Quick read: 20-25% THC, 100-180cm mature height, 9-11 weeks bloom. Genetics: Mataro Blue (Kannabia Seeds). Difficulty: moderate.

Lineage: Mataro Blue comes out of Kannabia Seeds' breeding program in Granada, Spain — a fully feminized indica that leans on stabilized stock rather than marketing hype. The numbers hold up in practice: growers pulling 400–500 g/m² indoors over a 9–11 week flower window, with finished material testing between 20–25% THC. It's a moderate-difficulty grow, meaning you'll want a couple of runs under your belt before committing a full tent to it, but it won't punish small mistakes the way some high-THC indicas do. Expect the canopy to stay manageable — useful if you're working within a licensed home-grow space under the Cannabis Act's four-plant limit.

Cure it properly and the fruity, sweet, and earthy profile comes through clearly, without the harshness that sometimes plagues fast-dried indica flowers. Best suited to intermediate growers who want a reliable indoor yield and a well-documented genetic background rather than an unknown clone cut.

Genetics & Lineage

Mataro Blue traces its genetics to Mataro Blue (Kannabia Seeds). This indica-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Kannabia Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Mataro Blue delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Mataro Blue

Mataro Blue is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-11 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Mataro Blue features a fruity, sweet, earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Mataro Blue is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Mataro Blue?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
