AK 48 Autoflower – Nirvana Seeds · Indica-Dominant Hybrid with Fruity Flavor & Balanced High

AK 48 Autoflower by Nirvana Seeds is a fast, resilient, and beginner-friendly indica-dominant hybrid that delivers a balanced high, rich terpene profile, and impressive yields in just 11–13 weeks from seed to harvest.

Are you stuck with slow, finicky plants that barely survive?

Maybe you're tired of strains that demand perfect conditions, complex light schedules, and constant monitoring—only to underdeliver on flavor, yield, or effect. You want something that just works: a plant that grows strong without babysitting, stays under the radar, and still gives you a high-quality, flavorful smoke.

Without the right genetics, every grow feels like a gamble

Weak yields, mold outbreaks, or inconsistent effects can kill your motivation. You waste time, money, and space on plants that stretch too tall, smell too loud, or take forever to finish. And if you're growing in a hot or humid climate, your crop could collapse before harvest. The stress isn’t worth it—especially when you just want a reliable, satisfying experience without the hassle.

AK 48 Autoflower solves it all with stealth, speed, and stability

This automatic hybrid from Nirvana combines the legendary AK-48 with hardy Ruderalis to create a compact, fast-finishing plant that thrives in tough conditions. It grows to just 0.80–1.10 m (2.62–3.61 ft), stays discreet, and finishes in 77–91 days with zero light schedule changes. Whether you're growing on a balcony, in a closet, or outdoors in Southern Europe, AK 48 Autoflower delivers dense, resinous buds with a smooth, fruity-floral taste and a clear-headed yet relaxing high.

Before planting AK 48 Autoflower

Get ready for a low-stress grow that fits any space. This strain doesn’t need a big tent or complex setup—just a sunny spot and basic care. Plan for a short cycle, so you can start anytime and harvest multiple rounds per year.

• Choose a 18–27 L pot for maximum root development
• Use well-draining soil or coco with good aeration
• Set up 18–20 hours of light daily—no switching needed
• Keep temperatures at 22–26 °C and RH at 60–70% during germination
• Pair with Nirvana Seeds for consistent genetics and proven performance

During growth: watch it thrive with minimal effort

AK 48 Autoflower grows fast and bushy, with strong side branching and a compact structure. It doesn’t stretch much, so it’s perfect for small spaces. The plant develops dense, frosty buds with a sweet, earthy-citrus aroma that’s noticeable but not overwhelming.

• Water when the top inch of soil feels dry
• Apply mild nutrients early—avoid overfeeding
• Use LST gently to open up the canopy
• Avoid topping or FIM—autoflowers don’t recover well
• Ensure good airflow to prevent humidity buildup

After harvest: enjoy consistent quality and smooth effects

Once cured, the buds deliver a balanced high—euphoric and focusing, yet physically relaxing. You’ll notice improved mood, creativity, and stress relief without heavy sedation. The flavor is smooth, with berry and floral notes and a hint of sweet hash. Maintenance is minimal: just clean your tools and store seeds in a cool, dark place for next time.

• Harvest when trichomes turn milky to slightly amber
• Dry slowly at 18–22 °C and 50–60% RH for 7–10 days
• Cure in jars for 2–4 weeks, burping daily
• Store in airtight containers away from light and heat
• Reap up to 400 g/m² (1.3 oz/ft²) indoors or 120 g (4.23 oz) per plant outdoors

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown AK 48 Autoflower three times now—twice indoors in a 1.20 x 1.20 m tent under 600W LED, and once outdoors on my south-facing balcony in Barcelona. Every time, it’s been rock-solid. I used 20L pots with a soil-coco mix and kept it simple: 18/6 light, mild nutrients, and light LST to open the canopy. No topping, no drama. It stayed under 1m, finished in 12 weeks, and produced dense, trichome-covered buds with a smooth, fruity punch. The high is clear and uplifting at first, then gently relaxing—perfect for afternoon sessions or winding down after work. I especially love how it handles heat; even in 35°C summers, it didn’t flinch. I’d grow it again in a heartbeat, especially for quick turnarounds or stealth setups. My only tip? Don’t overfeed it—this strain prefers a light hand on the nutrients.
