Extreme Impact Auto Heavyweight Seeds – High-Yield Autoflowering Indica for Relaxation & Sleep

Extreme Impact Auto from Heavyweight Seeds is a powerhouse autoflowering indica designed to deliver a massive, resinous harvest and a deeply relaxing, sedative effect in record time. This strain is your shortcut to heavy yields and a heavy-hitting smoke.

Ever started an autoflower expecting big things, only to end up with a wispy plant and a disappointing yield? It's frustrating to invest weeks of care and energy for a harvest that barely fills a jar. That feeling of "is this even worth it?" can kill your growing buzz fast. But what if your next auto could be different? What if you could grow a plant so robust and productive it rivals photoperiod strains, all while finishing in just 8 weeks?

Why Extreme Impact Auto is Actually Worth It for You

This strain solves the classic autoflower dilemma: speed vs. substance. It combines the fast, hassle-free cycle of an auto with the yield and potency you'd expect from a much longer veg period. Its genetics are a strategic heavyweight bout: Mazar Auto brings the dense, resinous bud structure and classic indica power, while Fast & Vast Auto injects incredible speed and yield potential. The result is a plant that grows with vigorous, bushy structure, packing on weight rapidly during its short flowering phase. It's the perfect balance for growers who want impressive results without a long commitment, whether you're a beginner looking for a surefire win or a pro maximizing space with a quick-turnaround crop.

Typical Objections and Clear Answers

Let's tackle the common doubts head-on.

• You think autos can't yield as much as photos. In reality, Extreme Impact Auto is bred specifically to break that mold, with indoor yields rivaling many photoperiod strains.
• You worry it will be too difficult for a first-time grower. In reality, its high resistance and forgiving nature make it an excellent choice for beginners. For a perfect start, consider using a Seedbox Plagron germination kit to ensure strong, healthy seedlings.
• You're concerned about the potency not being "serious." In reality, with 21% THC and a 90% indica genetic background, the effects are profoundly potent and physically heavy, perfect for unwinding.
• You fear a bland, generic autoflower taste. In reality, the complex hash and citrus terpene profile provides a classic yet exciting flavor that stands out from many other autos.

How to Grow It Safely and Effectively

Follow these steps for a stress-free grow and maximum results.

1. Start Smart: Germinate seeds in a warm (22-25°C / 71-77°F), humid environment. Transplant into its final, large pot (18-27 L / 4.8-7.1 gal) early to avoid stunting this fast auto.
2. Provide Consistent Light: Run an 18/6 or 20/4 light schedule throughout its entire life. Strong, consistent light is key to triggering its massive bud production.
3. Feed Moderately: This plant is a heavy feeder during flowering but can be sensitive to overfeeding early on. Start with a light nutrient regimen and increase gradually. A product like Growth Booster can help during the vegetative stretch.
4. Manage Environment: Maintain good airflow and keep humidity around 40-50% during flowering to protect its dense buds. It thrives in temperatures of 20-25°C (68-77°F).
5. Harvest at Peak: It will be ready in about 8 weeks. Check trichomes; milky white with some amber will give the most sedative effect. Flush with plain water for the last 7-10 days.
6. Dry & Cure Properly: Dry buds slowly in a dark space at 18-22°C (64-72°F) and 50-60% RH for about 10-14 days, then cure in jars for 2-4 weeks to enhance flavor and smoothness.

Frequently Asked Questions

How long does Extreme Impact Auto take from seed to harvest?

Approximately 8 weeks (56 days) from germination. It's one of the faster finishing autoflowers, perfect for multiple harvests per year.

Is it suitable for outdoor growing?

Absolutely. Its resistance to mold and pests makes it a great choice for outdoor gardens in temperate to Mediterranean climates. It stays relatively short and bushy, offering some discretion.

Can I use training techniques like LST on this auto?

Yes, but be gentle. Light Low-Stress Training (LST) is recommended to open up the canopy and increase light penetration. Avoid heavy topping or fimming, as autos have a limited recovery time.

What's the best way to enhance its yield and resin production?

Focus on strong light, consistent feeding during flowering, and good environmental controls. In the final weeks, a bloom booster like Monster Bloom can help pack on extra weight and resin.

How strong is the smell during growth?

The smell is pronounced, especially in late flowering—spicy, hashy, and intense. Using a carbon filter in your indoor setup is highly recommended for discretion.

Personal Experience of Pevgrow’s CEO (Alan)

I've grown my fair share of autos promising the world, and many fall short. Extreme Impact Auto is different. The main doubt I had was whether an auto could truly deliver a "heavyweight" yield without sacrificing potency. This strain erased that doubt. From the moment it starts flowering, it bulks up with an almost aggressive speed. The buds become rock-hard, coated in frost, and the smell… it's a classic, spicy hash aroma that fills the room. The effect is exactly what you want from a heavy indica: a wave of relaxation that starts behind the eyes and spreads outwards, perfect for shutting down after a long day. My tip? Don't be shy with the pot size. Give it space, feed it well during the stretch and early flower, and then watch it do its thing. It's forgiving, but it rewards good care with an absolutely knockout harvest. For anyone skeptical about autoflower potential, this is the strain that will change your mind.
