Worried about male plants ruining your grow? Or inconsistent phenotypes throwing off your entire setup?

That uncertainty can kill your confidence before you even start. You invest time, space, and energy only to end up with weak yields or unusable plants. It’s frustrating, especially when you’re aiming for top-shelf quality.

With the Colección Feminizadas 3, you get guaranteed female genetics from one of Spain’s most respected breeders. Every seed is a step toward a uniform, resin-drenched canopy with minimal effort and maximum control. No guessing, no waste—just predictable excellence.

More Discretion, Fewer Surprises

Feminized seeds mean no accidental males, which keeps your grow space clean, discreet, and efficient. That’s peace of mind from day one. Whether you're growing in a closet or a greenhouse, these strains stay true to type, so you won’t attract unwanted attention with odd smells or irregular growth patterns.

Advanced Seeds uses selective breeding to stabilize genetics, so each plant develops consistently—making it easier to manage odor, height, and harvest timing. Pair that with a compact training routine, and you’ve got a stealthy, high-output operation.

Total Control Over Your Grow

• Guaranteed feminization eliminates 99.9% of male risk, so every seed counts.
• Stable genetics ensure uniform growth—perfect for SCROG or SOG setups.
• High trichome production means more potency and better extraction results.
• Resilient phenotypes handle stress well, from temperature swings to minor nutrient imbalances.
• Clear flowering triggers make timing your harvest predictable and precise.

How to Grow Feminized Strains Successfully

Start right and stay consistent for the best results. These strains thrive when given a solid foundation and a steady hand.

1. Begin with a sterile germination setup using filtered water and a warm environment (22–25 °C).
2. Transplant carefully into well-aerated soil or coco; avoid overwatering seedlings.
3. Use low-stress training (LST) early to shape plants without stress.
4. Switch to 12/12 light cycle to trigger flowering after desired veg time (4–6 weeks).
5. Monitor trichomes and flush 7–10 days before harvest for cleaner smoke.

• Start in 0.5 L pots with light, airy soil.
• Inoculate roots with RootStimulator HY-PRO for faster establishment.

Stable seedling: Build a strong foundation early.

• Keep humidity at 60–70% and light intensity moderate.
• Water lightly—let topsoil dry between irrigations.
• Apply mild organic teas after first true leaves appear.
• Boost root mass with Top Max BioBizz once weekly.

Directed growth: Shape plants for maximum yield.

• Switch to 18/6 light cycle and increase nutrients gradually.
• Use LST to open canopy and expose lower nodes.
• Move to final pot (11–20 L) after 3–4 weeks.
• Support branches with soft ties as they stretch.

Efficient flowering: Lock in quality and density.

• Change to 12/12 light to trigger bloom.
• Maintain RH at 40–50% to prevent mold.
• Feed with bloom-focused nutrients like Sensi Grow A+B Advanced Nutrients.
• Add PK boosters in weeks 4–6 for bigger buds.

Harvest, drying and curing: Finish strong for premium results.

Frequently Asked Questions

Are all seeds in the Colección Feminizadas 3 guaranteed female?

Yes, Advanced Seeds uses advanced breeding techniques to ensure over 99% feminization success. You can expect nearly all seeds to produce female plants.

Can I grow these strains outdoors in a humid climate?

Yes, but ensure good airflow and consider using organic fungicides like Fungone Concentrate as a preventive measure. These strains have moderate mold resistance.

What’s the best way to maximize yield?

Use LST or SCROG training during veg, provide strong light (600W+ HPS or equivalent LED), and feed with quality bloom nutrients. Avoid over-pruning to prevent stress.

Do these strains have strong smells during flowering?

Yes, especially in the last few weeks. Use a carbon filter like those in our Grow Shop to control odor and maintain discretion.

Can I clone these feminized plants?

Absolutely. These stable genetics are excellent for cloning. Take cuttings in early veg and root them with Root It 150ml for best results.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve been growing with Advanced Seeds since my early days, and the Colección Feminizadas 3 is a standout. Last season, I ran Gelato #33 and Slurricane side by side—both exploded in yield and flavor. I used LST to keep them under 1.10 m (3.61 ft) and harvested over 580 g/m² (2.05 oz/ft²) with dense, frosty buds. The aroma filled the room like sweet diesel and berries. I didn’t need to babysit them—just stayed consistent with feeding and airflow. If you want reliable, high-performing genetics without the hype tax, this collection is your move.
