Auto Jack Autoflowering Seeds – Paradise Seeds Sativa-Dominant Hybrid for Energetic Highs & Fast Harvests

Auto Jack by Paradise Seeds is a sativa-dominant autoflowering strain that brings the legendary energy of Jack Herer and the resin-rich power of White Widow into one fast, easy-to-grow plant. Expect uplifting effects, citrusy sweetness, and harvests in just 65–70 days.

Overwhelmed by complicated grows?

Let’s face it: not every strain plays nice with your schedule, space, or skill level. You want big flavor and strong effects, but without the stress of pH tweaks, light cycle switches, or mold panic.

Why waste time on finicky plants?

Most sativas take forever, stretch like crazy, and need expert care. Others fizzle out with weak highs or bland taste. You end up with mediocre buds, wasted time, and zero motivation to grow again.

Auto Jack: the no-stress sativa that actually delivers

This is where Auto Jack shines. It’s the autoflower version of the award-winning Jacky White, packed with 18% THC and a terpene profile rich in limonene and myrcene. It grows fast, stays manageable, and rewards you with sticky, aromatic colas—no green thumb required.

Less gear, more results

Auto Jack simplifies your grow from seed to harvest. No need for complex lighting schedules or vegging phases. Just plant, feed, and watch it thrive under 18–20 hours of light from start to finish. Its compact size and resilience mean fewer tools, less maintenance, and more confidence—especially if you're growing in a closet, balcony, or small tent.

• Keep 18–20h light daily—no change needed
• Use 18–27 L pots for full root development

Frequently Asked Questions

Is Auto Jack good for beginners?

Absolutely. Its autoflowering nature, resilience, and forgiving growth make it a top choice for first-time growers. Just keep the basics right—light, water, and nutrients—and you’ll be rewarded.

Can I grow Auto Jack outdoors in colder climates?

Yes. While it prefers mild conditions, Auto Jack adapts well to cooler northern regions thanks to its Ruderalis genetics. Just plant after the last frost and ensure it gets enough light.

Does it smell strong during flowering?

Yes, it has a medium to high odor—especially when the citrus and gassy notes develop. Use a carbon filter if growing indoors for discretion.

How many plants per m² should I grow?

For optimal light exposure and airflow, 4–6 plants per m² works best. If using LST, you can go up to 9 in a SCROG setup.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of autos, but Auto Jack stands out for its balance of speed, potency, and flavor. I ran 4 plants in 20L pots under a 600W LED, 18/6 light cycle. They stretched hard in pre-flower—up to 1.10 m—but responded well to low-stress training. By week 10, the room smelled like a citrus orchard. The buds were dense, frosty, and easy to manicure. I’ve used it during creative sessions and morning walks—it’s uplifting without anxiety. My only tip? Don’t overfeed. This strain hates nutrient burn. Stick to 70% of recommended doses and you’ll get smooth, flavorful smoke every time.
