How to grow Blueberry Bubblegum Auto Sensi Seeds

Quick overview: autoflowering · Sensi Seeds · 75–85 day cycle · low difficulty · ideal for indoor tents or outdoor gardens in temperate climates.

Safe start: Germinate in a moist environment at 22–25 °C. Transplant carefully when the taproot is about 1 cm long.

• Use a light, airy medium to prevent overwatering
• Keep humidity high (60–70%) during germination
• Consider Root It 150ml – Rooting gel for faster, stronger root development
• Avoid deep planting — place seed 0.5–1 cm deep
• Water lightly until first true leaves appear

Stable seedling: Focus on root health and steady growth.

• Maintain temperatures between 22–26 °C
• Use mild nutrients or pre-fertilized soil
• Ensure good airflow to prevent damping off
• Apply beneficial microbes like mycorrhizae early
• Keep light intensity moderate to avoid stress

Directed growth: Let the plant develop naturally with minimal intervention.

• Provide 18–20 hours of light daily
• Move to final pot early (18–27 L) to avoid root shock
• Use Pack Top Crop Fertilizer Medium for balanced nutrition
• Apply gentle LST if needed to open canopy
• Avoid topping — autoflowers don’t recover well

Efficient flowering: Support bud development with proper feeding and climate control.

• Lower humidity to 40–50% to prevent mold
• Increase PK nutrients during mid-flower for denser buds
• Use PK 50-30 to boost resin and yield
• Ensure strong airflow around colas
• Monitor trichomes weekly in final weeks

Harvest and refinement: Time it right for maximum flavor and effect.

• Flush with plain water 7–10 days before harvest
• Harvest when most trichomes are milky with some amber
• Dry slowly at 18–22 °C and 50–60% RH
• Cure in jars for 2–4 weeks, burping daily

Personal Experience of Pevgrow’s CEO (Alan)

I grew Blueberry Bubblegum Auto in my 60x60x160 cm tent with a 250W LED and 20L pots. Germination was 100% — all five seeds popped in under 48 hours. I used Root It gel on the first batch, and those seedlings established faster with stronger roots.

By week 4, they were already showing purple hues. I kept it simple: no topping, no SCROG — just gentle LST to spread the canopy. At peak flower, the smell was unreal — like walking into a candy store mixed with a berry farm. I flushed for 10 days and harvested at day 82. Dried and cured, I got 285 g/m² — solid for an auto.

My pro tip? Don’t rush the cure. Let it breathe in the jars for at least three weeks. The flavor deepens, the harshness disappears, and the high becomes smoother. This strain is now a staple in my rotation — fast, tasty, and reliable.
