Kryptonite Auto by Pyramid Seeds – Fast Sativa Autoflower with Haze Flavor & 22% THC

Kryptonite Auto by Pyramid Seeds is a lightning-fast, high-THC autoflowering sativa that delivers a powerful cerebral rush and authentic Haze flavor in just 65 days from seed to harvest.

Are you still waiting weeks too long for your sativa to finish?

Most sativas take forever to mature, tying up your space and energy with endless light cycles and fragile growth. You’re left waiting, wondering if it’ll ever pay off — and when it does, the yield or potency often disappoints.

What if you could grow a true sativa in under 10 weeks — without compromising on flavor or strength?

Imagine harvesting dense, resinous buds with that unmistakable Haze kick, all while freeing up your tent for the next round. No more 14-week waits. No more weak yields. Just fast, clean, energetic highs with zero guesswork.

Kryptonite Auto delivers sativa power on autoflower time

This 80% sativa beast hits hard with 22% THC, blooming in just 9–10 weeks with minimal effort. Compact at 0.60–1.60 m (1.97–5.25 ft), it’s perfect for small spaces or guerrilla grows. Indoors, expect up to 450 g/m² (15.87 oz/ft²); outdoors, harvest up to 200 g (7.05 oz) per plant under full sun.

What it feels like to grow and smoke Kryptonite Auto

From first sprout to final cure, Kryptonite Auto feels like a cheat code. The plant stays manageable, with tight internodes and a bushy structure that loves light. It resists mold and thrives in Mediterranean climates, making it a rock-solid choice for beginners. When you light it up, the flavor pops — citrus, pine, and earth with a sharp Haze bite. The high is uplifting, creative, and long-lasting: pure sativa clarity without anxiety or burnout.

How to squeeze the most out of Kryptonite Auto

• Start in its final pot (18–27 L) to avoid transplant stress.
• Use 18–20 hours of light daily — no photoperiod switch needed.
• Feed lightly; this strain hates nutrient burn.
• Apply low-stress training (LST) early to boost yields.
• Harvest when trichomes turn milky-white for maximum energy.
• Pair with Advanced Seeds genetics for next-level stability.
• Use a carbon filter if growing indoors — the aroma is medium-strong in late flowering.

Advantages and benefits in your day-to-day life

• Compact size means discreet growing — perfect for balconies or small tents.
• Fast 65-day cycle lets you fit 3–4 harvests per year outdoors.
• High THC delivers instant mental clarity for creative work or social vibes.
• Minimal maintenance frees up time — ideal for busy growers.
• Consistent performance builds confidence, especially for first-timers.
• Great return on investment: big flavor, big yield, small footprint.

How it fits with other products in your set-up

Kryptonite Auto thrives in organic soil mixes enriched with Worm Humus Biobizz, which boosts root development and terpene production. During flowering, a light PK booster like Hammerhead PK 4/12 can increase bud density without overwhelming this sensitive sativa. For stealth grows, pair it with a compact tent from our FloraDuo Grow line to maximize space efficiency.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Kryptonite Auto in my 1.20 m² (12.92 ft²) tent with a 600W LED, and it blew me away. At 1.40 m (4.59 ft) tall, it filled the space without stretching. I used a 20L pot and organic soil with Worm Humus Biobizz — the terps were insane. The high hit fast: clear-headed, creative, and social. I didn’t crash, and there was zero anxiety. I’ve tried dozens of autoflowering sativas, but this one delivers real sativa power without the wait. Pro tip: don’t overfeed. I went light on nutrients, and the plant rewarded me with 420 g (14.82 oz) of dense, frosty buds. If you want fast, clean, and potent — this is your strain.
