Known for an intense sweet blueberry aroma, the characteristic blue and violet colours in cool conditions and a deeply relaxing effect. A Cannabis Cup winner and a reference for fruity indica genetics. - **Shishkaberry** — a Blueberry descendant, known for even more intense berry profiles, higher THC potency and a compact, bushy structure — ideal for indoor growing. The result: **Blue Pyramid** — **26% THC**, the most intense Blueberry berry profile, blue and violet colouring under cool conditions and deep body relaxation in just **48 days under LED**. The **Blue Pyramid strain** is one of the few European indica lines to pair true Blueberry genetics with this level of potency. ## A blue cannabis strain — what's behind the colour? The unusual blue and violet tones come from **anthocyanins** — natural plant pigments activated at lower temperatures in flowering. Blue Pyramid has a genetic predisposition for this colouring from the Blueberry line: - Lower the temperature in the last 2 weeks of flowering to **16–18 °C at night** - Blue, violet and purple-red tones develop on leaves and flowers - The colour does not affect aroma or effect — it is an aesthetic feature of the genetics ## Aroma and terpene profile Terpene | Typical impressions | Contribution to the profile **Myrcene** | Earthy, fruity, sweet | The carrier of indica depth — the Blueberry base **Linalool** | Floral, sweet, creamy | The sweet berry note — the Blueberry character **Caryophyllene** | Spicy, warm | Spicy depth beneath the fruity profile ## Blue Pyramid vs Auto Blue Pyramid: a direct comparison | Blue Pyramid Fem | Auto Blue Pyramid **Genetics** | Blueberry × Shishkaberry | Blueberry (Auto) **Seed type** | Photoperiod | Autoflowering **THC** | **26%** | 22–24% **Flowering (LED)** | **48 days** | 53 days **Yield (LED)** | **800–900 g/1.5 m²** | 700–750 g/1.5 m² **Best for** | Highest potency, Shishkaberry strength | No light schedule, multiple harvests Blue Pyramid is also part of **Power Mix Fruit** — 12 feminized seeds from 4 fruity-aromatic genetics in one pack. ## Blue Pyramid family — all variants - **Blue Pyramid Fem** — photoperiod, 48 days LED, 26% THC, Blueberry × Shishkaberry - **Auto Blue Pyramid** — autoflowering, 53 days LED, 22–24% THC - **Purple Urkle × Blue Pyramid** — Gold Line, Purple Urkle × Blue Pyramid cross **A true blue Blueberry genetic.** Blue Pyramid delivers 26% THC, an intense berry profile and blue-violet buds in just 48 days.

Rare & Purple Strains Bulk Seeds Blue Pyramid — frequently asked questions **What is Blue Pyramid?** Blue Pyramid is a feminized 80% indica by Pyramid Seeds based on Blueberry × Shishkaberry — with 26% THC, a 48-day LED flowering time, an intense blueberry-berry profile and unusual blue colouring. **Is Blue Pyramid a Blueberry strain?** Blue Pyramid is based on Blueberry — DJ Short's cult classic — as its parent line. The characteristic blueberry-berry profile and blue colours come directly from the Blueberry genetics. At 26% THC it's clearly stronger than classic Blueberry lines (typically 17–20%). **Why does Blue Pyramid turn blue and violet?** The colour comes from anthocyanins — natural plant pigments from the Blueberry genetics. At night temperatures of 16–18 °C in the last two weeks of flowering, blue, violet and purple-red tones develop on leaves and flowers. **What is Shishkaberry?** Shishkaberry is a Blueberry descendant known for more intense berry profiles, higher potency and a compact indoor-friendly structure. In Blue Pyramid, Shishkaberry delivers the higher THC potency (26%) and reinforces the berry profile of the Blueberry base. **How long does Blue Pyramid flower?** 48 days under LED, 55 days under HPS. Outdoor harvest in the 1st–2nd week of September in the northern hemisphere. **Where can I buy Blue Pyramid seeds?** Original Blue Pyramid seeds with a germination guarantee are available directly from Pyramid Seeds — also in bulk packs, with fast, discreet worldwide shipping.
