Jealousy Z XL Auto® by Sweet Seeds – High-Yielding Autoflower with Diesel & Citrus Aroma

Jealousy Z XL Auto® by Sweet Seeds is a high-octane autoflowering strain that delivers big, frosty buds with a bold Diesel-citrus punch in just 8 weeks from seed to harvest.

Still stuck with slow, low-yielding autos?

Let’s be real: most autoflowers promise big but end up delivering small, airy buds and forgettable flavor. You’re left waiting weeks for a harvest that barely covers your costs — not to mention the dull, one-note taste that makes every hit feel like a compromise.

Why does waiting 10+ weeks for underwhelming resin make you mad?

Because you know your setup deserves better. You’ve seen the trichome bombs online — dense, purple-streaked colas that reek of fuel and orange peel. But your current strain just can’t keep up. It stretches too much, needs constant tweaking, and still underperforms. And let’s not talk about the smell — weak, grassy, zero complexity. You’re not growing just to pass time. You’re chasing that next-level experience, and average genetics won’t get you there.

The upgrade: Jealousy Z XL Auto® hits fast, hard, and aromatic

Meet your new go-to autoflower: a 6th-gen powerhouse from Sweet Seeds that packs 20–25% THC, finishes in 8 weeks, and floods your grow space with a complex terpene storm of Sour Diesel, ripe orange, and earthy spice. This isn’t just another auto — it’s a yield monster with soul. From week one, it grows with purpose: thick stems, tight internodes, and a structure built to hold massive, resin-drenched buds. Whether you're indoors or on the balcony, it adapts fast and delivers consistent, top-shelf results without the fuss.

Why Jealousy Z XL Auto® outperforms your current strain

Forget the trial-and-error of unstable genetics. Jealousy Z XL Auto® was bred for performance, not just potency. It doesn’t just grow fast — it grows smart. With a balanced 56.3% Indica / 43.3% Sativa structure, it fills space efficiently, resists stress, and transitions seamlessly into flowering. You’ll notice the difference from day one: no excessive stretching, no weak branches, no mystery deficiencies. Just solid, predictable growth that lets you focus on what matters — maximizing flavor, density, and resin production. And when harvest time hits, you’re not just cutting down a plant. You’re harvesting a statement.

Key features you’ll notice from the first grow

• Finishes in just 8 weeks from germination — no more 10+ week waits.
• Produces dense, trichome-covered buds with a pungent Diesel-orange aroma.
• Reaches 0.50–1.30 m (1.64–4.27 ft) — compact enough for stealth, tall enough for serious yields.
• Shows purple and reddish hues late in flowering — adds visual appeal and terpene depth.
• Thrives both indoors and outdoors with yields up to 650 g/m² (1.43 lb/ft²) or 200 g (7.05 oz) per plant.
• Boasts 20–25% THC — delivers a strong, balanced high without overwhelming sedation.
• Low Ruderalis content (0.4%) — behaves more like a photoperiod in structure and potency.

Who this strain is perfect for

Jealousy Z XL Auto® isn’t for casual growers who just want a few grams. It’s for those who demand quality, consistency, and character in every harvest. Whether you're a solo grower maximizing a small tent or a collector curating rare terpene profiles, this strain earns its spot.

• Growers who want fast, high-THC harvests without sacrificing flavor.
• Urban cultivators needing discreet, compact plants with big returns.
• Connoisseurs chasing complex terpene profiles — Diesel, citrus, spice, earth.
• Outdoor growers in Mediterranean or temperate climates looking for resilient, high-yielding autos.
• Collectors who appreciate stable, 6th-gen genetics from a trusted breeder like Sweet Seeds.

How to grow Jealousy Z XL Auto® for maximum results

Keep it simple, keep it effective. This strain rewards good basics, not gimmicks.

• Start strong: Germinate in a moist, dark environment at 22–25 °C. Use a light, well-aerated medium like Light Mix Peat Free 50L by Bio Bizz for optimal root development.
• Pot smart: Move to a final pot of 18–27 L (5–7 gal) early — this auto doesn’t like being repotted twice.
• Light cycle: Run 18–20 hours of light daily from seed to harvest. No switching needed.
• Nutrition: Start mild and increase gradually. In flowering, support bud development with a bloom booster like Alga Bloom by Plagron.
• Training: Light LST is fine, but avoid topping or FIM — autos don’t recover well from stress.
• Climate: Keep temps at 22–26 °C in veg, 20–25 °C in flower. Maintain 40–50% RH in late flowering to prevent mold.
• Harvest: Look for milky-to-amber trichomes. Flush 7–10 days before cutting for a smoother smoke. Dry slowly at 18–22 °C and 50–60% RH, then cure for 2–4 weeks.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autos, but Jealousy Z XL Auto® stood out immediately. I grew it side-by-side with a well-known photoperiod strain in my 1.2 x 1.2 m tent under 600W LED, and it kept up in every way — density, smell, potency. The buds were rock-hard, covered in trichomes, and turned a gorgeous purple in the last two weeks. The high? Perfect balance — creative and uplifting at first, then smoothly transitioning into deep relaxation. No couch lock, just pure zen. I paired it with Plagron Mega Worm in a coco mix, and the root development was insane. If you want an auto that doesn’t feel like a compromise, this is it.
