Northern Light x Blueberry Auto Auto-Fem

Northern Light x Blueberry Auto feminized seeds combine two of the most reliable indica genetics in autoflowering cannabis into a single third-generation automatic plant. Compact, fast, and dense with resin, this strain finishes from seed to harvest in under 75 days and delivers yields between 400 and 450 g/m² indoors without requiring any light schedule adjustments. Bred by P.P.S., these seeds are fully feminized, meaning virtually every plant will flower as a female with no intervention required.

Genetics & Lineage

The lineage traces back to Northern Light Blue Auto crossed with Blueberry Auto, two established autoflowering indica-dominant varieties. Northern Light contributes its structural stability, compact internodal spacing, and heavy resin production — traits refined over decades of selective breeding. Blueberry, originally developed by DJ Short, brings the fruity terpene profile and a deeply relaxing body effect. The result is an indica-dominant hybrid with a genetics ratio of approximately 70% indica and 30% sativa, stabilized across multiple autoflowering generations for consistent expression. The ruderalis component is well-integrated at this generation, meaning plants retain the yield and potency associated with photoperiod indica strains while flowering automatically regardless of light cycle.

Aroma, Flavour & Effects

The dominant terpenes are Myrcene, Limonene, and Linalool. Myrcene leads the profile, producing the earthy, musky base characteristic of indica-heavy strains and contributing to the physical depth of the effect. Limonene adds a bright, citrus-edged lift to the aroma that keeps the scent from reading as purely dank, while Linalool brings a soft floral quality that rounds out the finish. On the nose, fresh buds read as blueberry jam layered over a herbal, lightly piney foundation. The flavour on inhale follows closely — sweet fruit up front with an earthy, slightly spiced exhale. Effects onset within minutes and are predominantly physical: a full-body relaxation that builds steadily without a sharp sedative drop. THC content sits in the moderate-to-high range consistent with its parent genetics, making it manageable for most users while still delivering noticeable relief.

Growing Profile

Plants reach an average height of 70 cm indoors, making this strain well-suited to grow tents and low-headroom spaces. The structure is characteristic Northern Light — a pronounced central cola supported by numerous compact lateral branches, all producing dense, resinous buds covered in a heavy trichome layer. Total grow time from germination to harvest is approximately 70 to 75 days. Indoor yields average 400 to 450 g/m² under optimised conditions. Outdoor plants can be harvested in as little as 10 weeks from seed, with yield dependent on pot size and season length. The strain shows strong resistance to mould and environmental fluctuation, which makes it forgiving during temperature swings or humidity variation. Low-stress training techniques such as LST can be applied in the first two to three weeks to improve light distribution across lateral branches, though the plant performs well without any training at all.

Who This Strain Is For

Beginners will appreciate the autoflowering format, the resilience, and the straightforward grow cycle — there is no need to manage light schedules or worry about accidental revegging. Experienced growers running multiple cycles per year will value the fast turnaround and consistent output. The effect profile suits evening or end-of-day use, making it a practical choice for those seeking physical relaxation, stress relief, or support with sleep without a heavily sedating onset. A discreet indoor setup with a 600W HPS or comparable LED is sufficient to reach maximum yield potential.

Northern Light x Blueberry Auto delivers what its genetics promise: a fast, reliable, resinous indica with genuine flavour depth and a yield that justifies the space it occupies.
