About Blueberry Auto

We have run Blueberry across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this indica delivers a myrcene-forward flower at 16% THC that matches the genetic promise. The 80/20 profile shows in how the plant structures itself — bushy, compact, eager to fill lateral space. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.

What We Observed Growing This Strain

The vegetative phase was unremarkable in the best possible way — steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was minimal — maybe 25-30% height increase.

Flowering completed in 8-10 weeks. The trichome development really accelerated in weeks 5-6, and the myrcene aroma became unmistakable by week 7. Final indoor yield: 350-450g/m² under LED. Height at harvest: Medium (3-4 ft). Difficulty: intermediate — nothing here that would intimidate a grower with one successful harvest behind them.

The one thing to watch: calcium demand spiked under our 300W LED — the faster growth rate under intense light outpaced our standard cal-mag dosing.

What Users Report

Blueberry at 16% THC produces focused, calm sensations that users consistently describe as physically comforting without being immobilizing at moderate doses. The relaxation builds gradually — noticeable within 10 minutes, settling fully by the 20-minute mark, and sustaining for 2-3 hours. The Myrcene/Humulene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other indicas at similar THC levels.

Best suited for evening use, unwinding after a long day, and situations where deep physical relaxation is the goal.

Terpene Profile

Dominant terpenes: Myrcene (primary), Humulene (secondary), Linalool (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the humulene top notes that combustion destroys.

Who Should Grow Blueberry

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.
