Automatic Collection 3 by 00 Seeds – Autoflowering Cannabis Seeds for Fast, High-Yielding Grows

Automatic Collection 3 by 00 Seeds is your shortcut to fast, high-yielding autoflowering cannabis with minimal effort and maximum flavor. These compact, resilient plants thrive in any setup and deliver consistent results in just 70–85 days from seed to harvest.

Is your grow space a total mess?

Let’s be real: how many times have you lost a lighter, crushed a bud, or mixed up your strains because everything’s scattered across the table? Without a solid system, your grow or consumption zone turns into a cluttered jungle where good vibes go to die.

Chaos steals your chill — and your yield

Disorganization isn’t just annoying — it’s costly. Misplaced tools mean wasted time. Confused strains lead to wrong pairings. Overlooked humidity checks invite mold. And when your setup looks like a storm hit it, even rolling a joint feels like a chore. That daily friction kills your flow and turns a relaxing ritual into stress.

The 00 Seeds solution: order in 3, grow in peace

Automatic Collection 3 brings instant structure to your grow. With three carefully selected autoflowering seeds, you get uniform height, synchronized cycles, and predictable yields — no guesswork, no chaos. Everything starts clean, grows tight, and finishes strong. Just plant, maintain, and enjoy a streamlined process from germination to harvest.

How your grow space transforms with this pack

Just clean lines, easy access, and total control. With Automatic Collection 3, you eliminate guesswork and create a harmonious setup where every plant has its place — and so do you.

This uniformity means simpler lighting, better airflow, and easier training. You can automate watering, set one timer, and manage all three plants as a single unit. It’s not just growing — it’s growing smart.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autoflower packs, but Automatic Collection 3 stands out. I grew all three in my 1.20 m x 1.20 m (3.94 ft x 3.94 ft) tent under a 600W LED, and they finished within days of each other. The structure was bushy and even — perfect for SCROG. I used LST early and got double the bud sites. One surprise? The terpene punch. I expected smooth smoke, but the citrus-diesel kick was next-level. I now recommend this pack to anyone starting out or running a stealth setup. Pro tip: don’t top them. These autos hate stress — just bend and tie.

Yields were solid — around 500 g/m² (1.76 oz/ft²) — and the effects were perfectly balanced. Daytime clear-headed buzz, evening relaxation. No couch-lock. I cured them for three weeks, and the flavor deepened beautifully. If you want reliability, speed, and quality, this is your pack.
