GMO Fast Feminized Seeds – Dutch Passion’s Fast-Flowering Garlic Cookies Hybrid

GMO Fast by Dutch Passion is a fast-flowering feminized cannabis seed that delivers extreme potency, dense resinous buds, and a uniquely pungent garlic-diesel aroma—all ready in just 7–8 weeks of bloom.

Struggling with short growing seasons or impatient for harvest? You’re not alone. Many growers waste time on slow strains that leave them scrambling before autumn rains hit—or worse, stuck with weak yields and bland flavor. The frustration of waiting months only to get mediocre results kills the joy of growing.

That’s where GMO Fast changes the game. Bred from elite Garlic Cookies and Dutch Passion’s own Think Fast, it gives you award-winning genetics with a turbocharged flowering phase—perfect for outdoor guerrilla grows, temperate climates, or indoor stealth setups where time and discretion matter.

Before You Germinate: Prep for Speed & Potency

GMO Fast thrives when you set it up for success from day one. Since it’s a photoperiod strain with fast-flowering traits, it still needs a veg phase—but it won’t waste your time.

• Soak seeds in distilled water at 22–25°C (71.6–77°F) for 24h max.
• Use a light, airy substrate like Monkey Grow Monkey Soil for strong early roots.
• Start in 0.5–1 L pots; transplant once before final container.
• Keep humidity high (60–70%) and light gentle (18/6 cycle) during seedling stage.
• Avoid overwatering—this hybrid hates soggy feet.

During Growth: Fast, Compact & Resilient

GMO Fast stays relatively compact (ideal for SCROG or small tents) and responds well to low-stress training. Its hybrid vigor means it grows steadily without excessive stretching, but it’s not a monster—making it perfect for controlled environments.

Indoors, it typically reaches 0.80–1.10 m (2.62–3.61 ft). Outdoors in temperate zones, expect 1.00–1.40 m (3.28–4.59 ft). Thanks to its Think Fast lineage, it handles cooler nights better than most photoperiods—great for September harvests in the Northern Hemisphere.

After Harvest: Heavy Buds, Bold Flavor, Fast Turnaround

You’ll notice dense, frosty buds with deep green hues, purple accents, and orange pistils. The yield? Up to 500 g/m² (16.3 oz/ft²) indoors or 600 g (21.16 oz) per plant outdoors under ideal conditions. The aroma—earthy, diesel, with unmistakable garlic and spice—fills the room during cure.

Maintenance is minimal: just flush 7–10 days before harvest, dry at 18–22°C (64.4–71.6°F) and 50–60% RH, then cure in jars for 2–4 weeks. The result? Smooth, complex smoke with layered savory-sweet notes.

Short- and Long-Term Advantages and Benefits

• Harvest in just 7–8 weeks of flowering—faster than most photoperiods.

Frequently Asked Questions

Is GMO Fast an autoflower?

No—it’s a fast-flowering photoperiod strain. You must switch to a 12/12 light cycle to trigger bloom, but it finishes much faster than standard photoperiods.

Can I grow GMO Fast outdoors in a cold climate?

Yes! Its fast finish makes it one of the best photoperiods for temperate or short-season regions. Just plant after last frost and aim for a September harvest.

Does it really smell like garlic?

Absolutely. The savory, pungent garlic-diesel aroma is its signature—intensified during curing. Not for the faint of nose!

What’s the best way to maximize yield indoors?

Use SCROG with 9 plants/m² in 11L pots, train early, and maintain 40–50% humidity in flower. Add Green Planet Dense Bud Compactor in mid-flower for tighter buds.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown GMO Fast twice—once in a 1m² tent and once outdoors in northern Spain. Indoors, I used SCROG with 12L pots and harvested 470 g/m² after 8 weeks of flower. The smell was intense (thank god for my carbon filter!), but the buds were rock-hard and dripping in trichomes. Outdoors, it finished September 12th—just before the rains—and yielded 550 g per plant. My tip? Don’t overfeed nitrogen in flower; this strain loves a clean finish. I used Canna Flush for 10 days pre-harvest, and the smoke was smooth with zero harshness. The garlic-diesel flavor is wild—like smoking a gourmet spice rack. Not for beginners, but if you want fast, potent, and unforgettable, GMO Fast delivers.
