A Spanish Powerhouse With Proven Roots

Although Pyramid Seeds was officially founded in Barcelona just over a decade ago, its story goes much deeper. Before launching the brand, the core team spent 15 years honing their skills as cannabis cultivators. Their early breeding stock included legendary phenotypes of White Widow, Northern Lights and AK — hand-picked from the best seed banks across Europe.

From the start, Pyramid Seeds focused on refining genetics through continuous test grows and grower feedback, mostly from local Spanish customers. This direct, practical approach resulted in hardy, high-performance strains that didn’t just look good on paper — they consistently delivered under real-world conditions.

One standout from their early line-up, Tutankhamon, remains a fan favourite to this day, often testing upwards of 25–30% THC. It’s a perfect example of what Pyramid does best: familiar names, taken to their highest potential.

Built for Growers, Not Trophies

Unlike many brands chasing cannabis cups, Pyramid Seeds puts breeding first. Their mission? To create vigorous, productive strains that are easy to grow and incredibly rewarding to smoke or vape.

Each new cultivar typically undergoes at least two years of development and refinement before release. That dedication has made Pyramid Seeds a trusted name for growers who want reliability, potency and flavour — not marketing hype. Though they’ve recently started appearing at cannabis expos across Europe, it’s their quietly consistent quality that keeps growers coming back.

Photoperiod or Autoflower? You Get to Choose

Pyramid Seeds takes versatility seriously. Every one of their strains is available in both feminised photoperiod and autoflowering formats. That’s a big win for UK growers facing shorter summers, unpredictable weather or the need for discreet indoor setups.

Autoflowering seeds from Pyramid Seeds aren’t afterthoughts — they’re bred alongside their photoperiod counterparts and deliver comparable quality in terms of yield, potency and terpene richness. For newer growers or those seeking quick results, they offer an ideal entry point into premium cannabis cultivation.

Honest, Reliable, and Hand-Packed

Every Pyramid Seeds pack is assembled by hand. Why? Because the company believes quality control doesn’t end in the breeding room. Each seed is visually inspected for maturity and viability, and strain descriptions are based on real-world growing results — not lab-perfect conditions. If Pyramid Seeds says a plant will finish flowering in 60 days or reach 25% THC, UK growers can trust that it’s achievable in their tents, greenhouses or gardens.
