Auto Galaxy Autoflowering Seeds – Pyramid Seeds · High THC, Minty Flavor & Fast Harvest

Auto Galaxy by Pyramid Seeds is a top-tier autoflowering strain that delivers big flavor, serious potency, and heavy yields without the hassle — perfect for both new and experienced growers who want quality without compromise.

Feeling lost in the jungle of cannabis strains, not knowing where to start or which steps actually matter? You’re not alone. Many growers jump in blind, only to end up with weak plants, poor yields, or buds that just don’t hit right — not because they’re bad at growing, but because they never had a clear roadmap.

Without guidance, it’s easy to overwater, misjudge lighting, or harvest too early. You might even think the seeds are faulty when really, it’s just a missing step. That confusion kills motivation and wastes time and money.

Auto Galaxy changes the game. With its stable genetics and predictable growth cycle, this strain gives you a phase-by-phase path from seed to harvest — no guesswork, no stress. Just follow the flow and watch your plant thrive.

Preparation

Get your setup ready before germination to avoid last-minute stress.

• Choose a well-draining, airy substrate like coco or light soil.
• Set up your 18–20 h light cycle with LED or HPS.
• Ensure temperatures stay between 22–26 °C (71.6–78.8 °F).
• Use pots of 18–27 L (6.34–7.15 gal) to avoid transplanting.
• Check pH levels: 6.0–6.5 for soil, 5.8–6.2 for coco.

Start

Begin strong with the right germination and early care.

1. Germinate seeds in a damp paper towel or directly in soil at 22–25 °C (71.6–77 °F).
2. Transplant once the radicle is ~1 cm (0.39 in) long.
3. Water lightly — keep the medium moist but not soggy.
4. Introduce mild nutrients after the first true leaves appear.
5. Boost root development with Voodoo Juice for faster establishment.

Veg

Build a strong foundation for massive yields.

1. Maintain 18–20 h of light daily — no changes needed.
2. Water when the top inch of soil feels dry.
3. Apply Sensi Grow A+B to support healthy leaf and stem growth.
4. Use low-stress training (LST) to open up the canopy.
5. Avoid topping — autoflowers don’t recover well from aggressive pruning.

Flower

Maximize resin and bud density during flowering.

1. Expect flowering to start automatically around week 3–4.
2. Reduce humidity to 40–50% to prevent mold.
3. Increase airflow with oscillating fans and exhausts.
4. Switch to bloom nutrients like Sensi Bloom A+B at the first signs of pre-flowers.
5. Add a PK booster in weeks 4–5 to boost flower development.
6. Look for milky trichomes — that’s your peak harvest window.

Harvest

Finish strong and preserve quality.

• Flush your plant 7–10 days before harvest to improve taste.
• Cut branches and hang them upside down in a dark, cool room.
• Dry at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 7–10 days.
• Cure buds in jars for 2–4 weeks, opening daily to release moisture.
• Store in airtight containers away from light and heat.

Why follow this flow instead of winging it?

• Consistent, high-quality harvests every time
• Fewer mistakes and wasted resources
• Better control over plant size and yield
• Maximized resin and flavor development
• Reduced risk of mold and pests
• Confidence in every grow cycle
• More enjoyment from start to finish

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Auto Galaxy three times now, and it’s become my go-to for quick, reliable harvests. The first time, I made the mistake of using a small pot — it stunted the plant. Second time, I topped it, and it barely recovered. Lesson learned: let it grow naturally. Now I use a 25 L (6.6 gal) pot, 20 h of light, and Voodoo Juice from day one. The buds are dense, frosty, and smell like fresh mint. I harvest around day 80, when most trichomes are milky. The high is smooth — body relaxation with a touch of mental clarity. Perfect for unwinding after a long day.
