How to grow Auto Blueberry Kush – Expert tips

Get the most out of your grow with this concise, phase-by-phase guide based on genetics and real grower feedback.

Quick overview: Autoflowering · Nirvana · 8–10 week cycle · Low-maintenance · Ideal for indoor tents, balconies, or cold climates.

Safe start: Germinate in a warm, dark place (22–25 °C) with high humidity. Transplant once the taproot is ~1 cm long. For a stronger start, SeedBooster Plus germination stimulator boosts root development and reduces shock.

Stable seedling: Keep lights 30–50 cm (11.8–19.7 in) above canopy. Water lightly and use well-aerated soil. Mygal (Mycorrhizal gel) enhances root absorption and protects against stress.

Directed growth: Maintain 18–20 h light daily. Use 18–27 L pots for full development. Train with LST after week 3 to expose lower buds. Avoid aggressive pruning—this auto hates stress.

Efficient flowering: From week 4, buds begin forming. Lower humidity to 40–50% to prevent mold. Support heavy colas if needed. Sensi Bloom A+B Advanced Nutrients maximizes resin and yield during peak bloom.

Harvest and refinement: Harvest when 70% of trichomes are milky with some amber. Flush 7–10 days before. Dry at 18–22 °C and 50–60% RH. Cure for 2–4 weeks to enhance flavor and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I first grew Auto Blueberry Kush during a rainy Dutch summer—my balcony was damp, cold, and packed with other plants. I almost didn’t bother, thinking it’d get moldy or stretch out. But this thing? It stood tall, stayed compact, and smelled like a berry bomb. I used a simple 20L pot and basic nutrients, and still pulled 410 g/m². The high hit fast: a full-body melt with just enough head buzz to keep me present. I’ve since recommended it to friends who are just starting—no drama, no fuss, just results. For me, it’s the perfect chill-out strain. I keep a jar for late nights, and honestly, it’s become my go-to when I need to unwind without passing out. If you want power, speed, and flavor in one discreet package, this is it.
