed is the product of deliberate lab work — Blueberry brings the colour and flavour depth, Mazar-i-Sharif contributes that ancient Afghan resin production and stone-heavy structure, and Black Domina (Kannabia's own cut) adds vigour and density. The combination produces a plant that's almost comically covered in trichomes. We're not exaggerating when we say you'll see the crystal coverage before you see the leaves underneath.
What makes this one stand out from other indica-dominant seeds in the catalogue? Yield and resin, full stop. Those numbers come from Kannabia's own grow data and are backed up by grower reports across forums and seed banks alike. The buds develop into massive, dense nugs that genuinely need branch reinforcement in late flower. If you've ever had a branch snap under bud weight, you know the heartbreak. Stake her or use a trellis net — don't learn the hard way.
The one honest limitation: she smells. A lot. During late flowering, the terpene output gets intense — sweet, earthy, with that unmistakable Blueberry funk cutting through. Indoors without a decent carbon filter and extraction fan, your neighbours will know exactly what you're growing. Good ventilation isn't optional here; it's the price of admission for a plant this productive.

Flavour, Aroma, and Resin Profile
Mataró Blue delivers a layered terpene profile of deep berry sweetness from its Blueberry parent, over a thick, earthy, almost spicy base inherited from Mazar-i-Sharif. Crack open a cured bud and you get an immediate hit of that complexity — it fills a room. The taste follows the nose: sweet and fruity on the inhale, with a hashy, slightly floral finish that lingers. Connoisseurs who've grown tired of one-dimensional strains tend to come back to this one specifically for that depth.
And then there's the resin. This is one of those strains that makes you understand why people make hash. The trichome coverage is dense, milky, and extends well beyond the buds onto sugar leaves and even small fan leaves near the colas. If you've got a set of bubble bags or a rosin press, this plant was practically bred for you. The hash yield from a single harvest can be genuinely surprising — Kannabia themselves market this strain as one of their best for extractions, and we'd agree.
How to Grow Mataró Blue Seeds
Mataró Blue grows best with low-stress training during veg, sturdy plant reinforcement from mid-flower, and a carbon filter running at full capacity for the final weeks. Follow these steps for a successful harvest:
- Germinate your feminised seeds using the paper towel method or directly in a small pot of moist, light soil mix. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final containers once they've developed 2–3 sets of true leaves. She grows bushy, so give each plant enough space — at least 50cm between plants indoors.
- During vegetative growth, keep humidity around 60–70% and temperatures between 20–26°C. She responds well to low-stress training (LST) to open up the canopy and expose lower bud sites to light.
- Switch to a 12/12 light cycle to trigger flowering. Expect her to stretch moderately in the first two weeks of flower before bud development takes over.
- From mid-flowering onward, install bamboo stakes, a SCROG net, or yo-yo hangers. The main cola and side branches will develop nugs heavy enough to snap unsupported stems.
- Increase airflow and run your carbon filter at full capacity during weeks 5–8 of flower. The terpene output gets serious, and without proper extraction, odour will escape.
- Harvest when trichomes shift from clear to milky-white with some amber. For a more cerebral effect, harvest earlier in the window; for a heavier, deeper stone, let more trichomes turn amber.
- Dry in a dark, ventilated space at around 18–20°C and 50–55% humidity for 10–14 days, then cure in glass jars for at least two weeks. The Blueberry flavour really develops during a proper cure.
Mataró Blue Compared to Similar Kannabia Strains
Mataró Blue outperforms Kritikal-K and Gypsy Kush on resin production and terpene complexity, while Kritikal-K edges ahead on raw flower weight. Here's the full comparison:
| Feature | Mataró Blue | Kritikal-K | Gypsy Kush |
|---|---|---|---|
| Genetics | Blueberry x Mazar-i-Sharif x Black Domina | Critical Mass lineage | Kush-dominant hybrid |
| Dominant Type | Indica-dominant | Indica-dominant | Indica-dominant |
| Indoor Yield | Up to 600g/m² | High | Moderate-High |
| Resin Production | Very high | High | Moderate |
| Flavour Profile | Berry, earthy, hashy | Sweet, citrus | Earthy, Kush, pine |
| Best For | Hash making, flavour chasers | Maximum flower yield | Classic Kush fans |
We'd pick Mataró Blue over Kritikal-K if resin production and flavour depth are your priorities. If you're purely chasing flower weight and don't plan on making hash, Kritikal-K edges ahead. Gypsy Kush is the pick for growers who want that old-school Kush terp profile without the Blueberry sweetness.
What Makes This Strain a Hash Maker's Favourite
Mataró Blue is one of the most extraction-friendly feminised seeds available, thanks to its Mazar-i-Sharif backbone — a landrace used for traditional hashish production in Afghanistan for centuries. According to the EMCDDA's reporting on traditional cannabis resin production regions, the Afghan Hindu Kush corridor remains one of the world's primary sources of high-quality hashish genetics, and Mazar-i-Sharif sits right in that heartland. Cross that with Blueberry's flavour genetics and Black Domina's vigour, and you get a modern plant with old-world hash credentials.
Whether you're running ice water extraction, dry sifting, or pressing rosin, the return from this strain is consistently above average. The trichome heads are large, well-formed, and separate cleanly — exactly what you want. And because the terpene content is so high, the resulting hash or rosin retains that berry-earth flavour profile rather than tasting like generic plant wax. Kannabia has won awards with this strain for good reason.
Growing Mataró Blue indoors? Her bushy growth and heavy buds make a SCROG net almost mandatory — pair her with a sturdy trellis net to keep those colas upright. A carbon filter and inline extraction fan are non-negotiable for odour control during late flower. If you're planning to press hash or rosin from the harvest, pick up a set of bubble bags or a rosin press to make the most of that ridiculous trichome coverage. You can buy all of these accessories alongside your seeds at Azarius.
Frequently Asked Questions
What flavours and aromas does Mataró Blue produce?
Deep berry sweetness from the Blueberry parent, layered over earthy, spicy notes from the Mazar-i-Sharif genetics. The finish is hashy and slightly floral. The smell intensifies dramatically during the last few weeks of flowering — a carbon filter is strongly recommended for indoor grows.
Is Mataró Blue indica or sativa dominant?
Indica-dominant. All three parent strains — Blueberry, Mazar-i-Sharif, and Black Domina — lean heavily indica. Expect a bushy growth pattern, dense bud structure, and a deep, relaxing experience rather than anything racy or cerebral.
How tall does Mataró Blue grow?
Up to around 2 metres, depending on conditions. She grows bushy rather than tall, with strong lateral branching. Indoor growers can manage height with topping and LST during veg. Outdoors with no training, she'll fill out wide before she stretches up.
Does Mataró Blue need reinforcement during flowering?
Yes. The main cola and side branch nugs get genuinely heavy — heavy enough to snap branches if left without reinforcement. Use bamboo stakes, a trellis net, or yo-yo plant hangers from mid-flowering onward. This isn't a "nice to have" — it's essential.
Is Mataró Blue good for making hash or rosin?
It's one of the best strains in the Kannabia catalogue for extractions. The trichome coverage is extremely dense, the heads are large and separate cleanly during ice water or dry sift processing, and the terpene profile survives extraction well. If hash making is your goal, this strain should be near the top of your list.
What yield can I expect from Mataró Blue indoors?
Up to 600g per square metre under optimised indoor conditions. Outdoors, she can push up to 800g per plant. These are upper-end figures — actual yield depends on light intensity, pot size, nutrients, and training technique. Even average growers report above-average harvests with this strain.
How many seeds come in a pack of Mataró Blue?
Each pack contains 5 feminised seeds.
