Worried your autoflower won’t pack flavor or power?

Let’s be real: too many autoflowers taste like hay and hit like a warm breeze. You invest weeks, space, and effort, only to end up with bland buds and a forgettable high. It’s frustrating—especially when you’re counting on quality.

And if you’re growing outdoors, the fear of mold, weak yields, or slow finishes can keep you up at night. You don’t want to gamble your grow on a strain that looks good on paper but underperforms in practice. That’s the last thing you need.

Auto Melon Gum isn’t another ‘meh’ auto. It’s a flavor bomb with serious power, bred from legendary Lavender and Bubblegum genetics. It finishes early (50–57 days), resists common stressors, and produces rock-hard, resin-drenched buds that smell like a fruit market and taste even better. This is the auto that actually delivers.

Why Auto Melon Gum delivers more than just fast results

This isn’t just a quick grow—it’s a high-quality one. You get the best of both worlds: speed and substance. The genetics from Soma Seeds’ Lavender and Serious Seeds’ Bubblegum mean you’re not sacrificing taste or potency for speed. In fact, you’re gaining it. Whether you're tight on time or just hate waiting, Auto Melon Gum rewards you with dense, colorful flowers and a high that starts uplifting and gently melts into deep relaxation. It’s fun with friends, perfect for chilling solo, and absolutely worth growing again.

• Early finish (50–57 days): Harvest fast without sacrificing quality—ideal for multiple outdoor cycles or quick indoor turns.
• Massive outdoor yields: Up to 900 grams per plant (2.95 lb) in optimal conditions—turn your garden into a fruit forest.
• Resin-rich buds: Crystal-covered flowers with vibrant purple, red, and blue hues—great for extracts or show-off smokes.
• Indica-dominant fun: A balanced high that’s social at first, then deeply relaxing—perfect for evening use.

Common doubts—clear answers

You might have questions. Let’s clear them up:

• You think that autos don’t taste good. In reality, Auto Melon Gum’s Lavender x Bubblegum lineage delivers one of the most flavorful profiles in the autoflower world.
• You think that fast means weak. In reality, it packs very high THC and produces long-lasting, memorable effects.
• You think that big yield means big stink. In reality, while it’s aromatic, proper airflow or a carbon filter keeps it discreet.

How to grow Auto Melon Gum for best results

Keep it simple and let the genetics shine. This auto thrives when you avoid overcomplicating things—no aggressive pruning, no extended veg.

1. Start with a final pot of 18–27 L (4.75–7.13 gal) to avoid transplant stress.
2. Use well-aerated soil or coco; consider adding MYCOPLANT at transplant to boost root resilience.
3. Provide 18–20 hours of light daily—no photoperiod switching needed.
4. Water lightly at first, increasing as the plant grows; avoid overwatering during stretch.
5. Ensure strong airflow and ventilation, especially in flowering, to protect dense buds.
6. Flush 7–10 days before harvest to improve flavor and smoothness.
7. Cure buds slowly (60% RH, 18–22°C) for 2–4 weeks to maximize terpene retention.

Frequently Asked Questions

Does Auto Melon Gum need a lot of nutrients?

No, it’s moderate in demand. Start low and increase gradually—overfeeding can harm resin production.

Absolutely. Full-spectrum LEDs work great. Keep the light 40–60 cm (15.75–23.62 in) above canopy during flowering.

Is it mold-resistant for humid climates?

It has moderate resistance, but dense buds need good airflow. Avoid high humidity in late flowering to prevent issues.

Will it stretch a lot during flowering?

It has a moderate stretch. Keep lighting consistent and support branches if needed during early flower.

Personal Experience of Pevgrow’s CEO (Alan)

I was skeptical at first—another 'melon' strain? But Auto Melon Gum surprised me. I grew it in my outdoor setup in southern Spain, no fancy gear. Just sun, basic soil, and HESI Root Complex at the start. By week 7, it was a monster—thick, colorful, and sticky as hell. The smell? Like walking into a candy store. I shared a joint with friends and the buzz was instant: giggly, warm, then deeply chill. No anxiety, no couch-lock. Just pure, clean fun. If you want an auto that actually tastes and hits like a photoperiod, grow this. It’s now in my regular rotation.
