Jackpot Auto Feminized Seeds · Heavyweight Seeds · Fast Autoflowering with Jack Herer Genetics

Jackpot Auto by Heavyweight Seeds is the ultimate autoflowering strain for growers who want premium quality without the wait or the fuss, delivering a potent, resin-packed harvest in record time.

Ever feel like growing top-shelf cannabis is a full-time job, demanding constant attention and perfect conditions just to get a mediocre yield? You're not alone. Many autoflowering strains promise ease but deliver weak genetics and underwhelming results, leaving you with more effort than reward. That's the frustrating gamble of cheap autos.

Jackpot Auto changes the game. This isn't just another auto; it's a meticulously crafted cross of the legendary, sativa-dominant Jack Herer and the ultra-fast, high-yielding 2 Fast 2 Vast, stabilized with robust Ruderalis. The result? A plant that grows itself. You get the legendary flavor and cerebral punch of Jack Herer, wrapped up in a compact, autoflowering package that finishes in just 60-70 days from seed. No light schedule changes, no guesswork—just consistent, heavy yields of sticky, trichome-covered buds, whether you're on a sunny balcony or in a cozy tent.

Your Shortcut to a Premium Harvest

Forget the months-long commitment of photoperiod plants. Jackpot Auto is your express lane to harvest. Its Ruderalis genetics mean it flowers based on age, not light cycles. This translates to a set-and-forget growing experience. Simply provide 18-20 hours of light from start to finish, and watch it explode into a resin factory. It's the perfect choice for first-timers, busy growers, or anyone with limited space, as it stays a manageable 0.80–1.00 m (2.62–3.28 ft) tall. You can even grow multiple cycles per year outdoors in mild climates.

How to Grow Jackpot Auto for Maximum Returns

To unlock Jackpot Auto's full potential, follow this simple, effective guide.

1. Start Smart: Germinate your seeds in a warm, humid environment (22-25°C). For a vigorous start that minimizes transplant shock, consider using a root stimulator when you move the seedling to its final pot.
2. Let It Ride: Plant directly into its final container (11-20 L / 2.9-5.3 gal) to avoid stunting its autoflowering clock. Use a light, airy substrate and maintain a consistent light schedule of 18-20 hours on.
3. Fuel the Growth: During its short vegetative phase, feed with a balanced, gentle nutrient formula. Avoid heavy nitrogen feeds later on.
4. Support the Bloom: As flowering begins around week 3-4, reduce humidity to 40-50% and ensure good airflow to protect those dense buds. A carbohydrate and terpene booster during mid-flower can enhance bud density and flavor.
5. Harvest Perfectly: Watch the trichomes. Harvest when most are milky white for a more energetic high, or wait for some amber for a heavier, relaxing effect. Flush with plain water for the last 7-10 days.

Care and Feeding for Optimal Results

Jackpot Auto is a hungry plant during its short life. Use a balanced fertilizer schedule tailored for autoflowers, starting at half strength and increasing as the plant matures. Maintain a pH of 6.0-6.5 in soil. Good ventilation is crucial, especially in late flower, to prevent mold in those thick colas. For the best results, pair it with a high-quality coco or soil substrate that offers excellent drainage and aeration.

Frequently Asked Questions

Is Jackpot Auto good for beginners?

Absolutely. Its autoflowering nature eliminates the need to change light cycles, and its robust genetics make it forgiving of common beginner errors like slight overwatering or less-than-perfect nutrient schedules.

How much does Jackpot Auto yield?

Indoors, you can expect 600-800 g/m² (1.96-2.62 oz/ft²). Outdoors, each plant typically yields 50-80 g (1.76-2.82 oz), but with optimal conditions and a large enough pot, you can hit even higher numbers.

What does Jackpot Auto smell like while growing?

The aroma is pungent and complex, blending spicy, earthy Jack Herer notes with sweet, fruity undertones. A carbon filter is recommended for indoor grows to manage the strong scent during the final weeks.

Can I top or heavily train Jackpot Auto?

It's best to avoid topping or other high-stress training techniques, as autos have a fixed lifecycle and recovery time is limited. Low-Stress Training (LST) is highly effective for maximizing light exposure and yield.

When is the best time to plant Jackpot Auto outdoors?

You can plant once the danger of frost has passed and nighttime temperatures consistently stay above 10°C. In many climates, this allows for spring, summer, and even early autumn harvests.

Personal Experience of Pevgrow’s CEO (Alan)

I've run Jackpot Auto in both my personal tent and our test gardens, and it consistently impresses me. For an autoflower, the flavor retention from the Jack Herer parent is remarkable—that classic spicy, sandalwood punch is definitely there. I grow it in 15 L (4 gal) pots of coco under 18/6 light, and it barely stretches, making it perfect for a sea of green setup. The yield is honestly shocking for its size; the buds are rock hard and absolutely caked in resin. My pro tip? Don't overfeed it early. Go light on nutrients for the first two weeks, then hit it with a balanced bloom booster. The only con is the smell in late flower—it's a dead giveaway, so keep that carbon filter running. All in all, if you want a no-brainer auto that actually tastes and feels like a premium photoperiod strain, Jackpot is a sure bet.
