AK-420 Feminized Seeds – White Label’s Sativa-Dominant Powerhouse with Heavy Yields

AK-420 Feminized by White Label is a sativa-dominant powerhouse that merges legendary AK genetics with modern grower-friendly traits, delivering heavy yields, a complex citrus-pine aroma, and an uplifting cerebral buzz in just 50–65 days of flowering.

Ever feel like your grow space is stuck in slow motion—waiting weeks for dense, fragrant buds while your plants stretch unpredictably or underperform? You’re not alone. Many sativa-leaning strains promise energy and aroma but deliver airy colas, long waits, or finicky care that drains your time and patience.

That limbo of mediocre harvests and wasted effort gets old fast—especially when you’re craving that bright, creative spark without the hassle. You deserve a strain that actually finishes on time, fills your tent with resin, and rewards your effort with every puff.

Enter AK-420 Feminized: White Label’s refined take on the iconic AK family, engineered for speed, yield, and that unmistakable terpene punch. No males, no guesswork—just consistent, heavy harvests of lime-green, trichome-drenched buds that ignite your imagination.

What’s in the pack and what makes AK-420 special

You’re getting feminized seeds of a 35% indica / 65% sativa hybrid, born from Colombian, Mexican, Thai, and Afghani landraces. This isn’t just another AK clone—it’s a stabilized, high-performing version built for real-world grows.

• 100% feminized seeds: zero risk of male plants
• Genetic heritage: classic AK lineage with award-winning roots
• Bud structure: open, spear-shaped colas with bright orange pistils
• Trichome coverage: dense, diamond-like resin layer
• Terpene profile: terpinolene-dominant with citrus, pine, floral, and spicy notes

How your grow game levels up with AK-420

No more guessing when to harvest—its 50–65-day flowering window is tight and reliable. And thanks to its airy bud structure, airflow stays strong, slashing mold risk even in humid late-flower stages. You’ll spend less time worrying and more time admiring those heavy, glistening colas.

Frequently Asked Questions

Is AK-420 good for beginners?

Absolutely. Its low difficulty, fast flowering, and resilience to minor errors make it perfect for first-time growers. Just avoid overwatering and ensure good airflow during flowering.

How tall does AK-420 get indoors?

Typically 0.80–1.40 m (2.62–4.59 ft). Use topping or SCROG to control height and boost yield.

Does it smell a lot during flowering?

Yes—expect strong floral-pine-citrus notes in the last 2–3 weeks. A carbon filter is highly recommended for indoor grows.

Can I grow it outdoors in cooler climates?

It prefers warm, sunny conditions. In cooler zones, start early and use greenhouse protection to ensure full maturation by early October.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of AK variants, but AK-420 Feminized stands out for its balance. Last summer, I ran two plants in a 120x60 cm tent—topped twice, trained with SCROG. They finished in 62 days with 480 g/m² of frosty, lime-green buds that smelled like a pine forest dipped in lemon zest. The high? Pure creative fuel—perfect for writing or jamming with friends. My tip: don’t skip defoliation around week 3 of flower; those open colas let light penetrate and prevent mold. And yes, it’s forgiving—I accidentally overfed one plant early on, and it bounced back without issue. For the price, it’s one of the smartest buys in our White Label collection.
