ShotGun Auto Seeds – Pure Instinto | Fast AK-47 Hybrid · 23% THC

ShotGun Auto by Pure Instinto is a high-performance autoflowering cannabis seed designed to deliver explosive yields and a potent 23% THC punch in record time. By crossing the legendary AK-47 with a robust Ruderalis, this strain guarantees a lightning-fast 8 to 9-week cycle from sprout to harvest, offering you top-tier, resin-drenched buds without the hassle of changing light cycles.

When you settle for cheap, unverified autoflower genetics, you are setting yourself up for a disappointing harvest. Low-quality seeds often struggle to germinate, grow into flimsy plants that can't support their own weight, and ultimately produce airy, flavorless buds that leave you needing to pack another bowl just to feel a buzz. You end up running your lights for months only to harvest a stash that barely lasts a few weeks.

Think about the real cost of that mediocre run. You are burning cash on electricity, premium soil, and expensive nutrients, not to mention the daily time and effort spent checking pH levels and watering. When harvest day finally arrives and you are left with a handful of fluffy, weak flowers, that sinking feeling of wasted time and money hits hard. It is incredibly frustrating to invest your soul into a grow tent only to realize the genetics were rigged against you from day one.

ShotGun Auto is the bulletproof solution that balances premium quality, rugged durability, and massive performance. These seeds earn every penny of their price tag by developing thick, sturdy stems capable of holding dense, heavy colas without snapping. In just 55 to 60 days, you get a reliable, heavy-hitting stash that maximizes your grow space and nutrient investment, proving that top-shelf genetics are the smartest way to guarantee a profitable and satisfying harvest.

Advice on how to grow the seed

Quick overview: Auto · Pure Instinto · 55–60 days cycle approx. · Low difficulty · Ideal for compact indoor spaces.

Safe start: Germinate at 22–25 °C and plant directly into the final pot.

• Use an 18 L (4.76 gal) fabric pot for maximum aeration.
• Keep humidity around 65–70% for the first week.
• To ensure explosive root growth, apply Canna Rhizotonic XP early on.
• Water sparingly in a circle around the seedling to encourage root stretching.

Directed growth: Maintain an 18/6 light cycle throughout the entire grow.

• Keep temperatures between 22–26 °C.
• Apply gentle LST to open up the canopy to light.
• Never top or aggressively prune this fast-flowering auto.
• Explore other elite genetics from Pure Instinto if you love vigorous hybrids.

Efficient flowering: Watch for pre-flowers around week 3 or 4.

• Drop relative humidity to 40–50% to prevent mold in dense buds.
• Ensure strong airflow above and below the canopy.
• For rock-hard, heavy colas, add Brutal Sucrox Gram + during peak bloom.
• Keep feeding light; AK-47 genetics can be sensitive to nitrogen toxicity.

Harvest and refinement: Flush the substrate 7–10 days before chopping.

• Harvest when trichomes are mostly milky with 10-15% amber for a balanced high.
• Dry slowly at 18–20 °C and 50–55% RH for 10–14 days.
• Cure in glass jars for at least 3 weeks to unlock the sweet citrus terpenes.

Tricks to get the most out of it without overspending

To maximize your return on investment with ShotGun Auto, the secret lies in environment control rather than expensive bottled nutrients. Because this strain has a short vegetative window, any stress will stunt its growth and reduce your final yield. Focus on dialing in your VPD (Vapor Pressure Deficit) and providing intense, high-quality LED lighting for 18 hours a day.

• Skip the transplant: Sow the germinated seed directly into its final 18 L (4.76 gal) pot to avoid transplant shock and save on intermediate plastic pots.
• Go easy on the nitrogen: This strain doesn't need heavy veg nutes; a light, high-quality soil will carry it through the first 3 weeks for free.
• Invest in airflow: A cheap clip-on fan prevents mold in those thick, pungent buds, saving your entire crop from the trash bin.

Frequently Asked Questions

How long does ShotGun Auto actually take from seed to harvest?

Under optimal indoor conditions with an 18/6 light schedule, this strain is ready to chop in just 55 to 60 days (8 to 9 weeks) from the moment the seed sprouts.

How often is it worth running this strain in a perpetual harvest?

Because of its lightning-fast cycle, you can easily fit 5 to 6 consecutive runs per year in a single tent. It is highly profitable for growers who want a constant, uninterrupted supply of premium buds.

Does the pot size affect the final yield and profitability?

Absolutely. Using a smaller pot will restrict root growth and trigger early flowering, resulting in a smaller plant. Using an 18 L (4.76 gal) fabric pot ensures the roots have enough space to support the maximum yield of up to 500 g/m² (1.64 oz/ft²).

Personal Experience of Pevgrow’s CEO (Alan)

When I look at what you get for what you pay, ShotGun Auto is an absolute steal. I ran a couple of these in a spare 1x1 m (3.28x3.28 ft) tent just to test the speed, and I was blown away by how thick the main stalks got. You usually have to baby autos or tie them up late in flower, but these girls held up their fat, frosty colas like champions. It’s a bargain because you spend less time waiting, less money on nutrients, and zero effort on structural support.

I think this strain is perfect for the impatient grower or anyone looking to fill their jars quickly between longer photoperiod runs. My personal tip? Don't overfeed them. The AK-47 lineage is robust but prefers a lighter touch with the EC meter. Give them good light, a breezy environment to keep mold away from those dense nugs, and they will reward you with some of the most uplifting, citrusy smoke you’ve ever vaped.
