Skunk #1 Automatic Seeds – Sensi Seeds’ Legendary Hybrid, Fast & Easy Autoflowering Grow

Skunk #1 Automatic Seeds by Sensi Seeds bring the legendary hybrid power of a Cannabis Cup winner into a fast, easy, and compact autoflowering grow—perfect for beginners and seasoned growers who want quality without the hassle.

Are you tired of complicated grows and underwhelming harvests?

Maybe you’ve tried other autos that promised big yields but delivered weak flavor or spindly buds. Or perhaps you're new to growing and feel overwhelmed by light cycles, nutrient charts, and pruning schedules. You just want something that works—something that grows strong, smells amazing, and gives you a satisfying, balanced high without needing a PhD in botany.

And when your plant finally flowers, only to collapse under mildew or stretch too tall for your space, it’s not just disappointing—it kills your motivation. You start wondering if growing is even worth it.

Enter Skunk #1 Automatic. This isn’t just another autoflower—it’s a direct descendant of one of the most awarded cannabis lines in history, now perfected for simplicity and resilience. With minimal effort, you get thick, resin-coated buds, a deliciously pungent aroma, and a high that’s both uplifting and deeply relaxing. No light timers to stress over, no weeks of vegging—just plant, feed, and harvest in under 10 weeks.

Before planting Skunk #1 Automatic

You’re probably thinking: “Is my space ready? Do I need special gear? Will it smell too much?” The good news: this strain thrives in simple setups. Whether you're using a small tent, a balcony, or a greenhouse, Skunk #1 Automatic adapts easily. Just make sure you’ve got a well-draining pot (18–27 L is ideal), quality soil, and a spot with decent airflow.

• Choose a final pot early—autos hate being transplanted
• Use light, airy soil with good aeration
• Keep humidity around 60–70% during germination
• Start with 18–20 hours of light daily
• Germinate seeds in a moist paper towel or directly in soil

During the grow: watch it thrive

From day one, Skunk #1 Automatic shows its vigor. Within 3 weeks, it starts flowering automatically—no switch needed. The plant stays compact, reaching 0.80–1.10 m (2.62–3.61 ft), making it perfect for stealth grows. You’ll notice dense branching and tight bud sites forming early.

During flowering, reduce humidity to 40–50% to prevent mold, especially in humid climates. This strain is resistant to cold and handles temperature swings well, but a carbon filter helps control its strong, skunky smell during late bloom.

Feed steadily but avoid overloading—this plant rewards consistency, not excess. Around week 5, you’ll see trichomes glistening like morning dew. That’s when you know you’re on track for a top-shelf harvest.

After harvest: flavor, effect, and next steps

Once dried and cured (2–4 weeks at 55–60% RH), your buds will explode with earthy sweetness and that unmistakable sharp skunk punch. The high? A smooth wave of cerebral euphoria that melts into full-body relaxation—ideal for unwinding after work or enhancing creative downtime.

Yields average 450–550 g/m² (15.87–19.40 oz/ft²) indoors and 50–150 g/plant (1.76–5.29 oz/plant) outdoors, depending on care. Maintenance is minimal: just clean your tools and store seeds in a cool, dark place for next season.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autos, but Skunk #1 Automatic stands out for its reliability and flavor. I planted four seeds in 20 L pots on my balcony in April—no fancy gear, just basic LED lights and organic soil. By week 9, they were dripping with resin. I didn’t train them much—just a little LST to open up the canopy.

The smell during drying was intense—like walking into a 90s headshop. But after curing for three weeks, it mellowed into this rich, earthy-sweet profile that’s pure nostalgia. The high is smooth: first a spark of creativity, then a deep body melt. I use it to unwind after long days, and it never fails to reset my mood.

One tip: don’t overwater. These plants hate soggy roots. And skip the heavy nutrients—this strain shines with a light hand. I paired it with Cancerbero Mycorrhizae and saw faster growth and better resilience. If you want a no-stress grow with legendary results, this is your seed.
